使用fastapi写一个http接口

一，使用工具：FastAPI和uvicorn

通常我们写一个简单的http接口时常用flask，这次用点不一样的。
FastAPI是一个快速（高性能）的Web框架，需Python 3.6以上，安装方法：pip install fastapi
uvicorn是一个基于asyncio开发的一个轻量级高效的web服务器框架。需python3.5.3以上，安装方法：pip install uvicorn

二，get接口

# !/usr/bin/python
# -*- coding: utf-8 -*-
# @time    : 2020/07/10 20:27
# @author  : LanBingWa
# @function: get service of fastapi

from fastapi import FastAPI
import uvicorn


app = FastAPI()


@app.get('/test/a={a}/b={b}')
def calculate(a: int = None, b: int = None):
    c = a + b
    res = {"res": c}
    return res


if __name__ == '__main__':
    uvicorn.run(app=app,
                host="0.0.0.0",
                port=8080,
                workers=1)

浏览器访问接口:http://127.0.0.1:8080/test/a=3/b=8

三，post接口

# !/usr/bin/python
# -*- coding: utf-8 -*-
# @time    : 2020/07/10 20:43
# @author  : LanBingWa
# @function: post service of fastapi

from pydantic import BaseModel
from fastapi import FastAPI
import uvicorn


app = FastAPI()


class Item(BaseModel):
    a: int = None
    b: int = None


@app.post('/test')
def calculate(request_data: Item):
    a = request_data.a
    b = request_data.b
    c = a + b
    res = {"res": c}
    return res


if __name__ == '__main__':
    uvicorn.run(app=app,
                host="0.0.0.0",
                port=8080,
                workers=1)
