5.3 FastAPI框架
安装
pip3 install fastapi pip3 install uvicorn (asgi内部基于uvloop)
示例： luffy.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import asyncio
import uvicorn
import aioredis
from aioredis import Redis
from fastapi import FastAPI
app = FastAPI()
# 创建一个redis连接池
REDIS_POOL = aioredis.ConnectionsPool('redis://47.193.14.198:6379', password="root123", minsize=1, maxsize=10)
@app.get("/")
def index():
""" 普通操作接口 """
return {"message": "Hello World"}
@app.get("/red")
async def red():
""" 异步操作接口 """
print("请求来了")
await asyncio.sleep(3)
# 连接池获取一个连接
conn = await REDIS_POOL.acquire()
redis = Redis(conn)
# 设置值
await redis.hmset_dict('car', key1=1, key2=2, key3=3)
# 读取值
result = await redis.hgetall('car', encoding='utf-8')
print(result)
# 连接归还连接池
REDIS_POOL.release(conn)
return result
if __name__ == '__main__':
uvicorn.run("luffy:app", host="127.0.0.1", port=5000, log_level="info")
