在nodejs脚本中列出mongo数据库中的所有集合 [英] Listing all collections in a mongo database within a nodejs script

问题描述

我在shell中找到了一些列出列表的答案，但是我发现所有在nodejs脚本中列出列表的答案似乎都已被弃用，像collectionNames和moongose.connection.db return这样的答案没有方法.

I have found a few answers for listing collections in the shell but all the answers I have found for listing collections in a nodejs script seem to have been deprecated, answers like collectionNames and moongose.connection.db return has no method.

推荐答案

在用于node.js的MongoDB驱动程序的2.0版本中，您可以使用 toArray 光标以检索信息.

In the 2.0 version of the MongoDB driver for node.js you can use listCollections to get a cursor that contains the information of all collections. You can then call toArray on the cursor to retrieve the info.

db.listCollections().toArray(function(err, collInfos) {
    // collInfos is an array of collection info objects that look like:
    // { name: 'test', options: {} }
});
