1. 组织树的简单递归算法实现

data.forEach(item=>{
  recursiveTraverse(item);
});

const recursiveTraverse = function (node) {
  if (!node || node['children'].length === 0) {
      node['children'] = null;
      return;
  }
  node['children'].forEach(function(item) {
      recursiveTraverse(item);
  });
};

1. geoserver中对于restful api使用时遇到401和403问题的解决办法：（1）遇到401时，需要在请求的headers中携带'Authorization': 'Basic YWRtaW46Z2Vvc2VydmVy'来进行解决；（2）遇到403时，说明在web.xml中，跨域信息没有完全打开，此时需要打开跨域请求，即:

   <filter>
        <filter-name>cross-origin</filter-name>
        <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
		
       <init-param>
           <param-name>chainPreflight</param-name>
           <param-value>false</param-value>
       </init-param>
       <init-param>
           <param-name>allowedOrigins</param-name>
           <param-value>*</param-value>
       </init-param>
       <init-param>
           <param-name>allowedMethods</param-name>
           <param-value>GET,POST,PUT,DELETE,HEAD,OPTIONS</param-value>
       </init-param>
       <init-param>
           <param-name>allowedHeaders</param-name>
           <param-value>*</param-value>
       </init-param>
    </filter>

    <filter-mapping>
      <filter-name>Set Character Encoding</filter-name>
      <url-pattern>/*</url-pattern>
    </filter-mapping>
   
    <filter-mapping>
        <filter-name>cross-origin</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
