AFNetwork的问题。

Question

我遇到了AFNetworking的问题。 我的web服务期望两个NSString类型的参数返回YES或NO。 我的代码就是这个

  

AFHTTPClient * httpClient = [[AFHTTPClient alloc]   initWithBaseURL：[NSURL URLWithString：@“http://webservice.com”]];

NSMutableURLRequest *request = [httpClient requestWithMethod:@"GET"
                                                        path:path
                                                  parameters:@{
                                @"password":@"password",
                                @"username":@"username"}


                                ];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:request];

operation.outputStream = [NSOutputStream outputStreamToFileAtPath:path append:NO];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)  {

    NSLog(@"success: %@", operation.responseString);


}
                                  failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                                      NSLog(@"error: %@",  operation.responseString);

                                  }
 ];

NSLog(@"%@", operation.request);

[operation start];

不写：

NSLog(@"success: %@", operation.responseString); ou

  

NSLog（@“error：％@”，operation.responseString）;

也就是说，不会进入blcok。

有什么建议吗？
