Question

public function download_file($link='https://apkpure.co/apk/com.ezfun.p1767.dns_gp1/00b97d3d32a4f8e6cbecff7da5a4af41/1.0/0dfa1365e8e1c70bf2dcf391350a7a77/', $filename='com.ezfun.p1767.dns_gp1_1.0'){

    $extension = 'apk';

    $mime = 'application/octet-stream';

    if( strstr( $_SERVER['HTTP_USER_AGENT'], "MSIE" ) ) {
        header( 'Content-Type: "'.$mime.'"' );
        header( 'Content-Disposition: attachment; filename='.$filename.'.'.$extension );
        header( 'Expires: 0' );
        header( 'Cache-Control: must-revalidate, post-check=0, pre-check=0' );
        header( "Content-Transfer-Encoding: binary" );
        header( 'Pragma: public' );
    } else {
        header( "Pragma: public" );
        header( "Expires: 0" );
        header( "Cache-Control: must-revalidate, post-check=0, pre-check=0" );
        header( "Cache-Control: private", false );
        header( "Content-Type: ".$mime, true, 200 );
        header( 'Content-Disposition: attachment; filename='.$filename.'.'.$extension);
        header( "Content-Transfer-Encoding: binary" );
    }

    readfile( $link );

}

我需要readfile下载一个apk文件，但是我无法直接访问这个网站，我需要一个代理。

任何建议？

使用此代码使用curl代理下载文件：

function download_file($url, $filename) {

    $proxy = 'Proxy IP ADDRess'; //128.114.63.15:3128
    $handle = curl_init();
    curl_setopt($handle, CURLOPT_URL, $url);
    curl_setopt($handle, CURLOPT_HTTPPROXYTUNNEL, 0);
    curl_setopt($handle, CURLOPT_PROXY, $proxy);
    curl_setopt($handle, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($handle, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, 0);
    $response = curl_exec($handle);
    curl_close($handle);
    header('Expires: 0'); // no cache
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Last-Modified: ' . gmdate('D, d M Y H:i:s', time()) . ' GMT');
    header('Cache-Control: private', false);
    header('Content-Type: application/force-download');
    header('Content-Disposition: attachment; filename="' . $filename . '.apk"');
    header('Content-Transfer-Encoding: binary');
    header('Content-Length: ' . strlen($response)); // provide file size
    header('Connection: close');
    echo $response;
}

我发现readfile（）不支持绑定代理，如果需要，必须找到一种在base中设置代理的方法。有人说使用apache，但我没有做过。

最后另一个函数file_get_contents（）解决了我的问题。

这是我的代码：

public function download_file($link='https://apkpure.co/apk/com.ezfun.p1767.dns_gp1/00b97d3d32a4f8e6cbecff7da5a4af41/1.0/0dfa1365e8e1c70bf2dcf391350a7a77/', $filename='com.ezfun.p1767.dns_gp1_1.0'){

    $aContext = array(
        'http' => array(
            'proxy' => 'tcp://192.168.10.3:18118',
            'request_fulluri' => true,
        ),
    );
    $cxContext = stream_context_create($aContext);

    $sFile = file_get_contents("https://apkpure.co/apk/com.wepie.snakeoff/6fbde5c9d65e72d4d014f9bf654bfe47/2.0/984e0be4d6a84965544692bc30487837/", False, $cxContext);

    $path = file_put_contents(public_path().'/application.snakeoff.apk', $sFile);

    echo $path;

}

file_put_content将返回写入文件的字节数，如果失败则返回FALSE。

代理后面的readfile（）？
