使用者透過掃描網頁提供的二維碼實現登陸資訊獲取

/**
 * 微信公眾平台PHP-SDK
 * Wechatauth為非官方微信登陸API
 * 使用者透過掃描網頁提供的二維碼實現登陸資訊取得
 * 主要實現以下功能:
 * get_login_code() 取得登陸授權碼, 透過授權碼才能取得二維碼
 * get_code_image($code='') 將上面取得的授權碼轉換為圖片二維碼
 * verify_code() 鑑定是否登陸成功,回傳200為最終授權成功.
 * get_login_cookie() 鑑定成功後呼叫此方法即可取得使用者基本資訊
 * sendNews($account,$title,$summary,$content,$pic, $srcurl='') 向一個微信帳戶發送圖文資訊
 * get_avatar($url) 取得使用者頭像圖片資料
