It should be understood that the numbers of terminal devices, networks and servers in Fig. 1 are only illustrative. According to the implementation needs, there can be any number of terminal devices, networks and servers.

Continuing to refer to FIG. 2 , a flow 200 of an embodiment of the method for obtaining information according to the present application is shown. The method for obtaining information includes the following steps:

Step 201, receiving information query request information sent through a virtual private network tunnel.

In this embodiment, the electronic device (such as the server 105 shown in FIG. 1 ) on which the method for obtaining information runs can receive the information query request sent through the virtual private network tunnel through a wired connection or a wireless connection. information, wherein the above-mentioned information query request information includes title information, source address and target address. It should be pointed out that the above wireless connection methods may include but not limited to 3G/4G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods known or developed in the future .

In the existing cloud network, the virtual private network gateway in the cloud network can only connect to one virtual private network gateway at the opposite end of the virtual private network tunnel. When a terminal device in the cloud network establishes a virtual private network connection with other terminal devices in multiple cloud networks, multiple relatively independent virtual private network tunnels need to be established on the terminal device, that is, the terminal device needs to Create multiple virtual private network gateways. Moreover, the transmission of information in the cloud network is through one end of the virtual private network tunnel to the other end. In this way, the terminal device in the cloud network can only obtain the information on the terminal device with which the virtual private network tunnel is established, but cannot obtain the information on the terminal device that has not established a virtual private network tunnel, resulting in the information on the terminal device in the cloud network The utilization rate is not high.

To this end, the present application can set a virtual private network gateway on the server 105, and the virtual private network gateway can perform information transmission with multiple terminal devices in the cloud network through a virtual private network tunnel. And receive information query request information sent by other terminal devices in the cloud network through the virtual private network tunnel. Wherein, the information query request information may include title information, source address and target address. The title information is the title of the target information that the terminal device that sends the information query request information wants to obtain; the source address is the address in the cloud network of the terminal device that sends the information query request message; the target address is the address of the target information in the cloud network. Since the target information is usually located on a terminal device in a certain cloud network, the target address may be the same as the address in the cloud network of the terminal device where the target information is located.

In some optional implementations of this embodiment, the above method may also include the step of constructing a tunnel table, and the above step of constructing a tunnel table may include the following steps:

In the first step, for each virtual private network tunnel in at least one virtual private network tunnel, set a number for the virtual private network tunnel, and receive an address sent from the opposite end of the virtual private network tunnel.

The virtual private network gateway set on the server 105 can establish virtual private network tunnels with other terminal devices in the cloud network. For each virtual private network tunnel, the server 105 can set a number for the virtual private network tunnel. Afterwards, the terminal device at the opposite end of the virtual private network tunnel can send its address in the cloud network to the server 105 . In this way, the server 105 can obtain the address of the terminal device at the opposite end of each virtual private network tunnel.

In the second step, a first corresponding relationship between each number and the address corresponding to the number is established, and a tunnel table is established through the first corresponding relationship.

After obtaining the address of the terminal device at the opposite end of each virtual private network tunnel, a first correspondence between each number and the address corresponding to the number can be established. Afterwards, a tunnel table including the first correspondence between numbers and addresses corresponding to the numbers may be established through the first correspondence. After obtaining the above tunnel table, the server 105 can communicate with corresponding terminal devices through different virtual private network tunnels. When information needs to be transmitted between different terminal devices that have not established a VPN tunnel, the server 105 receives the information, and transmits the information to the corresponding terminal device through the corresponding virtual private network tunnel according to the address contained in the information. That is, the server 105 can realize the relay transmission function of information in the cloud network.

In some optional implementations of this embodiment, the above method may also include the step of constructing an information lookup table, and the above step of constructing an information lookup table may include the following steps:

The first step is to receive an information sharing request.

It can be seen from the above description that in the existing cloud network, the utilization rate of information between terminal devices is not high. For this reason, after the server 105 establishes multiple virtual private network tunnels, each terminal device can send an information sharing request to the server 105 . Wherein, the information sharing request may include title information of the shared information and an address corresponding to the shared information. In this way, it is beneficial to improve the utilization rate of information between terminal devices.

