According to the file transmission method provided by the embodiment of the application, the file which is indicated by the file name and needs to be transmitted is obtained through the file transmission system, and then the file is transmitted by using the first transmission protocol. That is to say, in the technical solution, the first system that uses the first transmission protocol for transmission does not need to develop a corresponding transmission protocol module, but uses the first protocol in the file transmission system for transmission.

It can be understood that the method can effectively reduce the development cost.

For example, when there are 4 first systems all needing to transmit a file in a first transmission protocol, for the prior art, modules of the first transmission protocol need to be developed in the 4 first systems respectively; in the scheme, the 4 first systems do not need to develop modules of the first transmission protocol, only the modules need to be developed once in the file transmission system, and then the 4 modules can be transmitted by using the first transmission protocol in the file transmission system.

Detailed Description

For understanding, the relevant terminology referred to in this application will be first described.

1、DMZ

The quarantine zone (DMZ), also called an extranet zone, is a buffer between the insecure system and the secure system, which is set up to solve the problem that the external network cannot access the internal network server. The buffer zone is located within a small network area between the enterprise internal network and the external network. Some server facilities such as enterprise Web (Web) servers and forums that must be exposed may be placed within this small network area. The visitor of the external network can only access the service in the DMZ, but can not contact the information stored in the internal network, and the information in the internal network can not be influenced even if the server in the DMZ is damaged, so that compared with a common firewall, the DMZ area is arranged, one more barrier is provided for the attacker from the external network, and the internal network is protected more effectively.

The DMZ is better than a barrier, and an external network server is placed in the DMZ, so that the safety of an internal network is effectively guaranteed while the DMZ provides services for external network users.

2. MIS region

Refers to a company's internal system deployment area that has direct access to the extranet area and accesses the extranet through the extranet area.

3. Data exchange platform

The data exchange platform is an information exchange platform which is constructed by integrating a plurality of application information systems which are constructed in a scattered way and a computer network, and enables a plurality of application subsystems to transmit and share information/data, thereby improving the utilization rate of information resources. The data exchange platform has multiple functions of storage, forwarding, management and the like, and can realize data file exchange among main branches, among branches and between a peripheral system and a core system.

4、FTP

The File Transfer Protocol (FTP) is a set of standard protocols used for file transfer on a network, is a protocol for transferring files between two computers on a transmission control protocol/internet protocol (TCP/IP) network, is one of the earliest protocols used on a TCP/IP network and the internet, and belongs to an application layer of a network protocol group. The client-side needs to go through the three-way handshake process before establishing connection with the server, so that the connection between the client-side and the server is reliable, connection-oriented, and reliable guarantee is provided for data transmission.

FTP allows a user to communicate with another host in the form of file operations, such as addition, deletion, modification, retrieval, transfer, etc., of files. However, the user does not really log on the computer which the user wants to access, so that the user becomes a complete user, the FTP program can be used for accessing remote resources, and even though the two computers are possibly provided with different operating systems and file storage modes, the functions of file transmission, directory management, e-mail access and the like can be realized.

Fig. 1 is a schematic structural diagram of a transmission system according to an embodiment of the present application. As shown in fig. 1, the transmission system includes a system 101 and a system 102, where the system 101 includes a plurality of first systems, and any one of the plurality of first systems can perform file transmission with the system 102.

Wherein, the system 101 can be a sender during file transmission, and the system 102 is a receiver during file transmission; or system 101 may be the recipient of the file transfer and system 102 may be the sender of the file transfer. The embodiment of the present application does not limit this.

Taking the system 102 as an example of a receiving party, it is understood that a client of a certain user in the system 102 may receive a file sent by any first system in the system 101, or may receive a file sent by any first system in the system 101 by a file system in the system 102. The embodiment of the present application does not limit this.

In this application, the first system is also referred to as a file system, and may be understood as a system including a plurality of files. The plurality of file systems may be a plurality of file systems obtained by classifying information stored in files, for example: the files in the first file system store information about the amount of the transaction, the files in the second file system store information about the employees inside the bank, and so on.

