如何通过脚本将单个文件传输到谷歌云存储

Question

因此，我将首先说明我的老板要求我在没有 Google 存储桶实例或 Google Cloud Platform 的 .json 密钥文件的情况下设置 Google Cloud Storage 备份流程。基本上，我正在编写一个脚本来批量处理 Google Cloud Platform 机器的 Linux 和 Windows 实例，以获取将每天存储的备份文件，将其发送到 Google Cloud Storage，然后从系统（以便备份文件不占用实例空间）。由于所有这些对我来说都是相对较新的，我希望获得一些关于此过程是否需要密钥（.json 私钥）以及如何包含它的建议；显然，我没有密钥，但我想在我们设置好之前添加一个占位符。

我发现 Google 的文档很有帮助，但有点让人不知所措。这是我用来参考的链接：https://cloud.google.com/storage/docs/uploading-objects#storage-upload-object-code-sample

这是我的代码：

    <?php
require_once 'vendor/autoload.php';
use Google\Cloud\Storage\StorageClient;

// Set up storage client with keyfilepath or .json key necessary?


// Set the parameters for Google cloud bucket name, filename, and path to file.
$bucketName = "fishbowl-storage";
$fileNameA = "backup_filename";
$fileNameB = "quickbook_filename";

$dataBackupSource = "";
$dataQBBackupSource = "";

// Set the function that will upload the file to google Cloud Storage.
function upload_object($bucketName, $fileName, $source)
{

    // Create the storage client and store the file in the cloud.
    $storage = new StorageClient();
    $file = fopen($source, 'r');
    $bucket = $storage->bucket($bucketName);
    $file = $bucket->upload($file, [
        'name' => $fileName
    ]);
    // Print the success message to the user.
    printf('Uploaded %s to gs://%s/%s' . PHP_EOL, basename($source), $bucketName, $fileName);

}


// Check the OS to determine whether Linux or Windows.
if(php_uname('s') == "Linux"){

    // Set the file path to grab back up.
    $dataBackupSource = "../Fishbowl/backup";
    $dataQBBackupSource = "../Fishbowl/otherbackup";

    // Use try/catch statement to catch issues with private key.
    try{

        // run the function to place both backup files in the Google Cloud Storage Bucket instance.
        upload_object($bucketName, $fileNameA, $dataBackupSource);
        upload_object($bucketName, $fileNameB, $dataQBBackupSource);

        // Delete the old file stored in the path.
        if(!unlink($fileNameA)){
            print ("The file cannot be deleteted or isn't present in this directory...");
        }
        else{
            print ("The file " . $fileNameA . " has been deleted.");
        }
    } 
    catch (Exception $e){
        print "This process failed for the following reason: " . $e;
        return false;
    }
}
else if(php_uname('s') == "Windows NT"){

    // Set the file path to grab back up.
    $dataBackupSource = "../Fishbowl/backup";
    $dataQBBackupSource = "../Fishbowl/otherbackup";

    // Use try/catch statement to catch issues with private key.
    try{

        // run the function to place both backup files in the Google Cloud Storage Bucket instance.
        upload_object($bucketName, $fileNameA, $dataBackupSource);
        upload_object($bucketName, $fileNameB, $dataQBBackupSource);

        // Delete the old file stored in the path.
        if(!unlink($fileNameA)){
            print ("The file cannot be deleteted or isn't present in this directory...");
        }
        else{
            print ("The file " . $fileNameA . " has been deleted.");
        }
    } 
    catch (Exception $e){
        print "This process failed for the following reason: " . $e;
        return false;
    }
}
else{
    print "The operating system has another name...";
}

?>

TLDR：我是否需要在我的脚本中包含 JSON 密钥才能将文件传递到 Google 云存储，如果需要，我应该把它放在哪里？

Answer 1

我认为这就是您正在寻找的documentation。基本上，您需要为 Google Cloud Storage API 使用 Cloud Client Libraries。这些是您需要遵循的步骤

1.安装客户端库

作曲家需要 google/cloud-storage

2.设置身份验证。在这个step 中，您将创建服务帐户和密钥

设置环境变量后，在使用 Google Cloud 客户端库时，您无需在代码中显式指定您的凭据，正如提到的 here

3.使用客户端库。在这种情况下，你想upload a file。

use Google\Cloud\Storage\StorageClient;

/**
 * Upload a file.
 *
 * @param string $bucketName the name of your Google Cloud bucket.
 * @param string $objectName the name of the object.
 * @param string $source the path to the file to upload.
 *
 * @return Psr\Http\Message\StreamInterface
 */
function upload_object($bucketName, $objectName, $source)
{
    $storage = new StorageClient();
    $file = fopen($source, 'r');
    $bucket = $storage->bucket($bucketName);
    $object = $bucket->upload($file, [
        'name' => $objectName
    ]);
    printf('Uploaded %s to gs://%s/%s' . PHP_EOL, basename($source), 
$bucketName, $objectName);
}
