Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as 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.
FIG. 1 is a schematic diagram of an architecture of an electronic data exchange system according to an embodiment of the present invention. As shown in fig. 2, the electronic data exchange system 100 includes a master 101 and a slave 102. The method for electronic data exchange provided in the first aspect of the embodiment of the present invention is applied to the main control terminal 101, and correspondingly, the system for electronic data exchange provided in the third aspect of the embodiment of the present invention is also applied to the main control terminal 101. The method for electronic data exchange provided in the second aspect of the embodiment of the present invention is applied to the controlled end 102, and correspondingly, the system for electronic data exchange provided in the fourth aspect of the embodiment of the present invention is also applied to the controlled end 102. The electronic exchange system provided by the fifth aspect of the embodiment of the present invention is the electronic data exchange system 100 shown in fig. 1. It should be noted that the number of the master 101 or the slave 102 in fig. 1 may be one, or may be multiple.
According to an aspect of the embodiment of the invention, a method for electronic data exchange is provided, which is applied to a server. The method comprises the following steps: receiving a heartbeat request of a controlled end, and recording a server IP and a port number of the controlled end; establishing connection with the controlled terminal according to the server IP and the port number, generating a control instruction and sending the control instruction to the controlled terminal to configure protocol information of the controlled terminal; the protocol information includes: a data transfer protocol for exchanging electronic data; and exchanging electronic data with the controlled terminal based on the data transmission protocol. The method for electronic data exchange in this embodiment is applied to the main control end.
In the actual application process, before establishing the connection with the controlled end, whether the IP link of the server of the controlled end is normal or not may be checked. If not, communicating network problems with the maintenance personnel of the controlled end, and if normal, establishing connection with the controlled end according to the IP and the port number of the server of the controlled end.
In this example, the data transmission protocols of the controlled end and the master control end are both configured by the master control end, and the master control end and the controlled end exchange electronic data based on the data transmission protocols. The specific type of the data Protocol may be selectively set according to actual situations, for example, FTP (File Transfer Protocol), OFTP2 (odd File Transfer Protocol Version 2, a Transfer Protocol proposed by the odd organization for transferring EDI messages), and the like.
Compared with the prior art that both electronic data exchange sides need to support the same data transmission protocol, the electronic data exchange method and the electronic data exchange device can enable electronic data exchange to be carried out even if the communication protocols of the servers of the both electronic data exchange sides are different, and are high in safety.
In the actual application process, before the control instruction is sent to the controlled end, the master control end can be authenticated. Authentication refers to identifying whether the master control end has the authority to send a control instruction to the controlled end. For example, the master control end is authenticated through a verification code or a login password. And if the authentication is passed, the master control end sends a control instruction to the controlled end. Through authentication, the security of data exchange between the master control end and the controlled end can be improved.
The Transmission Protocol for the master Control end to send the Control command may be set manually, for example, the Control command is sent based on a TCP (Transmission Control Protocol).
Optionally, the protocol information further includes: communicating the test information; after generating a control instruction and sending the control instruction to the controlled end, the method further comprises the following steps: and performing connectivity test based on the connectivity test information, and confirming that the test is passed.
Illustratively, after the master control end generates the control instruction, the data transmission protocol and the connectivity test information of the master control end are configured according to the control instruction. After the master control end sends the control instruction to the controlled end, the controlled end configures a data transmission protocol and communication test information of the controlled end according to the control instruction. After the configuration is completed, the master control end sends a test file to the controlled end, and if the controlled end successfully receives the test file sent by the master control end, the communication channel from the master control end to the controlled end is communicated. After the configuration is completed, the controlled end also sends a test file to the main control end, and if the main control end successfully receives the test file sent by the controlled end, the communication channel from the controlled end to the main control end is communicated. If both sides can successfully receive the test file sent by the other side, the communication channel between the master control end and the controlled end is communicated.
Through the connectivity test, the connectivity between the master control end and the controlled end can be ensured, and the failure of data exchange caused by the connectivity problem between the master control end and the controlled end is avoided.
Optionally, the method of the embodiment of the present invention further includes: and monitoring the running state of the server and the file transmission state, and storing the monitored data. In this example, the master control monitors the running state and the file transmission state of the master control server, and stores the monitored data. By monitoring and storing the monitored data, the progress and the state of electronic data exchange can be known conveniently in real time, and faults can be found and fault reasons can be located conveniently in time when the faults occur.
