Spring boot zuul 网关设置跨域问题大坑

baipeng 技术 , 评论

前后分离项目，在使用zuul 作微服务的网关的时候。需要设置跨域问题。
除了设置CorsFilter 还需要额外忽略重复头文件的配置。

	zuul.ignored-headers: Access-Control-Allow-Credentials, Access-Control-Allow-Origin

具体步骤：

  @Bean
	@Order
	public CorsFilter corsFilter() {
		final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
		final CorsConfiguration config = new CorsConfiguration();
		//允许跨域
		config.setAllowCredentials(true);
		config.addAllowedOrigin("*");
		config.addAllowedHeader("*");
		config.addAllowedMethod("OPTIONS");
		config.addAllowedMethod("HEAD");
		config.addAllowedMethod("GET");
		config.addAllowedMethod("PUT");
		config.addAllowedMethod("POST");
		config.addAllowedMethod("DELETE");
		config.addAllowedMethod("PATCH");
		source.registerCorsConfiguration("/**", config);
		return new CorsFilter(source);
	}
