php如何实现代理下载文件
假如a.com/a.rar在天朝无法访问,如果写一个a.php脚本,放在海外服务器上,访问脚本路径b.com/a.php?url=http://a.com/a.rar
就可以实现文件下载了,请问这个a.php文件怎么写
回复讨论(解决方案)
你确定 绕着弯就可以翻墙了?

b.com/a.php?url=http://a.com/a.rar
如果文件不大可以这样写
$url = isset($_GET['url'])? $_GET['url'] : '';if($url){ $content = file_get_contents($url); if($content){ header('cache-control:public'); header('content-type:application/octet-stream'); header('content-disposition:attachment; filename='.basename($url)); echo $content; }}
要保证
1.天朝可以访问b.com
2.b.com可以访问a.com
可以使用 curl
$url = '传入的目标url';$ch = curl_init(); //初始化curl_setopt($ch, CURLOPT_URL, $url);//curl_setopt($ch, CURLOPT_REFERER, '某个来路url'); //伪造来路页面curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch, CURLOPT_WRITEFUNCTION, 'func');curl_exec($ch); //执行function func($ch, $str) { static $s = '@'; if($s) { $s = trim($str); if($s) header($s); }else echo $str; return strlen($str);}
b.com/a.php?url=http://a.com/a.rar
如果文件不大可以这样写
$url = isset($_GET['url'])? $_GET['url'] : '';if($url){ $content = file_get_contents($url); if($content){ header('cache-control:public'); header('content-type:application/octet-stream'); header('content-disposition:attachment; filename='.basename($url)); echo $content; }}
谢谢亲,如果能加入下载流量统计就好了
下载次数统计?
下载次数统计?
不是的。就是记录通过这个文件下载过的文件大小加起来数值把下载的功能,整合到方法里面,执行一次就往数据表加1
下载次数统计?
下??的文件大小加起??
echo strlen($content);
可以?取大小后??在???。

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,

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.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
