fastapi路由管理

fastapi路由管理，和GIN的框架思想一致。
入口函数----主路由---控制器---服务

1. main入口函数，需要include api_router

from router.api import api_router
app = FastAPI()
app.include_router(api_router, prefix="/api")

if __name__ == "__main__":
    uvicorn.run(app, host="127.0.0.1", port=8081)

2. 路由文件，必须导入实际的控制文件，每个控制文件设置一个router

from fastapi import APIRouter
from control import user

api_router = APIRouter()

api_router.include_router(user.router, prefix="/user")

3. 实际的控制文件，设置好子路由

from typing import List
from fastapi import Depends, FastAPI, HTTPException, APIRouter
from pydantic import BaseModel

from services import user_services
from models import user_models

router = APIRouter()

class UserSchemas(BaseModel):
    username: str
    fullname: str
    password: str

@router.get("/{username}")
def get_user(username: str):
    print(username)
    user = user_services.get_user_by_username(username)    
    return user
