在Web Api控制器中使用重定向(找到HTTP 302) [英] Use Redirect in Web Api Controller (HTTP 302 Found)

问题描述

由于某种原因，我在尝试找出如何从控制器内部重定向(HTTP 302 Found)到绝对URL时遇到很多麻烦.

For some reason I am having lots of trouble trying to find out how to redirect (HTTP 302 Found) to an absolute URL from within a controller.

我已经尝试过了:

this.Redirect("/assets/images/avatars/profile.jpg");

但是我抛出了异常

抛出异常:System.dll中的'System.UriFormatException'

Exception thrown: 'System.UriFormatException' in System.dll

其他信息:无效的URI:无法确定URI的格式.

Additional information: Invalid URI: The format of the URI could not be determined.

我似乎在这里看不到其他所有答案.我正在使用Web API和MVC 5.

Every other answer I see on here doesn't seem to be available to me. I am using Web API and MVC 5.

推荐答案

对于Redirect，您需要发送有效 URI.对于您的情况，如果只想返回relative URI，则必须告诉它URI class:

With Redirect, you need to send a valid URI. In your case, if you want to return only the relative URI, you must tell it to URI class:

public IHttpActionResult Get()
{
    return Redirect(new Uri("/assets/images/avatars/profile.jpg", UriKind.Relative));
}
