如何从ASP.NET Core RC2 Web Api返回HTTP 500? [英] How to return HTTP 500 from ASP.NET Core RC2 Web Api?

问题描述

回到RC1，我会这样做:

Back in RC1, I would do this:

[HttpPost]
public IActionResult Post([FromBody]string something)
{    
    try{
        // ...
    }
    catch(Exception e)
    {
         return new HttpStatusCodeResult((int)HttpStatusCode.InternalServerError);
    }
}

在RC2中，不再有HttpStatusCodeResult，而且找不到让我返回500类型的IActionResult的任何东西.

In RC2, there no longer is HttpStatusCodeResult, and there is nothing I can find that lets me return a 500 type of IActionResult.

对于我要问的问题，现在的方法是否完全不同?我们是否不再尝试在Controller代码中捕获?我们是否只是让框架向API调用者抛出泛型500异常?对于开发，如何查看确切的异常堆栈?

Is the approach now entirely different for what I'm asking? Do we no longer try-catch in Controller code? Do we just let the framework throw a generic 500 exception back to the API caller? For development, how can I see the exact exception stack?

推荐答案

据我所见，ControllerBase类内部有帮助方法.只需使用StatusCode方法:

From what I can see there are helper methods inside the ControllerBase class. Just use the StatusCode method:

[HttpPost]
public IActionResult Post([FromBody] string something)
{    
    //...
    try
    {
        DoSomething();
    }
    catch(Exception e)
    {
         LogException(e);
         return StatusCode(500);
    }
}

您还可以使用StatusCode(int statusCode, object value)重载来协商内容.

You may also use the StatusCode(int statusCode, object value) overload which also negotiates the content.