For ease of understanding, the embodiments in this application are described with system 101 as the sender and system 102 as the receiver. However, it should be understood that the embodiments in the present application are also applicable to the case where the system 102 is used as a sender, and the embodiments in the present application are not limited thereto.

At present, if any file system in the system 101 is to perform file transfer with the system 102, a corresponding transfer protocol module needs to be developed on the file system.

At this time, for the system 101, if each file system included therein needs to perform file transfer with the system 102, a transfer protocol module needs to be developed on each file system, resulting in an increase in development cost.

As an example, it is assumed that the system 101 includes 10 file systems, and different types of data are stored in the 10 file systems, for example, the file system 1 stores daily transaction data in a bank, and the file system 2 stores partner company data, and the like. If all of the 10 file systems need to perform file transfer with the system 102, and the same transfer protocol, such as hypertext transfer protocol (HTTP), is used for the transfer of the 10 file systems, an HTTP protocol module needs to be separately developed for each of the 10 file systems, so that the development cost is very high.

In addition, the existing file transmission mode is that data interaction is directly performed between the system 101 and the system 102, and this mode has security risks. For example, an attacker of the extranet is very likely to invade the inside of the system 101, thereby leaking some highly confidential data inside the system 101.

In view of this, an embodiment of the present application provides a file transmission method, when a file system needs to transmit a file, the file system only needs to transmit the transmitted file to the file transmission system without developing a corresponding protocol module, and then the file transmission system transmits the file using a corresponding transmission protocol.

As an example, fig. 2 is a schematic structural diagram of a transmission system provided in an embodiment of the present application. As shown in fig. 2, a file transfer system 103 is provided between the systems 101 and 102, and when a file needs to be transferred in any first system in the system 101, the file is directly transferred by using a file transfer protocol in the file transfer system 103.

Further, in the embodiment of the application, by setting the DMZ and then deploying the file transmission system in the MIS area where the file system is located and the DMZ, potential safety hazards caused by direct interaction between the file system and the system 102 are effectively avoided, and the safety of data inside the system 101 is ensured.

Fig. 3 is a file transfer method according to an embodiment of the present application. The file transfer method may be executed by a file transfer system for performing file transfer between any of a plurality of first systems and a second system. As shown in fig. 2, the method of the embodiment of the present application includes S301, S302, and S303.

The first system in the embodiment of the present application is also referred to as a file system. The second system is a system for receiving a transmission file, and is the same as the system 102 in fig. 1 and 2, and the detailed description may refer to the related description in fig. 1 or 2, and is not repeated here.

S301, receiving a file name input by a user, wherein the file name is used for indicating a file needing to be transmitted.

The file name refers to the name of each file in the file system.

It will be appreciated that each file to be transferred has a corresponding name, so that the different files can be distinguished.

In the embodiment of the application, the type of the file name is not limited, for example, only one file name needs to be transmitted, and then the user can input the name; or there are two names of the files to be transferred, the user can input either one of the two names.

S302, obtaining target transmission files indicated by file names in a plurality of first systems, wherein at least two first systems in the plurality of first systems need to use a first transmission protocol to transmit the files.

Wherein the target transmission file represents a file indicated by a file name input by a user.

In this embodiment, after the file transfer system obtains the file name input by the user, the target transfer file to be transferred is obtained from the plurality of file systems.

In one implementation, the file transfer system may send a request message to each of the file systems, where the request message is used to request the file systems to send the target transfer file indicated by the file name. At this time, after receiving the request message, if the file system of the multiple file systems includes the target transmission file indicated by the file name, the file system may send the target transmission file to the file transmission system.

Alternatively, the file transfer system may send the request message to multiple file systems simultaneously. For example, there are 6 file systems in total, and the file transfer system may simultaneously send a request message to the 6 file transfer systems and then obtain the target transfer file.

