重新编写打包百度支付（百度智能小程序支付）（百度支付叫什么）

最近由于项目重建，百度支付被重新包装。这次增加了签名处理和用户退款，方便后期开发使用。

由于百度电商开放平台的升级，支付功能被搬到了智能小程序上。具体申请流程:百度收银支付开通指南，(https://smart program . Baidu . com/docs/operations/transform/pay/)。

(注意:在支付业务中，服务电话要填写银行预留手机号，如果填写不正确，会上报银行预留手机号格式验证失败。)

百度支付文档:百度收银接口2.0(https://smartprogram.baidu.com/docs/develop/function/tune _ up _ 2.0/)。

1.申请通过后，填写百度支付的相关配置:

$ config = array(& amp；#39;交易id & amp#39;= & gt& amp#39;& amp#39;//百度收银的财务结算凭证&；#39;app _ key & amp#39;= & gt& amp#39;& amp#39;，//表示应用程序标识的唯一ID#39;私人密钥& amp#39;= & gt& amp#39;& amp#39;，//私钥原始字符串&；#39;公钥& amp#39;= & gt& amp#39;& amp#39;//平台公钥&；#39;通知_网址& amp#39;= & gt& amp#39;& amp#39;，//支付回拨地址)；第二，调用封装的支付方法，将返回的信息传递给百度小程序。
