本篇内容主要讲解"spring cloud zuul如何解决跨域访问"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"spring cloud zuul如何解决跨域访问"吧!

spring zuul是不支持跨域的,需要对其进行配置

1.配置 application.yml

zuul:  sensitive-headers: Access-Control-Allow-Origin  ignored-headers: Access-Control-Allow-Origin,Vary,X-Frame-Options,token

猜测关键点在第二行,忽略Access-Control-Allow-Origin这种方式;

2.配置filter

@Configurationpublic class GatewayCrosConfig {    @Bean    public CorsFilter corsFilter() {        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();        final CorsConfiguration corsConfiguration = new CorsConfiguration();//        corsConfiguration.setAllowCredentials(true);        corsConfiguration.addAllowedHeader("*");        corsConfiguration.addAllowedOrigin("*");        corsConfiguration.addAllowedMethod("*");        source.registerCorsConfiguration("/**", corsConfiguration);        return new CorsFilter(source);    }}

3. zuul 与cloud内部服务的跨域问题

zuul内部转发是不存在跨域问题的

4. spring mvc 配置跨域

@Configurationpublic class WebConfig extends WebMvcConfigurationSupport {@Override    public void addCorsMappings(CorsRegistry registry) {        registry.addMapping("/**")                .allowedHeaders("Content-Type","X-Requested-With","accept,Origin","Access-Control-Request-Method","Access-Control-Request-Headers","token")                .allowedMethods("*")                .allowedOrigins("*")                .allowCredentials(true);    }}

通过设置cors配置来实现
