How to solve the cross-domain problem of springcloud alibaba gateway, I believe that many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

1. Write a configuration class CorsConfig (if not, you don't have to write this class, depending on the version of springcloud)

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;/** * description: * java project www.fhadmin.org * / @ Configurationpublic class CorsConfig {@ Beanpublic 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);}}

two。 Configure application.properties mode

#-gateway configuration-# Cross-domain configuration 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 mode

Spring: cloud:gateway: globalcors:corsConfigurations:'[/ *]': allowCredentials: trueallowedHeaders:'* 'allowedMethods:' * 'allowedOrigins:' * 'after reading the above, have you mastered how to solve the cross-domain problem of springcloud alibaba gateway?