In the second step, a second corresponding relationship between each title information and the address corresponding to the title information is established, and an information lookup table is established through the second corresponding relationship.

After receiving the information sharing request, the server 105 may establish a second correspondence between each title information and the address corresponding to the title information; then, establish an information lookup table through the second correspondence. That is, the information lookup table includes title information and addresses of information distributed on different terminal devices.

In some optional implementation manners of this embodiment, the above method may further include: sending the above information lookup table through a virtual private network tunnel.

After obtaining the information query table, the server 105 can send the information query table to the terminal device at the opposite end of the virtual private network tunnel through each virtual private network tunnel, so that the terminal device can query the information in the cloud network.

It can be seen from the above description that the server 105 can realize the relay transmission function of information in the cloud network. Combined with the information lookup table, the method of this embodiment can enable the terminal device in the cloud network to obtain information on the terminal device with which no virtual private network tunnel has been established, thereby improving the utilization rate of information in the cloud network.

Step 202, extracting the target address from the above-mentioned information query request information, querying the first number of the virtual private network tunnel corresponding to the above-mentioned target address in the tunnel table, and sending the above-mentioned information query request information through the virtual private network tunnel corresponding to the above-mentioned first number .

It can be seen from the above description that a tunnel table is stored on the server 105, and the tunnel table is used to represent the corresponding relationship between the number and the address of the virtual private network tunnel. The server 105 can query the number of the virtual private network tunnel corresponding to the target address in the tunnel table. The opposite end of the virtual private network tunnel corresponding to the number is the terminal device that the information query request information needs to reach (that is, the terminal where the target information corresponding to the title information is located. equipment). The server 105 may send the above information query request information through the virtual private network tunnel corresponding to the first number.

Step 203, receiving the result information corresponding to the information query request information sent through the virtual private network tunnel corresponding to the first number.

After receiving the information query request information, the terminal device at the opposite end of the virtual private network tunnel corresponding to the first number will modify the address in the information query request information; then, the terminal device can query the address corresponding to the title information in the information query request information. target information; finally, the modified address and target information are encapsulated into result information and sent to the server 105 through the virtual private network tunnel corresponding to the first number. Wherein, the above result information includes target information, update target address and update source address.

Step 204, query the second number of the virtual private network tunnel corresponding to the update target address in the tunnel table, and send the above result information through the virtual private network tunnel corresponding to the second number.

After receiving the result information, the server 105 may query the second number of the virtual private network tunnel of the update target address included in the corresponding result information in the tunnel table, and send the above result information through the virtual private network tunnel corresponding to the second number. Usually, the update target address in the result information is the same as the source address in the information inquiry request information; the update source address in the result information is the same as the target address in the information inquiry request information. That is, the virtual private network tunnel corresponding to the second number queried by the server 105 is the same virtual private network tunnel as the virtual private network tunnel when the server 105 receives the information query request information. In this way, the server 105 can return the result information to the terminal device that sent the information query request information, realizing the information transmission between the terminal devices that have not established a virtual private network tunnel in the virtual private network environment, and improving the virtual private network. Information transmission efficiency and utilization. In this process, the server 105 can be regarded as a relay station for information transmission under the virtual private network environment.

The virtual private network tunnel corresponding to the second number queried by the server 105 may not be the same virtual private network tunnel as the virtual private network tunnel when the server 105 receives the information query request information. For example, after terminal device A sends information to terminal device B through the virtual private network tunnel, terminal device B may also send corresponding information to terminal device C through the virtual private network tunnel.

The current terminal device (the terminal device receiving the information acquisition request information) can receive the information acquisition request information sent by other terminal devices. The information acquisition request information is used to instruct the terminal device that has established the virtual private network tunnel to obtain the specified target information on the virtual private network.

Step 302, in response to the title information of the above-mentioned target information existing in the information look-up table, set the address corresponding to the above-mentioned target information in the above-mentioned information look-up table as the target address, and set the local address as the source address.

