Let us discuss about SOAP In Android Training in Chandigarh : SOAP is very important concept in Android Training in Chandigarh. Let us Discuss it in Efficient way
SOAP : Introduction on SOAP
- SOAP is a protocol to transport data to and from the web-server.
- SOAP is simply XML Based protocol to let applications exchange information over HTTP. Or more simply ; SOAP is a protocol for accessing a web services.
- SOAP is used for communication between applications via the internet.
- SOAP is designed to be a new protocol for the decentralized , distributed environment, which utilises the power of the internet and XML to pass typed information between nodes.
- SOAP is forming a necessary base or core a stateless, One way message exchange paradigm between SOAP nodes, from a SOAP sender to a SOAP receiver. By combining One- way exchanges with features provided by the underlying transport protocol and/or application specific information, SOAP can be used to create more complex interactions such as request/response , request/multiple response, etc.
- SOAP is a lightweight protocol that is operating system independent,transport independent, platform independent, and, all because it is built by using time testing systems like the HTTP protocol and text markup in XML.
Types of SOAP Requests :
There are two types of SOAP Requests:
- Remote Procedure Call (RPC) Style Request : It is similar to other distributed architectures. This is usually synchronous; the client sends a message and waits to get a response or fault message back from the server.
- SOAP-RPC is an implementation of a remote procedure call (RPC). In this case, a function on a remote machine is called as if it were a local function. All of the marshalling and unmarshalling of data is handled by SOAP and is performed in XML.
- RPC- Style Web services are tightly coupled and interface-driven. The clients invoke the web services by sending parameters and receiving return values.
Document Style Requests: Another type of SOAP request is the document request. In this case, a full XML document is passed to/from the client and server, inside a SOAP message. With a document style message the client and/or server passes an XML document as the body of the SOAP message instead of parameters.
For Example: An invoice, the document is marked up with both XML, and a schema, which is common to both the sender and receiver. The sender is the consumer, which makes a function call to the web services with some parameters., not data results but an XML document that contains all of the information And in return the vendors sends back that a normal invoice would have, the difference being that it is marked up with XML, and is machine- readable.
