将多个对象发布到Web API [英] Post multiple objects to web API

问题描述

我正在尝试使用JSON对象将数据传递到我的Web API.发送单个对象似乎可以正常工作，但是一旦我输入了第二个参数，第二个对象似乎甚至无法在服务器端初始化?

I am trying to pass data to my web API using JSON objects. Sending a single object does seems to work fine but as soon as I put a second parameter, the second object does not even seems to initialize on the server side?

请查看下面的代码，以查看我如何处理数据参数

Please view the code below to see how I am handling the data parameter

[HttpPost("")]
public JsonResult Post([FromBody]Log_Header headerData, 
                       [FromBody]Log_Detail detailData)
{
    return Json("Test");
}

上面的每个类都有简单的字符串数据，例如下面的类:

Each of the classes above have simple string data, eg of class below:

public class Log_Header
{
    public int Id { get; set; }
    public string Name{ get; set; }
}

正在发送的数据示例:

var header = {
    Id: 0,
    Name: "Test 3",
}

var detail = {
    Id: 0,
    Desc: "Test 1",
}

$http({
    method: 'POST',
    url: "api/addLog",
    data : { 
        header: header,
        detail: detail
    }
})

这仅仅是演示数据.

我尝试过几种不同的方式发送数据，例如:

I have tried sending the data up in few different ways e.g below:

 var data = {
     Id: 0,
     Name: "Test 3",
     LogID: 0,
     Desc: "Test",
 }

但是似乎什么都无法正常工作，我猜我在错误地设置了Web API?

But nothing seems to get this working, I'm guessing I am setting up the web API incorrectly?

总体而言，问题是[FromBody]Release_Log_Detail detailData根本不接收任何数据，并且从断点查看对象时，它显示为null.

Overall, the problem is [FromBody]Release_Log_Detail detailData does not receive any data at all and when viewing the object from a breakpoint it appears as null.

如果有人有任何想法，请在下面发表评论或回答.如果您需要我的更多信息，请询问.

if anyone has any ideas please leave a comment or answer below. If you need anymore information from me please ask.

推荐答案

无论我们从angular $ http发布什么内容，它都会考虑单个对象，因此我们需要在服务器上的单个对象中读取它

Whatever we post from angular $http, it consider a single object, so we need to read it in a single object on server

我们可以这样做

[HttpPost("")]
public JsonResult Post([FromBody]PostData data)
{
    return Json("Test");
}

class PostData
{
   public Log_Header LogHeader { get; set; }
   public Log_Detail LogDetail { get; set; }

}

角柱

$http({
   method: 'POST',
   url: "api/addLog",
   data : { 
      LogHeader : header,
      LogDetail : detail
  }
})
