本文章來給各位同學介紹一下關于Php CURL模擬登陸論壇并采集數據實例,如果你對利用curl模擬登錄功能有興趣可進入參考。

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 基于表單的上傳、代理、cookies和用戶名+密碼的認證。

<?php

$discuz_url = 'http://www.49028c.com/';//論壇地址

$login_url = $discuz_url .'login.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(!emptyempty($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);

//這里的hash碼和登陸窗口的hash碼的正則不太一樣，這里的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(!emptyempty($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);
