FastAPI+aiohttp+uvicorn快速搭建个人服务

背景

当你想搭建一套服务实现某个demo或者是小型服务，最快的方式就是使用fastapi+aiohttp+uvicorn。

案例

1、服务端接口

# -*- encoding: utf-8 -*-
import aiohttp
import uvicorn
from fastapi import FastAPI

app = FastAPI()


@app.get("/api")
async def api():
    async with aiohttp.ClientSession() as session:
        async with session.post("http://jsonplaceholder.typicode.com/posts") as response:
            return await response.json()


if __name__ == '__main__':
    uvicorn.run(app, host="0.0.0.0", port=8080)

请求的地址：
curl http://localhost:8080/api

返回结果：
INFO:     127.0.0.1:58407 - "GET /api HTTP/1.1" 200 OK
INFO:     127.0.0.1:58407 - "GET /api HTTP/1.1" 200 OK
INFO:     127.0.0.1:58407 - "GET /api HTTP/1.1" 200 OK
INFO:     127.0.0.1:58407 - "GET /api HTTP/1.1" 200 OK

2、请求端接口

# -*- encoding: utf-8 -*-
import aiohttp
from fastapi import FastAPI
import asyncio


async def req():
    async with aiohttp.ClientSession() as session:
        async with session.get("http://localhost:8080/api") as response:
            return await response.json()


if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    result = loop.run_until_complete(req())
    print(result)
