ASP.NET MVC:如何可靠地获取当前请求的真实URL? [英] ASP.NET MVC: How to reliably get the real URL of the current request?

问题描述

现在我有一个在 http://127.0.0.1:8081/(它实际上在Azure计算模拟器中运行).浏览器位置栏中的端口号清楚地显示为8081.

Right now I have an MVC application running on http://127.0.0.1:8081/ (it is actually running in the Azure compute emulator). The browser location bar clearly says 8081 for the port number.

但是Request.Url和Request.RawUrl都给我 http://127.0.0.1:8082/.

我需要发送一封带有URL的电子邮件，因此我需要正确的主机名和端口号.如何可靠地获得实际的真实URL，并且没有这种意外的偏差?

I need to send an e-mail with a URL in it, so I need the correct hostname and port number. How do I get the actual, real URL reliably and without such unexpected deviation?

推荐答案

您可以使用Request.Headers["Host"];，它将为您提供具有正确端口号的主机名(或IP).然后，您可以重建URL.

You can use Request.Headers["Host"]; which will give you the host name (or IP) with the correct port number. Then you can reconstruct the URL.
