问尤龙の时光
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 CorsConfig {
@Bean
public CorsWebFilter corsWebFilter(){
CorsConfiguration configuration = new CorsConfiguration();
configuration.addAllowedHeader("*");
configuration.addAllowedMethod("*");
configuration.addAllowedOriginPattern("*");
// configuration.addAllowedOrigin("*"); setAllowCredentials为true，就使用addAllowedOriginPattern替代这个配置
configuration.setAllowCredentials(true);
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**",configuration);
return new CorsWebFilter(source);
}
}
代码注释掉的哪一行有个坑，如果使用注释掉的代码来进行配置就会报错，spring cloud gateway配置中如果setAllowCredentials为true，就得用addAllowerOriginPattern代替addAlloweOrigin做配置，原文档描述如下
