ios - 调用 AFNetworking 响应失败 block 而不是成功 block

Question

当我收到状态代码 200 时，AFNetworking 响应 failure block 被调用。我怎样才能让 success 被调用？

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:@"http://128.199.94.58/test/bt/client_token.php" parameters:nil
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
         self.clientToken = responseObject[@"customerID"];
         NSLog(@"Client Token received.");
     }
     failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         // Handle failure communicating with your server
         NSLog(@"Client Token request failed.%@",operation.responseString);
         NSLog(@"error code %ld",(long)[operation.response statusCode]);
     }];

查看error的值。它会告诉您连接失败的原因。此上下文中的“失败”与状态代码无关。返回“404”仍然是“成功”。失败意味着您无法完成操作。
