谷粒商城day33 -API-三级分类-网关统一配置跨域

1.了解跨域

 

 

2.跨域过滤器添加

网关服务内添加如下代码

允许所有路径请求跨域 ,添加过滤器到容器中，因为所有请求都要经过网关，所以该过滤器配置代码添加到网关中

package com.atguigu.gulimall.gateway.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.reactive.CorsWebFilter;
import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource;

@Configuration
public class GulimallCorsConfiguration {

    @Bean
    public CorsWebFilter corsWebFilter(){
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        //配置跨域
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.setAllowCredentials(true);

        UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource
                = new UrlBasedCorsConfigurationSource();
        urlBasedCorsConfigurationSource.registerCorsConfiguration("/**",corsConfiguration);
        return new CorsWebFilter(urlBasedCorsConfigurationSource);
    }
}
