后端代码配置

通过yml配置的方式

https://docs.spring.io/spring-cloud-gateway/docs/current/reference/html/#cors-configuration

spring:
  cloud:
    gateway:
        globalcors:
          cors-configurations:
            '[/**]':
              allowedOrigins: "*"
              allowedMethods:
              - GET
              - POST
              - DELETE
              - PUT
              - OPTION

通过java配置的方式

@Configuration
public class CorsConfig {
    @Bean
    public CorsWebFilter corsFilter() {
        CorsConfiguration config = new CorsConfiguration();
        config.addAllowedMethod("*");
        config.addAllowedOrigin("*");
        config.addAllowedHeader("*");
 
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(new PathPatternParser());
        source.registerCorsConfiguration("/**", config);
 
        return new CorsWebFilter(source);
    }
}
