服务间通信的授权码授权类型

使用OAuth 2.0的授权码授权类型实现服务间通信。

服务A向服务B发送请求时，服务B需要验证该请求是否经过了授权。服务B向服务A返回一个授权码(code)，服务A再使用该授权码获取访问令牌(access token)。授权码仅能使用一次，使用后即失效。

以下是一个使用Java和Spring Boot实现服务A向服务B发送验证请求的代码示例：

1. 添加依赖

<dependency> <groupId>org.springframework.security.oauth.boot</groupId> <artifactId>spring-security-oauth2-autoconfigure</artifactId> <version>2.1.2.RELEASE</version> </dependency>

2. 配置application.yml

security: oauth2: client: client-id: xxx client-secret: xxx access-token-uri: xxx user-authorization-uri: xxx token-name: aaaa grant-type: authorization_code

3. 发送验证请求

import org.springframework.http.HttpEntity; import org.springframework.http.HttpHeaders; import org.springframework.http.HttpMethod; import org.springframework.http.ResponseEntity; import org.springframework.security.oauth2.client.OAuth2RestTemplate; import org.springframework.security.oauth2.client.token.grant.code.AuthorizationCodeResourceDetails; import org.springframework.web.client.RestTemplate;

AuthorizationCodeResourceDetails resource = new AuthorizationCodeResourceDetails(); resource.setAccessTokenUri("xxx"); resource.setUserAuthorizationUri("xxx"); resource.setClientId("xxx"); resource.setClientSecret("xxx"); resource.setGrantType("authorization_code"); resource.setTokenName("aaaa");

OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(resource, null); String url = "xxx"; HttpHeaders headers = new HttpHeaders(); headers.add("Authorization", "Bearer " + accessToken); HttpEntity<String> entity = new HttpEntity<>(headers);

ResponseEntity<String> response = restTemplate.exchange( url, HttpMethod.GET, entity, String.class);

注意：以上示例中的xxx应替换为实际的值。
