PHP和旋轉代理

Question

有沒有人嘗試過使用旋轉代理？這是多麼容易實現？它工作正常嗎？你的經驗請

PS：我看到像"how to make php script use a list of proxies"這樣的問題收集了很多的缺點。你可以解釋這個之前把-1？

我一直在那裏，發現最好的解決辦法是：

如果您沒有一個專門的服務器或至少一個VPS和一點點耐心，也懶得去閱讀後的休息...

1 - 從源代碼安裝魷魚3.2（檢查下面的註釋）
2 - 將20個左右的ip列表添加到squid.conf中（成本約25美元）
3 - 使用新功能ACLrandom來旋轉傳出IP。

這樣你就不需要轉動你的PHP腳本知識產權的名單，相反，你會被連接到相同的IP（例如：192.168.1.1:3129），但可見傳出IP（ tcp_outgoing_address）將基於隨機設置對每個請求進行旋轉。

您需要使用'-enable-http-violations'編譯squid 3.2以使其成爲精英匿名代理。

步驟通過步驟安裝：

yum -y groupinstall 'Development Tools' 
yum -y install openssl-devel 
mkdir /meus 
cd /meus 
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 

樣品的squid.conf（位於在這種情況下/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

示例PHP CURL請求使用魷魚代理：

$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

我發現這是最可靠和最安全的方式來旋轉代理，因爲你不依賴於第三方代理提供商和你的信息（密碼，數據等）會更安全。 這可能聽起來有點難以設置，但它會支付每一秒，你花了，GL :)
