No Pydantic v1 o método se chamava `.dict()`, ele foi descontinuado (mas ainda é suportado) no Pydantic v2, e renomeado para `.model_dump()`.

Os exemplos aqui usam `.dict()` para compatibilidade com o Pydantic v1, mas você deve usar `.model_dump()` se puder usar o Pydantic v2.

#### Путь (path) { #path }

Здесь «путь» — это последняя часть URL, начиная с первого символа `/`.

Итак, в таком URL:

```
https://example.com/items/foo
```

...путь будет:

```
/items/foo
```

/// info | Информация

«Путь» также часто называют «эндпоинт» или «маршрут».

///

这里的变量 `app` 会是 `FastAPI` 类的一个「实例」。

这个实例将是创建你所有 API 的主要交互对象。

### 步骤 3：创建一个*路径操作*

#### 路径

这里的「路径」指的是 URL 中从第一个 `/` 起的后半部分。

所以，在一个这样的 URL 中：

```
https://example.com/items/foo
```

...路径会是：

```
/items/foo
```

/// info

「路径」也通常被称为「端点」或「路由」。

///

开发 API 时，「路径」是用来分离「关注点」和「资源」的主要手段。

#### 操作

![editor support](https://fastapi.tiangolo.com/img/pycharm-completion.png)

You will get completion in code you might even consider impossible before. As for example, the `price` key inside a JSON body (that could have been nested) that comes from a request.

```sh
go install github.com/minio/minio@latest
```

You can alternatively run `go build` and use the `GOOS` and `GOARCH` environment variables to control the OS and architecture target.
For example:

```
env GOOS=linux GOARCh=arm64 go build
```

Start MinIO by running `minio server PATH` where `PATH` is any empty folder on your local filesystem.

**Nota**: Asegúrate de poner `"fastapi[standard]"` entre comillas para asegurar que funcione en todas las terminales.

## Ejemplo { #example }

### Créalo { #create-it }

Crea un archivo `main.py` con:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")

$ pip install "fastapi[standard]"

---> 100%
```

</div>

**Nota**: Certifique-se de que você colocou `"fastapi[standard]"` com aspas, para garantir que funcione em todos os terminais.

## Exemplo { #example }

### Crie { #create-it }

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()
