Explain the technical architecture of Web Services
XML-based SOAP message : SOAP is based on the communication provided by the transmission network, selects an appropriate transmission protocol (HTTP), and then stores the data to be exchanged in an XML document, and realizes data exchange of heterogeneous applications through network transmission Features.
Service description (WSDL) : It is based on XML and is used to describe the details of service port access methods and usage protocols. It is usually used to assist in generating server and client code and configuration information. When the service does not interact with the server, the service consumer needs to know which functional characteristics of the service to be used in order to call the specific service.
Unified description, discovery, and integration (UDDI) : It is a protocol for publishing and searching Web services (service publishing and service discovery). Applications can use this protocol to find the target Web service at design or runtime. UDDI is an open directory. Service providers register and publish Web Services to this directory, and service consumers also use this directory to discover services that meet their needs.
Service process: It is a regular collection of services. By orderly collecting some services, some automated business processes can be realized to improve efficiency.
