如何发布表单数据API控制器

本文介绍了如何发布表单数据API控制器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

表单数据发布使用jQuery：

Form data is posted using jquery:

$.ajax('API/Validate/Customer?column=1&rowid=2&vmnr=3&isik=4',
   {
       data: JSON.stringify({
           headerData: $("#_form").serializeArray()
       }),
       async: false,
       contentType: "application/json; charset=utf-8",
       dataType: "json",
       type: "POST"
   });

这是由ASP.NET MVC4的Web API控制器收到的验证：

It is received by ASP.NET MVC4 Web API controller Validate:

public class ValidateController : ApiController
{
    public class Body
    {
        public Dictionary<string, string> headerData { get; set; }
        public Dictionary<string, string> rowData { get; set; }
    }

    public HttpResponseMessage Validate(
        string id,
        string column,
        string rowid,
        int? vmnr,
        string isik,
        [FromBody] Body body,

        string dok = null,
        string culture = null,
        uint? company = null
       )
    { ...

body.headerData值为null控制器中。

body.headerData value is null in controller.

据回答
How以接收网络API控制器Post方法动态数据

body.headerData必须有形式键。
然而，它是空的。

body.headerData must have form keys.However, it is empty.

如何获得headerData在控制器键，值对的？

How to get headerData as key, value pairs in controller ?

Chorme开发工具显示正确的JSON是贴在身上：

Chorme developer tools show that proper json is posted in body:

{"headerData":[{"name":"Kalktoode","value":"kllöklö"},
               {"name":"Kaal","value":""}
              ]}

我试图删除

 public Dictionary<string, string> rowData { get; set; }

从类，但问题仍然存在。

from class but problem persists.

Your controller do not match with what you are sending

Indeed, your controller will deserialize body like:

{
  "headerData": {"someKey":"someValue", "otherKEy":"otherValue"},
  "rowData": {"someKey":"someKey"}
}

和它的不可以的你实际发送JSON的结构。
您的控制器寻找一个机构，2个成员 beeing的 Dictionnaries 的，不是的键值对的数组的

And it is not the structure of the JSON you actually send.Your controller looks for a body with 2 members beeing Dictionnaries, not Arrays of key value pair.

通过键值阵，我的意思是这样的：

By array of key value, I mean something like:

{
  "headerData": [
    {
      "key": "string",
      "value": "string"
    }
  ],
  "rowData": [
    {
      "key": "string",
      "value": "string"
    }
  ]
}

您需要更新您的身体对象：

You need to update your Body object to:

  [HttpPost, Route("test")]
  public void Test(Body b)
  {
  }

  public class Body
  {
      public List<KeyValuePair<string,string>> headerData { get; set; }
      public List<KeyValuePair<string,string>> rowData { get; set; }
  }
