SVC webservice - objective-c

问题

I referred this link & found it very useful but when I started trying every possible of it I failed in getting the desired output.

NSString *soapMessage = [NSString stringWithFormat:
                         @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                         "<SOAP:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
                         "<SOAP:Body>\n"
                         "<BindCategory xmlns=\"http://tempuri.org/\">\n"
                         "</SOAP:Body>\n"
                         "</SOAP:Envelope>\n"
                         ];

NSLog(@"soapMessage: \n%@",soapMessage);

NSURL *url = [NSURL URLWithString:@"http://assetwebservice.sudesi.in/Service/"];

NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];

[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"http://tempuri.org/IService/BindCategory" forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

I think I must be doing some minor mistake. I am getting following output.

                        <li>
                            2) The link you used to get here is faulty.

                        <li class="last">
                            (It's an excellent idea to let the link owner know.)
                        </li>
                    </ol>
                </div>
            </div>
        </div>
    </div>
</body>
</html>

Can anybody help to understand what wrong I am doing? Any help is greatly appreciated?

Hey guys found out the solution. The second line in the soap message corrected.

"<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"

Also in the url string .svc extension was missing. I corrected it with the statement. http://assetwebservice.sudesi.in/service.svc See well the s from service.svc is lower case whereas in soapaction parameter it is upper case.

Below is the entire soap message with http header parameters.

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"
                         "<BindCategory xmlns=\"http://tempuri.org/\">\n"
                         "</BindCategory>\n"
                         "</soap:Body>\n"
                         "</soap:Envelope>\n"
                         ];
NSLog(@"soapMessage: \n%@",soapMessage);

NSURL *url = [NSURL URLWithString:@"http://assetwebservice.sudesi.in/service.svc"];    
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];

[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"http://tempuri.org/IService/BindCategory" forHTTPHeaderField:@"soapaction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

One thing still confuse me is that even if it is a GET request it throws me "ERROR in Connection" NSLog & succeeds when I change it to POST
