如何在控制器中访问POST请求的参数

Question

Javascript:

$.post("/DataAPI/messageProcessor", { query: "Hello World!" }, function (data) {
  Handle(data); 
}
});

Controller:

[System.Web.Http.AcceptVerbs("Post")]
[System.Web.Http.ActionName("messageProcessor")]
public ResponseModel messageProcessor(string query)
{
  ResponseModel model=DoStuff(query);
  return model;
}

How do I access query from the controller. It always arrives as query == null . There is Request object available too but I am not sure how to navigate through its members to reach my "Hellow World!" .

Answer 1

You need to pass name-value pairs from the client:

$.post("/DataAPI/messageProcessor"
          , { query: "Hello World!" }
          , function (data) {} );

Check jQuery.Post for more details.

Answer 2

try this :

$.post("/DataAPI/messageProcessor", { 'query' : 'Hello World!' }, function (data) {
     Handle(data); 
   }
});

Thanks to a coworker. Solution is as following:

public class QueryClass 
{
public string query { get; set; }
}

public ResponseModel messageProcessor(QueryClass query)
{
  ResponseModel model=DoStuff(query.query);
  return model;
}
