微信扫描二维码登录网站代码示例

微信(小程序)  /  管理员 发布于 3年前   206


/**
 *  微信公众平台PHP-SDK
 *  Wechatauth为非官方微信登陆API
 *  用户通过扫描网页提供的二维码实现登陆信息获取
 *  主要实现如下功能:
 *  get_login_code() 获取登陆授权码, 通过授权码才能获取二维码
 *  get_code_image($code='') 将上面获取的授权码转换为图片二维码
 *  verify_code() 鉴定是否登陆成功,返回200为最终授权成功.
 *  get_login_cookie() 鉴定成功后调用此方法即可获取用户基本信息
 *  sendNews($account,$title,$summary,$content,$pic,$srcurl='') 向一个微信账户发送图文信息
 *  get_avatar($url) 获取用户头像图片数据
 *  @author dodge
 *  @link https://github.com/dodgepudding/wechat-php-sdk
 *  @version 1.1
 *
