同步 API
from refstore import RefStore
# 配置 RefStore
config = {
"minio": {
"endpoint": "localhost:9000",
"access_key": "your_access_key",
"secret_key": "your_secret_key",
"secure": False,
},
"bucket_map": {
"user": "physical-user-bucket",
"public": "physical-public-bucket",
},
"default_bucket": "user",
"presigned_expiry": 3600,
"public_url": "https://cdn.example.com", # 可选,用于生成预签名URL的公共基础URL
}
# 初始化服务
store = RefStore(config)
store.init_buckets()
# 上传文件
uri = store.upload_file(
file_data=b"Hello, RefStore!",
original_filename="test.txt",
content_type="text/plain",
logic_bucket="user",
path="documents"
)
print(f"文件已上传: {uri}") # s3://user/documents/test.txt
# 生成预签名 URL
url = store.get_presigned_url(uri, expiry_seconds=3600)
print(f"下载 URL: {url}")
# 下载文件
data = store.download_file(uri)
print(f"文件内容: {data.decode('utf-8')}")
# 获取文件信息
info = store.get_file_info(uri)
print(f"文件大小: {info['size_human']}")
# 列出文件
files = store.list_files(logic_bucket="user")
print(f"找到 {len(files)} 个文件")
异步 API
import asyncio
from refstore import AsyncRefStore
config = {
"minio": {
"endpoint": "localhost:9000",
"access_key": "your_access_key",
"secret_key": "your_secret_key",
"secure": False,
},
}
async def main():
async with AsyncRefStore(config) as store:
# 上传文件
uri = await store.upload_file(
file_data=b"Hello, Async RefStore!",
original_filename="async_test.txt",
logic_bucket="user"
)
# 下载文件
data = await store.download_file(uri)
print(data.decode('utf-8'))
# 并发上传多个文件
tasks = [
store.upload_file(b"File 1", "file1.txt", "user")
for _ in range(10)
]
uris = await asyncio.gather(*tasks)
asyncio.run(main())
Web API
启动 Web 服务:
from refstore import web_app, init_web_service
config = {
"minio": {
"endpoint": "localhost:9000",
"access_key": "your_access_key",
"secret_key": "your_secret_key",
"secure": False,
},
}
# 初始化 Web 服务
init_web_service(config)
# 启动服务器
if __name__ == "__main__":
import uvicorn
uvicorn.run(web_app, host="0.0.0.0", port=8000)
或使用命令行:
uvicorn refstore.web:web_app --host 0.0.0.0 --port 8000 --reload
访问 API 文档:http://localhost:8000/docs
Web API 客户端
import requests
# 上传文件
with open("test.txt", "rb") as f:
files = {"file": f}
data = {"logic_bucket": "user"}
response = requests.post("http://localhost:8000/upload", files=files, data=data)
result = response.json()
uri = result["uri"]
# 下载文件
params = {"uri": uri}
response = requests.get("http://localhost:8000/download", params=params)
with open("downloaded.txt", "wb") as f:
f.write(response.content)
# 获取文件信息
params = {"uri": uri}
response = requests.get("http://localhost:8000/info", params=params)
info = response.json()
# 生成预签名 URL
params = {"uri": uri, "expiry_seconds": 3600}
response = requests.get("http://localhost:8000/presigned-url", params=params)
presigned_url = response.json()["url"]
配置
完整配置示例
config = {
# MinIO 连接配置(必需)
"minio": {
"endpoint": "localhost:9000", # MinIO 服务器地址
"access_key": "your_access_key", # 访问密钥
"secret_key": "your_secret_key", # 秘密密钥
"secure": False, # 是否使用 HTTPS
},
# 逻辑桶名到物理桶名的映射(可选)
"bucket_map": {
"user": "physical-user-bucket",
"public": "physical-public-bucket",
"temp": "physical-temp-bucket",
},
# 默认逻辑桶名(可选,默认为 "user")
"default_bucket": "user",
# 预签名 URL 过期时间(可选,默认为 3600 秒)
"presigned_expiry": 3600,
# 公共基础 URL(可选,用于生成预签名URL时替换host部分)
# 适用于通过nginx等反向代理访问MinIO的场景
# 例如:如果MinIO在 http://10.31.31.41:9000,但通过 https://cdn.example.com 访问
"public_url": "https://cdn.example.com",
}
配置验证
from refstore import ConfigValidator
# 验证配置
try:
config = ConfigValidator.normalize_config(your_config)
print("配置有效")
except ConfigError as e:
print(f"配置无效: {e}")
# 测试连接
try:
ConfigValidator.test_connection(config)
print("连接成功")
except ConnectionError as e:
print(f"连接失败: {e}")
使用公共URL(反向代理场景)
当你通过nginx等反向代理访问MinIO时,可以使用 public_url 配置来生成使用公共域名的预签名URL:
config = {
"minio": {
"endpoint": "10.31.31.41:9000", # MinIO实际地址
"access_key": "your_access_key",
"secret_key": "your_secret_key",
"secure": False,
},
"public_url": "https://cdn.example.com", # 通过nginx反向代理的公共域名
}
store = RefStore(config)
# 生成的预签名URL将使用 https://cdn.example.com 而不是 http://10.31.31.41:9000
uri = store.upload_file(b"Hello", "test.txt")
url = store.get_presigned_url(uri)
# url: https://cdn.example.com/user-upload/.../test.txt?X-Amz-Algorithm=...
注意:public_url 只影响预签名URL的生成,MinIO客户端的连接仍然使用 endpoint 配置。
URI 操作
RefStore 使用标准化的 S3 URI 格式:s3://logic_bucket/path/to/file
from refstore import encode_uri, decode_uri, validate_uri, get_bucket_from_uri
# 编码 URI
uri = encode_uri("user", "documents/report.pdf")
# s3://user/documents/report.pdf
# 解码 URI
bucket, object_name = decode_uri(uri)
# bucket: user, object_name: documents/report.pdf
# 验证 URI
is_valid = validate_uri(uri)
# True
# 提取桶名
bucket = get_bucket_from_uri(uri)
# user
# 提取对象名称
object_name = get_object_name_from_uri(uri)
# documents/report.pdf
# 获取文件扩展名
ext = get_file_extension(uri)
# .pdf
高级功能
重试机制
from refstore import retry_with_backoff
@retry_with_backoff(max_retries=3, base_delay=1.0)
def upload_with_retry(store, data, filename):
return store.upload_file(data, filename)
桶管理
from refstore import BucketManager
# 创建桶管理器
bucket_manager = BucketManager(minio_client)
# 创建桶
bucket_manager.create_bucket("my-bucket")
# 检查桶是否存在
exists = bucket_manager.bucket_exists("my-bucket")
# 列出所有桶
buckets = bucket_manager.list_buckets()
# 获取桶信息
info = bucket_manager.get_bucket_info("my-bucket")
# 删除桶
bucket_manager.delete_bucket("my-bucket", force=True)
批量操作
# 批量删除文件
uris = [
"s3://user/file1.txt",
"s3://user/file2.txt",
"s3://user/file3.txt",
]
result = store.delete_files(uris)
print(f"删除成功: {len(result['deleted'])}")
print(f"删除失败: {len(result['failed'])}")
