这篇文章主要介绍了SpringCloud Gateway跨域配置代码实例,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
Springboot版本:2.1.8.RELEASE
SpringCloud版本:Greenwich.SR2
yml配置:
spring: cloud: gateway: globalcors: cors-configurations: '[/**]': # 允许携带认证信息 # 允许跨域的源(网站域名/ip),设置*为全部 # 允许跨域请求里的head字段,设置*为全部 # 允许跨域的method, 默认为GET和OPTIONS,设置*为全部 # 跨域允许的有效期 allow-credentials: true allowed-origins: - "http://localhost:13009" - "http://localhost:13010" allowed-headers: "*" allowed-methods: - OPTIONS - GET - POST max-age: 3600 # 允许response的head信息 # 默认仅允许如下6个: # Cache-Control # Content-Language # Content-Type # Expires # Last-Modified # Pragma #exposed-headers:
配置类:org.springframework.cloud.gateway.config.GlobalCorsProperties
网上有很多人说这样配无效,但我测试下来是OK的,如果真的无效,可以手动去装配Cros配置:
package com.longge.gateway.configuration; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.autoconfigure.condition.ConditionalOnBean; import org.springframework.cloud.gateway.config.GlobalCorsProperties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.cors.reactive.CorsWebFilter; import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource; import org.springframework.web.util.pattern.PathPatternParser; /** * @author roger yang * @date 11/21/2019 */ @Configuration @ConditionalOnBean(GlobalCorsProperties.class) public class CorsAutoConfiguration { @Autowired private GlobalCorsProperties globalCorsProperties; @Bean public CorsWebFilter corsFilter() { UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(new PathPatternParser()); globalCorsProperties.getCorsConfigurations().forEach((path,corsConfiguration)->source.registerCorsConfiguration(path,corsConfiguration)); return new CorsWebFilter(source); } }
当然,我们更推荐在Nginx等中间件去做跨域的处理,业务服务就应该关注业务。
