mongodb如何获取正确的uri

标签: mongodb

我继承了mongodb系统的node.js。

原始开发者使用自己的帐户使用了mlab数据库,要求我复制到其他数据库。

当我尝试创建mlab用户时,我被重定向到cloud.mongodb.com(显然是在购买mlab)

我正在努力创建数据库并通过robo 3tCompass连接到数据库,现在我可以连接和查询数据库。

我使用Compass导出/导入集合来复制数据库(无法以任何其他方式复制)

现在我将应用程序中的数据库uri设置为新的数据库,但是当我找到findOne时它会挂起

这是旧的uri:

mongodb://dekel:password@ds115094.mlab.com:15094/somebuddy

因此,我假定连接字符串应为:

mongodb://root:password@cluster0-shard-00-00-jjbdh.mongodb.net:27017/somebuddy

我知道

UnhandledPromiseRejectionWarning: MongoNetworkError: connection 0 to cluster0-shard-00-00-jjbdh.mongodb.net:27017 closed

当我与robo 3t连接时,必须以其他方式将数据库设置为adminNetwork is unreachable.

因此,我尝试了以下

mongodb://root:password@cluster0-shard-00-00-jjbdh.mongodb.net:27017/admin

我得到:

MongoNetworkError: connection 0 to cluster0-shard-00-00-jjbdh.mongodb.net:27017 closed

Mongodb网站说连接字符串应为

mongodb+srv://root:<password>@cluster0-shard-00-00-jjbdh.mongodb.net/test?retryWrites=true

这很奇怪,因为cluster0-shard-00-00-jjbdh.mongodb.netrobo 3tCompass上不起作用,所以我想这只是一个例子。

我厌倦了以下

mongodb+srv://root:password@cluster0-shard-00-00-jjbdh.mongodb.net:27017/somebuddy

我得到:

Error: querySrv ENOTFOUND _mongodb._tcp.cluster0-shard-00-00-jjbdh.mongodb.net

我尝试了以下不同的用户

当我尝试使用mongodb网站上的聊天时,我得到: The team will get back to you on this. MongoDB Cloud Chat will be back tomorrow.

这是我尝试连接外壳时得到的信息(请参见https://www.youtube.com/watch?v=Ej05tq1220A):

答案 0 :(得分:0)

正确的uri是

mongodb+srv://root:password@cluster0-jjbdh.mongodb.net/somebuddy?retryWrites=true

实际上几乎是地图集建议的uri:

mongodb+srv://root:<password>@cluster0-jjbdh.mongodb.net/test?retryWrites=true
