I referred this link &发现它非常有用，但当我开始尝试所有可能的方法时，我无法获得所需的输出。

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]];

我想我一定是犯了个小错误。我得到了以下输出。

                        <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.)

            </div>
        </div>
    </div>
</body>

有人能帮我理解我做错了什么吗？有什么可以帮上忙的吗？

我找到了解决方案:更正soap消息中的第二行。

"<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"

url字符串中也缺少.svc扩展名。我用声明更正了它。service.svc中的s是小写的，而参数中的s是大写的。

下面是带有http头参数的整个soap消息。

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]];

有一件事仍然让我感到困惑，那就是即使是一个GET请求，当我将它改为POST时，它也会抛出"ERROR in Connection“NSLog & succeeds
