php - 更快的 Rackspace 云上传

Question

我已经使用 Rackspace API 将文件上传到 RackSpace 云。但是这种方法似乎有点慢。是否有更好或更快的方式将文件上传到云端（curl、http 适配器等）？

我目前正在使用 PHP 上传并使用提供的 API。

Answer 1

这是我的解决方案如何使其快速：

我正在使用下面的简单PHP脚本仅上传丢失的文件。多亏了它，我只需单击几秒钟即可完成。

PHP 源代码：

function UploadMissingFilesToRackFileCDN($file_paths_to_upload, $b_force_upload = false)
{
    include_once("cloudfiles.php");

    // Connect to Rackspace
    $username = cloudfile_username; // username
    echo "Connecting to CDN..." . date("H:i:s") . "<br>"; ob_flush();
    $key = cloudfile_api_key; // api key
    $auth = new CF_Authentication($username, $key);
    $auth->authenticate();
    $conn = new CF_Connection($auth);
    echo "&nbsp;&nbsp;&nbsp;&nbsp;Connected!" . date("H:i:s") . "<br>"; ob_flush();

    // Get the container we want to use
    $container_name = 'vladonai';//'test_container';
    echo "Obtaining container $container_name..." . date("H:i:s") . "<br>"; ob_flush();
    $container = $conn->get_container($container_name);
    echo "&nbsp;&nbsp;&nbsp;&nbsp;The container is obtained." . date("H:i:s") . "<br>"; ob_flush();

    if (!$b_force_upload)
    {
        echo "Receiving container objects list..." . date("H:i:s") . "<br>"; ob_flush();
        $existing_object_names = $container->list_objects();
        $existing_files_count = count($existing_object_names);
        echo "&nbsp;&nbsp;&nbsp;&nbsp;Objects list obtained: $existing_files_count." . date("H:i:s") . "<br>"; ob_flush();
        $existing_object_names_text .= "\r\n";
        foreach ($existing_object_names as $obj_name)
        {
            $existing_object_names_text .= $obj_name . "\r\n";
        } 
    }

    // upload files to Rackspace
    $uploaded_file_n = 0;
    $skipped_file_n = 0;
    $errors_count = 0;
    foreach ($file_paths_to_upload as $localfile_path => $file_info)
    {
        $filename = basename($localfile_path);

        if (!file_exists($localfile_path))
        {
            echo "<font color=red>Error! File $localfile_path doesn't exists!</font>" . date("H:i:s") . "<br>"; ob_flush();
            $errors_count ++;
        } else
        if (is_dir($localfile_path))
        {
            //simply skip it
        } else
        if (strpos($existing_object_names_text, "\r\n" . $filename . "\r\n") !== false)
        {
            //file is already uploaded to CDN (at least file name is present there). Would be good to have date/size checked, but CDN api has no such feature
            //echo "<font color=gray>Skipped file $localfile_path - it already exists!</font><br>"; ob_flush();
            $skipped_file_n ++;

            catch (Exception $e)
            {
                echo "<font color=red>Error! Caught exception: ",  $e->getMessage(), " on uploading file <strong>$localfile_path</strong>!</font>" . date("H:i:s") . "<br>"; ob_flush();
                $errors_count ++;
            }
        }

    //  if ($uploaded_file_n >= 10)
    //      break;
    }
    echo "Done! $uploaded_file_n files uploaded. Disconnecting :)" . date("H:i:s") . "<br>"; ob_flush();

    if ($errors_count > 0)
