生成没有端口号的绝对URL的解决方法 [英] Workaround for generating absolute URLs without port number

问题描述

大家好，



我的网站托管在appHarbor上。当我访问一个页面时，它附加一个端口号与引用的URL如：http：/ /www.test.com/test.aspx?returnUrl=http://www.test.com:11111/abc/kgh.aspx。

它附加了11111端口号。我在那里coundnt转到那个页面。



我有一个方法但无法理解和使用它：

  public   static   string  ToPublicUrl（此 UrlHelper urlHelper，Uri relativeUri）
 {
  var  httpContext = urlHelper.RequestContext.HttpContext; 
 
  var  uriBuilder =  new  UriBuilder 
 {
 Host = httpContext.Request.Url.Host，
 Path =   /，
 Port =  80 ，
 Scheme =   http，
}; 
 
  if （httpContext.Request.IsLocal）
 {
 uriBuilder.Port = httpContext.Request.Url.Port ; 
} 
 
  return   new  Uri（uriBuilder.Uri，relativeUri ）.AbsoluteUri; 
} 

任何人都可以帮助我...



谢谢

解决方案

你需要覆盖这个函数。

这是ToPublicURL的完整类





使用System;

使用System.Web;

使用System。 Web.Mvc;



名称空间MileageStats.Web.Helpers

{

公共静态类UrlExtensions

{

//偶尔，我们需要生成一个可公开访问的URL。

//例如，在使用第三个进行身份验证的情况下派对我们需要提供

//第三方调用的返回URL。

//在某些情况下，例如使用处理服务提供商托管应用程序

//通过在不同端口上内部转发请求来加载余额，标准

// ge的方法在ASP.NET中编写URL可以使用其中一个内部端口。

// ToPublicUrl帮助我们创建一个可公开访问的URL。

公共静态字符串ToPublicUrl （这个UrlHelper urlHelper，字符串动作，字符串控制器）

{

var uri = new Uri（urlHelper.Action（action，controller），UriKind.Relative）;

返回ToPublicUrl（urlHelper，uri）;

}



公共静态字符串ToPublicUrl（此UrlHelper urlHelper，Uri relativeUri ）

{

var request = urlHelper.RequestContext.HttpContext.Request;

返回ToPublicUrl（request，relativeUri）;

}



公共静态字符串ToPublicUrl（此HttpRequestBase请求，Uri relativeUri）

{

var url = request.Url;

返回ToPublicUrl（url.Host，u rl.Scheme，url.Port，request.IsLocal，relativeUri）;

}



公共静态字符串ToPublicUrl（此HttpRequest请求，Uri relativeUri）

}



//注意：这假设在不在本地运行时将始终使用端口80。 br />
私有静态字符串ToPublicUrl（字符串主机，字符串方案，int端口，bool isLocal，Uri relativeUri）

{

var uriBuilder = new UriBuilder

{

主机=主机，

路径=/，

端口= 80，

Scheme = scheme，

};



if（isLocal）

{

uriBuild er.Port = port;

}



返回新的Uri（uriBuilder.Uri，relativeUri）.AbsoluteUri;

}



公共静态字符串UnencodedAction（此UrlHelper助手，字符串操作，字符串控制器，对象routeValues）

{

返回HttpUtility.UrlDecode（helper.Action（action，controller，routeValues））;

Hello All,

My Website is hosted on appHarbor.When I access a page it is appending a port no with the referred Url like:"http://www.test.com/test.aspx?returnUrl=http://www.test.com:11111/abc/kgh.aspx".
It is appending 11111 port no.There by I coundnt go to that page .

I have got a method but unable to understand and use it:

public static string ToPublicUrl(this UrlHelper urlHelper, Uri relativeUri)
   {
       var httpContext = urlHelper.RequestContext.HttpContext;

       var uriBuilder = new UriBuilder
       {
           Host = httpContext.Request.Url.Host,
           Path = "/",
           Port = 80,
           Scheme = "http",
       };

       if (httpContext.Request.IsLocal)
       {
           uriBuilder.Port = httpContext.Request.Url.Port;
       }

       return new Uri(uriBuilder.Uri, relativeUri).AbsoluteUri;
   }

Can anybody help me...

Thanks

解决方案

You need to override this function.
Here is the complete class for ToPublicURL


using System;
using System.Web;
using System.Web.Mvc;

namespace MileageStats.Web.Helpers
{
public static class UrlExtensions
{
// Occasionally, we need to generate a url that is publicly accessible.
// For example, in the case of authenticating with a third party we need to provide
// a return url for the third-party invoke.
// In some circumstances, such as hosting the app with a service provider that handles
// load balances by forwarding the request internally on different ports, the standard
// approach for generating a URL in ASP.NET may use one of the internal ports.
// ToPublicUrl helps us a create a URL that will be publically accessible.
public static string ToPublicUrl(this UrlHelper urlHelper, string action, string controller)
{
var uri = new Uri(urlHelper.Action(action, controller), UriKind.Relative);
return ToPublicUrl(urlHelper, uri);
}

public static string ToPublicUrl(this UrlHelper urlHelper, Uri relativeUri)
{
var request = urlHelper.RequestContext.HttpContext.Request;
return ToPublicUrl(request,relativeUri);
}

public static string ToPublicUrl(this HttpRequestBase request, Uri relativeUri)
{
var url = request.Url;
return ToPublicUrl(url.Host,url.Scheme,url.Port,request.IsLocal, relativeUri);
}

public static string ToPublicUrl(this HttpRequest request, Uri relativeUri)
{
var url = request.Url;
return ToPublicUrl(url.Host, url.Scheme, url.Port, request.IsLocal, relativeUri);
}

//Note: this assumeS that port 80 will always be used when not running locally.
private static string ToPublicUrl(string host, string scheme, int port, bool isLocal, Uri relativeUri)
{
var uriBuilder = new UriBuilder
{
Host = host,
Path = "/",
Port = 80,
Scheme = scheme,
};

if (isLocal)
{
uriBuilder.Port = port;
}

return new Uri(uriBuilder.Uri, relativeUri).AbsoluteUri;
}

public static string UnencodedAction(this UrlHelper helper, string action, string controller, object routeValues)
{
return HttpUtility.UrlDecode(helper.Action(action, controller, routeValues));
}
}
}
