php中用curl模拟登录discuz以及模拟发帖

$discuz_url = ‘http://localhost/klive/root/Discuz_X2.5_SC_GBK/’;//论坛地址
$login_url = $discuz_url .’member.php?mod=logging&action=login’;//登录页地址

$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'] = ‘admin’;
$post_fields['password'] = ‘admin’;
//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(‘/<inputs*type=”hidden”s*name=”formhash”s*value=”(.*?)”s*/>/i’, $contents,

$matches);
if(!empty($matches)) {
$formhash = $matches[1];
} else {
die(‘Not found the forumhash.’);
}

//POST数据，获取COOKIE,cookie文件放在网站的temp目录下
$cookie_file = tempnam(‘./temp’,'cookie’);

$ch = curl_init($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);

//取到了关键的cookie文件就可以带着cookie文件去模拟发帖,fid为论坛的栏目ID
$send_url = $discuz_url.”forum.php?mod=post&action=newthread&fid=2″;

$ch = curl_init($send_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
$contents = curl_exec($ch);
curl_close($ch);
//这里的hash码和登陆窗口的hash码的正则不太一样，这里的hidden多了一个id属性
preg_match(‘/<inputs*type=”hidden”s*name=”formhash”s*id=”formhash”s*value=”(.*?)”s*/>/i

//帖子内容

$post_data['topicsubmit'] = “yes”;
$post_data['extra'] = ”;
//帖子标签
$post_data['tags'] = ‘test’;
//帖子的hash码，这个非常关键！假如缺少这个hash码，discuz会警告你来路的页面不正确
$post_data['formhash']=$formhash;

$ch = curl_init($send_url);
curl_setopt($ch, CURLOPT_REFERER, $send_url);       //伪装REFERER
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);

curl_setopt($ch, CURLOPT_POST, 1);

//清理cookie文件
unlink($cookie_file);
