相同方法.NET Core Web API上的多种类型[FromBody] [英] Multiple types [FromBody] on same method .net core web api

问题描述

我有一个带有POST方法的控制器，它将接收一个xml字符串，该字符串可以是2种类型。例如：

I have a controller with one POST method, which will receive an xml string which can be of 2 types. Eg:

[HttpPost("postObj")]
    public async Task<IActionResult> postObj([FromBody]firstClass data)
    {
        if (data != null)...

我希望能够绑定到同一条路由上的多种类型（[HttpPost（ postObj）]）
这样我就可以在 http://127.0.0.1:5000/api/postObj 在主体中包含firstClass xml，在主体中包含secondClass xml，并采取相应的措施。

I would like to be able to bind to multiple types on the same route ([HttpPost("postObj")]) So that I can receive on http://127.0.0.1:5000/api/postObj with firstClass xml in the body, or secondClass xml in the body, and act accordingly.

我尝试制作另一种具有相同路线但类型不同的方法，例如：

I tried making another method with the same route but different type like:

    [HttpPost("postObj")]
    public async Task<IActionResult> postObj([FromBody]secondClass data)
    {
        if (data != null)...

但是我得到的是请求匹配多个动作导致歧义，正如预期的那样。

but I get "Request matched multiple actions resulting in ambiguity", as expected.

我尝试读取正文并进行检查然后序列化xml

I tried reading the body and doing a check then serializing the xml to the respective object, but that drastically reduced the performance.

我期望每秒最多100个请求，并且使用FromBody进行绑定可以使我得到，但是手动读取正文和序列化仅给我约15。

I am expecting up to 100 requests per second, and binding using FromBody is giving me that, but manually reading the body and serializing gives me only about 15.

如何实现？

推荐答案

您不能用相同的路线定义两个动作。动作选择器不考虑其参数类型。因此，为什么不合并此操作；

You can't define two actions with same route. Action Selector doesn't consider their parameter types. So, why don't you merge this actions;

public async Task<IActionResult> postObj([FromBody]EntireData data)
{
    if (data.FirstClass != null)
    {
        //Do something
    }
    if (data.SecondClass != null)
    {
        //Do something
    }
}

public class EntireData
{
    public FirstClass  firstClass { get; set; }

    public SecondClass secondClass { get; set; }
}
