1. 跨域
   協議，ip，埠如不完全相同，則需考慮跨域

2. 跨域流程
   

3. 解決跨域
   方式一：使用nginx 部署為同一域
   
   方式二：在Gateway模組中配置請求允許跨域

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(){
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource
 
();

        CorsConfiguration corsConfiguration = new CorsConfiguration();

        //1、配置跨域
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.setAllowCredentials
 
(true);
       source.registerCorsConfiguration("/**",corsConfiguration);
        return new CorsWebFilter(source);
    }
}
