Question

route.js

router.get('/restful', function(req, res){
  console.log("before");
  User.show_deatils(req, res, function(err, resultArray){
   if(!err) {
     req.session.resultArray=resultArray;
    }
  });
  console.log(req.session.resultArray);
  res.render('restful',{resultArray:req.session.resultArray});
});

我不知道为什么当我在上面的位置undefined进行console.log()时我得到console.log()。如果我在req.session.resultArray=resultArray之后resultArray那么我们得到结果数组。

我想在view.ejs中显示此curl -s -XGET 'localhost:9200/index_name/type/_search?pretty=true&size=10' -d '{ "query": { "bool": { "must": { "match": { "logtype": "error" } }, "must_not": { "match": { "logMessage": "*error occured*" } } } } }'。任何人都可以建议我如何解决它。我错过了什么？

在异步函数实际从数据库中获取详细信息之前，console.log运行。所以你得到了不确定。在回调中进行渲染。即，在将结果数组分配给会话之后。

就这样做

    router.get('/restful', function(req, res){
           console.log("before");
          User.show_deatils(req, res, function(err, resultArray){
           if(!err) { 

             res.render('restful',{resultArray:resultArray});
           }
          });
       });

我认为这就是你想要的。
