从mongo结果中删除_id [英] remove _id from mongo result

问题描述

我对mongo和nodejs很陌生 作为查询的结果，我有一个json，我只想将结果作为http请求返回，如下所示:

I'm pretty new with mongo and nodejs I've a json as result of my query and I simply want to return the result as an http request, as following:

app.get('/itesms', function(req, res) {
  items.find().toArray(function (err, array) {
    res.send(array);
  })
});

它有效，唯一的问题是我想(递归地)从结果中隐藏_id字段. 有任何建议以优雅的方式做到这一点吗?

It works, only problem is that I want to hide the _id fields (recursively) from the result. Any suggestion to do that in an elegant way?

推荐答案

尝试以下解决方案:

app.get('/itesms', function(req, res) {
  items.find({}, { _id: 0 }).toArray(function (err, array) {
    res.send(array);
  })
});
