RemoteTokenServices 是 Spring Security OAuth2 提供的一个接口,用于从远程 OAuth2 授权服务器验证访问令牌(access token)并返回相关的信息。下面是 RemoteTokenServices 的使用方法:
1. 添加依赖:在 Maven 中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.security.oauth</groupId>
<artifactId>spring-security-oauth2</artifactId>
<version>2.3.4.RELEASE</version>
</dependency>
```
2. 实现 RemoteTokenServices 接口:创建一个类实现 RemoteTokenServices 接口,并实现其 loadAuthentication(String accessToken) 方法,该方法应该从授权服务器验证访问令牌并返回相关的信息。
```java
@Service
public class CustomRemoteTokenServices implements RemoteTokenServices {
@Autowired
private RestTemplate restTemplate;
@Override
public OAuth2Authentication loadAuthentication(String accessToken) throws AuthenticationException, InvalidTokenException {
// 构造请求头
HttpHeaders headers = new HttpHeaders();
headers.set("Authorization", "Bearer " + accessToken);
HttpEntity<?> entity = new HttpEntity<>(headers);
// 发送请求
ResponseEntity<Map> responseEntity = restTemplate.exchange("http://localhost:8080/oauth/check_token?token=" + accessToken, HttpMethod.GET, entity, Map.class);
// 解析响应
if (responseEntity.getStatusCode() == HttpStatus.OK) {
Map<String, Object> responseMap = responseEntity.getBody();
if (responseMap.containsKey("error")) {
throw new InvalidTokenException(accessToken);
}
else {
// 构造身份验证信息
return new OAuth2Authentication(extractAuthentication(responseMap), extractAuthenticationDetails(responseMap));
}
}
else {
throw new AuthenticationServiceException("Authentication server response: " + responseEntity.getStatusCode());
}
}
// 提取身份验证信息
private Authentication extractAuthentication(Map<String, Object> map) {
// TODO: 提取身份验证信息
return null;
}
// 提取身份验证细节
private OAuth2AuthenticationDetails extractAuthenticationDetails(Map<String, Object> map) {
// TODO: 提取身份验证细节
return null;
}
}
```
3. 配置 RemoteTokenServices:在 Spring Security 配置文件中配置 RemoteTokenServices,以便使用它从远程授权服务器验证访问令牌。
```java
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Autowired
private CustomRemoteTokenServices customRemoteTokenServices;
@Override
public void configure(ResourceServerSecurityConfigurer resources) {
resources.tokenServices(customRemoteTokenServices);
}
// ...
}
```
这样就可以使用 RemoteTokenServices 从远程 OAuth2 授权服务器验证访问令牌了。注意:需要根据实际情况修改代码中的 URL、请求头和响应解析逻辑等部分。
