关于的google curl的get返回

用curl抓取google的搜索结果后返回302错误，在网上搜了一下，加了cookies后就正常返回

header('Content-Type: text/html; charset=utf-8'); $cookie_file = dirname(__FILE__).'/cookie.txt'; //先获取cookies并保存 $url = "http://www.google.co.jp"; $ch = curl_init($url); //初始化 curl_setopt($ch, CURLOPT_HEADER, 0); //不返回header部分 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //返回字符串，而非直接输出 curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file); //存储cookies curl_exec($ch); curl_close($ch); //使用上面保存的cookies再次访问 $url = "http://www.google.co.jp/search?oe=utf8&ie=utf8&source=uds&hl=zh-CN&q=kkk"; $ch = curl_init($url); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file); //使用上面获取的cookies $response = curl_exec($ch); curl_close($ch); echo $response;
