Web请求属性“ URL”是空的 [英] Web request property "URL" is empty

问题描述

我试图弄清楚如何从请求（ Web.HTTPApp.TWebRequest ）中读取完整 URI。有一个 URL 属性，但是它返回空值，我看不到其他任何可以提供给我的属性。如何获取请求的完整URI？通过Indy 10 TIdHTTPWebBrokerBridge 来使用。

I'm trying to figure out how to read the full URI from a request (Web.HTTPApp.TWebRequest). There is a URL property, however it returns empty, and I don't see any more properties which could give me this. How can I get the complete URI of the request? This is being used via Indy 10 TIdHTTPWebBrokerBridge.

例如...

http://www.mydomain.com:18500/SomePath/SomeFile.html?n=v&a=b

我尝试跟踪此 URL 属性，发现在 IdHTTPWebBrokerBridge中.pas 显然是故意的……

I tried tracking this URL property and found that in IdHTTPWebBrokerBridge.pas this is being left blank, apparently deliberately...

function TIdHTTPAppRequest.GetStringVariable(Index: Integer): AnsiString;
...
  case Index of
    ...
    //INDEX_URL             : Result := AnsiString(FRequestInfo.Document);
    INDEX_URL             : Result := AnsiString(''); // Root - consistent with ISAPI which return path to root 

推荐答案

我不知道为什么 INDEX_URL 返回空字符串。显然，这是故意的。

I don't know why INDEX_URL returns a blank string. Obviously, it was deliberate, though.

如果您更仔细地查看 IdHTTPWebBrokerBridge.pas 代码，您将看到 INDEX_URL 用于返回 FRequestInfo.Document ，该值与 INDEX_PathInfo 和 INDEX_PathTranslated 都返回。因此，您可以尝试使用 TWebRequest.Host ， TWebRequest.ServerPort ， TWebRequest的组合.Path ... 和 TWebRequest.Query 属性来重新创建您要查找的URL（减去协议，您只需要

If you look at the IdHTTPWebBrokerBridge.pas code more carefully, you will see that INDEX_URL used to return FRequestInfo.Document, which is the same value that INDEX_PathInfo and INDEX_PathTranslated both return. So you could try using a combination of the TWebRequest.Host, TWebRequest.ServerPort, TWebRequest.Path..., and TWebRequest.Query properties to recreate the URL you are looking for (minus the protocol, which you will just have to hard-code).

此外，XE +具有 TWebRequest.RawPathInfo 属性，其中 TIdHTTPAppRequest 实现返回Indy的 TIdHTTPRequestInfo.URI 属性值，因此您也应该查看该值。

Also, XE+ has a TWebRequest.RawPathInfo property which TIdHTTPAppRequest implements to return Indy's TIdHTTPRequestInfo.URI property value, so you should look at that as well.
