AFNetworking2.x 使用过程中遇到的问题

1.//以下写一下关于AFNetworking2.0的GET数据请求问题，刚開始的时候没有写以下标红的代码，所以导致有一个问题。错误显演示样例如以下：

Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/html" UserInfo=0x913a3b0

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
    [manager GET:@"<del>http://192.168.1.160/mm/app/index.php?

        NSLog(@"JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
2.关于POST请求也存在同样的问题，我这里没有真实測试，仅仅是简单測了一下。貌似能够。跟上面的问题是一样的解决方法。
