cookies是刷新到下一个网页之后才生效的。比如你在A网页设置cookie,这时候无效,跳转到B、C、D之后,才有效的。

那这段代码,手机微信返回 错误,是哪里出了问题?而电脑微信没有问题,微信开发者工具也没有问题!

错误内容是:{ "errcode": 40163, "errmsg": "code been used, hints: [ req_id: 99_hNA05062271 ]" }

1、你应该是重复使用了code导致的。建议你在你的代码那里加入msgbox调试,看弹出到哪里报错。

 

2、简化你的代码不要太复杂,先测试出问题。

 

3、代码太多别人服务查看和调试。
