PHP爬蟲語言配置億牛雲爬蟲代理的方案

// 要訪問的目標頁面
$url = "http://httpbin.org/ip";
$urls = "https://httpbin.org/ip";

    // 代理服務器
    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);

    // 設置 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);

    // 訪問 HTTPS 頁面
    print($urls);
