java - 连接到 WebSocket 时如何修复“Access-Control-Allow-Origin”错误？

问题描述

我正在开发 SockJS 和 WebSocket 类型的项目，对于前端我使用 React，在后端使用 Spring 的 WebSockets 实现。但是当我尝试连接到我的 WebSocket 时出现 CORS 错误。

Access to XMLHttpRequest at 'http://localhost:8080/ws/info?t=1579096675068' from origin 'http://localhost:3000' has been blocked by CORS policy: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

在 Java 项目中，我包含了这个 CORS 配置：

@Bean
CorsConfigurationSource corsConfigurationSource() {
     final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
     final CorsConfiguration configuration = new CorsConfiguration();
     configuration.applyPermitDefaultValues();
     configuration.setExposedHeaders(Arrays.asList("Authorization"));
     configuration.addAllowedOrigin("*");
     configuration.addAllowedMethod("*");
     configuration.addAllowedHeader("*");
     source.registerCorsConfiguration("/**", configuration);
     return source;
}

至于课堂configure上的方法，WebSecurity我已经包括了这个：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.cors().and().csrf().disable().authorizeRequests()
             .antMatchers(HttpMethod.POST, SIGN_UP_URL).permitAll()
             .anyRequest().authenticated()
             .and()
             .addFilter(new JWTAuthenticationFilter(authenticationManager()))
             .addFilter(new JWTAuthorizationFilter(authenticationManager()))
             .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}

@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
}

我像这样添加我的套接字端点：

@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
    registry.addEndpoint("/ws").setAllowedOrigins("*").withSockJS();
}

在前端，我使用一种connect方法连接到我的 WebSocket：

connect = () => {
  const Stomp = require("stompjs");
  let SockJS = require("sockjs-client");
  SockJS = new SockJS("http://localhost:8080/ws");
  stompClient = Stomp.over(SockJS);
  stompClient.connect({}, this.onConnected, this.onError);
};

我已尝试将registerStompEndpoints方法上的 URL 设置为http://localhost:3000显式设置，但没有效果。还在我package.json的前端添加了一个代理http://localhost:8080/，但它仍然给出了同样的错误。我有什么需要做的corsConfigurationSource才能让这个工作吗？

更新

当我执行以下configure方法时，它解决了 WebSocket 问题，因为它可以连接到它，但是我无法访问我的应用程序的其他路由，因为它给出了另一个错误。

protected void configure(HttpSecurity http) throws Exception {
     http.authorizeRequests()
             .antMatchers("/ws").permitAll()
             .antMatchers(HttpMethod.POST, SIGN_UP_URL).permitAll()
             .and()
             .addFilter(new JWTAuthenticationFilter(authenticationManager()))
             .addFilter(new JWTAuthorizationFilter(authenticationManager()))
     .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and().csrf().disable();
}

另一个错误：

Access to XMLHttpRequest at 'http://localhost:8080/auth/me' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

解决方案

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and()
              .authorizeRequests()
              .antMatchers("/ws/**").permitAll()
              .antMatchers(HttpMethod.POST, SIGN_UP_URL).permitAll()
              .anyRequest().authenticated()
              .and()
              .addFilter(new JWTAuthenticationFilter(authenticationManager()))
              .addFilter(new JWTAuthorizationFilter(authenticationManager()))
              .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
              .and().csrf().disable();
}

@Bean
CorsConfigurationSource corsConfigurationSource() {

        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        final CorsConfiguration configuration = new CorsConfiguration();
        configuration.setExposedHeaders(Arrays.asList("Authorization"));
        configuration.addAllowedOrigin("*");
        configuration.addAllowedMethod("*");
        configuration.addAllowedHeader("*");
        configuration.applyPermitDefaultValues();
        source.registerCorsConfiguration("/api/**", configuration);
        source.registerCorsConfiguration("/auth/*", configuration);
        source.registerCorsConfiguration("/login", configuration);
        return source;
}

我最终将其用作我的 WebSecurity。总而言之，我添加.antMatchers("/ws/**").permitAll()了我的configure方法。因此，我允许所有请求到达我的 WebSocket 端点，并在我的所有其他路由上显式注册 CORS 配置，但方法/ws上的路由除外corsConfigurationSource。希望这可以帮助。
