微信支付问题
先说说我这里的流程
1,用户下单,生成订单及订单号
2,用户微信支付:先动态生成一个支付单号,与订单号表关联,用支付单号去支付。
3,支付成功后,回调地址接收微信传送过来的支付单号,根据支付单号完成订单支付。
我这样设计总觉得不合适,但又想不出好的方案,主要有以下这些疑问
1,每次支付,动态生成支付单号,是否会有问题
2,支付成功后,回调的时候,万一我的服务器挂了,如何补救。
3,因为支付成功回调,是根据动态生成的支付单号去完成订单支付,万一回调地址外泄,被人恶意猜测支付单号,怎么办。
PS:(之所以用动态支付单号支付,是因为用户在支付中途点了取消,再次支付时候,提交不同的订单号,免得微信提示订单重复)
第一次做支付功能,技术不够,望各路大神耐心赐教

1、你可以自己先生成单号,然后再调取支付的。
2、如果回调失败会每隔一段时间再次回调,直到成功或达到一定次数后会停止。
3、签名加密知道了也没用
