  • 配置Spring Boot 跨域后PUT,DELETE方法出现403Forbidden

    配置类

    @Configuration
    public class CorsConfiguration {
        @Bean
        public WebMvcConfigurer corsConfigurer() {
            return new WebMvcConfigurer() {
                @Override
                public void addCorsMappings(CorsRegistry registry) {
                    registry.addMapping("/**");
                }
            };
        }
    }

    前端请求

    错误原因:SpringBoot默认跨域方法只支持HEAD,GET,POST

    配置类修改后

    @Configuration
    public class CorsConfiguration {
        @Bean
        public WebMvcConfigurer corsConfigurer() {
            return new WebMvcConfigurer() {
                @Override
                public void addCorsMappings(CorsRegistry registry) {
                    registry.addMapping("/**")
                            .allowedOrigins("*")
                            .allowCredentials(true)
                            .allowedMethods("GET", "POST", "PUT", "DELETE");
                }
            };
        }
    }

    附相关SpringBoot部分源码

    //package org.springframework.web.cors.CorsConfiguration
    /** Wildcard representing <em>all</em> origins, methods, or headers. */
        public static final String ALL = "*";
    
        private static final List<HttpMethod> DEFAULT_METHODS = Collections.unmodifiableList(
                Arrays.asList(HttpMethod.GET, HttpMethod.HEAD));
    
        private static final List<String> DEFAULT_PERMIT_METHODS = Collections.unmodifiableList(
                Arrays.asList(HttpMethod.GET.name(), HttpMethod.HEAD.name(), HttpMethod.POST.name()));
    
        private static final List<String> DEFAULT_PERMIT_ALL = Collections.unmodifiableList(
                Collections.singletonList(ALL));


    public
    CorsConfiguration applyPermitDefaultValues() { if (this.allowedOrigins == null) { this.allowedOrigins = DEFAULT_PERMIT_ALL; } if (this.allowedMethods == null) { this.allowedMethods = DEFAULT_PERMIT_METHODS; this.resolvedMethods = DEFAULT_PERMIT_METHODS .stream().map(HttpMethod::resolve).collect(Collectors.toList()); } if (this.allowedHeaders == null) { this.allowedHeaders = DEFAULT_PERMIT_ALL; } if (this.maxAge == null) { this.maxAge = 1800L; } return this; }
