Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then **install FastAPI**:

<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.

FastAPI 可以进行识别，并生成表明无响应体的 OpenAPI 文档。

## 关于 HTTP 状态码

/// note | "笔记"

如果已经了解 HTTP 状态码，请跳到下一章。

///

在 HTTP 协议中，发送 3 位数的数字状态码是响应的一部分。

这些状态码都具有便于识别的关联名称，但是重要的还是数字。

简言之：

* `100` 及以上的状态码用于返回**信息**。这类状态码很少直接使用。具有这些状态码的响应不能包含响应体
* **`200`** 及以上的状态码用于表示**成功**。这些状态码是最常用的
    * `200` 是默认状态代码，表示一切**正常**
    * `201` 表示**已创建**，通常在数据库中创建新记录后使用
    * `204` 是一种特殊的例子，表示**无内容**。该响应在没有为客户端返回内容时使用，因此，该响应不能包含响应体
