 * names is a distinct URL and they are not interchangeable. For example, even if
 * `http://square.github.io/dagger` and `http://google.github.io/dagger` are served by the same IP
 * address, the two URLs identify different resources.

 * ### Port
 *
 * The port used to connect to the web server. By default this is 80 for HTTP and 443 for HTTPS.

# 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：

```

	quarkus/extensions/kubernetes-service-binding/runtime/pom.xml
quarkus/extensions/spring-web/core/deployment/pom.xml
	quarkus/extensions/spring-web/core/runtime/pom.xml
	quarkus/extensions/spring-di/deployment/pom.xml
	quarkus/extensions/spring-web/resteasy-classic/deployment/pom.xml
	quarkus/extensions/spring-web/resteasy-reactive/deployment/pom.xml
	quarkus/extensions/jaxrs-spi/deployment/pom.xml

`token_type`이 있어야 합니다. 여기서는 "Bearer" 토큰을 사용하므로 토큰 유형은 "`bearer`"여야 합니다.

그리고 액세스 토큰을 포함하는 문자열과 함께 `access_token`이 있어야 합니다.

이 간단한 예제에서는 완전히 안전하지 않고, 동일한 `username`을 토큰으로 반환합니다.

/// 팁

다음 장에서는 패스워드 해싱 및 <abbr title="JSON Web Tokens">JWT</abbr> 토큰을 사용하여 실제 보안 구현을 볼 수 있습니다.

하지만 지금은 필요한 세부 정보에 집중하겠습니다.

* The frontend stores that token temporarily somewhere.
* The user clicks in the frontend to go to another section of the frontend web app.
* The frontend needs to fetch some more data from the API.
    * But it needs authentication for that specific endpoint.
