Referring to FIG. 5 , it shows a flow chart of the steps of Embodiment 5 of a file transfer method of the present invention. In this embodiment of the present invention, the first terminal device is the sender of the target file resource, and the second terminal The device is the recipient of the target file resource, and the first terminal device and/or the second terminal device may be a mobile device or a computing device, wherein the computing device is a device that can run according to a program and automatically and high-speed process Smart electronic devices with massive amounts of data, such as desktop computers, laptops, etc. The mobile device is a computing device that can be used on the move, such as a mobile phone, and the embodiment of the present invention does not need to limit the types of the first terminal device and the second terminal device.

Embodiments of the present invention may include the following steps:

Step 501: Obtain the corresponding target file resource on the side of the first terminal device according to the file resource selection instruction issued by the user;

In a preferred embodiment of the present invention, the file resource selection instruction may be a download instruction for a certain file resource selected by the user from the file resource download list displayed on the first terminal device side. Specifically, a first client program is installed on the side of the first terminal device, and a large amount of free file resources are displayed in the first client program for users to download, and users can download from the file resources of the first client program Select your favorite file resources to download. In practice, when the user selects a file resource he or she likes in the download list of file resources displayed by the first client program through a mouse or touch operation, a corresponding file resource download instruction is generated, and the first client program receives After the file resource download instruction is received, the corresponding file resource is downloaded from the server as the target file resource and stored on the side of the first terminal device.

In practice, the first client program opens a floating window on the computer side for the transmission of target file resources. Specifically, the function of the floating window is to prompt the user when the window of the main program is minimized. You can see the running status of the program, and you can quickly open the main program window by clicking on these small windows. The floating window includes a preset entry that can be accessed by the user. After the floating window is displayed on the screen, the user can access preset content or perform preset operations through the preset entry. For example, the user can start the operation of sending a file by clicking a preset entry.

In another preferred embodiment of the present invention, the instruction for selecting a file resource may be an instruction for selecting a certain file resource selected by the user from the file resources stored on the side of the first terminal device. Specifically, the user may also select a certain file resource from existing file resources stored on the first terminal side as the target file resource.

As a preferred example of this embodiment, the target file resource has file attribute information, and the file attribute information may include the size of the target file resource, the type of the target file resource, the version number of the target file resource, the logo and so on. Wherein, the type of the target file resource may include various types such as theme, wallpaper, ringtone, software, music, game, video, and e-book.

Step 502, when the second terminal device wirelessly accesses the first terminal device, send the target file resource to the file server through the floating window on the side of the first terminal device;

Specifically, after the first terminal device obtains the target file resource, the first terminal device uses the first client program to detect whether there is a second terminal device accessing, and if there is a second terminal device accessing , the first client program detects whether the user initiates a specified operation on the floating window. Wherein, the specified operation initiated for the floating window can be in various ways. Referring to the schematic diagram of the specified operation for the floating window shown in FIG. 6, as a preferred example of this embodiment, the specified operation initiated by the user for the floating window can be It includes an operation for the user to drag the target file resource to the floating window, that is, an operation for the user to directly drag the target file resource to the floating window after selecting the target file resource from the file resources stored on the first terminal side. As another preferred example of this embodiment, the specified operation initiated by the user on the floating window may include the user clicking a file selection button on the floating window, and selecting the target file resource in the file path selection window popped up by the first terminal device The operation of the path, for example, the file selection button can be the function button of "select the file to be sent" shown in Figure 6, after clicking the file selection button, the first terminal device side will pop up a file path selection window, The user can select the path of the target file resource in the file path selection window.

When the first client program detects that the user initiates a specified operation on the floating window, it sends the target file resource to the first server side according to a sending instruction triggered by the user. In practical applications, there are many ways for the user to trigger the sending instruction. For example, you can click on a similar function button such as "send file" to realize the sending of the target file resource; or, if the first terminal device is equipped with a gravity sensing device , the gravity sensing device may also be triggered by shaking the first terminal device, so as to realize the sending of the target file resource. In the embodiment of the present invention, the shaking can be understood as being able to trigger any operation of the gravity sensing device, such as shaking the mobile device up and down or left and right, and the embodiment of the present invention does not limit the specific operation.

In a preferred embodiment of the present invention, after receiving the sending instruction sent by the user, step 502 may further include generating a file sending request on the first terminal device side according to the user's specified operation on the floating window; A terminal device side sends the file sending request to the file server; the first terminal device side receives the file response message returned by the file server; the first terminal device side sends the target file according to the file response message Resources are sent to the file server.

