iphone - 服务器无法识别 iPhone 中 HTTP header SOAPAction 的值？

Question

我正在尝试将 web 服务连接到我的代码，但出现错误

"Server did not recognize the value of HTTP Header SOAPAction"

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"
                         "<Hello xmlns=\"http://viium.com/\">\n"
                         "<name>%@</name>\n"
                         "</Hello>\n"
                         "</soap:Body>\n"
                         "</soap:Envelope>\n", @"new"
                         ];
NSLog(soapMessage);

NSURL *url = [NSURL URLWithString:@"http://viium.com/WebService/HelloWorld.asmx"];
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://viium.com/Hello" forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

请指导我缺少什么？

NSURL *url = [NSURL URLWithString:@"https://servername.com/WebService/WebServicename.asmx"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMessage length]];
[theRequest addValue:@"text/xml" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue:@"servername.com/Hello" forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection  *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
