我有一个像这样的示例mongo文档:
> db.chat.find().pretty()
{
"_id": ObjectId("555f1c0c7f4b820758b439b0"),
"user": "Guest1",
"friend": [{
"userfriend": "Guest2",
"noidung": [{
"method": "send",
"date": "2015-05-22T19:11:34+07:00",
"content": "allloooo"
}, {
"method": "receive",
"date": "2015-05-23T09:08:14+07:00",
"content": "yes man"
}]
}, {
"userfriend": "Guest3",
"noidung": [{
"method": "send",
"date": "2015-05-23T15:42:34+07:00",
"content": "foo 15:42"
}, {
"method": "receive",
"date": "2015-05-23T15:42:45+07:00",
"content": "bar 15:43"
}]
}]
}
在我的server.js中,我使用此代码打印所有数据:
var chathistory = db.collection('chat');
chathistory.find().toArray(function (err, docs) {
console.log(docs)
});
我在终端上输入了这个日志:
[ { _id: 555f1c0c7f4b820758b439b0,
user: 'Guest1',
friend: [ [Object], [Object] ] } ]
'朋友'字段不打印全部,仅打印[Object]
,因此如何获取完整数据。
答案 0 :(得分:3)
要打印所有数据,请使用 JSON.stringify()
方法
db.collection('chat').find().toArray(function(err, docs) {
console.log(JSON.stringify(docs));
});
