在WCF中以哪种格式发送消息

Question

Context

I am new to WCF .

I was reading an article about message contract and found that WCF is sending message using SOAP .

My doubt is, if we are enabled REST in WCF service , then will it still use SOAP format for exchanging data.

In WebGet and WebInvoke attribute[which are for REST ], we are mentioning the inputformat like JSON or XML .

Question

If messages are sent through SOAP , then why are those needed ?

If all message contracts are sent using SOAP format, then message contract should not work in case of webHttp binding.

Answer 1

The protocol format will depend on the binding you select. Here's a list of the different system provided bindings and the underlying protocol they use.

In WebGet and WebInvoke attribute[which are for REST], we are mentioning the inputformat like JSON or XML. If messages are sent through SOAP, then why are those needed.

If you use the WebHttpBinding which uses standard HTTP instead of SOAP then those attributes allow you to specify whether you want to format the requests using plain XML (not SOAP) or JSON.
