php設置代理

Ⅰ php代碼如何放行代理伺服器IP

<?php
//授權IP
$ips=['119.29.29.29','8.8.8.8'];
//代理IP直接退出
empty($_SERVER['HTTP_VIA'])orexit('AccessDenied');
//防止快速刷新
session_start();
$seconds='3';//時間段[秒]
$refresh='5';//刷新次數
//設置監控變數
$cur_time=time();
if(isset($_SESSION['last_time'])){
$_SESSION['refresh_times']+=1;
}else{
$_SESSION['refresh_times']=1;
$_SESSION['last_time']=$cur_time;
}
//處理監控結果
if($cur_time-$_SESSION['last_time']<$seconds){
if($_SESSION['refresh_times']>=$refresh&&!in_array($getIP,$ips)){
//跳轉至攻擊者伺服器地址
header(sprintf('Location:%s','
));
exit('AccessDenied');
}
}else{
$_SESSION['refresh_times']=0;
$_SESSION['last_time']=$cur_time;
}

functiongetIP(){
if(getenv('HTTP_CLIENT_IP')){
$ip=getenv('HTTP_CLIENT_IP');
}elseif(getenv('HTTP_X_FORWARDED_FOR')){
$ip=getenv('HTTP_X_FORWARDED_FOR');
}elseif(getenv('HTTP_X_FORWARDED')){
$ip=getenv('HTTP_X_FORWARDED');
}elseif(getenv('HTTP_FORWARDED_FOR')){
$ip=getenv('HTTP_FORWARDED_FOR');

}elseif(getenv('HTTP_FORWARDED')){
$ip=getenv('HTTP_FORWARDED');
}else{
$ip=$_SERVER['REMOTE_ADDR'];
}

return$ip;
}

Ⅱ PHP使用代理方法獲取遠程網頁的代碼.

functioncurl_string($url,$user_agent,$proxy){

$ch=curl_init();
curl_setopt($ch,CURLOPT_PROXY,$proxy);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_USERAGENT,$user_agent);
curl_setopt($ch,CURLOPT_COOKIEJAR,"c:cookie.txt");
curl_setopt($ch,CURLOPT_HEADER,1);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch,CURLOPT_TIMEOUT,120);
$result=curl_exec($ch);
curl_close($ch);
return$result;

}

$url_page="http://www..com";
$user_agent="Mozilla/4.0";
$proxy="http://192.11.222.124:8000";//這里是http代理
$string=curl_string($url_page,$user_agent,$proxy);
echo$string;

Ⅲ php利用Nginx如何實現反向代理

• 我們要首先准備好環境，我准備好了nginx環境和apache的環境

  

Ⅳ 有沒有辦法實現PHP代理抓取網頁內容

可以呀。

用snoopy的類，網上有snoopy.class.php，你自行網路查找。
snoopy的類可以設置$proxy_host參數，設置代理主機，$proxy_port是代理主機埠。你下載一個下來，網上的教程很多，看看應該明白。

至於調用proxy.txt，輪換ip的問題，我覺得可用代理不是很多的話，可以設置成隨機選擇代理就好了。你採集的那個網站記錄的是你代理伺服器的ip

Ⅳ 如何給phpstorm設置代理

PHPStorm的配置分為2大類：項目配置和IDE配置。
項目配置（設置），主要是配置具體項目。
IDE 配置（設置），通用的設置會應用到所有的項目上。
項目配置
每個項目的配置存儲在項目所在目錄的 .idea 文件夾中，並以XML格式保存配置。如果你設置的是 「default project settings 默認項目設置」，那麼這個默認設置將會自動應用到下一個最新創建的項目上。
IDE 配置
IDE 配置存儲在PHPStorm指定的獨立文件夾中，各個平台不同，配置的文件夾存放位置也不同。存放目錄由PHPStorm名稱和版本組成。
例如：
Windows
<User home>.WebIdeXXconfig 存放用戶指定的設置。
<User home>.WebIdeXXsystem 存放PHPStorm 緩存文件。
<User home> 在 WindowsXP 是指 C:Documents and Settings<User name>; 在Windows 7 以上是指 C:Users<User name>
Linux

