ASP.NET MVC get current host
提问by Shawn Mclean
How do I get the host without using Request? This code can be placed in a controller:
如何在不使用的情况下获得主机Request？此代码可以放在控制器中：
return String.Equals(this.Request.Url.Host, absoluteUri.Host, StringComparison.OrdinalIgnoreCase);
but I'm moving it out of a controller and need to find another way to replace this this.Request.Url.Host.
但我正在将它从控制器中移出，需要找到另一种方法来替换它this.Request.Url.Host。
My whole purpose is to have access to this method in a helper class:
我的全部目的是在帮助类中访问此方法：
Url.IsLocalUrl(returnUrl);
My helper method will look like this:
我的辅助方法将如下所示：
public static string GetLocalUrl(string url)
{
if(Url.IsLocalUrl()){
return url;
}
else{
return Action("Security", "Home");
}
}

Either use HttpContext.Current.Request, or inject an instance of HttpContextBaseinto whatever it is that needs this information. I would recommend option 2 because, you can then easily test this other component. Since HttpContextBase can be mocked/stubbed.
要么使用 HttpContext.Current.Request，要么将 的实例注入HttpContextBase到需要此信息的任何内容中。我会推荐选项 2，因为这样您就可以轻松测试其他组件。由于 HttpContextBase 可以被模拟/存根。

You can use this outside of a controller:
您可以在控制器之外使用它：
System.Web.HttpContext.Current.Request.Url
