HomeBackend DevelopmentPHP Tutorial微信内置浏览器打开的网页,获取微信用户openid

微信浏览器获取用户信息是经常可以看到的,但是对于微信浏览器获取用户信息究竟如何实现?这篇文章将给你说明微信浏览器获取用户信息的问题。

我已开通300元的开发者账号。  
需求如下:  
现有一wap网页,用户使用微信内置浏览器打开( 通过微信朋友圈/朋友分享,或微信扫网页二维码等方式进入,与公众号无关),该网页如何获取用户的微信openid呢?  
 
按照官方的微信登录帮助,是可以实现扫码登录,但是针对PC版的--微信扫码,电脑端登录。而我的情况是当前网页是在手机微信打开的,还怎么扫码呢?  
 
我见有些网站是可以实现的,会弹出授权提示框,但不知是如何实现的?谢谢了!!

看看这个

微信内置浏览器获取用户的微信openid,微信公众平台OAuth2.0网页授权  
-----------------------------------------------------------------------------------------------  
首先你的网站入口必须是微信服务号(开通认证、拥有获取用户openid权限;订阅号是不行的)。  
网页通过微信的Oauth2认证链接。  
 
然后通过服务号菜单链接进入网站,如: https://open.weixin.qq.com/connect/oauth2/authorize?appid=YOURAPPID&redirect_uri=http://YOUWEBSITE/oauth2.php&response_type=code&scope=snsapi_base&state=STATE#wechat_redirect  
 
自己根据微信提供的oauth2接口文档,编写oauth2.php内容,(网上有相关官方SDK)  
按下面的步骤:  
1.获取用户openid  
2.获取accesson_token  
3.获取用户信息  
4.授权注册用户,若已存在该用户则直接进入网站。 

微信里面打开出现授权提示框,这个是微信公众号的登陆  
当用户点击授权后,会跳转到你的页面,参数里面就会带上token  
然后你再通过token调用接口,查询openid等等

有的页面,用外部浏览器打开就会有如下提示,有的就没有,是怎么做到的呢?
