URL重写在生产服务器上不起作用。 [英] URL Rewriting does not work on production server.
问题描述
大家好，
我创建了一个带URL重写的Web应用程序。它在localhost上运行得非常好。但是当上传到生产服务器时它停止了工作。
然后我读了一些IIS6中不支持无扩展URL的地方（或者IIS配置需要更改，为此我无法控制）。因此我把.aspx扩展。它开始工作（本地和生产服务器）。但现在在生产服务器CSS& JavaScript文件未加载但在localhost上正常工作。
我使用的是Global.asax&我自己的URL重写模块。
Global.asax文件代码：
Hi all,
I have created a web application with URL Rewriting. It''s working absolutely fine on localhost. But when uploaded to production Server it stopped working.
Then I read some where that extentionless URLs are not suppoeted in IIS6 (or IIS configuration needs to be changed, and for that I have no control). Therefore I put .aspx extention. And it start working (both locally & on Production server). But now on Production server CSS & JavaScript Files are not loading but on localhost its working correctly.
I am using Global.asax & my own module for URL Rewriting.
Code on Global.asax file:
void Application_AcquireRequestState(object sender, EventArgs e)
{
//Session is Available here
string strLastURL = "";
string fullOrigionalpath = HttpContext.Current.Request.Url.ToString().ToLower();
if (fullOrigionalpath.Contains(".aspx") && !fullOrigionalpath.Contains("404error.aspx"))
{//Only .aspx files to be processed
if (HttpContext.Current != null && HttpContext.Current.Session != null)
{
if (HttpContext.Current.Session["LastAccessURL"] != null)
strLastURL = HttpContext.Current.Session["LastAccessURL"].ToString();
else
HttpContext.Current.Session["LastAccessURL"] = strLastURL = fullOrigionalpath;
}
if (fullOrigionalpath.Contains("/example.aspx") && fullOrigionalpath != strLastURL)
{
HttpContext.Current.Session["LastAccessURL"] = fullOrigionalpath;
HttpContext.Current.Response.Redirect("~/ChangedByUrl/Example.aspx");
}
try
{
HttpContext.Current.Session["LastAccessURL"] = fullOrigionalpath;
}
catch { }
}
}
重写模块代码：
Rewrite Module Code:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
/// <summary>
/// Summary description for RewriteURL
/// </summary>
public class RewriteURL : IHttpModule
{
public RewriteURL()
{
//
// TODO: Add constructor logic here
//
}
public void Init(HttpApplication application)
{
application.BeginRequest += (new EventHandler(this.Application_BeginRequest));
}
public void Dispose()
{
}
private void Application_Disposed(Object source, EventArgs e)
{
}
void Application_BeginRequest(object sender, EventArgs e)
{
string fullOrigionalpath = HttpContext.Current.Request.Url.ToString().ToLower();
if (fullOrigionalpath.EndsWith("/changedbyurl/example.aspx"))
{
HttpContext.Current.RewritePath("~/Example.aspx");
}
else if (fullOrigionalpath.Contains("/changedbyurl/"))
{
//This is to correctly load the CSS & Java scrit files or Images etc on page.
if (fullOrigionalpath.Contains("/changedbyurl"))
{
int start = 0;
int end = 0;
start = fullOrigionalpath.IndexOf("/changedbyurl");
end = start + "/changedbyurl".Length;
string strSubString = fullOrigionalpath.Substring(0, start);
strSubString += "~" + fullOrigionalpath.Substring(end);
fullOrigionalpath = strSubString;
}
string[] arr = fullOrigionalpath.Split('~');
if (arr.Length > 1)
{
HttpContext.Current.RewritePath("~/" + arr[arr.Length - 1]);
}
}
}
}

这对本地主机非常完美，但在生产（有IIS6）CSS& JavaScript文件未加载。
在head标签内的主页面上：
This working absolutely perfectly on local host but on production (having IIS6) CSS & JavaScript files are not loading.
On Master page inside head tag:
<link rel="stylesheet" href="jquery.megamenu.css" type="text/css" media="screen" />
<link href="style.css" rel="stylesheet" type="text/css" />
<link href="popup-div.css" rel="stylesheet" type="text/css" />
<link href="style1.css" rel="stylesheet" type="text/css" />
a bove CSS& Javascript文件在本地主机上正确加载，但在生产服务器上没有。我不想手动修复它们的路径作为绝对路径。我想知道为什么会这样？
后来添加-------------- --------
解决CSS&我使用以下方法的Javascript文件问题：
The above CSS & Javascript files are loading correctly on Local host but not on production server. I do not want to manually fix the paths for them as absolute path. I wonder why this is happening?
Added Later----------------------
To solve the CSS & Javascript files issue following approach is used by me:
protected void Page_Init(object sender, EventArgs e)
{
if (ViewState["OnceCalled"] != null)
return;
ViewState["OnceCalled"] = "Yes";
objUtility.SetCssVersion(Page);
}
private void SetCssVersion(Control objHead)
{
foreach (Control c in EnumerateControlsRecursive(objHead))
{
if (c is HtmlLink)
{
HtmlLink lnkStylesheet = (HtmlLink)c;
if (lnkStylesheet != null)
{
if (lnkStylesheet.Href.Contains("?"))
lnkStylesheet.Href += "&" + Version();
else
lnkStylesheet.Href += "?" + Version();
if (!lnkStylesheet.Href.ToLower().Contains(".com") || !lnkStylesheet.Href.ToLower().Contains("http:"))
{
lnkStylesheet.Href = "Website name here/" + lnkStylesheet.Href;
}
}
}
}
}
但仍未加载图片。
我不认为这种方法可以很好地使所有图像的URL绝对在页面上。
或者那里''处理这个问题的任何其他方法??
以后添加的结束----------------------
任何想法??
谢谢
Ashish
But still Images are not loading.
I don''t think this approach is good to make all image''s URL absolute on page.
Or there''s any other approach to handle this issue??
Added Later Ends----------------------
Any ideas??
Thanks
Ashish
推荐答案
但正在制作（拥有IIS6）CSS& JavaScript文件未加载
听起来好像是相对路径问题。有时，在部署之后，未正确形成作为图像，样式表等的源引用的路径。这导致在所引用的位置找不到文件，因为哪些图像无法下载或样式表未被应用。
您需要确保路径是正确的，例如文件找到并使用。
我建议您在设置文件来源之前使用此提示并正确解析路径：在多文件夹网站中解析路径 [ ^ ]
but on production (having IIS6) CSS & JavaScript files are not loading
Sounds like it is relative path issue. At times, after deployment the path referenced as a source for images, stylesheets, etc is not correctly formed. This leads to no file found at the location referred because of which images don''t download or style-sheets does not get applied.
You would need to make sure that the path is correct such that file is found and used.
I would suggest you to use this Tip and resolve the path correctly before setting the source of the file: Resolving Paths in a Multi-Folder WebSite[^]
