gateway网关跨域配制

一、java类配制

@Bean
public CorsFilter corsFilter() {
    logger.debug ("CORS限制打开");
    CorsConfiguration config = new Corsconfiguration();#仅在开发环境设置为*
    config.addAllowedorigin( "*");
    config.addAllowedHeader("*");
    config.addAllowedMethod("*" );
    config.setAllowCredentials(true);
    UrlBasedCorsConfigurationSource configSource = new UrlBasedCorsConfigurationSource();
    configSource.registerCorsConfiguration ( "/**",config);
    return new CorsFilter(configsource);

二、yml配制
前端页面通过不同域名或IP访问SpringCloud Gateway,例如前端人员在本地起HttpServer直连服务器的Gateway进行调试。此时,同样会遇到跨域。需要在Gateway的配置文件中增加:

spring:
  cloud :
    gateway:
      globalcors:
        cors-configurations:
        #仅在开发环境设置为*
          '[ /**] ':
            allowedOrigins: "*"
            allowedHeaders: "*"
            allowedMethods: "*"
