将JSON从控制器反序列化为AJAX成功

Question

I am having trouble finding the right format of using a HttpWebRequest , and returning its response into readable JSON for a Javascript AJAX function.

If I return just text , it adds escaping slashes to the response. If I deserialize text it then add's all the indentation and makes it unreadable by my Javascript. (I think because it is not passing an actual object either)

Just trying to pass a readable json object to my ajax.

Controller

[HttpPost]
public ActionResult teamLookUp(string ID)
{
    HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("someurl.com/apis");
    myReq.ContentType = "application/json; charset=utf-8";
    var response = (HttpWebResponse)myReq.GetResponse();
    string text;

    using (var sr = new StreamReader(response.GetResponseStream()))
    {
        text = sr.ReadToEnd();
    }

    var json2 = JsonConvert.DeserializeObject(text);
    return Json(new { json = json2 });

    // return Json(new {json = text}); returns json with escaping \'s 
    //     i.e. "json":"{\"item":\"item2"}
    // return Json(new {json = json2}); returns empty json, 
    //     i.e. {"json":[[],[],[],[]]}
}

Javascript

 $.ajax({
        url: "/Competitive/teamLookUp",
        type: "POST",
        data: "ID=" + ID,
        success: function (json) {
            alert(JSON.stringify(json));
            alert(json[ID].name());
        }, 
        error: function(error) {
        }
   });

Need help with returning json object back to my AJAX success function.

Answer 1

use

dynamic json2=JsonConvert.DeserializeObject(text);

instead of

var json2 = JsonConvert.DeserializeObject(text);

hope that helps

Answer 2

What kind of object are you trying to deserialize the response into? Right now it is just going into a string. Might want to create a object to deserialize the response from the service you are calling.

Here is a working example to return a string object I came up with

    public ActionResult ReturnJson()
    {
        var someText = "some random text";

        return Json(new {json = someText});
    }

Javascript

<script>
    function testAjaxCall() {
        $.ajax({
           url: '@Url.Action("ReturnJson")',
           type: "POST",
           success: function (result) {
               alert(result);

               alert(result["json"]);
           },
           error: function (error) {}
        });

    }
</script>