Optionally, the method of the embodiment of the present invention further includes at least one of: and visually displaying the running state and the file transmission state of the server, visually displaying the server state and the file transmission state of the controlled end, and configuring a control command through a visual page. Through visual display, the running state and the file transmission state of the server of the master control end or the controlled end can be conveniently and visually known, and a control instruction can be conveniently configured.
Optionally, exchanging electronic data with the controlled end based on the data transmission protocol includes: scanning a sending directory, and if a file to be sent exists, sending the file to be sent to the controlled terminal through the data transmission protocol; and monitoring whether a file to be received sent by the controlled end based on the data transmission protocol exists, and if so, storing the file to be received in a receiving directory. In the actual application process, the master control end can confirm whether a file to be received sent by the controlled end based on the configured data transmission protocol exists or not by monitoring the port of the master control end. The method for sending and receiving the monitoring file is simple and efficient.
According to a second aspect of the embodiments of the present invention, there is provided a method for electronic data exchange, applied to a client, including: sending a heartbeat request to a main control terminal, wherein the heartbeat request comprises a server IP and a port number; after the main control terminal establishes connection according to the IP and the port number, receiving a control instruction sent by the main control terminal, and configuring protocol information according to the control instruction; the protocol information includes: a data transfer protocol for exchanging electronic data; and exchanging electronic data with the main control terminal based on the data transmission protocol. The method of electronic data exchange in the present embodiment is applied to the controlled side.
In this example, the data transmission protocols of the controlled end and the master control end are both configured by the master control end, and the master control end and the controlled end exchange electronic data based on the data transmission protocols. The specific type of the data Protocol may be selectively set according to actual situations, for example, FTP (File Transfer Protocol), OFTP2 (odd File Transfer Protocol Version 2, a Transfer Protocol proposed by the odd organization for transferring EDI messages), and the like.
Compared with the prior art that both electronic data exchange sides need to support the same data transmission protocol, the electronic data exchange method and the electronic data exchange device can enable electronic data exchange to be carried out even if the communication protocols of the servers of the both electronic data exchange sides are different, and are high in safety.
In the actual application process, before receiving the control instruction sent by the main control end, the main control end may be authenticated. Authentication refers to identifying whether the master control end has the authority to send a control instruction to the controlled end. For example, the master control end is authenticated through a verification code or a login password. And if the authentication is passed, receiving a control instruction sent by the main control end. Through authentication, the security of data exchange between the master control end and the controlled end can be improved.
The controlled end may send a heartbeat request to the main control end every time the controlled end is started, or send a heartbeat request to the main control end in response to a user operation instruction. The slave may initiate a heartbeat request to the master at intervals to establish a long connection with the master. When the long connection is disconnected due to network abnormality and the like, the controlled end may try reconnection at intervals, and the reconnection time interval may be set artificially, for example, the reconnection time interval is doubled in sequence.
Optionally, the protocol information further includes: communicating the test information; after configuring the protocol information according to the control instruction, the method further comprises the following steps: and performing connectivity test based on the connectivity test information, and confirming that the test is passed.
For example, after receiving the control instruction sent by the master control end, the controlled end configures a data transmission protocol and connectivity test information of the controlled end according to the control instruction. After the configuration is completed, the controlled end sends a test file to the main control end, and if the main control end successfully receives the test file sent by the controlled end, the communication channel from the controlled end to the main control end is communicated. After the configuration is completed, the master control end also sends a test file to the controlled end, and if the controlled end successfully receives the test file sent by the master control end, the communication channel from the master control end to the controlled end is communicated. If both sides can successfully receive the test file sent by the other side, the communication channel between the master control end and the controlled end is communicated.
Through the connectivity test, the connectivity between the master control end and the controlled end can be ensured, and the failure of data exchange caused by the connectivity problem between the master control end and the controlled end is avoided.
Optionally, the method of the embodiment of the present invention further includes: and monitoring the running state of the server and the file transmission state, and storing the monitored data. In this example, the controlled end monitors the running state and the file transmission state of the controlled end server, and stores the monitored data.

FIG. 3 is a schematic diagram of an electronic data exchange system in an alternative embodiment of the present invention. The electronic data exchange system of the present invention is described below with reference to fig. 3. In the embodiment shown in fig. 3, the data transfer protocol is the OFTP2 protocol. The main control end is deployed in the intra-enterprise server cluster, and specifically includes six parts, that is, an OFTP2 service (i.e., the aforementioned first data exchange module), a control service (i.e., the aforementioned first control service module), a control client (i.e., the aforementioned control client module), a heartbeat service (i.e., the aforementioned heartbeat service module), a monitor (i.e., the aforementioned first monitoring module), and a Web controller (i.e., the aforementioned Web controller module); the controlled end is deployed in a server cluster of a trading partner, and comprises OFTP2 service (i.e. the aforementioned second data exchange module), control service (i.e. the aforementioned second control service module), heartbeat client, and monitor (i.e. the aforementioned second monitoring module).
