**Spoiler alert**: the tutorial - user guide includes:

* Declaration of **parameters** from other different places as: **headers**, **cookies**, **form fields** and **files**.
* How to set **validation constraints** as `maximum_length` or `regex`.
* A very powerful and easy to use **<dfn title="also known as components, resources, providers, services, injectables">Dependency Injection</dfn>** system.

**劇透警告**：教學 - 使用者指南包含：

* 來自不同來源的**參數**宣告：例如 **headers**、**cookies**、**form fields** 和 **files**。
* 如何設定**驗證限制**，如 `maximum_length` 或 `regex`。
* 一個非常強大且易用的 **<dfn title="也稱為：components、resources、providers、services、injectables">依賴注入</dfn>** 系統。
* 安全與驗證，包含支援 **OAuth2** 搭配 **JWT tokens** 與 **HTTP Basic** 驗證。
* 宣告**深度巢狀 JSON 模型**的進階（但同樣簡單）技巧（感謝 Pydantic）。

你还可以添加 `min_length` 参数：

{* ../../docs_src/query_params_str_validations/tutorial003_an_py310.py hl[10] *}

## 添加正则表达式 { #add-regular-expressions }

你可以定义一个参数必须匹配的 <dfn title="正则表达式（regex 或 regexp）是用于定义字符串搜索模式的字符序列。">正则表达式</dfn> `pattern`：

{* ../../docs_src/query_params_str_validations/tutorial004_an_py310.py hl[11] *}

这个特定的正则表达式通过以下规则检查接收到的参数值：

- `^`：必须以接下来的字符开头，前面没有其他字符。

`min_length` 매개변수도 추가할 수 있습니다:

{* ../../docs_src/query_params_str_validations/tutorial003_an_py310.py hl[10] *}

## 정규식 추가 { #add-regular-expressions }

매개변수와 일치해야 하는 <dfn title="정규 표현식(regex 또는 regexp)은 문자열에 대한 검색 패턴을 정의하는 문자 시퀀스입니다.">정규 표현식</dfn> `pattern`을 정의할 수 있습니다:

{* ../../docs_src/query_params_str_validations/tutorial004_an_py310.py hl[11] *}

이 특정 정규표현식 패턴은 전달 받은 매개변수 값이 다음을 만족하는지 검사합니다:
