如何在ASP.NET Core中将403禁止响应作为IActionResult返回

问题描述

当我尝试执行无效操作时，我想向客户端返回403 Forbidden.我需要使用什么方法?

I would like to return a 403 Forbidden to the client when trying to perform an invalid operation. What is the method I need to use?

我在Internet上进行了搜索，但仅在MVC 5中找到了这些内容:

I searched over the internet but I found only these for MVC 5:

return Request.CreateErrorResponse(HttpStatusCode.Forbidden, "RFID is disabled for this site.");
Or  if the return type for your web api method is IHttpActionResult then you need to use the below code

return StatusCode(HttpStatusCode.Forbidden,"RFID is disabled for this site.");

如何为IActionResult类型返回403:

How to return 403 for IActionResult type:

public IActionResult Put(string userid, [FromBody]Setting setting)
 {
    var result = _SettingsRepository.Update(userid, setting);
    if (result == true)
    {
       return Ok(201);
    }
    else
    {
       return BadRequest();
    }
 }

推荐答案

当您要使用HTTP 403状态和 allow 进行响应时，ASP.NET Core的身份验证逻辑将使用其禁止的处理方式来处理响应逻辑(可以在您的Startup类中进行配置，并且可能导致重定向到另一个页面)，请使用:

When you want to respond with a HTTP 403 status and allow ASP.NET Core's authentication logic to handle the response with its forbidden handling logic (can be configured in your Startup class, and may cause a redirect to another page), use:

return Forbid();

(与Unauthorized()相同)

当您要使用来自API的HTTP 403状态代码响应并且不希望 ASP.NET Core身份验证逻辑执行任何重定向或其他操作时，请使用:

When you want to respond with a HTTP 403 status code from an API and do not want the ASP.NET Core authentication logic to perform any redirect or other action, use:

return StatusCode(403);
