from fastapi import FastAPI

app = FastAPI()


@app.get("/items/", tags=["items"])
async def read_items():
    return [{"name": "Foo", "price": 42}]


@app.get("/users/", tags=["users"])
async def read_users():
    return [{"username": "johndoe"}]


@app.get("/elements/", tags=["items"], deprecated=True)
async def read_elements():

from fastapi import FastAPI

app = FastAPI()


@app.on_event("shutdown")
def shutdown_event():
    with open("log.txt", mode="a") as log:
        log.write("Application shutdown")


@app.get("/items/")
async def read_items():

然后我们对 `users` 模块进行相同的操作。

我们也可以像这样导入它们：

```Python
from app.routers import items, users
```

/// info

第一个版本是「相对导入」：

```Python
from .routers import items, users
```

第二个版本是「绝对导入」：

```Python
from app.routers import items, users
```
