ztree 异步加载 点击展开出现post请求静态资源index.html

Question

//树的设置
  var tree = {
    zTree:'',
    pNode:'',
    setting : {
      showLine : true,                  //是否显示节点间的连线
      check: {
        enable: true,
        autoCheckTrigger: true
      },
      async:{
        enable: true, //采用异步加载
        dataFilter: ajaxFilter
      },
      root:{
        isRoot:true,
        nodes:[]
      },
      data: {
        key: {
          name: "name"
        },
        simpleData: {
          enable: true,
          idKey: "id",
          pidKey: "parentId",
        }
      },
      callback: {
        beforeClick: zTreeBeforeClick,
        onExpand: zTreeOnExpand,
        onCheck: onCheck
      }
    }
  };
  function zTreeOnExpand(e, treeId, treeNode) {
    tree.zTree = $.fn.zTree.getZTreeObj("tree");
    tree.zTree.expandNode(treeNode.data);
    tree.pNode = treeNode;
    var tTreeId = JSON.parse(sessionStorage.getItem('treeId'));

      treeNode.zAsync=false;
    }
  }  

  //点击异步加载获取
  function loadNodeByPNode(treeNode) {
    var parameter= {

      treeId: treeNode.id
    };
    console.log(parameter);
    sessionStorage.setItem('treeId', JSON.stringify(treeId));
    //获取parentId = id的数据，也就是子节点的id等于父节点的id，说明此父节点加载了子节点
    if(!tree.zTree.getNodeByParam("parentId",treeNode.id)){
      BackupService.getDataSource(parameter).then(function(result){
        /**
         * 把查询出来的字节点追加到父节点上
         */
        console.log(result);
        if(result.data.data.children && result.data.data.children.length>0) {
          // tree.zTree.addNodes(tree.pNode,result.data.data.children,true);
          for(var i=0,childLen=result.data.data.children.length;i<childLen;i++) {
            result.data.data.children[i].isParent = true;
          }
          if(treeNode.children.length>0) {
            return ;
          } else {
            tree.zTree.addNodes(treeNode,result.data.data.children,true);
          }
        } else {
          return;
        };

      }, function(msg){
        console.log(msg);
      });
    }
  }

页面中没有发静态页面的静态页面的post请求，求原因？
在本地调试没有问题，在线上会出现405错误，是因为post请求静态资源，导致的405错误。
