问题描述

SpringCloudGateWay中跨域配置不起作用

使用filter

@Component
public class CORSFilter implements Filter{

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse res = (HttpServletResponse) response;
        res.addHeader("Access-Control-Allow-Credentials", "true");
        res.addHeader("Access-Control-Allow-Origin", "*");
        res.addHeader("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT");
        res.addHeader("Access-Control-Allow-Headers", "Content-Type,X-CAF-Authorization-Token,sessionToken,X-TOKEN");
        if (((HttpServletRequest) request).getMethod().equals(HttpMethod.OPTIONS)) {
            response.getWriter().println("ok");
            return;
        }
        chain.doFilter(request, response);
    }

}

使用注解

自定义filter

@Configuration
public class CORSFilter{
    @Bean
    public CorsFilter corsFilter(){
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.setAllowCredentials(true);
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addExposedHeader("*");
        UrlBasedCorsConfigurationSource corsConfigurationSource = new UrlBasedCorsConfigurationSource();
        corsConfigurationSource.registerCorsConfiguration("/**",corsConfiguration);
        //3. 返回新的CorsFilter
        return new CorsFilter(corsConfigurationSource);
    }
}
