【中文标题】带有oauth2 sso和angular 2 CORS问题的spring zuul网关【英文标题】:spring zuul gateway with oauth2 sso and angular 2 CORS issue 【发布时间】:2017-06-16 17:55:54 【问题描述】:您好,我的微服务 sso 设置存在 CORS 问题,但我无法弄清楚原因。我的设置:
oauth 微服务端口 8899:
@Configuration
@Order(-20)
public class EndpointSecurityConfig extends WebSecurityConfigurerAdapter
private AuthenticationManager authenticationManager;
@Autowired
public EndpointSecurityConfig(AuthenticationManager authenticationManager)
this.authenticationManager = authenticationManager;
@Override
public void configure(HttpSecurity http) throws Exception
// @formatter:off
http
.formLogin()
.loginPage("/login")
.usernameParameter("name")
.loginProcessingUrl("/login.do").permitAll()
.and()
.requestMatchers().antMatchers("/login", "/login.do", "/oauth/authorize", "/oauth/confirm_access")
.and()
.authorizeRequests().anyRequest().authenticated();
// @formatter:on
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception
auth.parentAuthenticationManager(authenticationManager);
PrincipalRestController
@RestController
public class PrincipalRestController
@RequestMapping("/principal")
Principal principal(Principal principal)
return principal;
zuul网关8765端口:
@SpringBootApplication
@EnableEurekaClient
@EnableZuulProxy
@EnableOAuth2Sso
@EnableAutoConfiguration
@EnableFeignClients
public class GatewayApplication extends WebSecurityConfigurerAdapter
public static void main(String[] args)
SpringApplication.run(GatewayApplication.class, args);
@Override
protected void configure(HttpSecurity http) throws Exception
// @formatter:off
http
.logout().and()
.authorizeRequests()
.antMatchers("/index.html", "/**/*.js", "/", "/login").permitAll()
.anyRequest().authenticated()
.and()
.csrf()
.csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
// @formatter:on
zuul 配置:
server:
port: 8765
spring:
aop:
proxy-target-class: true
security:
basic:
enabled: false
oauth2:
user:
password: none
client:
accessTokenUri: http://localhost:8899/uaa/oauth/token
userAuthorizationUri: http://localhost:8899/uaa/oauth/authorize
clientId: client
clientSecret: secret
resource:
userInfoUri: http://localhost:8899/uaa/principal
preferTokenInfo: false
zuul:
routes:
adminPortal:
url: http://localhost:4200
path: /**
user:
url: http://localhost:8899/uaa/principal
angular 2 应用程序端口 4200 位于网关后面:
服务
@Injectable()
export class LoginService
constructor (private http: Http)
getLoggedInUser() : Observable<LoggedInUser>
var authHeader = new Headers();
authHeader.append( "X-Requested-With", "XMLHttpRequest" );
return this.http.get("/user",
headers: authHeader
)
.map((res:Response) => res.json())
.catch((error:any) => Observable.throw(error.json().error || 'Server error'));
logout() : Observable<LoggedInUser>
var authHeader = new Headers();
authHeader.append( "X-Requested-With", "XMLHttpRequest" );
return this.http.post("/logout",,headers: authHeader)
.map((res:Response) => res.json())
.catch((error:any) => Observable.throw(error.json().error || 'Server error'));
组件
@Component(
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.sass'],
providers: [ LoginService ]
)
export class AppComponent
loggedInUser: LoggedInUser;
constructor(
private loginService: LoginService
)
this.getLoggedInUser();
getLoggedInUser()
// Get all comments
this.loginService.getLoggedInUser()
.subscribe(
loggedInUser => this.loggedInUser = loggedInUser,
err =>
console.log(err);
);
logout()
this.loginService.logout()
.subscribe(
loggedInUser => this.loggedInUser = loggedInUser,
err =>
console.log(err);
);
因此,如果我转到浏览器并打开 localhost:8765/ 请求将植根于执行 getLoggedInUser() 调用的主 angular2 页面。这将转到“localhost:8765/user”,因为在此阶段用户未登录,此调用按预期失败并出现 302,但随后自动重定向到登录也会抛出 302,然后使用 302 执行链中的其他调用。在此同时控制台显示
XMLHttpRequest 无法加载 http://localhost:8899/uaa/oauth/authorize?client_id=client&redirect_uri=http://localhost:8765/login&response_type=code&state=woE3Yc。从“http://localhost:8899/uaa/oauth/authorize?client_id=client&redirect_uri=http://localhost:8765/login&response_type=code&state=woE3Yc”重定向到“http://localhost:8899/uaa/login”已被 CORS 策略阻止:请求的资源上不存在“Access-Control-Allow-Origin”标头。 Origin 'http://localhost:8765' 因此不允许访问。
所有这些都在下图中展示:
【问题讨论】:
添加一个允许访问其他站点的标题。 谢谢@RomanC 你可以给我一个这样做的例子吗? 【参考方案1】:在您的 Spring 应用程序中配置 CORS:https://spring.io/guides/gs/rest-service-cors/
或此文档链接 https://spring.io/blog/2015/06/08/cors-support-in-spring-framework#javaconfig
【讨论】:
是的,我阅读了这篇文章,但没有成功,我在下面添加了代码:@Bean public WebMvcConfigurer corsConfigurer() return new WebMvcConfigurerAdapter() '@Override' public void addCorsMappings(CorsRegistry registry) registry. addMapping("/**").allowedOrigins("localhost:8765"); ; 试试.allowedOrigins("*")
或.allowedOrigins("http://localhost:8765")
是的,对不起,我之前的回答很匆忙,我确实放了“.allowedOrigins('localhost:8765')”,现在我什至尝试了 .allowedOrigins("*") 这个同样的问题:/ 哈哈 github 正在删除 http: )
您的意思是,您在服务器 localhost:8899
中启用了 CORS,如我所见,您在 8899 和 8765 端口有 2 台服务器
是的,我在 8899 oauth 服务器中添加了 > @Bean public WebMvcConfigurer corsConfigurer() return new WebMvcConfigurerAdapter() '@Override' public void addCorsMappings(CorsRegistry registry) registry.addMapping("/** ").allowedOrigins("localhost:8765"); ; 以上是关于带有oauth2 sso和angular 2 CORS问题的spring zuul网关的主要内容,如果未能解决你的问题,请参考以下文章
