Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It is noted that embodiments of the application and features of the embodiments may be combined with each other without conflict. The technical scheme of the application obtains, stores, uses, processes and the like the data, which all meet the relevant regulations of national laws and regulations.
The embodiment of the invention provides a data transmission system which can be used for data transmission among devices in different network areas.
In the embodiment of the invention, in the scenario of data transmission among devices in a cross-network area, due to the limitation of network access, when the network area is divided, a part of the network area is generally set to connect two different network areas, which is called an external connection area. And a transit server can be arranged in the external connection area so as to realize data transmission among devices in different network areas. Fig. 1 is a schematic diagram of an architecture of a data transmission system according to an embodiment of the present invention, in which a first terminal belongs to a first network area, a second terminal belongs to a second network area, and a transit server is disposed in an external connection area. In order to facilitate file transfer between different network areas, a first file server may be set in the first network area to store files required by the first terminal, and a second file server may be set in the second network area to store files required by the second terminal. The transfer server can respectively perform data transmission with the first terminal, the second terminal, the first server and the second server.
The embodiment of the invention provides a data transmission method, which can be executed by a transit server in the system architecture shown in fig. 1, as shown in fig. 2, and comprises the following steps:
S201: and receiving a first data transmission request sent by the first terminal, acquiring a transmission file and a target address of the first data transmission request, and inquiring a second terminal corresponding to the target address.
After receiving the first data transmission request sent by the first terminal, the transfer server can analyze the model of the first data transmission request to obtain a transmission file and a target address of the data transmission request, and the corresponding second terminal, namely the terminal equipment which needs to be interacted by the first terminal, can be determined through the target address.
When the transmission file is larger, the data transmission request is inconvenient to carry, at the moment, the first terminal can store the transmission file to the first file server and inform the transfer server through the first data transmission request, so that the transfer server obtains the transmission file from the first file server, and when the transmission file is smaller, the transmission file can be carried to the first data transmission request. Since the communication protocol used by the first terminal to send the first data transmission request when the transmission file is large and the communication protocol used by the first terminal to send the first data transmission request when the transmission file is small are different, how to acquire the transmission file can be determined by the communication protocol of the first data transmission file. The acquiring of the transmission file of the first data transmission request in this step may be performed as: acquiring a communication protocol of a first data transmission request to judge whether the communication protocol is a target protocol or not; if yes, extracting a transmission file identifier from the first data transmission request to acquire a transmission file from a server corresponding to the first terminal; if not, extracting the transmission file from the first data transmission request.
The target protocol may be a protocol used to send the first data transmission request when the transmission file is large, and specifically may be SFTP, NFT, and the like. The communication protocol used by the first terminal to send the first data transmission request when the transmission file is small may be HTTP or the like.
It should be noted that, based on the above processing procedure, when the transmission file is smaller or no transmission file is transmitted, the first terminal may use the same communication protocol to send the first data transmission request, so after determining that the communication protocol of the first data transmission request is not the target protocol in the above process, the transit server may also determine whether the first data transmission request carries the transmission file or not. In the embodiment of the invention, the data transmission request sent by the first terminal to the second terminal may or may not include the transmission file. Since the transmission file is required to be transmitted through the file server, the transfer server processes the first data transmission request including the transmission file and the first data transmission request excluding the transmission file differently.
Because the first data transmission request carries the transmission file through the encoding in the message header, in this step, after receiving the first data transmission request, the transfer server can identify the message header format of the first data transmission request to determine whether the message header format is a target format, where the target format may be the format of the message header when the data transmission request includes the transmission file; therefore, if the message header format of the first data transmission request is the target format, determining that the first data transmission request includes the transmission file, so that the transmission file can be extracted from the first data transmission request, and further executing the subsequent steps; if the message header format of the first data transmission request is not the target format, it is determined that the first data transmission request does not include a transmission file, so that a request format corresponding to the target address can be queried to generate a corresponding second data transmission request, and the second data transmission request is sent to the second terminal, so that data transmission of the first terminal and the second terminal is achieved.
S202: and responding to the fact that the first terminal and the second terminal belong to different network areas, inquiring a file server corresponding to the second terminal, and sending the transmission file to the file server.
After determining that the first terminal and the second terminal belong to different network areas, the transfer server can query a file server corresponding to the second terminal, namely, the second file server, so as to send the transmission file to the file server. The transfer server sends the transmission file to the file server corresponding to the second terminal, so that the second terminal can directly obtain the transmission file sent by the first terminal from the second server.
S203: and inquiring a request format corresponding to the second terminal to generate a second data transmission request based on the first data transmission request, and adding an identification of a transmission file for the second data transmission request.
