Zuul路由不能正确映射到ribbon listOfServers (没有尤里卡)

Question

我正在尝试为我的http://host2:port2/rest-example/app1路由配置ribbon，所以当我转到zuul时，它应该会将我路由到zuul。当我使用"url“属性定义路由时，它可以正常工作，而不使用ribbon：

zuul:
  routes:
      restful-service:
          path: /restful-service/**
          url: http://host2:port2/rest-example

但是当我尝试使用ribbon时，它看起来像这样：

zuul:
  routes:
    restful-service:
      path: /restful-service/**
      serviceId: restful-service

ribbon:
  eureka:
    enabled: false

restful-service:
  ribbon:
    listOfServers: host2:port2/rest-example

它只允许我路由到http://host2:port2/rest-example，而不是直接路由到所选的服务http://host2:port2/rest-example/app1 (它返回404状态码)。

将您的配置属性更改为以下内容-

    zuul:
        routes:
              restful-service:
                       serviceId:restful-service
                       stripPrefix:false

   ribbon:
        eureka:
             enabled:false

   restful-service:
        ribbon:
            listOfServers: host2:port2

然后，您需要编写一个zuul预过滤器来更改requestURI

      public class CustomPreFilter extends ZuulFilter {

      public Object run() {

       RequestContext context=RequestContext.getCurrentContext();
       String oldrequestURI=(String) context.get("requestURI");
       String newrequestURI=oldrequestURI.replace("restful-service", "rest-example");
       context.put("requestURI",newrequestURI);
       return null;
     }

      public boolean shouldFilter() {

       HttpServletRequest httpServletRequest=RequestContext.getCurrentContext().getRequest();
    if(httpServletRequest.getRequestURI().contains("/restful-service"))
        return true;
    else
        return false;
   }

       @Override
       public int filterOrder() {
       return PreDecorationFilter.FILTER_ORDER+1;
   }

      @Override
      public String filterType() {
      return "pre";
   }

 }

现在提出一个请求，这将适用于您想要做的事情。

listOfServers属性仅支持主机和端口，不支持路径。
