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.

推荐答案

事实上，你的控制器将反序列化的身体像：

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; } }
