Spring Security Oauth2 Authorization Server

- github仓库地址: https://github.com/spring-projects/spring-authorization-server/
- 官方示例代码地址： https://github1s.com/spring-projects/spring-authorization-server/blob/main/samples/
- oauth2文档地址：http://www.rfcreader.com/#rfc6749

```java
// 令牌管理服务
OAuth2AuthorizationService oAuth2AuthorizationService;
// 默认sql脚本路径
// org/springframework/security/oauth2/server/authorization/oauth2-authorization-schema.sql

// 客户端id、用户名与权限关联关系管理
OAuth2AuthorizationConsentService oAuth2AuthorizationConsentService;
// 默认sql脚本路径
// org/springframework/security/oauth2/server/authorization/oauth2-authorization-consent-schema.sql

// 客户端管理服务
RegisteredClientRepository registeredClientRepository;
// 默认sql脚本路径
// org/springframework/security/oauth2/server/authorization/client/oauth2-registered-client-schema.sql
```

#### 端点 参见auth-server/test/java/test.http

##### 根据用户名密码获取令牌

```http
###
# 根据用户名密码获取令牌
POST http://localhost:9000/oauth2/token
Authorization: Basic bWVzc2FnaW5nLWNsaWVudDpzZWNyZXQ=
Accept-Language: zh_CN
Content-Type: application/x-www-form-urlencoded

grant_type=password&username=admin&password=123456
```

##### 使用访问令牌访问资源服务器

```http
###
# 访问资源服务器
GET http://localhost:8090/messages
Authorization: Bearer eyJraWQiOiIzOTIzMzQyNy02Zjc3LTRmODAtYWY1YS1kMGY1ZDFlZGZmMDkiLCJhbGciOiJSUzI1NiJ9.eyJzdWIiOiJtZXNzYWdpbmctY2xpZW50IiwiYXVkIjoibWVzc2FnaW5nLWNsaWVudCIsIm5iZiI6MTY0MTM2NjYyNSwic2NvcGUiOlsib3BlbmlkIiwibWVzc2FnZS5yZWFkIiwibWVzc2FnZS53cml0ZSJdLCJpc3MiOiJodHRwOlwvXC9sb2NhbGhvc3Q6OTAwMCIsImV4cCI6MTY0MTM2NjkyNSwiaWF0IjoxNjQxMzY2NjI1fQ.PfY2EC55as3Kboem6Dn5NaIaBxdiBmW63riIFBILEGD6WUf85jVJVblNYyf9_TSkoXpGqrOqbQppWOAfQrQQsQJF_3SxFcn9_uPrtFujGeuwSvc9U2Zc6ZfoUBEqI67Emu2gJtjvjXJZuc0PSXrekFYZOUM3VzbYsoC1Ey8jjM-jD9lBxDFjyt1Um2v0pCCPyJfOJB_vXE4pgiUzZQaEwrJVGIZWXWwyGb72J4OuWeCQZCXs6hlIVMvvvNROJKVNaBg3_En__9lI7VAPa5b17YWAz-6qQxtjFcBbXoWBvDWffoGU2mbegMxiYS9R_BVeNCJidTPT0C7TaVozbLngAA

```

##### 获取授权码

```http
###
# 获取授权码  scope参数可以为空，不为空且consentAuthorization时则需要跳转至授权同意页面

http://localhost:9000/oauth2/authorize?client_id=messaging-client&client_secret=secret&response_type=code&scope=message.write&redirect_uri=http://127.0.0.1:8080/login/oauth2/code/messaging-client-oidc
```

是否需要授权同意判断逻辑源码

```java
// OAuth2AuthorizationCodeRequestAuthenticationProvider.requireAuthorizationConsent()
	private static boolean requireAuthorizationConsent(RegisteredClient registeredClient,
			OAuth2AuthorizationRequest authorizationRequest, OAuth2AuthorizationConsent authorizationConsent) {
		// 客户端不需要授权同意则直接false
		if (!registeredClient.getClientSettings().isRequireAuthorizationConsent()) {
			return false;
		}
		// 'openid' scope does not require consent
		if (authorizationRequest.getScopes().contains(OidcScopes.OPENID) &&
				authorizationRequest.getScopes().size() == 1) {
			return false;
		}
		// 如果授权同意不为空，并且当前请求的scope在其授权范围内
        // todo scope参数为空
		if (authorizationConsent != null &&
		authorizationConsent.getScopes().containsAll(authorizationRequest.getScopes())) {
			return false;
		}

return true;
	}
```

