微信公眾平台OAuth2.0網頁授權php範例

用戶透過掃描網頁提供的二維碼實現登陸資訊獲取，大家參考使用吧 
請先下載  snoopy 類別 

代碼如下: 
/**
*  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以取得 
*  主要實現以下功能: *授權碼才能取得二維碼 
*  get_code_image($code='') 將上述取得的授權碼轉換為圖片二維碼 
*  verify_code() 鑑定是否登陸成功,返回200為最終授權成功. 
*  get_login_cookie( ) 鑑定成功後呼叫此方法即可取得使用者基本資訊 
*  sendNews($account,$title,$summary,$content,$pic,$srcurl='') 傳送圖文資料  get_avatar($account,$title,$summary,$content,$pic,$srcurl='') 傳送圖文資料  get_avatar( $url) 取得使用者個人資料圖片資料