Specifically, the file sending request may include the size of the target file resource. After receiving the file sending request, the file server judges whether its own memory size is larger than the size of the target file resource according to the size of the target file resource. , if greater than, the file server returns a file response message to notify the first terminal device to upload the target file resource; otherwise, the file server does not return a file response message. If the first terminal device receives the file response message within the preset time period, it will send the target file resource to the file server according to the file response message; if the first terminal device does not receive the file response message within the preset time period If a file response message is received, the target file resource is not sent to the file server, and at this time, the target file resource is in a state of waiting to be sent in the floating window.

In practice, in order to ensure the security of the target file resource, before uploading the target file resource, the first client program may encrypt the target file resource according to a first preset rule before uploading it to the file server. The first preset rule may be an encryption and decryption rule pre-agreed between the first client program and the background server.

In a specific implementation, the second terminal device can associate with the first terminal device by scanning the two-dimensional code on the first terminal device to wirelessly access the first terminal device, and the process can be (taking the first terminal device as Computing device, the case where the second terminal device is a mobile device is an example):

First, the computing device receives the notification message of establishing a persistent connection sent by the mobile device, and the notification message includes the identification of the mobile device; if the computing device allows the establishment of a persistent connection, the computing device sends the identification of the mobile device and the identification of the computing device to the application server, The application server records the association relationship between the mobile device and the computing device in the association relationship list.

Specifically, establishing an association relationship between the mobile device and the computing device mainly includes the following steps:

1. The mobile device is authenticated on the application server;

1.1 Start the second client program (i.e. mobile assistant) on the mobile device;

1.2 After entering the mobile phone number on the mobile device, the mobile device sends the device's IMEI and mobile phone number to the application server;

1.3 The application server sends a text message with an authentication code to the mobile device;

1.4 Enter the authentication code on the mobile device and send it to the application server;

1.5 The application server determines that the identity of the mobile device is owned by the mobile device according to the authentication code, the mobile device number and the IMEI.

2. At the Computing Device

2.1 Start the mobile assistant on the computing device;

2.2 After inputting the mobile phone number of the mobile device, the computing device sends the mobile phone number and MID of the mobile device to the application server;

2.3 The application server inquires in the database whether the mobile device corresponding to the mobile phone number has been authenticated at the application server according to the received MID and mobile phone number of the computing device. If it is authenticated, the computing device is established in the association list The corresponding relationship between the MID, mobile phone number, and the IMEI of the mobile device, for example, store them as a record in the association list; otherwise, send an invitation to the mobile device, and the invitation process is as follows:

2.3.1 The application server sends an invitation message to the mobile device, and the invitation message contains an activation link address;

2.3.2 When the mobile device receives the text message, a binding permission dialog box will pop up. After the user clicks OK, the information in the activation link will be sent to the application server. After receiving the binding confirmation request, the application server will send the The mobile device is bound to the corresponding computing device.

The relationship list structure is

Specifically, the identifier of the mobile device is mobile1, and the identifier of the computing device is desktop1. When the mobile device wants to associate with the computing device, the persistent connection sends the association request to the computing device. After the computing device agrees to confirm, the association mobile1<- ->desktop1 is established.

In practical applications, the first terminal device obtains the identity of the second terminal device through the notification message of the persistent connection by using the first client program, and establishes an association relationship between the identity of the first terminal device and the identity of the second terminal device Afterwards, a pop-up window may pop up asking the user whether to remember the identity of the second terminal device (as shown in Figure 7), if the user selects "OK" to indicate that the identity of the second terminal device is remembered, then in the A remember mark is added to the association between the identifier of the first terminal device and the identifier of the second terminal device, so that when the second terminal device is not connected to the first terminal device with a data line, the first terminal device automatically wirelessly Connect to the second terminal device; if the user selects "Let's talk later", the automatic connection function will not be enabled, and the next time the logo of the second terminal device accesses the first terminal device again, the user will be asked again whether to record If the user selects "Never Remind", the function of automatic connection will not be enabled, and the next time the logo of the second terminal device accesses the first terminal device again, it will not Then ask the user whether to remember the identifier of the second terminal device.

