gateway 跨域问题解决方案

1.写个配置类CorsConfig (如果不行，可以不写此类，和springcloud的版本有关)

代码语言：javascript复制

package net.youqu.micro.service.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;
import org.springframework.web.util.pattern.PathPatternParser;
import www.fhadmin.org

/**
 * description:配置类
 */
@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);
    }
}

2. 配置 application.properties 方式

代码语言：javascript复制

#--------gateway配置--------
#跨域配置
spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedOrigins=*
spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedHeaders=*
spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedMethods=*
spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowCredentials=true

yaml 方式

代码语言：javascript复制

spring:
  cloud:
    gateway:
      globalcors:
        corsConfigurations:
          '[/**]':
            allowCredentials: true
            allowedHeaders: '*'
            allowedMethods: '*'
            allowedOrigins: '*'
