用户通过扫描网页提供的二维码实现登陆信息获取
  1. /**
  2. * 微信公众平台PHP-SDK
  3. * Wechatauth为非官方微信登陆API
  4. * 用户通过扫描网页提供的二维码实现登陆信息获取
  5. * 主要实现如下功能:
  6. * get_login_code() 获取登陆授权码, 通过授权码才能获取二维码
  7. * get_code_image($code='') 将上面获取的授权码转换为图片二维码
  8. * verify_code() 鉴定是否登陆成功,返回200为最终授权成功.
  9. * get_login_cookie() 鉴定成功后调用此方法即可获取用户基本信息
  10. * sendNews($account,$title,$summary,$content,$pic,$srcurl='') 向一个微信账户发送图文信息
  11. * get_avatar($url) 获取用户头像图片数据
