Web Service Learning

It was a shame to have not learned the content of Web service so long. Let's take a break today and learn a bit better.

concept of 1.Web service

The concept is only to replicate the content of the person.

Web service, also known as XML Web service WebService, is a lightweight, independent communication technology that can receive requests passed from the Internet or other systems on the intranet. is: Software services provided through SOAP on the web, described using WSDL files, and registered through UDDI.

XML: (extensible Markup Language) Extensible Markup Language. Temporary data processing for short-term, web-oriented network, is the basis of soap.

Soap: Simple Object access Protocol protocol. is the communication protocol for XML WEB Service. When a user finds your WSDL description document through UDDI, he can invoke one or more of the actions in the Web service that you set up by soap. SOAP is a specification for calling methods in the form of XML documents that can support different underlying interfaces, such as HTTP (S) or SMTP.

WSDL: (Web Services Description Language) A WSDL file is an XML document that describes a set of SOAP messages and how to exchange them. In most cases, it is automatically generated and used by the software.

UDDI (Universal Description, Discovery, and integration) is a new project primarily for Web service providers and users. Before a user can invoke a Web service, it is important to determine which business methods are included in the service, to find the called interface definition, and to prepare the software on the server side, and UDDI is a mechanism to guide the system through the description document to find the appropriate service. UDDI uses the SOAP message mechanism (standard xml/http) to publish, edit, browse, and find registration information. It uses XML format to encapsulate various types of data and send it to the registry or to the registry to return the required data.

Replication is fast, and then I have to spend a lot of time understanding it. Cond...
