mongodump之后，我做了mongorestore，似乎工作正常
heathers-air:db heathercohen$ mongorestore -v -host localhost:27017

但是，当我尝试访问数据时，它仍然是空的，并且在还原之前看起来是这样的：
> show dbs
admin (empty)
dump 0.078GB
local 0.078GB
tweets (empty)
twitter (empty)
它说发现了30597个物体，它们去了哪里？
他们进入了转储数据库，然后进入了集合dump.tweets和dump.langs。文件包含在文件夹中的事实dump意味着mongorestore认为它们应该还原到数据库中dump（从路径推断）。详细输出甚至明确声明要将数据放入其中dump.langs，dump.tweets尤其是。
如果您指定要还原到的数据库（使用-d）并还原特定文件，则可以将文档还原到所需的数据库。或者，您可以通过运行以下命令简单地查看转储数据库：
use dump;
db.tweets.find();
db.langs.find();
