java – Spring无法配置授权服务器

发布时间：2020-12-15 02:18:44 所属栏目：Java 来源：网络整理

导读：我创建了一个简单的授权服务器,但无法配置它. 启动两个应用程序(8080用于auth服务器,9999用于客户端). 转到localhost：9999 / client并重定向到localhost：8080 / login(按预期方式). 使用用户/用户填写登录表单. 重定向到localhost：9999 / client(按预期方

但是,如果我直接访问localhost：8080 / me,我有{“name”：“user”}.如何检索Hello,用户？

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

@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);
    }

}

客户的财产

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：
当所有工作都下载时我下载了a tutorial,但它有ssoFilter仅用于OAuth2身份验证.我只想用loginForm配置它.
我还在GitHub上分享了一个临时的example.我认为用它来查找问题会更容易.

解决方法

存在不同的端口9999 8080,当它从与第一资源本身服务的域或端口不同的域或端口请求资源时,这将导致跨源HTTP请求.

有关HTTP access control (CORS)的更多详细信息

官方春季网站Enabling Cross Origin Requests for a RESTful Web Service上有一个很好的例子

我建议只需通过实现Filter接口就可以在您的应用上进行CORS过滤.

@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 app,请务必在组件扫描中包含新过滤器所在的包.

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>

选项在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>
