使用签名URL将“PUTv-file-inputfiletogooglebucket上传到GoogleBucket。 -火山引擎

import google.auth
from google.cloud import storage
from google.oauth2.credentials import Credentials
# 身份验证
credentials, project_id = google.auth.default()
# 建立 Storage 客户端并获取 bucket
client = storage.Client(credentials=credentials, project=project_id)
bucket = client.get_bucket('your-bucket-name')
# 定义上传文件的名称
filename = 'example.txt'
# 定义请求的 HTTP 方法，本例中为 PUT
http_method = 'PUT'
# 定义文件在 bucket 中的存储路径
object_name = f'files/{filename}'
# 生成签名 URL
url = bucket.blob(object_name).generate_signed_url(
    version='v4',
    expiration=datetime.timedelta(minutes=15),
    method=http_method,
    credentials=Credentials.from_service_account_file('/path/to/credentials.json')
print(f'签名 URL 为：{url}')
生成签名 URL 后，即可使用 axios 等工具将文件上传到 Bucket，代码如下：
import axios from 'axios';
const url = 'https://storage.googleapis.com/your-bucket-name/files/example.txt?X-Goog-Algorithm=GOOG4-RSA-SHA256&X-Goog-Credential=<credential>&X-Goog-Date=<date>&X-Goog-Expires=900&X-Goog-SignedHeaders=host';
const fileInput = document.querySelector('input[type="file"]');
const file = fileInput.files[0];
axios.put(url, file)
  .then(response => {
    console.log('文件上传成功！');
  .catch(error => {
    console.error('文件上传失败：', error);
将 url 替换为生成的签名 URL 即可。
