- //◆ 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;
- //◆ 接口請求成功時,需對返回參數使用平台提供的公鑰進行驗簽,传送的sign参数不参与签名,将生成的签名与该sign值作校验。

- // @param data 待拼接的数据
- // @param sep 连接符
- // @param onlyValues 是否只包含参数值,true则不包含参数名,否则参数名和参数值均有
- // @param includeEmpty 是否包含空值,true则包含空值,否则不包含,注意此参数不影响参数名的存在
- // @param exceptKeys 被排除的参数名,不参与排序及拼接
- // @return string