Alternatively, the file transfer system may not send the request message to multiple file systems at the same time. For example, the file transfer system first sends a request message to the first file system, and if a target transfer file sent by the first file system is received, the request message is not sent to other file systems. The embodiment of the present application does not limit this.

S303, the target transmission file is sent to the second system by using the first transmission protocol.

The first transmission protocol is a transmission protocol when the target transmission file is transmitted.

In this embodiment, after the target transfer file is obtained, the target transfer file may be sent to the second system using the first transfer protocol.

In one implementation, the file transfer system may be caused to transfer the target transfer file to the second system by inputting parameter values of the second system such as a server address, a port, a user name, a path of the received file, a recipient or a receiving mechanism, and the like into the file transfer system.

It should be noted that, in the embodiments of the present application, a type of a specific receiver that receives the target transmission file is not limited. For example, it may be a user client in the second system, or it may be a file system.

It can be understood that, in this implementation, if at least two first systems use the same transmission protocol, at this time, it is not necessary to develop the transmission protocol for both of the at least two first systems, and it is only necessary to develop the transmission protocol once in the file transmission system, and both of the at least two first systems can use the protocol in the file transmission, which greatly reduces the development cost.

As an optional embodiment, the file transfer system includes a transfer protocol of which the kind is greater than 1, and the method further includes: receiving configuration parameters input by a user, wherein the configuration parameters comprise a first parameter used for indicating that the target transmission file is transmitted by using a first transmission protocol.

It is understood that when there are a plurality of transfer protocols of the file transfer system, one transfer protocol must be selected if the target transfer file is to be transferred. Therefore, in the embodiment of the present application, when the file transfer system includes a transfer protocol of which the kind is greater than 1, it is determined to transfer the target transfer file using the first transfer protocol by receiving the first parameter input by the user.

For example, there are 6 file systems in total, and the file transfer system includes three protocols, i.e., SFTP, HTTP and HTTPs, and in this case, if a file in the first file system needs to be transferred, it needs to select which of the three protocols is used for the file to be transferred.

In one implementation, the user may select the protocol type for file transfer based on the size of the target transfer file, the transfer mode, and the transfer performance requirements. For example, if the file to be transmitted is greater than 1 million (M) and the file security requirement is low, the transmission protocol may be configured as FTP, and the transmission speed is fastest; if the file to be transmitted is larger than 1M and the file security requirement is high, the configurable transmission protocol is SFTP; if the file to be transmitted is less than 1M and the transmission mode is a special line mode or the safety requirement is not high, the configurable transmission protocol is HTTP; if the file to be transmitted is less than 1M and the transmission mode is the Internet mode or the file transmission security requirement is high, the configurable transmission protocol is HTTPS.

It should be noted that, the manner in which the user selects the protocol is merely an example, and the embodiment of the present application is not limited thereto.

It will also be appreciated that when the file transfer system includes more than 1 type of protocol, the development cost can be further reduced.

As an example, assume that there are 4 file systems, wherein the first file system and the second file system can use two types of transfer protocols when performing file transfer with the second system, one is HTTP, and the other is SFTP. When the third file system and the fourth file system are transmitted with the external system, the transmission protocol used is HTTPS. At this time, if the first file system and the second file system both need to use HTTPS to transmit files, there is no need to additionally develop an HTTPS protocol module for the first file system and the second file system, thereby reducing development cost. That is, each transfer protocol only needs to be developed once in the file transfer system, and other file systems can use the protocol in the file transfer system, thereby greatly reducing the development cost.

In the file transmission method provided by this embodiment, the file transmission system supports multiple transmission protocols, and can meet the performance requirements of various file transmissions. The development cost of each file system is reduced.

As an optional embodiment, the plurality of first systems are located in a first network, the second system is located in a second network, and a quarantine zone DMZ is included between the first network and the second network, and a part of the file transfer system is deployed in the first network, and a part other than the part is deployed on the DMZ.

