Создайте параметры `File` так же, как вы это делаете для `Body` или `Form`:

## `UploadFile` ⏮️ 🌖 🗃

👆 💪 ⚙️ `File()` ⏮️ `UploadFile`, 🖼, ⚒ 🌖 🗃:

```Python hl_lines="13"

```Python hl_lines="6  11"
{!../../../docs_src/path_params/tutorial003.py!}
```

Otherwise, the path for `/users/{user_id}` would match also for `/users/me`, "thinking" that it's receiving a parameter `user_id` with a value of `"me"`.

Similarly, you cannot redefine a path operation:

```Python hl_lines="6  11"
{!../../../docs_src/path_params/tutorial003b.py!}
```

```Python hl_lines="6  11"
{!../../../docs_src/path_params/tutorial003.py!}
```

Иначе путь для `/users/{user_id}` также будет соответствовать `/users/me`, "подразумевая", что он получает параметр `user_id` со значением `"me"`.

Аналогично, вы не можете переопределить операцию с путем:

```Python hl_lines="6  11"
{!../../../docs_src/path_params/tutorial003b.py!}
```

同样也可以在异常处理器中访问请求体。

此时要做的只是处理 `try`/`except` 中的请求：

```Python hl_lines="13  15"
{!../../../docs_src/custom_request_and_route/tutorial002.py!}
```

发生异常时，`Request` 实例仍在作用域内，因此处理错误时可以读取和使用请求体：

```Python hl_lines="16-18"
{!../../../docs_src/custom_request_and_route/tutorial002.py!}
```

## 在路由中自定义 `APIRoute` 类

您还可以设置 `APIRoute` 的 `route_class` 参数：

```Python hl_lines="26"
