帖子数组作为JSON到MVC控制器 [英] Post Array as JSON to MVC Controller

问题描述

我一直在努力找到解决这个问题。

I have been struggling to find a solution to this problem.

在我的code，我建立了一个对象的数组;

In my code, I am building up an array of an object;

var $marks = [];

var mark = function ( x, y, counter ){
    this.x = x;
    this.y = y;
    this.counter = counter;
}

$marks.push(new mark(1, 2, 0));   
$marks.push(new mark(1, 2, 1));
$marks.push(new mark(1, 2, 2));

现在我想张贴此数据到MVC控制器，所以我认为，在控制器中的数据类型将是列表与LT;马克和GT;标记或标记的数组。

Now I want to post this data to a MVC controller, so I would think that the data type in the controller would be a List<Mark> Marks or an array of Marks.

要发布的数据，我都试过;

To post the data, I have tried;

var json = JSON.stringify($marks);
$.post('url', json).done(function(data){ /* handle */ });

或

var json = { Marks: $marks };
$.post('url', json).done(function(data){ /* handle */ });

第二条路，看着公布数据时，看起来像这样

The second way, when looking at the data posted, looks like this

Marks[0][x]: 1
Marks[0][y]: 2
Marks[0][counter]: 0
Marks[0][x]: 1
Marks[0][y]: 2
Marks[0][counter]: 1
Marks[0][x]: 1
Marks[0][y]: 2
Marks[0][counter]: 2

但我不知道如何在控制器转换成一个强类型的对象呢？

But I am not sure how to translate this into a strongly typed object in the controller?

我的控制器看起来像这样;

My Controller looks like this;

[HttpPost]
public ActionResult JsonSaveMarks(List<Mark> Marks){
    // handle here
}

我的马类看起来是这样的;

My Mark class looks like this;

public class Mark{
     public string x { get; set; }
     public string y { get; set; }
     public string counter { get; set; }
}

我已经通过其他类似的问题有关创建自定义<读href=\"http://stackoverflow.com/questions/320291/how-to-post-an-array-of-complex-objects-with-json-jquery-to-asp-net-mvc-control\">JsonFilterAttribute,或者使用System.Web.Script.Serialization.JavaScriptSerializer一流的，但我不能得到任何工作。

I have read through other similar problems about creating a custom JsonFilterAttribute, or using the System.Web.Script.Serialization.JavaScriptSerializer class, but I cant get anything to work

有什么明显的，我在这里丢失？有我在控制器完全错误的数据类型？我怎么能转换成该数据发布到一个强类型的对象？

Is there something obvious I am missing here? Have I got the DataType in the controller completely wrong? How can I convert this data posted into a strongly typed object?

非常感谢

推荐答案

$后（）不允许您设置您的AJAX调用的内容类型 - 你可能会发现（如果你使用Fiddler），你的JSON字符串正在与内容类型发送应用程序/ x-WWW的形式urlen codeD（默认设置），然后导致Asp.Net MVC以正确跨preT的数据包。

$.post() doesn't allow you to set the content type of your AJAX call - you might find (if you use Fiddler) that your Json string is being sent with a content-type of "application/x-www-form-urlencoded" (the default setting) which then causes Asp.Net MVC to incorrectly interpret your data packet.

您可以尝试使用 $。阿贾克斯（）代替，并设置内容类型为application / JSON？

Can you try using $.ajax() instead, and set the content type to "application/json"?
