CORS 预检通道未成功 Spring 安全

Question

我正在构建一个带有 Spring 引导后端的 Angular 2 应用程序。几天来，我一直在尝试解决 CORS 预检的问题。根据这个，它应该像这样使用 CORS 过滤器：

@Component
public class CorsFilter extends OncePerRequestFilter {

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "authorization, content-type, xsrf-token");
        response.addHeader("Access-Control-Expose-Headers", "xsrf-token");
        if ("OPTIONS".equals(request.getMethod())) {
            response.setStatus(HttpServletResponse.SC_OK);
        } else { 
            filterChain.doFilter(request, response);
        }
    }
}


@Configuration
@EnableResourceServer
public class ResourceServerConfiguration extends    ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
        .addFilterBefore(new CorsFilter(), ChannelProcessingFilter.class)
        .headers()
            .frameOptions().disable()
            .and()
        .authorizeRequests()
            .antMatchers("/", "/home", "/register", "/login").permitAll()
            .antMatchers("/cottages").authenticated();
    }
}

Angular 前端：

  import {Injectable} from '@angular/core';
  import {Headers, Http} from "@angular/http";
  import {AppSettings} from "../app.settings";
  import { URLSearchParams } from '@angular/http'

  import {User} from "../_models/_index";
  import {Observable} from "rxjs";

  @Injectable()
  export class AuthenticationService {
   private headers = new Headers({'Content-Type': 'application/json'});
  private tokenHeaders = new Headers({
 'Content-Type': 'application/json',
 'client_id': 'xxx',
 'client_secret': 'xxx'});


constructor(private http: Http) {
}


login(user: User) {
let urlSearchParams = new URLSearchParams();
urlSearchParams.append('username', user.username);
urlSearchParams.append('password', user.password);
let body = urlSearchParams.toString();

return this.http.post(AppSettings.getApiUrl() + "oauth/token", body, { withCredentials: true, headers: this.tokenHeaders })
  .map((responseData) => {
    return responseData.json();
  })
  .map((item: any) => {
    return new User(item);
  })
  .catch((error: any) => Observable.of(error.json().error || 'Server error'));

 }
}

我尝试了在 this 和 Spring 文档中找到的其他配置。

我总是收到此错误消息：

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:8080/oauth/token. (Reason: CORS preflight channel did not succeed).

向我自己的控制器发出简单的 CORS 请求，例如注册用户，效果很好。

任何人都可以向我解释我做错了什么吗？我的 Java 或 Typescript 代码有错误吗？

编辑：

授权服务器配置：

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends     AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory().withClient("my-trusted-client").authorizedGrantTypes("client_credentials", "password")
            .authorities("ROLE_CLIENT", "ROLE_TRUSTED_CLIENT").scopes("read", "write", "trust")
            .resourceIds("oauth2-resource").accessTokenValiditySeconds(5000).secret("xxx");
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.checkTokenAccess("isAuthenticated()");
     }
}

Answer 1

您在请求中将 withCredentials 设置为 true，但在预检响应中缺少 Access-Control-Allow-Credentials。请参阅 here 关于 header。

return ...withCredentials: true, headers: this.tokenHeaders })


response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "authorization, content-type, xsrf-token");

response.addHeader("Access-Control-Expose-Headers", "xsrf-token");
 // add this
response.setHeader("Access-Control-Allow-Headers", "true");

我注意到您在请求中添加了一些其他头像，例如 client_id，但您没有将它们添加到 Access-Control-Allow-Headers。

Answer 2

我终于找到了解决问题的方法。双方都有几个错误（Angular/Java Spring 启动、安全）。我会 post 我的工作代码在这里解释一下。我将从后端开始：

@Configuration
@EnableWebSecurity
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {


@Override
public void configure(HttpSecurity http) throws Exception {
    http
    .authorizeRequests()
    .antMatchers("/", "/users").permitAll().anyRequest()
    .authenticated()
    .and()
    .csrf().disable()

}
}

根据 spring.io 教程，WebSecurityConfiguration 是我工作的更好选择 - 它也适用于 ResourceServerConfiguration。老实说，我不知道有什么区别（当我必须使用这个和另一个时）。

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

public SimpleCorsFilter() {
}

@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", "*");
    response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
    response.setHeader("Access-Control-Max-Age", "3600");
    response.setHeader("Access-Control-Allow-Headers", "x-requested-with, authorization, content-type");

    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() {
}


}

没有这个 CorsFilter，我只能从服务器获得 OPTIONS 响应。

我没有更改上面 post 编辑的 AuthorizationServerConfiguration。

实际上大多数错误都在 Angular / 前端。这对我有用：

@Injectable()
export class AuthenticationService {

private headers = new Headers({'Content-Type': 'application/json'});

private auth64 = btoa("my-trusted-client:secret");
private tokenHeaders = new Headers({
'Content-Type': 'application/x-www-form-urlencoded',
'Authorization': 'Basic '+this.auth64
});


constructor(private http: Http) {
 }


login(user: User) {
let body = new URLSearchParams();
body.append('grant_type', 'password');
body.append('username', user.username);
body.append('password', user.password);

return this.http.post(AppSettings.getApiUrl() + "oauth/token", body, {headers: this.tokenHeaders})
  .map(data => {
    console.log("it works!");
  }, error => {
    console.log(error.json());
  });

 }

之前的映射有问题。它总是导致预检 CORS 问题。我没有收到此映射的预检错误消息 - 即使我不使用 CORS 过滤器 - 但您需要 CORS 过滤器才能从服务器获取 OPTIONS 响应以外的内容。

据此我收到以下错误消息（在 JSON 响应中）： "Full authentication is required to access this resource"

为了解决这个问题，我执行了以下步骤：

将 content-type 更改为 application/x-www-form-urlencoded（对于 oauth2 很重要）
删除 headers client_id/client_secret
添加授权headers
使用 Base64(btoa)
将编码值添加到我的授权中header

也许有 other/better 方法可以解决这些问题，但这段代码对我来说工作正常 - 也许它可以帮助这里的其他人:-)
