How to return JSON from MVC WEB API Controller
提问by user1662812
I understand that WEB API uses content negotiation for Accept - Content-Type to return json or xml. This is not good enough and I need to be able pragmatically decide if I want to return json or xml.
我了解 WEB API 使用内容协商接受 - Content-Type 返回 json 或 xml。这还不够好，我需要能够务实地决定是要返回 json 还是 xml。
The internet is flooded with obsolete examples of using HttpResponseMessage<T>, which is no longer present in MVC 4.
互联网上充斥着过时的 using 示例，HttpResponseMessage<T>MVC 4 中不再存在这些示例。
tokenResponse response = new tokenResponse();
response.something = "gfhgfh";
if(json)
{
return Request.CreateResponse(HttpStatusCode.OK, response, "application/json");
}
else
{
return Request.CreateResponse(HttpStatusCode.OK, response, "application/xml");
}
How do I change the above code so that it works?
如何更改上面的代码以使其正常工作？

Try like this:
像这样尝试：
public HttpResponseMessage Get()
{
tokenResponse response = new tokenResponse();
response.something = "gfhgfh";
if(json)
{
return Request.CreateResponse(HttpStatusCode.OK, response, Configuration.Formatters.JsonFormatter);
}
else
{
return Request.CreateResponse(HttpStatusCode.OK, response, Configuration.Formatters.XmlFormatter);
}
}
or even better, to avoid cluttering your controller with such plumbing infrastructure code you could also write a custom media formatter and perform this test inside it.
或者甚至更好，为了避免使用此类管道基础设施代码使您的控制器混乱，您还可以编写自定义媒体格式化程序并在其中执行此测试。
