ProgramFor. net, Web Service is actually a server class. A method of this class is marked in a special way so that. Net can know which methods are published on the service. Readers can use the following simple program to learn more about the internal mechanism of Web Service

The WEB service platform uses XSD as the data type system. When you use a language such as VB. NET or C # to construct a Web

Android applications usually run on mobile platforms. The hardware resources of mobile systems are far inferior to those of PC platforms. Whether it is storage or computing, it is possible to run some small applications on Android platforms, however, for a large amount of data processing, complex computing can only be deployed on remote servers, while Android applications can only act as c

The former is completed using a certain form of serialization engine (or called the mail collector), and the latter is completed through some form of metadata. For example, for most (modern) DCOM interfaces, the serialization engine is a type library blocker, while the Type Library provides metadata. The main difference between ASP. NET

programmers are familiar with DCOM or CORBA. SOAP also supports Document-style applications (SOAP messages contain only XML text information). Document-style applications have great flexibility, so many Web service that is difficult to build with RPC is built in this way.The final
httpsessionstate object, even the two processes run at the same time. If you want to process concurrent web service calls from the same process, these requests will be sorted on the server, so that only one request is executed at a certain time. The Web Service of Asp.net is not as common. the ASPX page supports read-
remoting to create a web service? The answer is yes and no. The standard Web Service technology stack depends not only on soap-based messages, but also on the description of messages based on WSDL and XSD. The remoting pipeline can truly generate the WSDL definition that de
workarounds include writing managed or unmanaged wrappers that provide a compatible interface that can be published as a WEB service. In most cases, writing such a wrapper is much less work than rewriting the entire component. This minimizes the development and testing effort required to apply existing applications as XML Web Services.
When you use unmanaged (Vi
access endpoints, each access entry uses a port element for description.
Port describes the deployment details of a service access portal, including the web address (URL) used for access and the message call mode used for access. The message call mode is represented by the binding structure.
The binding structure defines that a porttype is bound to a specific network transmission protocol or message tra

From the above technical level, we see that the first goal of Web service pursuit is simplicity. Perhaps people will find it very strange, there are so many agreements, how can you say that

I. Definition of WebServiceThere are several definitions of webservice:
The organization defines it: WebService is a software system designed to support cross-network interoperability between machines.
WebService is typically defined as a set of modular APIs that we can invoke over the network to run the remote system's request service.
WebService is a set of APIs exposed to external use that can be called through the
