在返回的JSON双引号 [英] double quotes in returned json

问题描述

我有一个动作返回一个简单的JSON。出于演示的目的，我将粘贴示例code。简单的类序列化：

I have an action returning a simple json. For demonstration purposes I will paste sample code. Simple class to serialize:

public class Employee
{
    public string FullName { get; set; }
}

返回的JSON的操作：

The action which returns the json:

public JsonResult Test()
{
    var employee = new Employee { FullName = "Homer Simpson" };
    var serializer = new JavaScriptSerializer();
    var json = serializer.Serialize(employee);

    return Json(json, JsonRequestBehavior.AllowGet);
}

下面是我很困惑。当我打电话从浏览器这一行动，并期待在与小提琴手的反应，这是结果：

Here is where I am confused. When I call this action from the browser and look at the response with Fiddler, this is the result:

HTTP/1.1 200 OK
Server: ASP.NET Development Server/10.0.0.0
Date: Mon, 15 Aug 2011 20:52:34 GMT
X-AspNet-Version: 4.0.30319
X-AspNetMvc-Version: 3.0
Cache-Control: private
Content-Type: application/json; charset=utf-8
Content-Length: 34
Connection: Close

"{\"FullName\":\"Homer Simpson\"}"

在Fiddler中JSON标签上写着选定的响应不包含有效的JSON文本。
有效的反应应该是这样的：

The "JSON" tab in Fiddler reads "The selected response does not contain valid JSON text". The valid response should be like this:

"{"FullName":"Homer Simpson"}"

这是怎么回事？
谢谢

What is going on here? Thanks

推荐答案

您不需要序列化为JSON自己，这应该做的：

You don't need to serialize into JSON yourself, this should do:

public JsonResult Test() {
  var employee = new Employee { FullName = "Homer Simpson" };
  return Json(employee, JsonRequestBehavior.AllowGet);
}

您code有效连载了两次，它给你一个字符串结果。

Your code effectively serializes it twice, which gives you a string result.

有效的反应实际上应该是这样的：

The valid response should actually be this:

{"FullName":"Homer Simpson"}

（不带引号周围）
