Apache上的ISAPI Web服务

时间：2010-11-25 09:41:31

标签： delphi apache delphi-7 isapi

我在Delphi 7中使用客户端的WebService（ISAPI DLL）。当我用我的客户端调用我的WebService时，一切正常。问题出在另一家公司的.NET客户端。如果作为服务器runnig apache（使用isapi-handler），则Web服务不会运行。在IIS服务器上一切正常。

问题在于函数HttpExtensionProc（var ECB：TEXTENSION_CONTROL_BLOCK）：DWORD;来自ISAPIApp.pas。在此入口点缺少内容数据（ECB.cbTotalBytes = 0，ECB.lpbData =''）。但仅限于Apache（2.2.17）和.NET客户端。

哪里有问题？如果调用者是.NET而服务器是Apache，为什么ECB.lpbData不包含SOAP请求？

感谢您帮助解决问题。

我尝试在apache中启用调试日志并使用DumpIO模块，并且.NET调用中不存在soap请求。如果调用来自Delphi客户端，则SOAP请求将记录在调试日志中。

2 个答案:

答案 0 :(得分：1)

我知道这个主题有点老了，但是因为这是搜索此问题时的第一个问题，我认为解决方法（至少对于能够访问.net客户端的人来说）是有道理的。

问题是标题和soap正文分两步发送，由标题

表示 
Expect: 100-continue

我没有发现这是Apache，mod_isapi还是delphi的问题，但是可以在.net客户端中禁止发送此标头：

System.Net.ServicePointManager.Expect100Continue = false;

我在这里找到了解决方案http://haacked.com/archive/2004/05/15/http-web-request-expect-100-continue.aspx

我希望这会对某人有所帮助。

答案 1 :(得分：0)

我能够从Delphi 7创建一个Apache模块（不需要Apache ISAPI包装器），对HTTPD2.pas进行一些更改以支持Apache 2.

http://xxm.svn.sourceforge.net/viewvc/xxm/trunk/Delphi/apache/

但是，我没有做太多的SOAP。所以我不确定如何将request_rec链接到处理SOAP请求并获得发送响应所需的工作。
