/**
 * 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
