快速使用
from pathlib import Path
import os
from nutricare_data_packages import StorageBase
class ReportStorage(StorageBase):
@property
def storage_subdir(self) -> str:
return "reports"
def _write_impl(self, relative_path: str, data: bytes) -> Path:
target = self.resolve_path(relative_path)
target.parent.mkdir(parents=True, exist_ok=True)
target.write_bytes(data)
return target
os.environ["mongodb_url"] = "127.0.0.1:27017"
os.environ["NUTRICARE_TICKET_ID"] = "ticket-001"
os.environ["NUTRICARE_TASK_ID"] = "task-001"
storage = ReportStorage()
storage.write_metadata(
relative_path=relative_path,
size=len(content),
md5="...",
status="pending",
)
path = storage.write(relative_path, content)
说明:
- MongoDB 连接串只从环境变量
mongodb_url读取。 - 允许传入
127.0.0.1:27017、mongodb:127.0.0.1:27017或完整mongodb://...。 - 文件写入会按
relative_path + md5做幂等校验,已存在且一致时直接返回。
