我正在尝试使用Delphi 2010和Indy进行Web服务的概念验证消费。我的代码是：
procedure TForm1.Log(const sEvent, sMsg: String);
const sPrior: String = '';
begin
if sEvent <> sPrior then begin
mTraffic.Lines.Append('');
mTraffic.Lines.Append(Format('%s: %s', [sEvent, FormatDateTime('mm/dd/yyyy hh:nn:ss.zzz', Now)]));
mTraffic.Lines.Append('--------------------------------------------------------------------------------');
sPrior := sEvent;
end;
mTraffic.Lines.Append(sMsg);
Application.ProcessMessages;
end;
function TForm1.BuildRequest: String;
const MINPERDAY = 1440;
var slRequest: TStringList;
sFileName: String;
sID: String;
sGUID: String;
oDoc: TNativeXML;
oNode: TXmlNode;
uNow: _SystemTime;
dtNow: TDateTime;
sNow: String;
sNonce: String;
oIdmd5: TIdHashMessageDigest5;
begin
sFileName := 'Send.xml';
slRequest := TStringList.Create;
oIdmd5 := TIdHashMessageDigest5.Create;
oDoc := TNativeXML.Create;
try
oDoc.LoadFromFile(sFileName);
SetAttrib(oDoc, 'inputMessage', 'utc', FormatDateTime('m/d/yyyy hh:mm:ss am/pm', Now));
sGUID := 'urn:uuid' + MyCreateUUID;
SetAttrib(oDoc, 'inputMessage', 'messageId', sGUID);
SetNode(oDoc, 'wsa:messageId', sGUID);
Windows.GetSystemTime(uNow);
dtNow := SysUtils.SystemTimeToDateTime(uNow);
sNow := FormatDateTime('yyyy-mm-dd"T"hh:mm:ss"Z"', dtNow);
sNonce := oIdmd5.HashStringAsHex(sNow + 'Jack' + 'Test' + 'Salt');
SetNodes(oDoc, 'wsu:Created', FormatDateTime('yyyy-mm-dd"T"hh:mm:ss"Z"', dtNow));
SetNode(oDoc, 'wsu:Expires', FormatDateTime('yyyy-mm-dd"T"hh:mm:ss"Z"', dtNow + 5 /MINPERDAY));
SetNode(oDoc, 'wsse:Nonce', sNonce);
SetNode(oDoc, 'ElectronicPostmark', FormatDateTime('yyyy-mm-dd"T"hh:mm:ss.zz-8.00', dtNow));
SetNode(oDoc, 'wsse:Username', '#MyUserName#');
SetNode(oDoc, 'wsse:Password', '#MyPassword#');
oDoc.XmlFormat := xfReadable;
Result := oDoc.WriteToString;
finally
slRequest.Free;
oIdmd5.Free;
oDoc.Free;
end;
end;
function TForm1.SSLPost(const url: String; sRequest: String): String;
var lHTTP: TIdHTTP;
lIOHandler: TIdSSLIOHandlerSocketOpenSSL;
lIDLogDebug: TIdLogDebug;
ss: TStringStream;
begin
lHTTP := TIdHTTP.Create(nil);
lIOHandler := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
lIDLogDebug := TIdLogDebug.Create(nil);
ss := TStringStream.Create;
try
ss.WriteString(sRequest);
ss.Position := 0;
lIOHandler.SSLOptions.Method := sslvSSLv3;
lIOHandler.OnStatusInfo := IdSSLIOHandlerSocketOpenSSL1StatusInfo;
lHTTP.IOHandler := lIOHandler;
lIdLogDebug.OnSend := IdLogDebug1Send;
lIDLogDebug.OnReceive := IdLogDebug1Receive;
lIDLogDebug.Active := True;
lHTTP.Intercept := lIdLogDebug;
try
lHTTP.Request.CustomHeaders.Add('SOAPAction: "http://edd.ca.gov/SendTransmission"');
Result := lHTTP.Post(url, ss);
except
On e: Exception do begin
Result := e.Message + #13#10 + '**No Response**';
end;
end;
finally
lHTTP.Free;
lIOHandler.Free;
lIdLogDebug.Free;
ss.Free;
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
var sResponse: String;
begin
sResponse := SSLPost('https://FSETTESTPROD.EDD.CA.GOV', BuildRequest);
Log('Response', sResponse);
end;
注意：我在POST之前对这一行特别不确定
lHTTP.Request.CustomHeaders.Add('SOAPAction: "http://edd.ca.gov/SendTransmission"');
根据Web服务文档，我应该获得ACK1成功或ACK1错误以及解释。这是我在这一点上得到的结果：

我一直与维护网络服务的机构（加利福尼亚州EDD）进行电话和电子邮件联系。他们的动机是让尽可能多的人采用这种技术并减少他们必须处理的纸张数量，但他们对系统没有深入的了解，因为它是由外部供应商创建的。
我已下载SOAPUI以尝试更好地理解服务，并消除可能由于我的实现和可能滥用Indy库而导致的任何错误。我不确定如何使用SOAPUI来实现此目的。说明似乎没有解决我的情况。如果我将WSDL加载到程序中并尝试测试其中一个函数，我得到的结果是测试以状态[FINISHED]结束，我不知道该怎么做。
对于我的小问题，我将不胜感激。
答案 0 :(得分：6)
SoapUI是要走的路，看看事情应该如何运作。使用RIO.OnBeforeExecute和AfterExecute事件检查您要发送和接收的XML。将它们与SoapUI发送和接收的内容进行比较。忽略命名空间的差异，这无关紧要。理想情况下，您应该能够从OnBeforeExecute事件中取出XML（将流保存到文本文件或日志中），粘贴到SoapUI中，（右键单击以在SoapUI中清理/重新格式化）并查看XML是有道理的，看看你提交时会发生什么。
如果事实证明您的XML接近工作，但需要“调整”，您可以使用StringReplace等在OnBeforeExecute事件中编辑XML，并“修复”XML以使其正常工作。
