### FastAPI Uygulamasında `root_path` Ayarlama { #setting-the-root-path-in-the-fastapi-app }

fastapi[standard]==0.113.0
pydantic==2.8.0
```

///

## 运行程序 { #run-your-program }

在你激活虚拟环境后，你可以运行你的程序，它将使用虚拟环境中的 Python 和你在其中安装的软件包。

<div class="termy">

```console
$ python main.py

Hello World
```

</div>

## 配置编辑器 { #configure-your-editor }

你可能会用到编辑器，请确保配置它使用与你创建的相同的虚拟环境（它可能会自动检测到），以便你可以获得自动补全和内联错误提示。

例如：

* `app` 디렉터리를 만들고 들어갑니다.
* 빈 파일 `__init__.py`를 만듭니다.
* 다음 내용으로 `main.py` 파일을 만듭니다:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: str | None = None):
    return {"item_id": item_id, "q": q}
```

### Dockerfile { #dockerfile }

@app.post("/data")
def post_data(body: DataInput):
    content = body.data.decode("utf-8")
    return {"description": body.description, "content": content}


@app.get("/data")
def get_data() -> DataOutput:
    data = "hello".encode("utf-8")
    return DataOutput(description="A plumbus", data=data)


@app.post("/data-in-out")
def post_data_in_out(body: DataInputOutput) -> DataInputOutput:

from docs_src.behind_a_proxy.tutorial002_py310 import app

client = TestClient(app)


def test_main():
    response = client.get("/app")
    assert response.status_code == 200
    assert response.json() == {"message": "Hello World", "root_path": "/api/v1"}


def test_openapi():
    response = client.get("/openapi.json")
    assert response.status_code == 200
    assert response.json() == snapshot(
        {

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

La réponse sera semblable à :

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```
