  /**
   * Not checking the CA bit created a vulnerability in old OkHttp releases. It is exploited by
   * triggering different chains to be discovered by the TLS engine and our chain cleaner. In this
   * attack there's several different chains.
   *
   *
   * The victim's gets a non-CA certificate signed by a CA, and pins the CA root and/or
   * intermediate. This is business as usual.

Aquí estamos usando `Query()` porque este es un **parámetro de query**. Más adelante veremos otros como `Path()`, `Body()`, `Header()`, y `Cookie()`, que también aceptan los mismos argumentos que `Query()`.

## Загальний огляд { #global-view }

Спочатку швидко подивімося на частини, що відрізняються від прикладів у головному **Навчальному посібнику - Керівництві користувача** для [OAuth2 з паролем (і хешуванням), Bearer з JWT-токенами](../../tutorial/security/oauth2-jwt.md). Тепер із використанням OAuth2 scopes:

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,9,13,47,65,106,108:116,122:126,130:136,141,157] *}

/// info | 信息

在 OAuth2 中，“作用域”只是一个声明所需特定权限的字符串。

是否包含像 `:` 这样的字符，或者是不是一个 URL，并不重要。

这些细节取决于具体实现。

对 OAuth2 而言，它们都只是字符串。

## 全局纵览 { #global-view }

首先，让我们快速看看与**用户指南**中 [OAuth2 实现密码（含哈希）、Bearer + JWT 令牌](../../tutorial/security/oauth2-jwt.md) 示例相比有哪些变化。现在开始使用 OAuth2 作用域：

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,9,13,47,65,106,108:116,122:126,130:136,141,157] *}

下面我们逐步回顾这些更改。

Ici nous utilisons `Query()` parce qu’il s’agit d’un **paramètre de requête**. Plus tard nous verrons d’autres comme `Path()`, `Body()`, `Header()` et `Cookie()`, qui acceptent également les mêmes arguments que `Query()`.