~/.WebIdeXX/config 存放用戶指定的設置
~/.WebIdeXX/system 存放PHPStorm 緩存文件。
Mac OS

~/Library/Application Support/WebIdeXX 存放PHPStorm插件。
~/Library/Preferences/WebIdeXX 存放PHPStorm配置文件。
~/Library/Caches/WebIdeXX 存放PHPStorm緩存，歷史記錄等。
~/Library/Logs/WebIdeXX 存放PHPStorm日誌。
配置目錄下存在多個子目錄，並且都以XML的文件形式來存放配置。你可以分享這些XML配置文件給別人，例如快捷鍵配置，顏色方案等等，只需將這些XML文件拷貝到PHPStorm安裝的具體目錄，覆蓋之前請確保Phpstorm是關閉的，不然很可能被正在運行的PhpStorm配置時覆蓋。從而達不到效果。

下面這個列表包含了配置文件夾下的子文件夾的意義。

目錄名稱 用戶配置
codestyles 代碼風格配置
colors 編輯器顏色，字體等自定義方案的配置
filetypes 用戶自定義的文件類型配置
inspection 代碼檢查配置
keymaps PhpStorm自定義快捷鍵的配置
options 各個參數的配置，例如：功能使用情況統計
templates 用戶自定義的代碼模版
tools 外部工具的配置
shelf shelved配置
PhpStorm 的配置，系統，插件目錄可以被修改，進入PhpStorm安裝目錄binidea.properties 文件。
您將需要調整以下參數：
idea.config.path

idea.system.path

idea.plugins.path

Ⅵ PHP實現代理IP

「代理IP」現在有很多種的，就是軟體改IP的。
軟體上有很多IP點提供給使用者切換的
在電腦上安裝IP轉換器，
在IP軟體上選擇不同的IP點連接就可以了的。
推薦軟體。可找到類似軟體的。
全國大多數城市（數百萬IP點任意切換）
希望可以幫到你。多少電腦多可以使用的。

Ⅶ 怎麼樣用php語言實現通過proxy代理伺服器訪問網站呢

function curl_string ($url,$timeout = 3,$proxy=1){
$ua = array('Mozilla','Opera','Microsoft Internet Explorer','ia_archiver');
$op = array('Windows','Windows XP','Linux','Windows NT','Windows 2000','OSX');
$agent = $ua[rand(0,3)].'/'.rand(1,8).'.'.rand(0,9).' ('.$op[rand(0,5)].' '.rand(1,7).'.'.rand(0,9).'; en-US;)';
Tor 地址與埠
$tor = 'http://www.aimilife.com'; //這里是你的代理伺服器
連接超時設置
$timeout = 3;
$ack = curl_init();
if($proxy)
{
curl_setopt($ack, CURLOPT_PROXY, $tor);
}
curl_setopt($ack, CURLOPT_URL, $url);
curl_setopt($ack, CURLOPT_HEADER, 0);
curl_setopt($ack, CURLOPT_USERAGENT, $agent);
curl_setopt($ack, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ack, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ack, CURLOPT_TIMEOUT, $timeout);
$result = curl_exec($ack);
curl_close($ack);
return $result;

}

Ⅷ php爬蟲如何切換代理

618代理IP，自建機房,HTTP代理,爬蟲代理,價格超低。多種時長選擇,滿足不同用戶的需求,超高可用率,支持HTTP,HTTPS,SOCKS5等協議。

Ⅸ php如何用代理訪問網站 求代碼

CURL 就可以啊！你的先自己開個http代理 。或者網路找一些http代理

然後在curl裡面設置http代理就可以了。

functioncurl_string($url,$user_agent,$proxy){
$ch=curl_init();
curl_setopt($ch,CURLOPT_PROXY,$proxy);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_USERAGENT,$user_agent);
curl_setopt($ch,CURLOPT_COOKIEJAR,"c:cookie.txt");//可刪除
curl_setopt($ch,CURLOPT_HEADER,1);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch,CURLOPT_TIMEOUT,120);
$result=curl_exec($ch);
curl_close($ch);
return$result;

}
$content="http://www.google.com";$user_agent="Mozilla/4.0";$proxy="http://192.11.222.124:8000";

Ⅹ 使用thinkphp 怎麼實現反向代理

改自PHP Reverse Proxy PRP，修改了原版中的一些錯誤，支持了文件上傳以及上傳文件類型識別，支持指定IP，自適應SAE環境。
使用方法
?123456789 <?php $proxy=new PhpReverseProxy(); $proxy->port="8080"; $proxy->host="ww"; //$proxy->ip="1.1.1.1"; $proxy->forward_path=""; $proxy->connect(); $proxy->output(); ?>
