php - 从 URL 上传内容

Question

我正在为某人构建一个视频转换器。我只需要知道，当有人将 URL 粘贴到视频时，我如何将该视频下载到服务器？这里的任何东西都会有所帮助。

Answer 1

如果您想在 php 中使用它，请尝试 curl：

function curl_download($Url){

    // is cURL installed yet?
    if (!function_exists('curl_init')){
        die('Sorry cURL is not installed!');
    }

    // OK cool - then let's create a new cURL resource handle
    $ch = curl_init();

    // Now set some options (most are optional)

    // Set URL to download
    curl_setopt($ch, CURLOPT_URL, $Url);

    // Set a referer
    curl_setopt($ch, CURLOPT_REFERER, "http://www.example.org/yay.htm");

    // User agent
    curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");

    // Include header in result? (0 = yes, 1 = no)
    curl_setopt($ch, CURLOPT_HEADER, 0);

    // Should cURL return or print out the data? (true = return, false = print)
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Timeout in seconds
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);

    // Download the given URL, and return output
    $output = curl_exec($ch);

    // Close the cURL resource, and free system resources
    curl_close($ch);

    return $output;
}

什么样的视频？如果您有实际的视频源，那么这是您最好的选择： download-file-to-server-from-url

如果您不这样做，那么您很可能必须编写自己的视频开膛手，例如http://keepvid.com
