def calculate(a: int=None, b: int=None):c = a + bres = {"res":c}return resif __name__ == '__main__':import uvicornuvicorn.run(app=app,host="0.0.0.0",port=8080,workers=1)

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

构建http post服务

# -*- coding: utf-8 -*-
# @time    : 2019/11/12 21:27
# @author  : Mo
# @function: post service of fastapifrom pydantic import BaseModel
from fastapi import FastAPIapp = FastAPI()class Item(BaseModel):a: int = Noneb: int = None@app.post('/test')
def calculate(request_data: Item):a = request_data.ab = request_data.bc = a + bres = {"res":c}return resif __name__ == '__main__':import uvicornuvicorn.run(app=app,host="0.0.0.0",port=8080,workers=1)

只能使用postman请求
设置body为
{
“a”:1.
“b”:2
}
即可
