java - 已被 CORS 策略阻止 : Response to preflight request doesn't pass

Question

我已经使用 Angular 和 SpringBoot 创建了一个应用程序，用于 Spring Security 的基本身份验证，但我收到 401 错误..我是 SpringBoot 新手

@Configuration
@EnableWebSecurity
public class SpringSecurityConfigurationBasicAuth extends WebSecurityConfigurerAdapter{ 

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .authorizeRequests()
            .antMatchers(HttpMethod.OPTIONS,"/**").permitAll()
                .anyRequest().authenticated()
                .and()
            //.formLogin().and()
            .httpBasic();
    }
}

"Access to XMLHttpRequest at 'http://localhost:8080/hello-world/path-variable/MSD' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status."

我在 anglat7 和 spring boot 上也遇到了同样的问题，我通过添加以下配置解决了

 @Configuration
    public class SpringDataRestConfiguration extends RepositoryRestConfigurerAdapter {

        @Override
        public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {

        config.getCorsRegistry().addMapping("/**").allowedOrigins("*").allowedHeaders("*").allowedMethods("GET", "POST", "PATCH", "PUT", "DELETE");
        }

    }