The request formats during data transmission are different due to different implementation technical frameworks of different service systems. Therefore, in this step, the transfer server may first query the request format corresponding to the second terminal, and then convert the first data transmission request into the second data transmission request, that is, generate the second data transmission request. The transfer server may add an identifier of the transmission file to the second data transmission request, because the second data transmission request transmits data to the second terminal, and the second terminal needs to be notified to acquire the transmission file. Specifically, the identification of the transmission file may include a name of the transmission file, a storage path, and so on, which are parameters that are convenient for the second terminal to acquire.
Specifically, in the implementation of the present invention, various request formats may be preset to correspond to the request templates, so that corresponding data transmission requests may be generated based on the request templates. The generation of the second data transmission request in this step may be performed as: extracting a parameter value of a target parameter from the first data transmission request, and calling a request template corresponding to the request format to generate a second data transmission request based on the parameter value of the target parameter. Where the target parameter may be a parameter required for the data transfer request, e.g., source address, target address, etc.
S204: and sending the second data transmission request with the added identifier to a second terminal so that the second terminal obtains the transmission file from the file server.
The second terminal can acquire the identification of the transmission file from the second terminal, and further can acquire the file from the file server for processing.
After the second terminal obtains the transmission file, response information, namely first response information, can be returned to the first terminal, and after the transfer server receives the first response information, the transfer server can inquire about a request format corresponding to the first terminal, and then converts the response information into a corresponding second response information to be sent to the first terminal.
It should be noted that, in order to send the data transmission request, the relay server may configure a routing policy in advance, so when the relay server sends the second data transmission request to the second terminal in this step, the relay server may first invoke the routing policy based on the target, and then send the second data transmission request with the identifier added to the second terminal according to the routing policy.
In order to ensure the security of data transmission, in the embodiment of the invention, encryption and decryption operations can be performed on the transmitted data transmission request, and encryption and decryption keys can be preconfigured.
In the embodiment of the invention, when the first terminal and the second terminal do not belong to the same network area, the transfer server can transmit the transmission file of the first terminal to the second terminal through the file server, so that the file transmission is realized on the basis of the request forwarding between the first terminal and the second terminal, the functions of requesting and transmitting the file between different network areas are realized, and the data transmission requirement between systems is met.
In combination with the system architecture shown in fig. 1 and the embodiment shown in fig. 2, taking a smaller transmission file as an example, a data transmission method in the embodiment of the present invention is specifically described, as shown in fig. 3, where the method includes:
S301: the first terminal sends a first data transmission request to the transfer server.
S302: the transfer server extracts the transmission file from the message header of the first data transmission request.
S303: and the transfer server inquires a corresponding second terminal based on the target address in the first data transmission request, and acquires a corresponding second file server.

S307: and the second terminal acquires the transmission file from the second file server based on the second data transmission request.
S308: and the second terminal sends the first response information to the transfer server.
S309: the transfer server side inquires the corresponding request format of the first terminal, converts the response message into a corresponding second response message and sends the second response message to the first terminal.
In the embodiment of the invention, when the first terminal and the second terminal do not belong to the same network area, the transfer server can transmit the transmission file of the first terminal to the second terminal through the file server, so that the file transmission is realized on the basis of the request forwarding between the first terminal and the second terminal, the functions of requesting and transmitting the file between different network areas are realized, and the data transmission requirement between systems is met.
When the transmission file is too large or too many, the transfer server may set, for convenience of file transmission, that the transfer server includes a first transfer server corresponding to the first terminal, a second transfer server corresponding to the second terminal, and an intermediate file server associated with the first transfer server and the second transfer server. Fig. 4 is a schematic diagram of an architecture of a data transmission system according to an embodiment of the invention. Based on the embodiment shown in fig. 4, the first terminal may send a first data transmission request to the first transfer server, and the first transfer server may obtain, based on the first data transmission request, a transmission file from the first file server, and further query an intermediate file server associated with the first transfer server and the second transfer server, so as to send the transmission file to the transfer server for storage; then the first service end can convert the first transmission request into a format, generate a second data transmission request and send the second data transmission request to the second transfer service end, and the second transfer service end can acquire a transmission file from the intermediate file service end based on the second transfer service end after receiving the second data transmission request; and then the second transfer server can transmit the transmission file to the second file server and send a second data transmission request to the second terminal so that the second terminal can acquire the transmission file from the second file server.
In connection with the system architecture shown in fig. 4 and the embodiment shown in fig. 2, taking a larger transmission file as an example, a data transmission method in the embodiment of the present invention is specifically described, as shown in fig. 5, where the method includes:
