Before I start: I'm programming for Iphone, using objective C.
I have already implemented a call to a web service function using NSURLRequest and NSURLConnection and SOAP. The function then returns a XML with the info I need.
The code is as follows:
NSString *soapMessage = [NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
"<soap:Body>\n"
"<function xmlns=\"http://tempuri.org/\" />\n"
"</soap:Body>\n"
"</soap:Envelope>\n"];
NSURL *url = [NSURL URLWithString:@"http://myHost.com/myWebService/service.asmx"]; //the url to the WSDL
NsMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMessage length]];
[theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue:msgLength forHTTPHeaderField:@"Content-Lenght"];
[theRequest setHTTPMethod:@"POST"];
[theRequest addValue:@"myhost.com" forHTTPHeaderField:@"Host"];
[theRequest addValue:@"http://tempuri.org/function" forHTTPHeaderField:@"SOAPAction"];
[theRequest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
I basically copy and modified the soap request the web service gave as an example.
i also implemented the methods
didRecieveResponse
didRecieveAuthenticationChallenge
didRecievedData
didFailWithError
connectionDidFinishLoading.
And it works perfectly.
Now I need to send 2 parameters to the function: "location" and "module".
I tried modifying the soapMessage like this:
NSString *soapMessage = [NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
"<soap:Body xmlns=\"http://tempuri.org/\" />\n"
"<m:GetMonitorList>\n"
"<m:location>USA</m:location>\n"
"<m:module>DEVELOPMENT</m:module>\n"
"</m:GetMonitorList>\n"
"</soap:Body>\n"
"</soap:Envelope>\n"];
But is not working...any thoughts how should I modify it?
Extra info:
it seems to be working... kind of.
But the webservice return nothing.
During the connection, the method
didReceiveResponse execute once and
the didFinishLoading method executes
as well. But not even once the method
didReceiveData.
I wonder if, even though there is no
USA locations, it will still send at
least something?
is there a way to know which are the
parameters the function is waiting
for?
I don't have access to the source of the webservice but i can access the WSDL.