As an example, as shown in fig. 4, the network is divided into three areas, the plurality of file systems are located in a first network (also referred to as MIS region network), the second system is located in a second network (also referred to as external network), and in this embodiment, a DMZ network is further included between the first network and the second network. Because the DMZ region has the characteristics that visitors of the external network can only access the DMZ and cannot contact information in the MIS region network, and the like, if the file transmission system is deployed on the first network and the DMZ, the potential safety hazard caused by direct interaction between the file system and the second system is effectively avoided, and the safety of the file system is ensured.

It can be understood that, because there is a great potential safety hazard when the file system in the MIS region directly interacts with the second system in the external network, in this embodiment, the file transfer system is deployed in the MIS region and the DMZ, so that the file system in the MIS region performs data interaction with the second system in the external network through the file transfer system, thereby avoiding the problem of direct interaction, and ensuring the security of the file system in the MIS region.

As an optional embodiment, when receiving the configuration parameters input by the user, the configuration parameters input by the user include a second parameter, where the second parameter is used to indicate encryption information when the target transmission file is transmitted, and the method further includes: encrypting the target transmission file by using the encryption information; accordingly, sending the target transfer file to the second system using the first transfer protocol includes: and sending the encrypted target transmission file to the second system by using the first transmission protocol.

It can be understood that the target transmission file may be intercepted during the transmission process, and if the target transmission file includes the secret information, the secret information may be leaked. Therefore, in the present embodiment, the target transmission file is encrypted by receiving the second parameter input by the user and then encrypting the target transmission file according to the encryption information indicated by the second parameter.

In one implementation, the file transfer system may encrypt the target transfer file using a user name and a password, where the second parameter that the user needs to input includes the user name and the password.

As an example, assuming that the content of the target transmission file is "abcdefg", the file transmission system uses a user name and password for encryption in such a way that the user name is used in front of the content and the password is used behind the content. Assume that the user name input by the user is "123", the corresponding password is "xiaoming 123", and at this time, the content of the encrypted target transmission file is "123 abcdefgxiaoming 123".

In another implementation, the file transfer system may encrypt the contents of the target transfer file using a key.

For example, the user may input a key path for key encryption, and then the file transfer system finds a corresponding key according to the key path to encrypt the content of the target transfer file.

According to the file transmission method provided by the embodiment of the application, the second parameter input by the user is received, and then the target transmission file is encrypted according to the encryption information indicated by the second parameter, so that the possibility that the content in the target transmission file is tampered in the transmission process is reduced, and the file transmission safety is improved.

As an alternative embodiment, when receiving the configuration parameters input by the user, the configuration parameters input by the user include a third parameter, and the third parameter is used for instructing the target transmission system to transmit the target transmission file at the specified time.

For example, there are 100 file systems, and at a certain moment, files in all 100 file systems need to be transmitted, and at this moment, if 10 files are transmitted simultaneously, a jam may occur, so the file transmission system in this embodiment may further receive a parameter for setting a file transmission execution time input by a user according to a user's requirement, so that a target transmission file avoids a peak period, and is executed at the time corresponding to a transmission task, thereby reducing an influence on other files with higher priorities.

Optionally, when receiving the configuration parameters input by the user, the configuration parameters input by the user may further include a fourth parameter, where the fourth parameter is used to indicate whether to send a feedback file to the target first system, where the target first system includes the target transmission file, and the feedback file includes a file that the second system responds to the target transmission file.

The file transfer apparatus shown in fig. 5 may be used to perform the file transfer method described in any of the foregoing embodiments. As shown in fig. 5, the file transmission apparatus 500 of the present embodiment includes a receiving module 501, configured to receive a file name input by a user, where the file name is used to indicate a file that needs to be transmitted; an obtaining module 502, configured to obtain a target transmission file indicated by a file name in a plurality of first systems, where at least two first systems in the plurality of first systems need to transmit the file using a first transmission protocol; a sending module 503, configured to send the target transmission file to the second system using the first transmission protocol.
