[PHP]Reverse Proxy反向代理

[PHP]Reverse Proxy反向代理

参考: ​​url,但是显示的是A url,这样就需要进行反向代理

以下是根据上文参考改良而成,传入pdf参数

url = $url; $this->proxy_url = $proxy_url; // Parse all the parameters for the URL if (isset($_SERVER['PATH_INFO'])) { $proxy_url .= $_SERVER['PATH_INFO']; } else { $proxy_url .= '/'; } if ($_SERVER['QUERY_STRING'] !== '') { $proxy_url .= "?{$_SERVER['QUERY_STRING']}"; } $translated_url = $proxy_url. $pdf; $this->curl_handler = curl_init($translated_url); logger('translated_url: '. $translated_url); logger('curl_handler: '. $this->curl_handler); // Set various options $this->setCurlOption(CURLOPT_RETURNTRANSFER, true); $this->setCurlOption(CURLOPT_BINARYTRANSFER, true); // For images, etc. $this->setCurlOption(CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); $this->setCurlOption(CURLOPT_WRITEFUNCTION, array($this,'readResponse')); $this->setCurlOption(CURLOPT_HEADERFUNCTION, array($this,'readHeaders')); // Process post data. if (count($_POST)) { logger('in post method'); // Empty the post data $post=array(); // Set the post data $this->setCurlOption(CURLOPT_POST, true); // Encode and form the post data foreach ($_POST as $key => $value) { $post[] = urlencode($key)."=".urlencode($value); } $this->setCurlOption(CURLOPT_POSTFIELDS, implode('&', $post)); unset($post); } elseif ($_SERVER['REQUEST_METHOD'] !== 'GET') { // Default request method is 'get' logger('in get method'); // Set the request method $this->setCurlOption(CURLOPT_CUSTOMREQUEST, $_SERVER['REQUEST_METHOD']); } } // Executes the proxy. public function execute() { logger('start to execute'); curl_exec($this->curl_handler); } // Get the information about the request. // Should not be called before exec. public function getCurlInfo() { return curl_getinfo($this->curl_handler); } // Sets a curl option. public function setCurlOption($option, $value) { curl_setopt($this->curl_handler, $option, $value); } protected function readHeaders(&$cu, $string): int { $length = strlen($string); if (preg_match(',^Location:,', $string)) { $string = str_replace($this->proxy_url, $this->url, $string); } header($string); return $length; } protected function readResponse(&$cu, $string): int { $length = strlen($string); echo $string; return $length; }}

把以上代码复制进去项目,然后通过以下执行

class ReverseProxyController extends Controller{ /** * @var ProxyHandler */ private $proxy; /** * ReverseProxyController constructor. * @param ProxyHandler $proxy */ public function __construct(ProxyHandler $proxy) { $this->proxy = $proxy; } public function uploadPdf(Request $request, $pdf) { $uploadUrl = config('app.reverse_proxy'); $nativeUrl = config('app.url').'/upload/public/doc/' . $pdf; $this->proxy->begin($nativeUrl, $uploadUrl, $pdf); $this->proxy->execute(); }
