如何使用PHP为Google云存储对象生成签名URL [英] How to generate Signed URL for google cloud storage objects using PHP

问题描述

我尝试使用的方法是使用openssl

The method i tried using was with openssl

$fp = fopen($key, 'r');  //open the PEM file
$priv_key = fread($fp,8192);
fclose($fp);
$pkeyid = openssl_get_privatekey($priv_key,"password");

openssl_sign($response["data_to_sign"], $signature, $pkeyid,'sha256');

$sign = base64_encode($signature)

这是在Google中为签名的URL生成签名的正确方法吗?

推荐答案

您可以尝试Google Cloud Storage PHP SDK，脚本的手动部分非常简单，代码看起来很干净.

You can try Google Cloud Storage PHP SDK, the manual part of scripting is quite simple and codes looks clean.

按照此页面将软件包安装到项目中 在Packagist上， 然后

Install package to your project by following this page on Packagist, then

function getSignedGcsUrl($objPath/* which is your target object path */, $duration = 50) 
{
    $storageClient = new StorageClient([
        'projectId' => /* your gcp projectId here */,
        'keyFilePath' => /* your gcp keyFilePath here */,
    ]);
    $bucket = $storageClient->bucket($objPath);
    $object = $bucket->object();
    $url = $object->signedUrl(new \DateTime('+ ' . $duration . ' seconds'));
    return $url;
}

laravel-google-cloud-storage(用于Laravel)

通过遵循以下页面来安装和配置superbalist/laravel-google-cloud-storage: 在Github上， 然后

laravel-google-cloud-storage (for Laravel)

Install and configurate superbalist/laravel-google-cloud-storage by following this page: on Github, then

public static function getSignedGcsUrl($objPath, $duration = 50)
{
    return Storage::disk('gcs'/* following your filesystem configuration */)
        ->getAdapter()
        ->getBucket()
        ->object($objPath)
        ->signedUrl(new \DateTime('+ ' . $duration . ' seconds'));
}
