        /*******************微信支付的请求和接收数据均需要校验签名,详细方法请参考安全规范-签名算法********************/

        /*
         * 签名算法
         * 签名生成的通用步骤如下:
         * 第一步,设所有发送或者接收到的数据为集合M,将集合M内非空参数值的参数按照参数名ASCII码从小到大排序(字典序),
         * 使用URL键值对的格式(即key1=value1&key2=value2…)拼接成字符串stringA。
         * 特别注意以下重要规则:
         * ◆ 参数名ASCII码从小到大排序(字典序);
         * ◆ 如果参数的值为空不参与签名;
         * ◆ 参数名区分大小写;
         * ◆ 验证调用返回或微信主动通知签名时,传送的sign参数不参与签名,将生成的签名与该sign值作校验。
         * ◆ 微信接口可能增加字段,验证签名时必须支持增加的扩展字段
         * 第二步,在stringA最后拼接上key得到stringSignTemp字符串,并对stringSignTemp进行MD5运算,再将得到的字符串所有字符转换为大写,得到sign值signValue。
         * key设置路径:微信商户平台(pay.weixin.qq.com)-->账户设置-->API安全-->密钥设置
