JSON解析的阵列中的ASP.Net对象 [英] Parse Array of JSON Objects in ASP.Net

问题描述

我想学ASP.Net MVC，我想张贴JSON对象到服务器的阵列和发回给客户端。一切都很好，当我使用<一个href=\"https://chrome.google.com/webstore/detail/postman-rest-client/fdmmgilgnpjigdojojpjoooidkmcomcm?hl=en\"相对=nofollow>邮差，但它并没有实际网页上工作。我认为这个问题是不是与jQuery code的职位数组或ASP.Net code，是不是能够解析数组。

I am trying to learn ASP.Net MVC and I wanted to post array of JSON objects to the server and sent it back to the client side. Everything is fine when I use Postman, but it doesn't work on actual web page. I think the problem is either with jQuery code that posts the array or ASP.Net code that is not able to parse the array.

下面是我的控制器code：

Here is my controller code:

[System.Web.Mvc.HttpPost]
public ActionResult GetResult(List<Table> list)
{
    return Json(list);
}

下面是我的对象声明：

public class Table
{
    public int Id { get; set; }
    public String Question { get; set; }
    public int Answer { get; set; }
}

下面是jQuery的code，它的帖子中的数据：

Here is jQuery code that posts the data:

$.post("./GetResult", JSON.stringify(tableData), function (data, status) { alert(status); }, "json");

和资料表是JSON像这样的数组：

and tableData is an Array of JSON like this:

[
    {
        "Id": 500,
        "Question": "where are you from",
        "Answer": 2
    },
    {
        "Id": 501,
        "Question": "how old are you",
        "Answer": 1
    },
    {
        "Id": 502,
        "Question": "what is your first car",
        "Answer": 2
    },
    {
        "Id": 503,
        "Question": "do you have kids",
        "Answer": 1
    }
]

另外，我可以看到我的code穿过后控制器，但它是空的或为null。

Also, I can see that my code goes through the post controller but it is empty or null.

这里是我CSHTML文件的链接。

推荐答案

试着在你的请求，指定内容类型：

Try to specify content-type in your request:

$.ajax({
  url: "./GetResult",
  type: "POST",
  data: JSON.stringify(tableData),
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function (data, status) { alert(status); }
})
