分享一个用了多年自动下载百度贴吧图片的PHP脚本

分享一个我经常用的下载百度贴吧的PHP脚本，贴吧有防爬机制，目前的做法是下载前设置cookie，然后下载完一张图片后停1-3秒，脚本基于phpspider，把脚本放到官方的demo目录，然后通过PHP命令行执行即可，代码如下：

[PHP] 纯文本查看 复制代码

ini_set("memory_limit", "10240M");
require_once __DIR__ . '/../autoloader.php';
use phpspider\core\phpspider;
use phpspider\core\requests;
use phpspider\core\selector;

shezhenba();

function shezhenba(){
	$pn = 0;
	$base_url = "https://tieba.baidu.com";
	do{
		
		$page = 'https://tieba.baidu.com/f?kw=%E8%88%8C%E8%AF%8A&ie=utf-8&pn='.$pn;
		print_r($page);
		echo "\n";

如果有大佬知道更好的防爬机制，请赐教。
