<?php
/**
* 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
