更改请求的 WebResource.axd url [英] Change the requested url of WebResource.axd
问题描述
我的网络应用程序 (http://www.something.com/social/competition/) 当前正在请求 WebResource.axd 文件,如下所示:
My web application (http://www.something.com/social/competition/) is currently requesting the WebResource.axd file like this:
<script src="/WebResource.axd?d=xxx" type="text/javascript"></script>
由于我们在 Netscaler 中使用 urlrewiting 将对/social"文件夹的所有请求转发到包含此应用程序的单独服务器场,因此/"根路径将无法正确解析,因为它将请求资源来自 something.com 应用.
As we're using urlrewiting in a Netscaler to forward all requests for the "/social" folder onto a seperate server farm containing this app, the "/" root path won't resolve correctly as it will be requesting the resource from the something.com app.
因此,我需要更改所请求脚本的 url 以明确请求它:
Therefore I need to change the url of the requested script to either request it explicitly:
<script src="/social/WebResource.axd?d=xxx" type="text/javascript"></script>
或使用相对路径请求它:
or to request it using a relative path:
<script src="WebResource.axd?d=xxx" type="text/javascript"></script>
到目前为止,我已经研究了覆盖渲染方法、使用控制适配器和其他各种东西,但到目前为止还没有真正实现.请帮忙.
So far I've looked at overriding the render method, using a control adapter and various other things but haven't really got anywhere as of yet. Help please.
推荐答案
是的,经过广泛研究后发现,实际上不可能覆盖这些文件的渲染过程.所以唯一的其他选择是肮脏、肮脏、可怕的黑客攻击!
Right, so it turns out after extensive research that it's practically impossible to override the rendering process for these files. So the only other option was a filthy, dirty, horrible hack!
protected void Page_Load(object sender, EventArgs e)
{
//Initialises my dirty hack to remove the leading slash from all web reference files.
Response.Filter = new WebResourceResponseFilter(Response.Filter);
}
public class WebResourceResponseFilter : Stream
{
private Stream baseStream;
public WebResourceResponseFilter(Stream responseStream)
{
if (responseStream == null)
throw new ArgumentNullException("ResponseStream");
baseStream = responseStream;
}
public override bool CanRead
{
get { return baseStream.CanRead; }
}
public override bool CanSeek
{
get { return baseStream.CanSeek; }
}
public override bool CanWrite
{
get { return baseStream.CanWrite; }
}
public override void Flush()
{
baseStream.Flush();
}
public override long Length
{
get { return baseStream.Length; }
}
public override long Position
{
get
{
return baseStream.Position;
}
set
{
baseStream.Position = value;
}
}
public override int Read(byte[] buffer, int offset, int count)
{
return baseStream.Read(buffer, offset, count);
}
public override long Seek(long offset, System.IO.SeekOrigin origin)
{
return baseStream.Seek(offset, origin);
}
public override void SetLength(long value)
{
baseStream.SetLength(value);
}
public override void Write(byte[] buffer, int offset, int count)
{
//Get text from response stream.
string originalText = System.Text.Encoding.UTF8.GetString(buffer, offset, count);
//Alter the text.
originalText = originalText.Replace("/WebResource.axd", "WebResource.axd");
//Write the altered text to the response stream.
buffer = System.Text.Encoding.UTF8.GetBytes(originalText);
this.baseStream.Write(buffer, 0, buffer.Length);
}
这会拦截到页面的流并将所有出现的/WebResource.axd"替换为WebResource.axd".由于它是一个相对路径,它解析得很好!
This intercepts the stream to the page and replaces all occurrences of "/WebResource.axd" with "WebResource.axd". As it's a relative path it resolves beautifully!
我想到了另一个解决方案,它需要将 Web 应用程序安装到模拟/social"关键字重定向的虚拟目录.这将导致 asp.net 更新 HttpRuntime.AppDomainAppVirtualPath 以在页面上的引用中包含/social",因此会正确解析.
Another solution occurred to me which required installing the web application to a virtual directory which mimicked the "/social" keyword redirect. This would cause asp.net to update the HttpRuntime.AppDomainAppVirtualPath to include the "/social" in the references on the page and would therefore resolve correctly.
