从MVC控制器返回JSON字符串 [英] return JSON string from MVC controller

问题描述

我用下面的code发送/接收对象到我的MVC控制器：

I use the following code to send/receive an object to my mvc controller:

$.ajax({
url: _createOrUpdateTimeRecord,
data: JSON.stringify(data),
type: "POST",
//dataType: "json",
contentType: "application/json; charset=utf-8",
beforeSend: function () {
    $("#loading-overlay").show();
},
success: function (data2) {
    try {   // tried to parse it manually to see if anything changes.
        data2 = JSON.parse(data2);
    }
    catch (err) {

    }
},
error: function (xhr, ajaxOptions, thrownError) {
    alert(thrownError + 'xhr error -- ' + xhr.status);
}

}）;

在我的MVC控制器我有我的JSON对象的字符串，所以我不需要.NET的JavaScriptSerializer和JsonResult。

On my mvc controller I have my JSON object as string so I don't need the .NET JavascriptSerializer and JsonResult.

我的JSON字符串如下：

My JSON string looks like:

data2 = "{title:'1111111',start:'2014-03-23T16:00:00.000',end:'2014-03-23T18:00:00.000',id:107,hdtid:1,color:'#c732bd',allDay:false,description:''}"

和我总是得到：
无效字符

And I always get: "Invalid character"

我已经尝试返回一个字符串，然后手动解析JSON的客户端。因此，我用ContentResult类型的返回类型，但没有成功。

I already tried to return a string and parse the JSON manually on client side. Therefore I used ContentResult as return type but with no success

    public class JsonStringResult : ContentResult
    {
        public JsonStringResult(string json)
        {
            Content = json;
            ContentType = "application/json";
        }
    }

这里有什么问题吗？该JSON看起来很好...

What is the problem here? The JSON looks fine...

干杯，

推荐答案

您DATA2是的无效 JSON字符串。它应该是：

Your data2 is INVALID JSON string. It should be:

data2 = "{\"title\":\"1111111\",\"start\":\"2014-03-23T16:00:00.000\",\"end\":\"2014-03-23T18:00:00.000\",\"id\":107,\"hdtid\":1,\"color\":\"#c732bd\",\"allDay\":false,\"description\":\"\"}"

在这里阅读JSON标准 http://json.org

JSON比普通的JavaScript更加严格，密钥必须用双引号和字符串在双引号被包裹得，单引号是无效的。

JSON is more strict than plain javascript, key has to be wrapped in double quote, and string has to be wrapped in double quote too, single quote is invalid.
