如何在API控制器操作中将复杂对象作为$ http参数传递并作为视图模型接收 [英] How to pass complex object as $http params and receive as a view model in API controller action

问题描述

我有一个API端点.控制器动作如下所示-

I have an API endpoint. The controller action looks like this -

public IHttpActionResult Post(string entityType, SomeModel someModel)

SomeModel是一个视图模型，看起来像这样-

Here SomeModel is a view model, which looks like this -

public class SomeModel
  {
    public long? Id { get; set; }
    public long EntityId { get; set; }
    public string Text { get; set; }
  }

我正在从angularjs end调用此API端点-

I am calling this API endpoint from angularjs end -

return $http({
            method: 'POST',
            url: ENV.apiEndpoint + 'tags',
            params:{
              // here I want to pass parameters which will automatically map into API's two parameter(one string and the other view model)
            }
        });

我不想更改我的API端点.我的问题是如何从有角度的末端传递参数，该参数会自动映射到API方法的参数中.

I don't want to alter my API endpoint. My question is how I can pass parameter from angular end, which will automatically map into the argument of API method.

我尝试了很多事情-

var someModel = {id: 1, text:"something", entityId: 12}
return $http({
            method: 'POST',
            url: ENV.apiEndpoint + 'tags',
            params:{
              entityType: entityType,
              someModel: JSON.stringify(someModel)
            }
        });

或者，

var someModel = {id: 1, text:"something"}
return $http({
            method: 'POST',
            url: ENV.apiEndpoint + 'tags',
            params:{
              entityType: entityType,
              id: 1,
              text: "something",
              entityId: 12
            }
        });

这些似乎都不起作用.意味着参数没有正确地映射到API方法的参数中.在这种情况下传递参数的理想方法是什么?

None of these seems to work. Meaning the params is not correctly getting mapped into the argument of API method. What is the ideal way to pass params in this type of scenario?

我不想更改API方法的参数.我知道我可以使用[FromBody] or [FromURI].但是我不想那样做.

I don't want to change my API method's argument. I know I can use [FromBody] or [FromURI]. But I don't want to do those.

推荐答案

您应该能够做到

    $http({
        method: 'POST',
        url: ENV.apiEndpoint + 'tags',
        params:{
          entityType: entityType
        },
        data: someModel
    });

默认情况下，POST请求中的默认Web api(和asp.net mvc)反序列化(引用)来自HTTP消息正文( data )的对象参数，以及来自URL参数( params ).

By default web api (and asp.net mvc) in a POST request deserializes (reference) object arguments from http message body (data) and value types and string arguments from URL parameters (params).