After receiving the information acquisition request information, the terminal device may query the target information indicated by the information acquisition request information through the information query table. If the title information of the above target information exists in the information lookup table, it means that the target information exists on the virtual private network. Then, the terminal device can obtain the address corresponding to the title information of the target information from the information lookup table, set the address as the target address, and set the local address of the terminal device as the source address. Wherein, the above-mentioned information lookup table may be used to characterize the correspondence between title information and addresses corresponding to the title information.

In some optional implementation manners of this embodiment, the above method may further include: sending the local address through the above virtual private network tunnel.

Step 304, receiving the result information corresponding to the information query request information sent through the virtual private network tunnel, and parsing the target information from the result information.

After the information query request information is sent to the server 105, the server 105 will send the information query request information to the corresponding terminal device in the virtual private network, and receive the result information of the corresponding information query request information sent to the server 105 by the terminal device; Then send the result information to the current terminal device through the virtual private network tunnel. In this way, the terminal device that sends the information query request information can obtain information on other terminal devices in the virtual private network, which improves the transmission efficiency and utilization rate of information in the virtual private network. In this process, the server 105 can be regarded as a relay station for information transmission under the virtual private network environment.

Continuing to refer to FIG. 4 , a flow 400 of an embodiment of the method for obtaining information according to the present application is shown. The method for obtaining information includes the following steps:

Step 401, receiving information query request information sent through a virtual private network tunnel.

In this embodiment, the electronic device on which the method for obtaining information runs (such as the terminal device shown in FIG. 1 ) can receive information obtaining request information through a wired connection or a wireless connection, wherein the above-mentioned information query request Information includes header information, source address, and destination address. It should be pointed out that the above wireless connection methods may include but not limited to 3G/4G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods known or developed in the future .

The current terminal device in the virtual private network (the terminal device receiving the information query request information) can receive the information query request information sent through the tunnel of the virtual private network. The information query request information may include title information of the information (that is, target information) on the current terminal device.

Step 402, parse out the title information, source address and target address from the above information query request information, and set the source address and target address as the update target address and update source address respectively.

The current terminal device can parse out the title information, source address and target address from the information query request information. Wherein, the source address can be used to characterize the address on the virtual private network of the terminal device sending the information query request information; the target address can be the address of the current terminal device; the title information can correspond to the information on the current terminal device (ie target information) . Then, the current terminal device sets the source address and the target address as the update target address and the update source address respectively, so as to send information subsequently.

Step 403: Encapsulate the target information, update target address, and update source address corresponding to the above-mentioned title information into result information, and send the above-mentioned result information through the above-mentioned virtual private network tunnel.

The current terminal device can query the target information corresponding to the local corresponding title information, and then encapsulate the target information, update target address and update source address into result information; and then send the above result information to the terminal at the opposite end of the virtual private network tunnel through the virtual private network tunnel device (such as may be the server 105).

In some optional implementation manners of this embodiment, the above method may further include: sending the local address through the above virtual private network tunnel.

For terminal devices connected to the virtual private network, in order to transmit information on the virtual private network, the terminal devices need to send their respective addresses to the server 105 as described above, so that the server 105 can send corresponding information according to the address.

In some optional implementation manners of this embodiment, the above method may further include: sending an information sharing request through the above virtual private network tunnel.

The terminal device in this embodiment needs to provide target information. In order to realize the sharing of information on the virtual private network, the terminal device in this embodiment needs to provide the shared information first. It can be seen from the above description that the server 105 can be regarded as a relay station for information transmission in the virtual private network environment, therefore, the terminal device can send an information sharing request to the server 105 through the virtual private network tunnel. Wherein, the above-mentioned information sharing request may include title information of the shared information and an address corresponding to the shared information. After receiving the information sharing request, the server 105 can send the title information of the shared information included in the information sharing request and the address corresponding to the shared information to other terminal devices in the virtual private network, so that other terminal devices in the virtual private network can obtain These share information, so as to achieve the purpose of improving the utilization rate of information between terminal devices.
