关于微信开发记录

//开发情况是前后端完全分离

微信授权

appid//为改授权公众号的appid

redirect_uri//为微信回调后台的接口地址

redirect_uri2//为后台回调前端地址

window.location.href  = "https://open.weixin.qq.com/connect/oauth2/authorize?appid="+appid+"&redirect_uri="+redirect_uri+"&response_type=code&scope=snsapi_userinfo&state="+redirect_uri2+"#wechat_redirect";

openid从后台在回调的地址后拼接参数的方式拿

//吊起微信支付
