我将 Zuul 作为 API 网关，因此它具有所有服务的所有映射。我们在所有不同的服务中都有用于异常处理的自定义错误消息。
Content-Type:application/j
我遇到的问题是，如果我有上面的 Content-Type 假设是错误的，它会命中 API，我会收到我必须处理该场景的自定义消息。
Content-Type:applicatio
但是当我有上面的内容类型时，即没有“/”。Zuul 实际上会拦截它并抛出它自己的错误，如下所示。我已经添加了它抛出的邮递员的错误。
我怎样才能让 Zuul 忽略这一点，然后点击服务，这样我就可以得到我的自定义错误消息。
我在 Zuul 中也有这个 CorsFilter 来处理跨域问题：-
@Bean
public CorsFilter corsFilter() {
final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
final CorsConfiguration config = new CorsConfiguration();
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);
}
