El comando `uvicorn main:app` se refiere a:

* `main`: el archivo `main.py` (el "módulo" de Python).
* `app`: el objeto creado dentro de `main.py` con la línea `app = FastAPI()`.

Es equivalente a:

```Python
from main import app
```

///

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

Or more exactly, using `user_dict` directly, with whatever contents it might have in the future:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

├── backend
│   ├── main.py
│   ├── __init__.py
```

那麼你應該把 `entrypoint` 設為：

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

這等同於：

```python
from backend.main import app
```

### 帶路徑的 `fastapi dev` { #fastapi-dev-with-path }

你也可以把檔案路徑傳給 `fastapi dev` 指令，它會推測要使用的 FastAPI app 物件：

```console
$ fastapi dev main.py
```

但這樣每次呼叫 `fastapi` 指令時都得記得傳入正確的路徑。

val copyResourcesTemplates =
  tasks.register<Copy>("copyResourcesTemplates") {
    from("src/main/resources-templates")
    into(layout.buildDirectory.dir("generated/resources-templates"))
    expand("projectVersion" to "${project.version}")
    filteringCharset = Charsets.UTF_8.toString()
  }

configure<JavaPluginExtension> {
  sourceSets.getByName("main").resources.srcDir(copyResourcesTemplates.get().outputs)
}

dependencies {

Depois que você tiver testes, você pode atualizar a sua versão do **FastAPI** para uma mais recente e se certificar de que todo o seu código está funcionando corretamente executando seus testes.

Se tudo estiver funcionando, ou após você realizar as alterações necessárias e todos os testes estiverem passando, então você pode fixar sua versão de `fastapi` para essa versão mais recente.

ファイル `main.py` に **FastAPI** アプリがあります:


{* ../../docs_src/app_testing/app_a_py310/main.py *}

### テストファイル { #testing-file }

次に、テストを含む `test_main.py` ファイルを用意できます。これは同じ Python パッケージ (`__init__.py` ファイルがある同じディレクトリ) に置けます:

``` hl_lines="5"

│   └── test_main.py
```

		Method: http.MethodPost,
		URL:    u,
	}
	if !guessIsRPCReq(r) {
		t.Fatal("Test shouldn't fail for a possible net/rpc request.")
	}
	r = &http.Request{
		Proto:  "HTTP/1.1",
		Method: http.MethodGet,
		URL:    u,
	}
	if !guessIsRPCReq(r) {
		t.Fatal("Test shouldn't fail for a possible net/rpc request.")
	}
	r = &http.Request{
		Proto:  "HTTP/1.1",
		Method: http.MethodGet,

        message = f"found query: {q}\n"
        background_tasks.add_task(write_log, message)
    return q


@app.post("/send-notification/{email}")
async def send_notification(
    email: str, background_tasks: BackgroundTasks, q: Annotated[str, Depends(get_query)]
):
    message = f"message to {email}\n"
    background_tasks.add_task(write_log, message)

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

Или, более точно, если использовать `user_dict` напрямую, с любым содержимым, которое он может иметь в будущем:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

/// note

指令 `uvicorn main:app` 指的是：

* `main`：檔案 `main.py`（Python「模組」）。
* `app`：在 `main.py` 中以 `app = FastAPI()` 建立的物件。

等同於：

```Python
from main import app
```

///

其他 ASGI 伺服器也有類似的指令，詳見各自的文件。

/// warning

Uvicorn 與其他伺服器支援 `--reload` 選項，對開發期間很有幫助。
