fastapi学习之路

一、python3写一个http接口服务，给别人调用3

    这次选择fastapi，FastAPI是一个现代的、快速（高性能）的web框架，用于基于标准Python类型提示使用Python 3.6+构建api。具有快速、快速编码、更少的错误、直观、简单、简便、健壮。简易而且本地win10能够跑起来。

二、FastAPI的get接口代码实现

    1.  安装:  pip install fastapi

               pip install uvicorn

    2.  代码:  

# !/usr/bin/python
# -*- coding: utf-8 -*-
# @time    : 2019/11/12 21:27
# @author  : Mo
# @function: get service of fastapi
 
from fastapi import FastAPI
 
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__':
    import uvicorn
    uvicorn.run(app=app,
                host="0.0.0.0",
                port=8080,
                workers=1)

3. 接口访问:http://127.0.0.1:8080/test/a=1/b=4

浏览器访问结果:

postman访问结果:

三、FastAPI的post接口代码实现

    1.  安装:  pip install fastapi

                   pip install uvicorn

    2.  代码:  

# !/usr/bin/python
# -*- coding: utf-8 -*-
# @time    : 2019/11/12 21:27
# @author  : Mo
# @function: post service of fastapi
 
from pydantic import BaseModel
from fastapi import FastAPI
 
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__':
    import uvicorn
    uvicorn.run(app=app,
                host="0.0.0.0",
                port=8080,
                workers=1)

    3.  接口访问:http://127.0.0.1:8080/test

         postman访问结果:
