Dans ce cas, vous pouvez simplement remplacer les `dataclasses` standard par `pydantic.dataclasses`, qui est un remplacement drop‑in :

{* ../../docs_src/dataclasses_/tutorial003_py310.py hl[1,4,7:10,13:16,22:24,27] *}

1. Nous continuons à importer `field` depuis les `dataclasses` standard.

2. `pydantic.dataclasses` est un remplacement drop‑in pour `dataclasses`.

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note

When you install with `pip install "fastapi[standard]"` it comes with some default optional standard dependencies, including `fastapi-cloud-cli`, which allows you to deploy to [FastAPI Cloud](https://fastapicloud.com).

In diesem Fall können Sie einfach die Standard-`dataclasses` durch `pydantic.dataclasses` ersetzen, was einen direkten Ersatz darstellt:

{* ../../docs_src/dataclasses_/tutorial003_py310.py hl[1,4,7:10,13:16,22:24,27] *}

1. Wir importieren `field` weiterhin von Standard-`dataclasses`.

2. `pydantic.dataclasses` ist ein direkter Ersatz für `dataclasses`.

In that case, you can simply swap the standard `dataclasses` with `pydantic.dataclasses`, which is a drop-in replacement:

{* ../../docs_src/dataclasses_/tutorial003_py310.py hl[1,4,7:10,13:16,22:24,27] *}

1. We still import `field` from standard `dataclasses`.

2. `pydantic.dataclasses` is a drop-in replacement for `dataclasses`.

### OpenAPI { #openapi }

**FastAPI** generates a "schema" with all your API using the **OpenAPI** standard for defining APIs.

#### "Schema" { #schema }

A "schema" is a definition or description of something. Not the code that implements it, but just an abstract description.

#### API "schema" { #api-schema }

`pip install "fastapi[standard]"` ile kurduğunuzda, bazı varsayılan opsiyonel standard bağımlılıklarla birlikte gelir. Bunlara `fastapi-cloud-cli` da dahildir; bu sayede [FastAPI Cloud](https://fastapicloud.com)'a deploy edebilirsiniz.

* [`uvicorn`](https://www.uvicorn.dev) - 加载并提供你的应用的服务器。包含 `uvicorn[standard]`，其中包含高性能服务所需的一些依赖（例如 `uvloop`）。
* `fastapi-cli[standard]` - 提供 `fastapi` 命令。
    * 其中包含 `fastapi-cloud-cli`，它允许你将 FastAPI 应用部署到 [FastAPI Cloud](https://fastapicloud.com)。

### 不包含 `standard` 依赖 { #without-standard-dependencies }

如果你不想包含这些 `standard` 可选依赖，可以使用 `pip install fastapi`，而不是 `pip install "fastapi[standard]"`。