##### 根据授权码获取令牌

```http
###
# 根据授权码获取刷新令牌
POST http://localhost:9000/oauth2/token
Authorization: Basic bWVzc2FnaW5nLWNsaWVudDpzZWNyZXQ=
Accept-Language: zh_CN
Content-Type: application/x-www-form-urlencoded

grant_type=authorization_code&code=KIhCcynyLhWFFAaKFOlda_Cs3HxJW_okrJxhB0BgtKziDk3Hc_J2dLcAnPs7h2NaWYfs0-fQQCs9D0_vWYf9OJ7Lxlmc5RScbNCzrtKKDeIrBiNsQlz8Kw7vWpsau47Y&redirect_uri=http://127.0.0.1:8080/login/oauth2/code/messaging-client-oidc
```

##### 根据刷新令牌重置访问与刷新令牌

```http
###
# 根据刷新令牌重置访问与刷新令牌
POST http://localhost:9000/oauth2/token
Authorization: Basic bWVzc2FnaW5nLWNsaWVudDpzZWNyZXQ=
Accept-Language: zh_CN
Content-Type: application/x-www-form-urlencoded

grant_type=refresh_token&refresh_token=gvSnvJbpBbxT-FP70ROrwRDxADasERy1ps010LTvaoA2_tiQoWT6SekfbXjLnQmjofe9be-OfKAJPlku37hQT4jd3RlxbiSwLpyEJFfF_JselGf_y-NTwv7iGWaQaRFm
```

##### 撤销令牌

```http
POST http://localhost:9000/oauth2/revoke
Authorization: Basic bWVzc2FnaW5nLWNsaWVudDpzZWNyZXQ=
Accept-Language: zh_CN
Content-Type: application/x-www-form-urlencoded

# token_type_hint 参数可选
token_type_hint=access_token&token=xxx
或
token_type_hint=refresh_token&token=xxx
```

##### 获取令牌信息

```http
###
# 获取访问/刷新令牌信息
POST http://localhost:9000/oauth2/introspect
Authorization: Basic bWVzc2FnaW5nLWNsaWVudDpzZWNyZXQ=
Accept-Language: zh_CN
Content-Type: application/x-www-form-urlencoded

# token_type_hint 参数可选
token_type_hint=access_token&token=xxx
或
token_type_hint=refresh_token&token=xxx
```

#### 授权客户端使用流程
```
授权代码流程经过以下步骤。

客户端准备一个包含所需请求参数的身份验证请求。
客户端将请求发送到授权服务器。
授权服务器对最终用户进行身份验证。
授权服务器获得最终用户同意/授权。
授权服务器使用授权码将最终用户发送回客户端。
客户端使用令牌端点处的授权码请求响应。
客户端收到响应正文中包含 ID Token 和 Access Token 的响应。
客户端验证 ID 令牌并检索最终用户的主题标识符。

# 访问 http:localhost:8080 跳转至index页面 点击 Authorization Code 发起授权码登陆流程

1.由OAuth2AuthorizedClientArgumentResolver#resolveArgument 解析 @RegisteredOAuth2AuthorizedClient注解 组装 OAuth2AuthorizeRequest
2.OAuth2AuthorizedClientManager#authorize 将 OAuth2AuthorizeRequest 转换为 OAuth2AuthorizationContext 
3.OAuth2AuthorizedClientProvider#authorize 调用 
    OAuth2AccessTokenResponseClient#getTokenResponse 向授权服务器发起请求 `http://localhost:9000/oauth2/token`获取 OAuth2AccessTokenResponse
    并将OAuth2AccessTokenResponse 回填至 OAuth2AuthorizedClient参数中
4.然后使用webclient将获取到的OAuth2AuthorizedClient作为请求参数调用资源服务器
