为了从 App Engine 外部或外部服务器将文件上传到 Google Cloud Storage,您必须安装您使用的编程语言的客户端库。
Step 1:
从以下 URL 创建 Google 服务帐户密钥并下载 json 文件,其中包含您从客户端 PC 登录所需的所有凭据信息。
https://console.cloud.google.com/apis/credentials
Step 2:
PHP:
Install composer require google/cloud-storage
<?php
# Includes the autoloader for libraries installed with composer
require __DIR__ . '/vendor/autoload.php';
use Google\Cloud\Storage\StorageClient;
use google\appengine\api\cloud_storage\CloudStorageTools;
# Your Google Cloud Platform project ID
$projectId = 'your_project_id';
# Instantiates a client
$storage = new StorageClient([
'projectId' => $projectId,
'keyFilePath' => 'service_account_key_json_file.json'
]);
# The name for the bucket
$bucket = $storage->bucket('bucket_name');
foreach ($bucket->objects() as $object) {
echo "https://storage.googleapis.com/".$bucket->name()."/".$object->name().'<br>';
}
if(isset($_POST['submit'])) {
$file = file_get_contents($_FILES['file']['tmp_name']);
$objectName = $_FILES["file"]["name"];
$object = $bucket->upload($file, [
'name' => $objectName
]);
echo "https://storage.googleapis.com/".$bucket->name()."/".$objectname;
}
?>
JavaScript (NodeJs):
Install npm install --save @google-cloud/storage
'use strict';
const express = require('express');
const formidable = require('formidable');
const fs = require('fs');
const path = require('path');
const { Storage } = require('@google-cloud/storage');
const Multer = require('multer');
const CLOUD_BUCKET = process.env.GCLOUD_STORAGE_BUCKET || 'bucket_name';
const PROJECT_ID = process.env.GCLOUD_STORAGE_BUCKET || 'project_id';
const KEY_FILE = process.env.GCLOUD_KEY_FILE || 'service_account_key_file.json';
const PORT = process.env.PORT || 8080;
const storage = new Storage({
projectId: PROJECT_ID,
keyFilename: KEY_FILE
});
const bucket = storage.bucket(CLOUD_BUCKET);
const multer = Multer({
storage: Multer.MemoryStorage,
limits: {
fileSize: 2 * 1024 * 1024 // no larger than 5mb
}
});
const app = express();
app.use('/blog', express.static('blog/dist'));
app.get('/', async (req, res) => {
console.log(process.env);
const [files] = await bucket.getFiles();
res.writeHead(200, { 'Content-Type': 'text/html' });
files.forEach(file => {
res.write(`<div>* ${file.name}</div>`);
console.log(file.name);
});
return res.end();
});
app.get("/gupload", (req, res) => {
res.sendFile(path.join(`${__dirname}/index.html`));
});
// Process the file upload and upload to Google Cloud Storage.
app.post("/pupload", multer.single("file"), (req, res, next) => {
if (!req.file) {
res.status(400).send("No file uploaded.");
return;
}
// Create a new blob in the bucket and upload the file data.
const blob = bucket.file(req.file.originalname);
// Make sure to set the contentType metadata for the browser to be able
// to render the image instead of downloading the file (default behavior)
const blobStream = blob.createWriteStream({
metadata: {
contentType: req.file.mimetype
}
});
blobStream.on("error", err => {
next(err);
return;
});
blobStream.on("finish", () => {
// The public URL can be used to directly access the file via HTTP.
const publicUrl = `https://storage.googleapis.com/${bucket.name}/${blob.name}`;
// Make the image public to the web (since we'll be displaying it in browser)
blob.makePublic().then(() => {
res.status(200).send(`Success!\n Image uploaded to ${publicUrl}`);
});
});
blobStream.end(req.file.buffer);
});
// Start the server
app.listen(PORT, () => {
console.log(`App listening on port ${PORT}`);
console.log('Press Ctrl+C to quit.');
});
