"如何从 HttpContext (asp.net) 获取“主机：”标头"

Question

I need to server parts of my application from different domains. To be precise I have a sub section of the site that should be served from a region specific domain. For example:

Answer 1

string requestedDomain = HttpContext.Current.Request.ServerVariables["HTTP_HOST"];
string requestScheme = HttpContext.Current.Request.Url.Scheme;
string requestQueryString = HttpContext.Current.Request.ServerVariables["QUERY_STRING"];
string requestUrl = HttpContext.Current.Request.ServerVariables["URL"];

Answer 2

HttpContext.Current.Request.Url.Host

Answer 3

我想你想要 Request.Headers["host"]

Answer 4

在某些情况下，您想从发送 de 请求的主机那里知道，所以我使用了这个

 stsring _Host = HttpContext.Request.Headers["Referer"];
