I am attempting to do a proof-of-concept consumption of a web service using Delphi 2010 and Indy. My code at this point is:
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;
Note: I am particularly uncertain about this line just before the POST
lHTTP.Request.CustomHeaders.Add('SOAPAction: "http://edd.ca.gov/SendTransmission"');
According to the web service documentation, I should be getting either an ACK1 success or an ACK1 error with an explanation. Here is the result I am getting at this point:

I have been in phone and email contact with the agency that maintains the web service (the California EDD). They are motivated to get as many people as possible to adopt this technology and reduce the amount of paper they have to handle but their they don't have in depth knowledge of the system because it was created by an outside vendor.
I have downloaded SOAPUI to try to understand the service better and eliminate any errors that might be caused by my implementation and possible misuse of the Indy library. I'm not sure how to use SOAPUI for this purpose. The instructions don't seem to address my situation. If I load the WSDL into the program and attempt to test one of the functions, I get the result that the test finished with status [FINISHED] and I don't know what to make of that.
I would appreciate any help on my little problem.
SoapUI is the way to go, to see how things should work. Use the RIO.OnBeforeExecute and AfterExecute events to examine the XML that you're sending and receiving. Compare those to what SoapUI sends and receives. Ignore differences in namespaces, which shouldn't matter. Ideally, you should be able to take the XML coming out of the OnBeforeExecute event (save the stream to a text file or log), paste into SoapUI, (right-click to clean-up/reformat in SoapUI) and see if the XML makes sense, and see what happens when you submit that.
If it turns out that your XML is close to working, but a 'tweak' is needed, you can edit the XML in the OnBeforeExecute event with StringReplace, etc., and 'fix' the XML so it works.
