## Спробуйте { #try-it }

Розмістіть код у файлі `main.py`, а потім запустіть ваш застосунок:

<div class="termy">

```console
$ fastapi dev

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

### Proporcionando el `root_path` { #providing-the-root-path }

Para lograr esto, puedes usar la opción de línea de comandos `--root-path` como:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

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

</div>

        SourceSetContainer javaSourceSets = GradleUtils.getJavaSourceSets(getProject());
        if (javaSourceSets.findByName(SourceSet.MAIN_SOURCE_SET_NAME) == null) {
            // some test projects don't have a main source set
            return Collections.emptySet();
        }
        return javaSourceSets.getByName(SourceSet.MAIN_SOURCE_SET_NAME)
            .getOutput()
            .getClassesDirs()

如果你不去停用 `philosophers-stone` 的虛擬環境，當你在終端中執行 `python` 時，它會嘗試使用 `philosophers-stone` 中的 Python。

<div class="termy">

```console
$ cd ~/code/prisoner-of-azkaban

$ python main.py

// 匯入 sirius 錯誤，未安裝 😱
Traceback (most recent call last):
    File "main.py", line 1, in <module>
        import sirius
```

</div>

但如果你停用虛擬環境並啟用 `prisoner-of-azkaban` 的新虛擬環境，那麼當你執行 `python` 時，它會使用 `prisoner-of-azkaban` 中虛擬環境的 Python。

如果你不去停用 `philosophers-stone` 的虚拟环境，当你在终端中运行 `python` 时，它会尝试使用 `philosophers-stone` 中的 Python。

<div class="termy">

```console
$ cd ~/code/prisoner-of-azkaban

$ python main.py

// 导入 sirius 报错，它没有安装 😱
Traceback (most recent call last):
    File "main.py", line 1, in <module>
        import sirius
```

</div>

但是如果你停用虚拟环境并激活 `prisoner-of-askaban` 的新虚拟环境，那么当你运行 `python` 时，它会使用 `prisoner-of-askaban` 中的虚拟环境中的 Python。

    /*

     * to confirm that it is running. If the main thread's stop() call happens
     * before it has the chance, the test will fail. To avoid this, the main
     * thread calls this method, which waits until the service has performed

### Providing the `root_path` { #providing-the-root-path }

To achieve this, you can use the command line option `--root-path` like:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

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

</div>

### 提供 `root_path` { #providing-the-root-path }

为此，你可以像下面这样使用命令行选项 `--root-path`：

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

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

</div>

如果你使用 Hypercorn，它也有 `--root-path` 选项。

</div>

**Not**: Tüm terminallerde çalıştığından emin olmak için `"fastapi[standard]"` ifadesini tırnak içinde yazdığınızdan emin olun.

## Örnek { #example }

### Oluşturalım { #create-it }

Şu içerikle `main.py` adında bir dosya oluşturalım:

```Python
from fastapi import FastAPI

app = FastAPI()


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