Detailed Description
The invention is described in further detail below with reference to the figures and specific embodiments.
Aiming at the field of industrial robots, the invention designs a simplified SOAP protocol (Robot-SOAP protocol, RSOAP protocol for short), which not only simplifies body data of the original SOAP protocol, but also removes protocol header information in the original SOAP protocol, and greatly simplifies data volume of the original SOAP message. The RSOAP message referred to hereinafter is a simplified message body transmitted by using RSOAP protocol, that is, a message obtained by simplifying a request header and a request body of a SOAP message. In the RSOAP protocol, the method and the parameter information of the Webservice are not defined in an XML mode, but are transmitted in a very simple mode. By simplifying the request header and the request body, the data volume of the original SOAP message can be effectively compressed, the network transmission delay is reduced, and the service processing efficiency is improved.
Referring to fig. 2, the system for simplifying the SOAP message on the service bus in this embodiment includes a client, a service bus, and a server, where the client is connected to the server through the service bus, the server is deployed with a Webservice and an agent, the Webservice is connected to the agent, and the agent is connected to the service bus.
The client calls the client that has registered the Webservice service on the service bus. The service bus is a service bus for managing Webservice, and supports the receiving and parsing of RSOAP messages. The agent program is used for receiving the RSOAP request, analyzing the RSOAP message, packaging the analyzed message into SOAP message and transmitting the SOAP message to WebService.
Referring to fig. 3, the method for simplifying SOAP messages on a service bus according to the embodiment includes the following steps:
step (1), deploying WebService at a service end, wherein the WebService monitoring port monitors a SOAP request, and the WebService comprises a plurality of functions responding to the SOAP request;
step (2), deploying an agent program at the service end, and monitoring the RSOAP request by an agent program monitoring port;
registering an agent program and WebService with a service bus, specifically registering the agent program with the service bus according to an agent program IP address and a monitoring port, and registering the WebService with the service bus according to the WebService IP address and the monitoring port;
step (4), the client initiates an RSOAP request to the service bus, and specifically sends the RSOAP request to the service bus according to the designed RSOAP protocol message form;
step (5), after receiving the RSOAP request, the service bus forwards the RSOAP request to the service-side agent program, and specifically forwards the RSOAP request to the service-side agent program according to the registered agent program IP address and the monitoring port;
step (6), the server-side agent program receives the RSOAP request, analyzes the RSOAP message, encapsulates the analyzed message into an SOAP message, and forwards the encapsulated SOAP message to the server-side WebService through the WebService monitoring port;
and (7) the server WebService receives the SOAP message, analyzes the SAOP message, calls a function corresponding to the SAOP message according to the analyzed content, and executes corresponding function logic.
The server-side agent program is a server side of RSOAP protocol information, and can receive and analyze the RSOAP information, repackage the RSOAP information into SOAP information after analysis, and finally forward the SOAP information to the server-side Webservices. When the agent is started, two parameters are required to be specified, one is port (namely, the port number of the agent in operation cannot conflict with other programs), and the other is bindaddressor (namely, the service address of the agent is required, and the service address is a local address, such as http://127.0.0.1: 7001/Carry). After the server-side agent is started, the agent listens to the designated port and receives messages from the port.
The agent program runs as follows:
the method comprises the following steps: starting an agent program, and appointing a port and a service address needing agent;
step two: the agent receives the simplified RSOAP message;
step three: and analyzing the RSOAP message. Analyzing the RSOAP message according to the definition of the message in the RSOAP protocol, and repackaging the message into a SOAP message;
step four: and forwarding the encapsulated SOAP message to local Webservice.
In this way, the messages transmitted in the network are simplified RSOAP messages, greatly compressing the amount of data transmitted. And the SOAP message transmission is locally repackaged at the server side, the network transmission is not involved, and the transmission speed is high.
In order to compare the data volumes of the original SOAP protocol and the simplified RSOAP protocol, the following is a sample. In the sample, a carry method of the issued Webservice needs to be called, and only one parameter of the carry method is the stock number.
The following is a sample SOAP message:
a request head:
Figure BDA0003308180080000071
a request body:
Figure BDA0003308180080000072
Figure BDA0003308180080000081
the following is a sample of a simplified RSOAP message:
a request body:
rsoap://www.hnu.edu.cn:8001carry
stockNumber＝1
as can be seen from the above example, the SOAP message includes a request header and a request body, the request body is defined by XML, and redundant information exists in the open tag and the closed tag. In the simplified RSOAP message, however, the request header is removed and a portion of the data volume is compressed. Meanwhile, the simplified RSOAP message also adopts a very simple mode to transmit the name and the parameter information of the method, and the open label and the closed label are removed. In terms of the amount of data to be transmitted, the original SOAP message data amount is 47, the simplified RSOAP message data amount is 527, and the simplification proportion reaches 90%.
When the client requests the bus, the simplified RSOAP protocol is used, and when the bus requests the agent program, the simplified RSOAP protocol is also used, so that the simplified protocol is used in the network transmission, and the information quantity transmitted by the network is compressed. The proxy program forwards the service Webservice to use the SOAP message, but the transmission is carried out locally and does not involve network transmission. The invention can obviously reduce the data volume of Webservice message transmission, improve the processing efficiency of the service bus of the industrial robot and reduce the response time of the service bus of the industrial robot.
Various modifications and variations of the present invention may be made by those skilled in the art, and they are also within the scope of the present invention provided they are within the scope of the claims of the present invention and their equivalents.
What is not described in detail in the specification is prior art that is well known to those skilled in the art.
