The principle of WebService calling
realizes a complete web service workflow: The
web service provider designs and implements the web service, and publishes the debugged web service through the web service intermediary, and registers it in the UDDI registry;
The Web service requester requests a specific service from the Web service intermediary, and the intermediary queries the UDDI registry according to the request, and finds the service that satisfies the request for the requester;
The Web service intermediary returns the Web service description information that meets the conditions to the Web service requester. The description information is written in WSDL and can be read by all machines that support Web services;
Use the description information returned from the web service intermediary to generate the corresponding SOAP message and send it to the web service provider to implement the call of the web service;
The Web service provider executes the corresponding Web service according to the SOAP message, and returns the service result to the Web service requester.
