AFNetworking 2.0 //如何读取响应头

Question

我正在使用新版本的AFNetworking,我无法弄清楚如何阅读响应的标题.我正在使用AFHTTPSessionManager来执行我的查询,一切正常但我无法找到标题响应字段.

这是我如何进行

     self.sessionManager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:BASE_URL]];
     [self.sessionManager GET:urlId parameters:nil
                      success:^(NSURLSessionDataTask *task, id responseObject) {

                          if ([self.delegate respondsToSelector:@selector(userIsLoadedWithInfos:)]) {
                              [self.delegate userIsLoadedWithInfos: responseObject];
                          }
                      } failure:^(NSURLSessionDataTask *task, NSError *error) {
                          if ([self.delegate respondsToSelector:@selector(userLoadingFailed)]) {
                              [self.delegate userLoadingFailed];
                          }
                      }
         ];

我尝试读取任务的响应属性,但它返回一个不包含标题的NSURLResponse.现在有人如何阅读2.0版本的响应标头？谢谢

一个比Viruss mcs更强大的代码:

if ([task.response isKindOfClass:[NSHTTPURLResponse class]]) {
    NSHTTPURLResponse *r = (NSHTTPURLResponse *)task.response;
    NSLog(@"%@" ,[r allHeaderFields]);
}

回报

{
    Connection = "Keep-Alive";
    "Content-Length" = 12771;
    "Content-Type" = "application/json";
    Date = "Fri, 06 Dec 2013 10:40:48 GMT";
    "Keep-Alive" = "timeout=5";
    "Proxy-Connection" = "Keep-Alive";
    Server = "gunicorn/18.0";
}

同样地,你可以确保施放是正确的[response respondsToSelector:@selector(allHeaderFields)],但你也应该在进行施法之前调用它

if ([task.response respondsToSelector:@selector(allHeaderFields)]) {
    NSHTTPURLResponse *r = (NSHTTPURLResponse *)task.response;
    NSLog(@"%@" ,[r allHeaderFields]);
}

或根本没有演员表:

if ([task.response respondsToSelector:@selector(allHeaderFields)]) {
    NSLog(@"%@" ,[task.response performSelector:@selector(allHeaderFields)]);
}

Answer 2

你有没有试过从NSURLResponse获取返回的头文件,

您可以尝试使用NSURLResponse对象,

NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response;
if ([httpResponse respondsToSelector:@selector(allHeaderFields)]) {
    NSDictionary *dictionary = [httpResponse allHeaderFields];
    NSLog([dictionary description]);
}

希望对你有帮助.!
