只需使用 NSMutableURLRequest 和 sendAsynchronousRequest 进行正常的 HTTP 发布。但是我传入的 NSHTTPURLResponse 对象在调用后的 statusCode 为零。我收到此错误：
sendAsynchronousRequest 错误=错误域=NSURLErrorDomain 代码=-1005“网络连接丢失。” UserInfo=0xb374a00 {NSErrorFailingURLStringKey=
http://54.221.224.251, NSErrorFailingURLKey=http://54.221.224.251, NSLocalizedDescription=网络连接丢失。, NSUnderlyingError=0xb587990 "网络连接丢失。"} 2013-09-04 16:46:19.146 panic[2032:5907] statusCode: 0
但没有状态码。为什么？服务器发送的状态码是 150。
当我向服务器发布不同的数据并且不要求它返回 statusCode 时，连接会顺利进行并且符合预期。
应用代码：
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
if (error)
NSLog(@"sendAsynchronousRequest error = %@", error);
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
int code = [httpResponse statusCode];
NSString *coder = [NSString stringWithFormat:@"%d",code];
NSLog(@"%@",coder);
if (data) {
NSLog(@"This is Data: %@",data);
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
int code = [httpResponse statusCode];
NSString *coder = [NSString stringWithFormat:@"%d",code];
NSLog(@"%@",coder);
}
}];
