How to Make ASP. net web api respond to JSON format by default

By default, WEB APIs use the request sent by the browser Header of the client to determine the returned format, as shown in red. The browser uses XML by default. Therefore, if we do not limit the Accept value of the Header, XML is returned by default. The data formats returned by the wen api server mainly include XML and JSON. Our idea is to directly remove the XML format from the server, so naturally we have to return the JSON format.

 

 

Solution:

In Application_Start of Global. asax. cs

Join

GlobalConfiguration. Configuration. Formatters. XmlFormatter. SupportedMediaTypes. Clear ();

 

Save and regenerate F5.

 

 

We can see that the Accept value in the red area remains unchanged, but the returned data has become a lovely JSON. OVER
