java - Spring无法配置授权服务器

Question

我创建了一个简单的授权服务器，但无法配置它。

1. 启动两个应用程序(8080 用于身份验证服务器，9999 用于客户端)。
2. 转到 localhost:9999/client并被重定向到 localhost:8080/login (正如预期的那样)。
3. 使用用户/用户填写登录表单。
4. 重定向到 localhost:9999/client (正如预期的那样)，但有 Hello, null而不是 Hello, user .

但是，如果我直接转到 localhost:8080/me , 我有 {"name":"user"} .如何检索 Hello, user ？

授权服务器

@RestController
@EnableAuthorizationServer
@SpringBootApplication
public class Application extends WebSecurityConfigurerAdapter {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @GetMapping({ "/user", "/me" })
    public Map<String, String> user(Principal principal) {
        return Collections.singletonMap("name", principal == null ? "null" : principal.getName());
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("user").password("user").authorities(AuthorityUtils.NO_AUTHORITIES);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin();
    }
}

应用程序的属性

security:
  oauth2:
    client:
      client-id: clientid
      client-secret: clientsecret
      scope: read,write
      auto-approve-scopes: '.*'

客户端

@Configuration
@EnableAutoConfiguration
@EnableOAuth2Sso
@RestController
public class Client {

    @GetMapping("/")
    public String home(Principal principal) {
        return "Hello, " + principal.getName();
    }

    public static void main(String[] args) {
        new SpringApplicationBuilder(Client.class)
                .properties("spring.config.name=client").run(args);
    }

}

客户的属性

server:
  port: 9999
  context-path: /client
security:
  oauth2:
    client:
      client-id: clientid
      client-secret: clientsecret
      access-token-uri: http://localhost:8080/oauth/token
      user-authorization-uri: http://localhost:8080/oauth/authorize
    resource:
      user-info-uri: http://localhost:8080/me

更新:
我下载了a tutorial当一切正常时，但它有 ssoFilter这仅适用于 OAuth2 身份验证。我只想用 loginForm 配置它.
我也分享了一个临时的 example在 GitHub 上。我认为用它查找问题会更容易。

9999 8080 不同的端口会导致cross-origin HTTP request 当它从不同域请求资源时，或第一个资源本身服务的端口。

有关的更多详细信息HTTP access control (CORS)

spring官方网站上有泥煤样例Enabling Cross Origin Requests for a RESTful Web Service

我建议通过实现 Filter 接口(interface)在您的应用上执行 CORS 过滤器。

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CorsFilter implements Filter {

    public CorsFilter() {
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        HttpServletRequest request = (HttpServletRequest) req;
        response.setHeader("Access-Control-Allow-Origin", "*"); //for production add only origins which should be allowed to access now for demo purposes this accepts all.
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE"); //i would reduce this method list if not all methods used this is added just for demo purposes
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with, authorization");

        if ("OPTIONS".equalsIgnoreCase(request.getMethod())) {
            response.setStatus(HttpServletResponse.SC_OK);
        } else {
            chain.doFilter(req, res);
        }
    }

    @Override
    public void init(FilterConfig filterConfig) {
    }

    @Override
    public void destroy() {
    }
}

如果您使用的是 spring boot 应用程序，那么请务必包含您的新过滤器在组件扫描中创建的包。

如果您使用“web.xml”进行配置:

然后添加过滤器

<filter>
    <filter-name>CORS</filter-name>
    <filter-class>com.mycompany.CorsFilter</filter-class>
</filter>

选项 A 在您的 servlet 上添加映射

<filter-mapping>
        <filter-name>CORS</filter-name>
        <servlet-name>MyServlet</servlet-name>
</filter-mapping>

选项B为所有应用添加过滤器:

<filter-mapping>
        <filter-name>CORS</filter-name>
        <url-pattern>/*</url-pattern> <!--this will add cors on all apps-->
</filter-mapping>
