Python中如何实现基于队列的分布式文件系统

pip install celery redis

from celery import Celery

app = Celery('distributed_filesystem')

# 配置Redis作为任务队列中间件
app.conf.update(
    broker_url='redis://localhost:6379/0',
    result_backend='redis://localhost:6379/1'
)

import os

@app.task
def upload_file(file_path: str, file_content: str):
    # 将内容写入指定文件
    with open(file_path, 'w') as f:
        f.write(file_content)

@app.task
def download_file(file_path: str) -> str:
    # 读取指定文件的内容
    with open(file_path, 'r') as f:
        return f.read()

class DistributedFS:

    def __init__(self, root_dir: str):
        self.root_dir = root_dir

    def upload_file(self, file_name: str, file_content: str):
        file_path = os.path.join(self.root_dir, file_name)
        upload_file.delay(file_path, file_content)

    def download_file(self, file_name: str) -> str:
        file_path = os.path.join(self.root_dir, file_name)
        return download_file.delay(file_path).get()

dfs = DistributedFS('/mnt/data')
dfs.upload_file('test.txt', 'pidancode.com')
content = dfs.download_file('test.txt')
print(content)  # 输出：pidancode.com