In a specific implementation, when the second terminal device wirelessly accesses the first terminal device, the second terminal device needs to be in an online state, and whether the second terminal device is online depends on the network state obtained through monitoring. Specifically, in a preferred embodiment of the present invention, if the second terminal device is a mobile device installed with an Android system, it monitors the network status in the following manner:

The network status is a SystemService, which can be obtained through context.getSystemService(Stringname). When the network status changes, SystemServic will send out an android.net.conn.CONNECTIVITY_CHANGE broadcast. At this time, the mobile device only needs to register a service (service). Then you can receive broadcasts of network status changes in the background. This service can be ConnctionChangeReceiver; process the received broadcasts. The implementation method is as follows. Add network status judgment in onReceive:

ConnectivityManager connectMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo mobNetInfo = connectMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE); NetworkInfowifiNetInfo = connectMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

Among them, ConnectivityManager is to obtain the current system service information;

getNetworkInfo obtains the information of the two networking modes of MOBILE and WIFI respectively;

Determine the current networking status by judging the Boolean value returned by mobNetInfo.isConnected() and wifiNetInfo.isConnected(). If the returned Boolean value is true (or 1), it means that the current network is available and the mobile device can be connected; if it returns The Boolean value of is false (or 0), indicating that the current network is unavailable and the mobile device cannot be connected.

In another preferred embodiment of the present invention, if the second terminal device is a computing device, it monitors the network status as follows: if the computing device needs to connect to the network wirelessly, it can call the network interface API to obtain the current network status , if the current network status is available, the computing device connects to the current network, otherwise, does not connect to the current network.

Step 503, the file server generates the download address of the target file resource and returns it to the first terminal device side;

Specifically, the file server is a server for sharing files and is used to store target file resources. In practical applications, only the target file resources in the preset time period are stored in the file server, and the file server can periodically or irregularly detect the stored target file resources. If the time exceeds the preset time period, the target file resource is deleted. Wherein, the preset time period may be the time period set for the start time for the deposit time of each target file resource (such as one month, and the target file resource exceeding the deposit time for one month will be deleted); or, The preset time may also be a time limit uniformly set by the file server for all stored file resources (for example, target file resources stored before July 10, 2013 will be deleted).

After the file server receives the target file resource, it obtains the storage address of the target file resource on the file server side, generates the download address of the target file resource according to the second preset rule from the storage address, and generates the download address of the target file resource for the target file resource. The download address is encrypted according to the first preset rule and returned to the side of the first terminal device.

In a specific implementation, the user can select one or more target file resources and send them through the floating window. At this time, the first terminal device can use the first client program to generate a file sending list, and the file sending The list is a list organized by target file resources sent through the floating window, and the first terminal side displays the file sending list at a preset position of the floating window or other preset positions on the interface of the first terminal device. The file sending list includes file sending state information for each target file resource, and the file sending state information may include a successful sending state, a sending state, a waiting state for sending, and a sending failure state. Wherein, the file sending state information refers to the state information that the file is sent to the file server, and the successful sending state is the state of receiving the corresponding download address returned by the file server within a preset time period; the sending failure state is The status of the corresponding download address returned by the file server is not received within the preset time period.

In practical applications, viewing guide information may also be displayed in the file status list, and the viewing guide information is used to guide the user on how to receive and view file resources in the second terminal device.

Step 504, constructing an information packet of the download address of the target file resource, the file attribute information, and the identification of the second terminal device on the first terminal device side, and sending it to the application server;

Applied to the embodiment of the present invention, after receiving the download address of the target file resource returned by the file server using the first client program, the first terminal device side decrypts the download address of the target file resource according to the first preset rule, and then An information packet of the download address of the target file resource, the file attribute information, and the identification of the second terminal device is constructed, and the information packet is encrypted using a first preset rule and then sent to the application server.

In practice, if there are multiple second terminal devices wirelessly accessing the first terminal device side, the identifications of the multiple second terminal devices can be displayed to the user on the first terminal device side for the user to choose to receive The second terminal device for the object file resource.

It should be noted that the information package is actually a data structure that records the download address of the target file resource, the file attribute information, and the identifier of the second terminal device.

Step 505, the application server receives the information packet, and acquires the identifier of the first terminal device;

Specifically, after receiving the information packet, the application server decrypts it, obtains the identifier of the first terminal device, and records the mapping relationship of the identifier of the first terminal device<-->information packet file1.

In addition, after the application server decrypts the information packet to obtain the identity of the second terminal device, it generates an information confirmation instruction, and sends the information confirmation instruction to the first terminal device through a push server (push server), and the information confirmation instruction Including the identification of the second terminal device, the information confirmation instruction is used to inform the first terminal device to confirm whether to send the target file resource to the identification of the second terminal device.

