Request.Url

Uri 方法獲取 Protocal Host Port

 

			Uri uri = new Uri("https://www.mywebsite.com:80/pages/page1.aspx");
			string requested =$"{uri.Scheme}   {Uri.SchemeDelimiter}    { uri.Host}    { uri.Port}   {uri.AbsolutePath}";
			Console.WriteLine(requested);
			// 【uri.Scheme/Request.Url.Scheme】   https 
			// 【Uri.SchemeDelimiter/Request.Url.SchemeDelimiter】   ://  
			// 【uri.Host/Request.Url.Host】  www.mywebsite.com 
			// 【uri.Port/Request.Url.Port】  80
			// 【Request.Url.AbsolutePath】   /pages/page1.aspx


			string aut = UriPartial.Authority.ToString();
			Console.WriteLine(aut);

			string authority = uri.GetComponents(UriComponents.SchemeAndServer, UriFormat.Unescaped);			
			Console.WriteLine(authority);
			// 【Request.Url.GetComponents(UriComponents.SchemeAndServer, UriFormat.Unescaped)】 https://www.mywebsite.com:80  可以灵活选择所需元素

			string requested2 = $"{uri.GetLeftPart(UriPartial.Authority)}";
			Console.WriteLine(requested2);
			//【uri.GetLeftPart(UriPartial.Authority)】 https://www.mywebsite.com:80
