【问题描述】：

I referred this link & 发现它非常有用，但是当我开始尝试所有可能的方法时，我未能获得所需的输出。

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]];

我想我一定是犯了一些小错误。我得到以下输出。

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

谁能帮助理解我做错了什么？非常感谢任何帮助？

【解决方案1】：

我找到了解决方案：soap 消息中的第二行已更正。

"<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"

在 url 字符串中也缺少 .svc 扩展名。我用声明纠正了它。 http://assetwebservice.sudesi.in/service.svc 看清楚 service.svc 中的 s 是小写，而在 soapaction 参数中是大写。

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]];

还有一点让我感到困惑的是，即使它是一个 GET 请求，它也会向我抛出“连接错误”NSLog 并在我将其更改为 POST 时成功
