本文章来给各位同学介绍一下关于Php CURL模拟登陆论坛并采集数据实例,如果你对利用curl模拟登录功能有兴趣可进入参考。

libcurl同时也支持HTTPS认证、HTTP POST、HTTP PUT、 FTP 上传(这个也能通过PHP的FTP扩展完成)、HTTP 基于表单的上传、代理、cookies和用户名+密码的认证。

									<?php 

									$discuz_url = 'http://www.zzvips.com/';//论坛地址 

									$login_url = $discuz_url .'login.php?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'] = 'tianxin'; 

									$post_fields['password'] = '111111'; 

									//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('/<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_RETURNTRANSFER, 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."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); 

									//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('/<input\s*type="hidden"\s*name="formhash"\s*id="formhash"\s*value="(.*?)"\s*\/>/i', $contents, $matches);

									$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_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);
