/**
* 微信支付帮助库
* ====================================================
* 接口分三种类型：
* 【请求型接口】--Wxpay_client_
* 统一支付接口类--UnifiedOrder
* 订单查询接口--OrderQuery
* 退款申请接口--Refund
* 退款查询接口--RefundQuery
* 对账单接口--DownloadBill
* 短链接转换接口--ShortUrl
* 【响应型接口】--Wxpay_server_
* 通用通知接口--Notify
* Native支付——请求商家获取商品信息接口--NativeCall
* 【其他】
* 静态链接二维码--NativeLink
* JSAPI支付--JsApi
* =====================================================
* 【CommonUtil】常用工具：
* trimString()，设置参数时需要用到的字符处理函数
* createNoncestr()，产生随机字符串，不长于32位
* formatBizQueryParaMap(),格式化参数，签名过程需要用到
* getSign(),生成签名
* arrayToXml(),array转xml
* xmlToArray(),xml转 array
* postXmlCurl(),以post方式提交xml到对应的接口url
* postXmlSSLCurl(),使用证书，以post方式提交xml到对应的接口url
