|
||||
* ◆ 如何对接沙箱环境？
|
||||
* 1、修改商户自有程序或配置中，微信支付api的链接，如：被扫支付官网的url为：https://api.mch.weixin.qq.com/pay/micropay增加sandbox路径，变更为https://api.mch.weixin.qq.com/sandbox/pay/micropay， 即可接入沙箱验收环境，其它接口类似；
|
||||
* 2、在微信支付开发调试站点（站点链接：http://mch.weixin.qq.com/wiki/doc/api/index.php），按接口文档填入正确的支付参数，发起微信支付请求，完成支付；
|
||||
* 3、验收完成后，修改程序或配置中的api链接（重要！），去掉sandbox路径。对接现网环境。
