ajax處理，將需要提交的數據獲取并提交給后臺，后臺處理這個數據。設置CURLOPT_HTTPHEADER頭部信息發送給原來站點的地址，直接送上代碼

????function?login_get($url,$cookie,$data?=?"")
????{
????????$curlobj?=?curl_init();//?初始化
????????curl_setopt($curlobj,?CURLOPT_URL,?$url);//?設置訪問網頁的URL
????????curl_setopt($curlobj,?CURLOPT_RETURNTRANSFER,?true);//?執行之后不直接打印出來
