报文加密

    MADSingleClass.getInstance.madp_statue_finish = ^(id z) {
        NSInteger type = 3;
        //type = 3 对url/header/body处理

/**
 自定义报文加解密
  包含两种类型，A：只操作body；B：需要借助于url/header/body
  如果使用A类型：
  encryptionsCallBack  输入端为需要加密的body，输出端为加密后的body；
  decryptionsCallBack  输入端为待解密的body，输出端为解密后的body；
  如果使用B类型：
  encryptionsCallBack 输入端为body，输出为{Url:"",Header:{需要添加的key-vlue},Body:"加密后的body"}
  decryptionsCallBack  输入端为{Url:"",Header:{},Body:""}，输出端为解密后的body；
  
  使用B类型，加密的body回传时需要转为Base64格式，该处理只是sdk内部的操作，不涉及服务端的特殊处理。
