# Test Client - `TestClient`

You can use the `TestClient` class to test FastAPI applications without creating an actual HTTP and socket connection, just communicating directly with the FastAPI code.

Read more about it in the [FastAPI docs for Testing](https://fastapi.tiangolo.com/tutorial/testing/).

You can import it directly from `fastapi.testclient`:

```python
from fastapi.testclient import TestClient
```

즉, Python에서 환경 변수로부터 읽어온 어떤 값이든 `str`이 되며, 다른 타입으로의 변환이나 검증은 코드에서 수행해야 합니다.

## Pydantic `Settings` { #pydantic-settings }

다행히 Pydantic은 환경 변수에서 오는 이러한 설정을 처리할 수 있는 훌륭한 유틸리티를 [Pydantic: Settings 관리](https://docs.pydantic.dev/latest/concepts/pydantic_settings/)로 제공합니다.

### `pydantic-settings` 설치하기 { #install-pydantic-settings }

먼저 [가상 환경](../virtual-environments.md)을 만들고 활성화한 다음, `pydantic-settings` 패키지를 설치하세요:

這表示在 Python 中自環境變數讀取到的任何值都會是 `str`，而任何轉型成其他型別或驗證都必須在程式碼中完成。

## Pydantic `Settings` { #pydantic-settings }

幸好，Pydantic 提供了很好的工具，可用來處理由環境變數而來的設定：[Pydantic：設定管理](https://docs.pydantic.dev/latest/concepts/pydantic_settings/)。

### 安裝 `pydantic-settings` { #install-pydantic-settings }

首先，請先建立你的[虛擬環境](../virtual-environments.md)，啟用它，然後安裝 `pydantic-settings` 套件：

<div class="termy">

請注意，`status_code` 是「裝飾器（decorator）」方法（`get`、`post` 等等）的參數，而不是你的「路徑操作函式」的參數，就像所有的參數與 body 一樣。

///

參數 `status_code` 接受一個數字作為 HTTP 狀態碼。

/// info | 資訊

`status_code` 也可以接收一個 `IntEnum`，例如 Python 的 [`http.HTTPStatus`](https://docs.python.org/3/library/http.html#http.HTTPStatus)。

///

它會：

* 在回應中傳回該狀態碼。
* 在 OpenAPI 結構中如此記錄（因此也會反映在使用者介面中）：

/// note | 注意

# Middleware

There are several middlewares available provided by Starlette directly.

Read more about them in the [FastAPI docs for Middleware](https://fastapi.tiangolo.com/advanced/middleware/).

::: fastapi.middleware.cors.CORSMiddleware

It can be imported from `fastapi`:

```python
from fastapi.middleware.cors import CORSMiddleware
```

::: fastapi.middleware.gzip.GZipMiddleware

It can be imported from `fastapi`:
