  包括一个Obj-C gzip包装器，例如NSData+GZip，并用它来编码 NSURLRequest 的主体 . 另外请记住相应地设置 Content-Encoding ，以便网络服务器知道如何处理您的请求 .

  NSData *requestBodyData = [yourData gzippedData];
  NSString *postLength = [NSString stringWithFormat:@"%d", requestBodyData.length];
  [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
  [request setValue:@"gzip" forHTTPHeaderField:@"Content-Encoding"];
  [request setHTTPBody:requestBodyData];

  执行一些常规方法，例如以下内容并设置适当的Header可能会对您有所帮助 .

  // constructing connection request for url with no local and remote cache data and timeout seconds
  NSMutableURLRequest *request =[NSMutableURLRequest requestWithURL:[NSURL URLWithString:callingWebAddress]];// cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:timoutseconds];
  [request setHTTPMethod:@"POST"];
  
  NSMutableDictionary *headerDictionary = [NSMutableDictionary dictionary];
  [headerDictionary setObject:@"application/json, text/javascript" forKey:@"Accept"];
  [headerDictionary setObject:@"application/json" forKey:@"Content-Type"];
  
  //Edit as @centurion suggested
  [headerDictionary setObject:@"Content-Encoding" forKey:@"gzip"];
  [headerDictionary setObject:[NSString stringWithFormat:@"POST /Json/%@ HTTP/1.1",method] forKey:@"Request"];
  [request setAllHTTPHeaderFields:headerDictionary];
  
  // allocation mem for body data
  self.bodyData = [NSMutableData data];
  
  [self appendPostString:[parameter JSONFragment]];
  
  // set post body to request
  [request setHTTPBody:bodyData];
  
  NSLog(@"sending data %@",[[[NSString alloc] initWithData:bodyData encoding:NSUTF8StringEncoding]autorelease]);
  
  // create new connection for the request
  // schedule this connection to respond to the current run loop with common loop mode.
  NSURLConnection *aConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
  //[aConnection scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes];
  self.requestConnenction = aConnection;
  [aConnection release];
