/*
 一 封装的目的:
 1. 集约管理,如需更换网络管理工具可以轻松应对
 2. 单例的 AFHTTPSessionManager 实例避免内存泄漏,
 3. 单例可以共享 NSURLSession 中的 TCP 通道避免多次握手
 
 二 目前只有四种网络请求方式:
 1. 普通的服务器接口API GET请求
 2. 普通的服务器API POST请求
 3. 资源文件的上传根据文件路径
 4. 资源文件的上传根据 NSData
 
 三 设置BaseURL
 设置BaseURL可以使在此目标服务器的地址,带不带域名都可以

 四 注意:
    如果需要修改 AFManager 的序列化配置来进行请求的话(比如进行图片下载),
    请增加另外一个AFHTTPSessionManager实例, 避免在多线程的情况下修改 AFManager 造成线程不安全.
