## Installation { #installation }

Create and activate a [virtual environment](https://fastapi.tiangolo.com/virtual-environments/) and then install FastAPI:

<div class="termy">

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

---> 100%
```

</div>

{* ../../docs_src/response_model/tutorial002_py310.py hl[7,9] *}

/// info

To use `EmailStr`, first install [`email-validator`](https://github.com/JoshData/python-email-validator).

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and then install it, for example:

```console
$ pip install email-validator
```

or with:

```console
$ pip install "pydantic[email]"
```

///

Example:

```sh

        });
        return asJson(new ApiResponse().status(Status.OK).result());
    }

    /**
     * Creates an EditBody from a DataConfig entity for API responses.
     * Handles permission and virtual host encoding.
     *
     * @param entity the DataConfig entity to convert
     * @return the converted EditBody object
     */
    protected EditBody createEditBody(final DataConfig entity) {

```

</div>

**强烈建议**您在本地编写或复制代码，对其进行编辑并运行。

在编辑器中使用 FastAPI 会真正地展现出它的优势：只需要编写很少的代码，所有的类型检查，代码补全等等。

## 安装 FastAPI { #install-fastapi }

第一个步骤是安装 FastAPI.

请确保您创建并激活一个[虚拟环境](../virtual-environments.md)，然后**安装 FastAPI**：

<div class="termy">

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

---> 100%
```

</div>

/// note | 注意

에디터에서 사용해 보면, 작성해야 하는 코드가 얼마나 적은지, 모든 타입 검사와 자동완성 등 FastAPI의 이점을 제대로 확인할 수 있습니다.

## FastAPI 설치 { #install-fastapi }

첫 단계는 FastAPI를 설치하는 것입니다.

[가상 환경](../virtual-environments.md)을 생성하고 활성화한 다음, **FastAPI를 설치**하세요:

<div class="termy">

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

---> 100%
```

</div>

/// note | 참고

        });
        return asJson(new ApiResponse().status(Status.OK).result());
    }

    /**
     * Creates an edit body from a file configuration entity for API responses.
     * Processes permissions and virtual hosts for proper display formatting.
     *
     * @param entity the file configuration entity to convert
     * @return edit body containing the entity data
     */

## Install `SQLModel` { #install-sqlmodel }

First, make sure you create your [virtual environment](../virtual-environments.md), activate it, and then install `sqlmodel`:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

# WebSockets { #websockets }

您可以在 **FastAPI** 中使用 [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)。

## 安装 `websockets` { #install-websockets }

请确保您创建一个[虚拟环境](../virtual-environments.md)、激活它，并安装 `websockets`（一个让使用“WebSocket”协议更容易的 Python 库）：

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## WebSockets 客户端 { #websockets-client }

# Fess log directory
LOG_DIR=${packaging.fess.log.dir}

# Fess data directory
DATA_DIR=${packaging.fess.var.dir}

# Fess configuration directory
CONF_DIR=${packaging.fess.conf.dir}

# Maximum number of VMA (Virtual Memory Areas) a process can own
MAX_MAP_COUNT=262144

# Path to the GC log file
#FESS_GC_LOG_FILE=/var/log/fess/gc.log

# Fess PID file directory
PID_DIR=${packaging.fess.pid.dir}
