libcurl同時也支持HTTPS認證、HTTP POST、HTTP PUT、 FTP 上傳(這個也能通過PHP的FTP擴展完成)、HTTP 基於表單的上傳、代理、cookies和用戶名+密碼的認證。
php的curl真的是相當好用，網上一搜索相關文章都是關於curl模擬登陸的，很少人提供模擬discuz發貼的源碼。
復制代碼 代碼如下:
<?php
$discuz_url = 'http://127.0.0.1/discuz/';//論壇地址
$login_url = $discuz_url .'logging.php?action=login';//登錄頁地址
$post_fields = array();
//以下兩項不需要修改
$post_fields['loginfield'] = 'username';
$post_fields['loginsubmit'] = 'true';
//用戶名和密碼，必須填寫
$post_fields['username'] = 'tianxin';
$post_fields['password'] = '111111';
//安全提問
$post_fields['questionid'] = 0;
$post_fields['answer'] = '';
//@todo驗證碼
$post_fields['seccodeverify'] = '';
//獲取表單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('/<input\s*type="hidden"\s*name="formhash"\s*value="(.*?)"\s*\/>/i', $contents, $matches);
if(!empty($matches)) {
$formhash = $matches[1];
} else {
die('Not found the forumhash.');
}
//POST數據，獲取COOKIE,cookie文件放在網站的temp目錄下
$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);
//取到了關鍵的cookie文件就可以帶著cookie文件去模擬發帖,fid為論壇的欄目ID
$send_url = $discuz_url."post.php?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);
//這裡的hash碼和登陸窗口的hash碼的正則不太一樣，這裡的hidden多了一個id屬性
preg_match('/<input\s*type="hidden"\s*name="formhash"\s*id="formhash"\s*value="(.*?)"\s*\/>/i', $contents, $matches);
if(!empty($matches)) {
$formhash = $matches[1];
} else {
die('Not found the forumhash.');
}
$post_data = array();
//帖子標題
$post_data['subject'] = 'test2';
//帖子內容
$post_data['message'] = 'test2';
$post_data['topicsubmit'] = "yes";
$post_data['extra'] = '';
//帖子標簽
$post_data['tags'] = 'test';
//帖子的hash碼，這個非常關鍵！假如缺少這個hash碼，discuz會警告你來路的頁面不正確
$post_data['formhash']=$formhash;
$ch = curl_init($send_url);
curl_setopt($ch, CURLOPT_REFERER, $send_url); //偽裝REFERER
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
$contents = curl_exec($ch);
curl_close($ch);
//清理cookie文件
unlink($cookie_file);
?>