After receiving the information confirmation instruction, the first terminal device may use the first client program to display the identity of the second device to which the target file resource will be sent to the user in the form of a pop-up window, etc., if the user selects "send immediately ", indicating that the user confirms that the target file resource is sent to the identifier of the second terminal device, and then the first terminal device side generates first confirmation information and sends it to the application server side. In addition, if the user's intention is not to send the target file resource to the identifier of the second terminal device, the user can select a button with words such as "changing the device", and the first terminal device side generates a second confirmation message to send To the application server, at this time, the user can connect the second terminal device that needs to receive the target file resource to the first terminal device to receive the target file resource; if the user does not access any second terminal device, the application server will Check whether there are other identifiers of the second terminal device associated with the identifier of the first terminal device in the association relationship list, and if so, respectively obtain the identifiers of the second terminal devices that have been connected to generate information and send the confirmation instruction to On the side of the first terminal device, ask the user whether to confirm sending the target file resource to the identifier of the second terminal device, and if the user confirms to send the target file resource to the identifier of the second terminal device, the first terminal device Automatically connect the identifier of the second terminal device for file transfer; on the other hand, if there is no other identifier of the second terminal device associated with the identifier of the first terminal device in the association list, the application server generates a connection The reminder message is sent to the first terminal device side to notify the user to connect to the second terminal device that needs to accept the target file resource.

Step 506, generating a file acquisition message on the application server side according to the identifier of the second terminal device and sending it to the push server;

After receiving the first confirmation information sent by the first terminal device, the application server generates a file acquisition message according to the identifier of the second terminal device, and sends the file acquisition message to a push server (push server). Wherein, the file acquisition message is used to notify the push server to send the file acquisition message to the second terminal device corresponding to the identifier of the second terminal device, so as to notify the second terminal device to obtain the information from the application server Bag.

Step 507, the push server sends the file acquisition message to the side of the second terminal device corresponding to the identifier of the second terminal device;

In practice, the push server is used to push the file acquisition message to the corresponding second terminal device. Specifically, after the push server receives the file acquisition message, it acquires the identifier of the second terminal device carried in the file acquisition message, and among the identifiers of all connected terminal devices (the terminal device will Automatically connect to the push server) to search for a terminal device with the same identifier as the second terminal device, and directly send the file acquisition message to the second terminal device.

Step 508: Obtain the corresponding information package from the application server according to the file acquisition message on the side of the second terminal device;

Specifically, a second client program is installed on the side of the second terminal device, and the second terminal device uses the second client program to receive the file acquisition message sent by the push server, and when receiving the file acquisition message , the file acquisition message can be displayed in the preset display position of the second terminal, and the user is notified of the availability of file resources in the form of a prompt sound or a pop-up window. After the user clicks on the file acquisition message, the second terminal device is prompted to use the The second client program obtains information packets from the application server.

Step 509, downloading the corresponding target file resource from the file server according to the download address of the target file resource at the second terminal device side;

After obtaining the information packet, the second client program decrypts the information packet, obtains the download address of the file resource in the information packet, and obtains the corresponding target file resource from the file server according to the download address of the file resource.

Further, after the second client program decrypts the information package, it can also obtain the type of the target file resource, and perform the following operations according to the type of the target file resource: if the type of the target file resource is a theme, wallpaper, ringtone, music, video, e-book, etc., then store the target file resource on the second terminal device side; if the type of the target file resource is an installation type such as software and/or games, directly install the target file resource Describes the object file resource. After the second client program has finished storing or installing file resources, it can notify the user of the installed file resources or stored file resources in the form of a notification message or a pop-up window at a preset display position on the interface of the second terminal device. file information, wherein the file information can be displayed in the form of a list.

Step 510: Generate file reception response information on the second terminal device side according to the target file resource and send it to the application server, and the application server sends the file reception response information to the first terminal side through the push server .

Specifically, after the second terminal device acquires the target file resource, it generates file reception response information and sends it to the application server, wherein the file reception response information includes the identifier of the first terminal device, and the application server sends the file reception response information to the application server through the push server. The file receiving response information is sent to the first terminal device side corresponding to the identifier of the first terminal device, and the file receiving response information is used to notify the first terminal device that the second terminal device has successfully received the target file resource. At this time , the first terminal device may generate a prompt message to notify the user according to the file reception response information.

In the embodiment of the present invention, when the first terminal device and the second terminal device are transferring file resources, the first terminal device may first send the file to the file server for storage, and after receiving the file download returned by the file server After the address, the download address is sent to the application server for storage, and the application server sends a message to notify the second terminal device to download the file to the file server.
