php中curl功能的强大我想大家可能还不知道吧,下面我再介绍一个工作中用到的利用curl获取验证码的实例并且可以为造cookie.

 代码如下 复制代码

$CookieFile=tempnam("./tmep","beast");
if(isset($_GET["img"])){
$url = 'http://www.bKjia.c0m/phper/php.htm';//验证码code
$ch = curl_init($url);
curl_setopt($ch,CURLOPT_COOKIEJAR, $CookieFile);//把返回来的cookie信息保存在文件中
curl_exec($ch);
curl_close($ch);
exit();
}   
if(isset($_POST['d'])){
$b=$_POST[d];//验证码
$p="waybillNo=1721269381&inputcode=".$b;
$ch = curl_init();
// 2. 设置选项,包括URL
curl_setopt($ch,CURLOPT_URL, "http://www.bKjia.c0m");
curl_setopt($ch,CURLOPT_COOKIEJAR, $CookieFile);
curl_setopt($ch,CURLOPT_COOKIEFILE, $CookieFile);//同时发送Cookie
curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $p);//提交查询信息
$s = curl_exec($ch);
curl_close($ch);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, http://www.bKjia.c0m);
curl_setopt($ch,CURLOPT_COOKIEFILE, $CookieFile);//同时发送Cookie
curl_setopt($ch,CURLOPT_COOKIEJAR, $CookieFile);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $p);//提交查询信息
$bs = curl_exec($ch);
echo $bs;//输出结果
curl_close($ch);
}else{
?>
