如何使用PHP服务端代理抓取网页内容_PHP

Jun 01, 2016 pm 12:21 PM

最近公司暂时断开外网,只开放公司自己所有的站点允许访问,说实在的,做WEB开发的断网,真是让人哭笑不得......

由于需要查找资料,只好简单写了一个PHP的服务端代理页面来用一下!

简单框架页面:

以下为引用的内容:
















PHP代理页面:

以下为引用的内容:

//使用Snoopy的抓页功能
include "Snoopy.class.php";
//目标URL
$url = $_REQUEST['targeturl'];
//将所有传递过来的参数列出来
$par = array();
$GetPost = array_merge($_POST,$_GET);
foreach($GetPost As $Key=>$Value){
 if($Key!='targeturl'){
  $Value = str_replace("%25","%",$Value);
  array_push($par,($Key . "=" . $Value));
 }
}
//判断目标URL是否带有?(即是否带有参数)
$cc = strpos($url,"?") ? "&" : "?";
//重组URL
$geturl = !$par ? $url : $url.$cc.implode("&",$par);
//抓取重组后的URL页面内容
$snoopy = new Snoopy;
$snoopy->fetch($geturl);
//替换目标内容中脚本里有可能替换父窗口地址的代码
$org = str_replace("top.location","top.title",$snoopy->results);
//尝试转换目标内容编码到UTF-8
$opt = iconv("gbk","utf-8",$org);
//判断目标内容编码为GBK或UTF-8
$ec = strlen($opt)?"gbk":"utf-8";

?>

//脚本放在输出内容前,避免内容中可能出现脚本错误而导致我们要做的事情被废掉
//输出抓到的目标页面内容

在这个小作品中,我编写了一个重要的JavaScript函数easyUTF8,它可以很方便地在JavaScript脚本中将GBK编码的内容转换为UTF-8编码。

我们还处理了一下表单中添加项目的兼容问题,注意看createIPH函数,在IE中创建的表单项内容,在指定name和value时可能会出现我们不希望的结果,这在DHTML手册中已经有过描述了。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
