Iphone 无法从服务器共享点获取响应 -（NSString*）getSoap{ NSString*getEnvelopeData=[NSString stringWithFormat: @“\n” “\n” “\n” "http://tempuri.org/IHelloWorldService/GetData\n“ “urn:uuid:e2c3af4e-5d69-4fd8-94bd-0e0f00976dad\n” “\n” "http://www.w3.org/2005/08/addressing/anonymous\n“ “\n” “\n” “\n” “\n” “0\n” “\n” “\n” “\n”]； 返回getEnvelopeData； } -（无效）加载请求{ NSString*soapMessage=[self-getSoap]； NSLog（@“soapMessage%@”，soapMessage）； NSString*urlString=@”http://l-156024038.testad.com:9000/HelloWorldService.svc"; NSURL*url=[NSURL URLWithString:urlString]； NSMutableURLRequest*theRequest=[[NSMutableURLRequest alloc]initWithURL:url]； NSString*msgLength=[NSString stringWithFormat:@“%d”，[soapMessage length]]； [请求设置值：@“gzip”用于HttpHeaderField:@“接受编码”]； [theRequest addValue:@“text/xml；charset=utf-8”用于HttpHeaderField:@“Content Type”]； [theRequest addValue:msgLength for HttpHeaderField:@“内容长度”]； [HttpHeaderField的请求附加值：@“l-15620438.testad.com:@“主机”]； [TheRequestAddValue:@“GetData”用于HttpHeaderField:@“SOAPAction”]； [请求设置值：@“基本”用于HttpHeaderField:@“授权”]； //theRequest=[NSMutableUrlRequestWithURL:url缓存策略：NSURLRequestReloadIgnoringLocal和RemoteCacheData timeoutInterval:45]； [TheRequestSetHttpMethod:@“获取”]； [TheRequestSetHttpBody:[soapMessage数据使用编码：NSUTF8StringEncoding]； 连接=[[NSURLConnection alloc]initWithRequest:theRequest委托：self]； if（连接） { webData=[NSMutableData]； } 其他的 { NSLog（@“连接为空”）； } } //此时，连接已设置，委托已设置为self，现在是使用连接委托方法的时候了。我们将使用四种方法： -（void）连接：（NSURLConnection*）连接DidReceiverResponse：（NSURResponse*）响应{ NSLog（@“响应值%@”，响应）； } -（void）连接：（NSURLConnection*）连接didReceiveData:（NSData*）数据 { [webData:data]； NSLog（@“数据接收%@”，webData）； } -（无效）连接：（NSURLConnection*）连接失败错误：（NSError*）错误{ NSLog（@“连接错误%@”，错误）； }

从上面的代码中，我无法从服务器获得响应

它总是调用错误的委托方法

@Sixten Otto Error with connection Error Domain=kCFErrorDomainCFNetwork Code=303“操作无法完成。（kCFErrorDomainCFNetwork Error 303。）”UserInfo=0x6a37870{nSerrorFailingUrlkey一些随意的谷歌搜索表明303错误代码可能是格式错误的HTTP请求/响应。我会尝试删除您的显式主机和内容长度（系统应该能够派生）然后继续运行，直到从服务器得到响应（这可能是某种故障），然后查看您的位置。
