首先需要一个沙箱环境,专门为开发者提供的。里面给你提供了卖家账号,和买家账号。具体的自行百度。
需要下载沙箱版的支付宝,然后登陆提供的买卖家账号即可操作。因为在沙箱环境中支付宝给出的二维码只能在沙箱版的支付宝中扫。

当面付demo

需要一个sra2秘钥生成器,支付宝有提供下载:

场景:用户下单,然后我们后台会去掉支付宝的接口,当然支付宝接口需要一些参数,比如说,标题了,订单号,总金额,物品明细,等等之类的,这些支付宝官方的demo中都有,直接拿过来改造就行。我们主要的是掉支付宝的接口让他给我们返回一个json串,里面有个网址,生成二维码的。然后我们再用这个一个工具包将这个二维码生成二维码,保存到我们的图片服务器上。然后,我们用刚刚下载好的沙箱支付宝扫码支付。然后,支付成功,支付宝会会回调我们之前设置的本地的回调函数(内网映射)。参数中有支付宝返回的结果,比如订单号,支付状态,支付时间等等,但是这些都时支付宝给我们的一些结果,在这之前,我们必须要验证一下这个回调函数是不是支付宝发起的,支付包的demo里有提供这个方法,返回的是布尔值。然后是true的时候,进行我们下一步的操作,就是验证返回的结果的参数正确性和更该数据库里面的状态。最后如果支付成功,给支付宝返回success,不然,支付宝会隔一段时间还回调,具体看文档。大致流程就是这样的。不会的给我留言。。。。
