【问题描述】：
我正在尝试使用 Spring OAuth2 在我的 Spring webapp 的 Facebook 上实现注册阶段。我正在关注本指南https://www.callicoder.com/spring-boot-security-oauth2-social-login-part-2/，但我的代码中的某些内容无法按预期工作。 OAuth2User 类型的对象在属性中只有 facebook 帐户的 id 和名称。
特别是在@Service 类中CustomOAuth2UserService 方法中processOAuth2User
private OAuth2User processOAuth2User(OAuth2UserRequest oAuth2UserRequest, OAuth2User oAuth2User) {
OAuth2UserInfo oAuth2UserInfo = OAuth2UserInfoFactory.getOAuth2UserInfo(oAuth2UserRequest.getClientRegistration().getRegistrationId(), oAuth2User.getAttributes());
if(StringUtils.isEmpty(oAuth2UserInfo.getEmail())) {
throw new OAuth2AuthenticationProcessingException("Email not found from OAuth2 provider");
}
...
}
oAuth2User.getAttributes()，正如我所说，只有两个属性：id 和 name，但没有 email。
我的 CustomOAuth2UserService 类是这样的：
@Service
public class CustomOAuth2UserService extends DefaultOAuth2UserService {
@Autowired
private UserService userService;
@Override
public OAuth2User loadUser(OAuth2UserRequest oAuth2UserRequest) throws OAuth2AuthenticationException {
OAuth2User oAuth2User = super.loadUser(oAuth2UserRequest);
try {
return processOAuth2User(oAuth2UserRequest, oAuth2User);
} catch (AuthenticationException ex) {
throw ex;
} catch (Exception ex) {
// Throwing an instance of AuthenticationException will trigger the OAuth2AuthenticationFailureHandler
throw new InternalAuthenticationServiceException(ex.getMessage(), ex.getCause());
}
}
private OAuth2User processOAuth2User(OAuth2UserRequest oAuth2UserRequest, OAuth2User oAuth2User) {
OAuth2UserInfo oAuth2UserInfo = OAuth2UserInfoFactory.getOAuth2UserInfo(oAuth2UserRequest.getClientRegistration().getRegistrationId(), oAuth2User.getAttributes());
if(StringUtils.isEmpty(oAuth2UserInfo.getId())) {
throw new RuntimeException("Id not found from OAuth2 provider");
}
FacebookUser user = null;
try {
user = (FacebookUser) userService.getByFacebookId(oAuth2UserInfo.getId());
} catch (UserNotFoundException e) {
user = registerNewUser(oAuth2UserRequest, oAuth2UserInfo);
}
return new CustomUserDetails(user);
}
private FacebookUser registerNewUser(OAuth2UserRequest oAuth2UserRequest, OAuth2UserInfo oAuth2UserInfo) {
FacebookUser user = new FacebookUser(oAuth2UserInfo.getId());
user.setProvider(AuthProvider.valueOf(oAuth2UserRequest.getClientRegistration().getRegistrationId()));
user.setIdentity(new Identity(oAuth2UserInfo.getName()));
user.setEmail(oAuth2UserInfo.getEmail());
return (FacebookUser) userService.addFacebookUser(user);
}
}
在 SecurityConfiguration 类中插入：
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableWebSecurity
@EnableJpaRepositories(basePackageClasses = UserRepository.class)
@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Autowired
private CustomOAuth2UserService customOAuth2UserService;
@Autowired
private CustomUserDetailsService userDetailsService;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
super.configure(auth);
auth
.userDetailsService(userDetailsService)
.passwordEncoder(passwordEncoder());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.formLogin()
.loginPage("/login")
.failureUrl("/login?error=true")
.and()
.oauth2Login()
.loginPage("/login")
.userInfoEndpoint()
.userService(customOAuth2UserService);
}
}
