PHP爬虫程序中添加代理信息代码示例

<?php // 要访问的目标页面 $url = "http://httpbin.org/ip"; $urls = "https://httpbin.org/ip"; // 代理服务器 define("PROXY_SERVER", "tcp://t.16yun.cn:31111"); // 隧道身份信息 define("PROXY_USER", "16YUN123"); define("PROXY_PASS", "123456"); $proxyAuth = base64_encode(PROXY_USER . ":" . PROXY_PASS); // 设置 Proxy tunnel $tunnel = rand(1,10000); $headers = implode("\r\n", [ "Proxy-Authorization: Basic {$proxyAuth}", "Proxy-Tunnel: ${tunnel}", ]); $sniServer = parse_url($urls, PHP_URL_HOST); $options = [ "http" => [ "proxy" => PROXY_SERVER, "header" => $headers, "method" => "GET", 'request_fulluri' => true, ], 'ssl' => array( 'SNI_enabled' => true, // Disable SNI for https over http proxies 'SNI_server_name' => $sniServer ) ]; print($url); $context = stream_context_create($options); $result = file_get_contents($url, false, $context); var_dump($result); // 访问 HTTPS 页面 print($urls); $context = stream_context_create($options); $result = file_get_contents($urls, false, $context); var_dump($result); ?>