The OFTP2 service exists in both the master side and the slave side, and functions are identical. The OFTP2 service is used to support the host or slave to send and receive files via the OFTP2 protocol, and includes two components, namely a main transmitter and a receiver. The sender scans the sending directory (each trading partner has a respective sub-directory under the main directory) at regular time, and if the file to be sent is sent out through the OFTP2 protocol; the receiver listens to the configured port, which may support SSL (Secure Sockets Layer) or non-SSL (SSL port is taken as an example in fig. 3), and once it listens to the file transmitted by the OFTP2 protocol, the file is placed in the receiving directory.
The control service exists at the master control end and the controlled end, and the functions are completely the same. The control service consists of a receiver and a controller, wherein the receiver listens for control commands of a control port (SSL or non-SSL can be supported) and transmits command information to the controller; the controller receives the command from the receiver and controls the behavior of the OFTP2 service, including the port configuration of the OFTP2 receiver, the IP and port configuration of the partner server, connectivity test, etc.
The control client is present in the master. The control client sends a control command (the protocol for sending the control command can be customized, for example, based on the TCP protocol) to the control service of the master control end or the control server of the slave end, and the authentication of the service password is required for sending the control command.
The heartbeat service exists in the master control end, and the heartbeat client end exists in the controlled end. When the controlled terminal is started, a long connection request is initiated to the heartbeat service of the main control terminal through the heartbeat client terminal, and a heartbeat request is initiated to the heartbeat service at intervals. After long connection is disconnected due to network abnormality and the like, the heartbeat client side tries reconnection at intervals, and reconnection time intervals are sequentially doubled. After receiving the heartbeat request, the heartbeat service of the master control end records information such as IP (Internet protocol), service name, link state and the like of the server of the controlled end. After the long connection is established, the controlled end actively disconnects the link, or the main control end does not receive the heartbeat request for a long time, and the main control end marks the server of the controlled end as a disconnected state.
The monitors are arranged at the master control end and the controlled end and are used for monitoring the running state of the server, the file transmission state and the like, and the interface data are recorded into the database. In order to reduce the operation and maintenance cost of the database of the controlled end, the controlled end adopts the database (such as HSQLDB and the like) which is applied to the same virtual machine to run with the controlled end.
The Web controller resides in the host. The Web control provides a graphical Web page to control the control service of the master control end and the controlled end application, the state of the server of the controlled end and the file transmission state of the master control end are displayed, and the file transmission information of the controlled end application is obtained and displayed through the control client.
The protocol information of the main control end and the controlled end is configured by the main control end, and the data transmission protocols of the two electronic data exchange sides can be controlled by the main control end, so that the electronic data exchange can be carried out even if the communication protocols of the servers of the two electronic data exchange sides are different, and the safety is high.
Optionally, the electronic data exchange system further comprises a load balancing module; the controlled terminal sends a heartbeat request to the main control terminal, and the heartbeat request comprises the following steps: the controlled terminal sends the heartbeat request based on a fixed domain name (VIP), and the load balancing module screens a target main control terminal corresponding to the controlled terminal from a plurality of main control terminals based on a Hash consistency algorithm and forwards the heartbeat request to the target main control terminal.
The embodiment supports the characteristics of breakpoint continuous transmission and the like, and can enable the same controlled end to be linked to the same main control end when the disconnection is reconnected as much as possible. Illustratively, the load balancing module of this embodiment may employ a consistent HASH (HASH) algorithm based on NGINX (an HTTP and reverse proxy server) to drop a fixed portion of requests onto the same host.
Further, to improve network reliability, multiple load balancing modules may be bound to each VIP (e.g., one load balancing module for each NGINX, multiple NGINX are used).
Optionally, the number of the fixed domain names is multiple, where at least one of the fixed domain names is a hot standby domain name. As shown in fig. 4, the VIP2 and the VIP3 are served externally, and the VIP1 is used as a hot standby. The controlled end corresponds to a plurality of VIPs through resolution by fixing the domain name, and as shown in the figure, the VIP1 provides service when the VIP2 and the VIP3 cannot provide service. This can improve the reliability of data exchange.
