例子一: 基本例子

基本例子 ﹤?php
// 初始化一个 cURL 对象
$curl = curl_init();

// 设置你需要抓取的URL
curl_setopt($curl, CURLOPT_URL, 'http://www.cmx8.cn');

// 设置header
curl_setopt($curl, CURLOPT_HEADER, 1);

// 设置cURL 参数,要求结果保存到字符串中还是输出到屏幕上。
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

// 运行cURL,请求网页
$data = curl_exec($curl);

// 关闭URL请求
curl_close($curl);

// 显示获得的数据
var_dump($data);

?>

例子二: POST数据

sendSMS.php,其可以接受两个表单域,一个是电话号码,一个是短信内容。

POST数据 ﹤?php
$phoneNumber  = '13812345678';
$message = 'This message was generated by curl and  php';
$curlPost = 'pNUMBER=' . urlencode($phoneNumber) .  '&MESSAGE=' . urlencode($message) . '&SUBMIT=Send';
$ch =  curl_init();
curl_setopt($ch, CURLOPT_URL,  'http://www.lxvoip.com/sendSMS.php');
curl_setopt($ch,  CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch,  CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
$data  = curl_exec();
curl_close($ch);
?﹥

例子三:使用代理服务器

使用代理服务器 ﹤?php 
$ch =  curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.cmx8.cn');
curl_setopt($ch,  CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch,  CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($ch, CURLOPT_PROXY,  'proxy.lxvoip.com:1080');
curl_setopt($ch, CURLOPT_PROXYUSERPWD,  'user:password');
$data = curl_exec();
curl_close($ch);
?﹥

例子四: 模拟登录

Curl 模拟登录 discuz 程序,适合DZ7.0,将username改成你的用户名,userpass改成你的密码就可以了.

Curl 模拟登录 discuz 程序 /**
* Curl 模拟登录 discuz 程序
* 尚未实现开启验证码的的论坛登录功能
*/

!extension_loaded('curl') && die('The curl extension is not loaded.');

$discuz_url = 'http://www.lxvoip.com';//论坛地址
$login_url = $discuz_url .'/logging.php?action=login';//登录页地址
$get_url = $discuz_url .'/my.php?item=threads'; //我的帖子

$post_fields = array();
//以下两项不需要修改
$post_fields['loginfield'] = 'username';
$post_fields['loginsubmit'] = 'true';
//用户名和密码,必须填写
$post_fields['username'] = 'lxvoip';
$post_fields['password'] = '88888888';
//安全提问
$post_fields['questionid'] = 0;
$post_fields['answer'] = '';
//@todo验证码
$post_fields['seccodeverify'] = '';

//获取表单FORMHASH
$ch = curl_init($login_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$contents = curl_exec($ch);
curl_close($ch);
preg_match('//i', $contents, $matches);
if(!empty($matches)) {
$formhash = $matches[1];
} else {
die('Not found the forumhash.');
}

//POST数据,获取COOKIE
$cookie_file = dirname(__FILE__) . '/cookie.txt';
//$cookie_file = tempnam('/tmp');
$ch = curl_init($login_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
curl_exec($ch);
curl_close($ch);

//带着上面得到的COOKIE获取需要登录后才能查看的页面内容
$ch = curl_init($get_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
$contents = curl_exec($ch);
curl_close($ch);

var_dump($contents);
?>
