通过HTTPS授权失败TIdHTTP

标签： delphi delphi-xe2 indy

我想接近Exchange Web服务并自己处理XML SOAP组合（请求）和解析（响应）。 因此，THTPPRIO似乎有点矫枉过正。

我正在尝试TIdHTTP，但我坚持认证;使用Delphi XE2更新4和Indy 10.5.8.0

以下是代码：

idHTTP1.Request.CustomHeaders.AddValue('SOAPAction','"http://schemas.microsoft.com/exchange/services/2006/messages/ResolveNames"');
IdHTTP1.Post('https://webmail.mailserver.nl/ews/exchange.asmx',TSRequest,TSResponse);
  • TSRequest，TSResponse是UTF-8 TStringStreams，TSRequest包含 整个SOAP信封
  • IdHTTP1.IOHandler设置为a TIdSSLIOHandlerSocketOpenSSL，每this advice TIdSSLIOHandlerSocketOpenSSL.Intercept链接到TIdLogDebug 我可以调试正在发生的事情
  • OpenSSL DLL存在于DLL搜索路径中
  • EWS需要NTLM验证; TIdNTLMAuthentication在uses子句中;我有 设置idHTTP1.Request.BasicAuthentication = false，用户名和 填写密码
  • IdHTTP1.OnSelectAuthorization事件确认NTLM身份验证 （参数AuthenticationClass = TIdSSPINTLMAuthentication，和 AuthInfo TIdHeaderList包含'谈判'，'NTLM'）
  • 没有代理。我通过Fiddler代理，看看是什么 继续，但没有区别。

我也尝试过设置用户/ PW运行时间：

procedure TForm1.IdHTTP1Authorization(Sender: TObject; Authentication: TIdAuthentication; var Handled: Boolean);
begin
  Authentication.Username := 'bob@domain.nl';
  Authentication.Password := 'password';
  Handled := true;
end;

发送的HTTP（来自TIdLogDebug.OnSend）以：

开头 
POST /ews/exchange.asmx HTTP/1.1
Content-Type: text/xml; charset=utf-8
Content-Length: 562
SOAPAction: "http://schemas.microsoft.com/exchange/services/2006/messages/ResolveNames"
Host: webmail.mailserver.nl
Accept: text/html, */*
Accept-Encoding: gzip,deflate, identity
User-Agent: Mozilla/3.0 (compatible; Indy Library)


<soapenv:Envelope

收到的HTTP（来自TIdLogDebug.OnReceive）是

我在传出的HTTP中错过的是一行（例如由SOAPUI生成）：

"Authorization: NTLM TlRMTVNTUAABAAAANQIIIBQAFAAyAAAAEgASACAAAABWAE0ASgBBAE4AVABUADcANABUAEkATQBFAFQARQBMAEwAQgBWAA==[\r][\n]"

也许我没有在正确的位置指定用户名/ PW？

在Remy的初步回答之后添加了11月13日：

为了进行比较，我从SOAPUI调用了web服务，这显示 6个数据包越过该行，响应两次UnAuthorized。

所以从Delphi我只看到前2个数据包交换。奇怪的是，如果我再次单击“测试”按钮 ，交换似乎会继续???：

如果我点击我的测试按钮第三次，我会得到一个实际的EIdHTTPProtocolException和这个数据交换：

通常，在服务器通过401回复请求之前，不会发送Authorization标头。您不会在初始请求中看到它，但TIdHTTP应该在处理401回复后发送带有Authorization标头的新请求。在任何情况下，您都应该使用TIdHTTP.Request.Username和TIdHTTP.Request.Password属性来设置初始凭据，然后使用OnAuthorization事件根据需要提供新凭据。
