ios - 使用 AFNetworking 在网络请求中添加标头不起作用

Question

我使用以下代码发出包含标头 Authorization 的 GET 请求，但似乎不起作用...... get 请求不包含授权令牌。有任何想法吗？

   // 1 - define resource URL
    
    NSURL *URL = [NSURL URLWithString:@"https://myurl"];
    
    AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
    AFHTTPRequestSerializer *requestSerializer = [AFHTTPRequestSerializer serializer];
    [requestSerializer setValue:[NSString stringWithFormat:@"Bearer %@",Token] forHTTPHeaderField:@"Authorization"];
    
   manager.requestSerializer = requestSerializer;

    //3 - set a body
    NSDictionary *body =@{@"email":@"a@gmail.com"};
    //4 - create request
    [manager GET:URL.absoluteString
       parameters:body
       
         progress:nil
     //5 - response handling
          success:^(NSURLSessionDataTask * _Nonnull task, NSDictionary *responseObject) {
        
            NSLog(@"Reply POST JSON: %@", responseObject);

    }
          failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"error on machine token: %@", error);
    }
    ];
