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?
