Spring Boot中的CORS

Question

我正在尝试使用cors配置来设置我的服务器应用程序。这里的配置，但login上的任何cors请求将有一个403响应代码：

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    private final JwtAuthenticationEntryPoint unauthorizedHandler;

    @Autowired
    public WebSecurityConfig(JwtAuthenticationEntryPoint unauthorizedHandler) {
        this.unauthorizedHandler = unauthorizedHandler;
    }

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(Collections.singletonList("*"));
        configuration.setAllowedMethods(Collections.singletonList("*"));
        configuration.setAllowedHeaders(Collections.singletonList("*"));
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.addFilterBefore(new JwtAuthenticationTokenFilter(), UsernamePasswordAuthenticationFilter.class)
            .cors().and()
            .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
            .csrf().disable()
            .antMatcher("/api/**").authorizeRequests()
            .antMatchers("/login/**").permitAll()
            .anyRequest().authenticated();

}

}

编辑我已经解决了添加另一个配置类并从web安全性中删除bean的问题。

请理解，必须在Spring Boot上配置cors配置，而不是在Spring Security上配置。

我要添加的课程是：

@Configuration
public class CorsConfig implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {

         registry.addMapping("/**")
            .allowedOrigins("*")
            .allowedMethods("GET", "POST", "PUT", "DELETE", "HEAD")
            .allowedHeaders("*")
            .allowCredentials(true);
    }

}

WebSecurityConfig已成为：

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    private final JwtAuthenticationEntryPoint unauthorizedHandler;

    @Autowired
    public WebSecurityConfig(JwtAuthenticationEntryPoint unauthorizedHandler) {
        this.unauthorizedHandler = unauthorizedHandler;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.addFilterBefore(new JwtAuthenticationTokenFilter(), UsernamePasswordAuthenticationFilter.class)
            .cors().and()
            .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
            .csrf().disable()
            .antMatcher("/api/**").authorizeRequests()
            .antMatchers("/login/**").permitAll()
            .anyRequest().authenticated();

}

}

现在所有工作都按预期工作，在所有端点上正确管理cors

Answer 1

试试这个：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.addFilterBefore(new JwtAuthenticationTokenFilter(), UsernamePasswordAuthenticationFilter.class)
        .cors().and()
        .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
        .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
        .csrf().disable()
        .antMatcher("/api/**").authorizeRequests()
        .antMatchers(HttpMethod.OPTIONS,"/login/**").permitAll() // this
        .anyRequest().authenticated();

Answer 2

试试这个吧

@Override
public void addCorsMappings(CorsRegistry registry) {
    registry.addMapping("/**") //or the URLs you would like to add
            .allowedMethods("GET", "POST");
}
