PHP 和旋转代理

Question

你们中有人尝试过使用轮换代理吗？这实施起来有多容易？它运作良好吗？请您的经验

PS：我看到像"how to make php script use a list of proxies" 这样的问题有很多缺点。你能在输入-1之前解释一下吗？

我去过那里，发现最好的解决方案是：

如果您没有专用服务器或至少没有 vps 并且有一点耐心，请不要费心阅读本文的其余部分...

1 - 从源代码安装 Squid 3.2（查看以下注释）
2 - 将 20 个左右的 ip 列表添加到 squid.conf（每月花费大约 25 美元）
3 - 使用新功能ACLrandom 轮换传出IP。

这样，您不需要在 php 脚本上轮换 ip 列表，而是连接到相同的 ip（例如：192.168.1.1:3129）但 可见的传出 ip (tcp_outgoing_address) 将根据随机设置轮换每个请求。

您需要使用 '-enable-http-violations' 编译 squid 3.2 以使其成为精英匿名代理。

分步安装：

yum -y groupinstall 'Development Tools'
yum -y install openssl-devel
wget http://www.squid-cache.org/Versions/v3/3.2/squid-3.2.13.tar.gz
tar -xvf squid-3.2.13.tar.gz
cd squid-3.2.13
./configure -prefix=/squid32 '--enable-removal-policies=heap,lru' '--enable-ssl' '--with-openssl' '--enable-linux-netfilter' '--with-pthreads' '--enable-ntlm-auth-helpers=SMB,fakeauth' '--enable-external-acl-helpers=ip_user,ldap_group,unix_group,wbinfo_group' '--enable-auth-basic' '--enable-auth-digest' '--enable-auth-negotiate' '--enable-auth-ntlm' '--with-winbind-auth-challenge' '--enable-useragent-log' '--enable-referer-log' '--disable-dependency-tracking' '--enable-cachemgr-hostname=localhost' '--enable-underscores' '--enable-build-info' '--enable-cache-digests' '--enable-ident-lookups' '--enable-follow-x-forwarded-for' '--enable-wccpv2' '--enable-fd-config' '--with-maxfd=16384' '-enable-http-violations'
make
make install

squid.conf 示例（在本例中位于 /squid32/etc/squid.conf）：

#this will be the ip and port where squid will run
http_port 5.5.5.5:33333 # change this ip and port ...

#Extra parameters on squid.conf to make **an elite proxy**

使用 squid 代理的 PHP CURL 请求示例：

$proxy = "1.1.1.1:33333";
$useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1";
$url = "https://api.ipify.org/";

$ch = curl_init();
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT,15);
curl_setopt($ch, CURLOPT_HTTP_VERSION,'CURL_HTTP_VERSION_1_1' );
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_PROXYUSERPWD,'USER:PASS');
curl_setopt($ch, CURLOPT_USERAGENT,$useragent);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,0);
$result=curl_exec ($ch);
curl_close ($ch);
echo $result

我发现这是轮换代理最可靠和最安全的方式，因为您不依赖第三方代理提供商，而且您的信息（密码、数据等）会更安全。 一开始可能听起来有点难以设置，但它会在你花费的每一秒内得到回报，GL :)

PHP Curl 支持很多代理命令。

CURLOPT_PROXYAUTH CURLOPT_PROXYPORT CURLOPT_PROXYTYPE CURLOPT_PROXY CURLOPT_PROXY_SERVICE_NAME CURLOPT_PROXYUSERPWD CURLOPT_PROXYHEADER CURLOPT_HTTPPROXYTUNNEL

查看更多信息：http://php.net/manual/en/function.curl-setopt.php

下面的简单示例。

$proxy      =   array();
$proxy[]    =   '1.2.3.4';
$proxy[]    =   '5.6.7.8';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXY, $proxy[array_rand($proxy)]);

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 15);


$result =   curl_exec($ch);
curl_close($ch);
