代理平台php
代理平台的PHP示例
requirements.php
```php
declare(strict_types=1);
namespace App;
use PsrHttpMessageResponseInterface;
use PsrHttpMessageServerRequestInterface;
use PsrLogLoggerInterface;
use ReactEventLoopFactory;
use ReactHttpServer;
use ReactSocketServer as SocketServer;
// PSR-15 middleware
use PsrHttpServerMiddlewareInterface;
use PsrHttpServerRequestHandlerInterface;
class Requirements implements MiddlewareInterface
{
public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
{
if (!isset($_SERVER['REMOTE_ADDR'])) {
throw new Exception('Remote server address not set.');
}
return $handler->handle($request);
}
}
return [
Requirements::class
];
```
proxy.php
```php
declare(strict_types=1);
namespace App;
use ReactEventLoopFactory;
use ReactHttpServer;
use ReactSocketServer as SocketServer;
$loop = Factory::create();
// Create the HTTP server
$server = new Server(
// The middleware is defined in requirements.php
[new MiddlewareFactory],
$loop
);
// Create the socket server and bind it to the loop
$socket = new SocketServer('127.0.0.1:8080', $loop);
$socket->on('connection', function ($connection) use ($server) {
$server->handle($connection);
});
$loop->run();
```
MiddlewareFactory.php
```php
declare(strict_types=1);
namespace App;
use PsrHttpMessageResponseInterface;
use PsrHttpMessageServerRequestInterface;
use PsrLogLoggerInterface;
// PSR-15 middleware
use PsrHttpServerMiddlewareInterface;
use PsrHttpServerRequestHandlerInterface;
class MiddlewareFactory implements MiddlewareInterface
{
private $logger;
public function __construct(LoggerInterface $logger)
{
$this->logger = $logger;
}
public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
{
$this->logger->info('Proxying request: ' . $request->getUri());
$response = $handler->handle($request);
$this->logger->info('Proxied response: ' . $response->getStatusCode());
return $response;
}
}
```
run.sh
```bash
!/bin/bash
composer install
php -S localhost:8080 -t public
```
Usage
Execute `run.sh` to start the proxy server. Then, you can send requests to `localhost:8080` and the proxy server will forward them to the remote server at `127.0.0.1:8080`.
Note: You may need to modify the IP address and port numbers in `proxy.php` to match your specific requirements.
