With this feature from **Pydantic v2**, your API documentation is more **precise**, and if you have autogenerated clients and SDKs, they will be more precise too, with a better **developer experience** and consistency. 🎉

## Do not Separate Schemas { #do-not-separate-schemas }

Now, there are some cases where you might want to have the **same schema for input and output**.

- Is small, focused, and easy to review—ideally one commit, unless multiple commits better narrate complex work.
- Adheres to MinIO’s coding standards (e.g., Go style, error handling, testing).

PRs must flow smoothly through review to reach production. Large PRs should be split into smaller, manageable ones.

	  #     value: "image/*" # match objects with 'content-type', with all values starting with 'image/'

	notify:
	  endpoint: "https://notify.endpoint" # notification endpoint to receive job status events
	  token: "Bearer xxxxx" # optional authentication token for the notification endpoint

	retry:
	  attempts: 10 # number of retries for the job before giving up
	  delay: "500ms" # least amount of delay between each retry
```

            if (null == value) {
                processConfiguration(lookup, bean, loader, configuration, evaluator, listener);
            } else {

# OAuth2 实现密码哈希与 Bearer  JWT 令牌验证

至此，我们已经编写了所有安全流，本章学习如何使用 <abbr title="JSON Web Tokens">JWT</abbr> 令牌（Token）和安全密码哈希（Hash）实现真正的安全机制。

本章的示例代码真正实现了在应用的数据库中保存哈希密码等功能。

接下来，我们紧接上一章，继续完善安全机制。

## JWT 简介

JWT 即**JSON 网络令牌**（JSON Web Tokens）。

JWT 是一种将 JSON 对象编码为没有空格，且难以理解的长字符串的标准。JWT 的内容如下所示：

```

        // Add multiple headers
        request.header("Accept", "application/json").header("Content-Type", "application/json").header("Authorization", "Bearer token123")
                .header("X-Custom-Header", "custom-value");

        assertNotNull(request);
    }

    @Test
    public void testGzipSetsCompressionToGzip() {

        the time to discuss them in detail will make it much clearer why this feature should be
        added to Guava.


        Please fill out the following fields to give us a better understanding of your proposed
        feature and its potential value for other Guava users.

  - type: textarea
    attributes:
      label: 1. What are you trying to do?
    validations:
      required: true

Но тогда будут разрешены только некоторые виды взаимодействия, и всё, что связано с учётными данными, будет исключено: куки, HTTP-заголовки Authorization, как при использовании Bearer-токенов, и т.п.

Поэтому, чтобы всё работало корректно, лучше явно указывать список разрешённых источников.

## Использование `CORSMiddleware` { #use-corsmiddleware }

Pero eso solo permitirá ciertos tipos de comunicación, excluyendo todo lo que implique credenciales: Cookies, headers de autorización como los utilizados con Bearer Tokens, etc.

Así que, para que todo funcione correctamente, es mejor especificar explícitamente los orígenes permitidos.

## Usa `CORSMiddleware` { #use-corsmiddleware }
