在当前目录创建文件夹 test，并创建三个文件 fapi.py、test/t1.py、test/__init__.py。目录结构如下

.
├── fapi.py
└── test
    ├── __init__.py
    └── t1.py

主文件 fapi.py

# -*- coding: utf-8 -*-
from fastapi import FastAPI 
from fastapi import APIRouter
import uvicorn

from test import t1

api_router = APIRouter()
api_router.include_router(t1.test_router, prefix="/test", tags=["CCCCCCCCCCCCCCCCC"] )

def create_app():
    tags_metadata = [{ "name": "测试APIII", "description": "fastapi 练习" }]
    # 创建api应用
    app = FastAPI( title="测试API", description="learnlearn", version="1.0", docs_url="/docs", openapi_url="/api/api.json", openapi_tags=tags_metadata)
    # 增加路由
    app.include_router( api_router, prefix="/tt")

    return app

# 创建一个应用
testapp = create_app()

if __name__ == "__main__":
    uvicorn.run(app='fapi:testapp', host="0.0.0.0", port=3456, reload=True)

在test目录下创建 t1.py 文件

# -*- coding: utf-8 -*-

from fastapi import status
from fastapi import APIRouter
from fastapi.responses import JSONResponse, Response
from pydantic import BaseModel
from fastapi import Body

# 创建路由
test_router = APIRouter()

# get请求处理
@test_router.get("/t1", summary=u"第一个测试")
def t1( a: str = "<not given>", b: str = "<not given>") -> Response :
    pstr = "param a is ["+a+"]; param b is ["+b+"]"
    return JSONResponse(
        status_code=status.HTTP_200_OK,
        content = {
            "code": "1001",
            "message": "hello , first fast api return",
            "params" : pstr
        })

class Item(BaseModel):
    aa: str = "<not given>"
    bb: str = "<not given>"

# post请求
@test_router.post("/t1", summary=u"第一个测试")
def t1_post(item: Item = Body(...)) -> Response :
    datastr = "param a is ["+item.aa+"]; param b is ["+item.bb+"]"
    return JSONResponse(
        status_code=status.HTTP_200_OK,
        content = {
            "code": "1002",
            "message": "hello , first fast api return",
            "datastr": datastr
        })

在test目录下创建空文件 __init__.py
