尝试一下，

 const MongoClient = require("mongodb").MongoClient;
 const uri ="mongodb+srv://user:userpassword@meanapp-srlw9.mongodb.net/test?retryWrites=true";
 const client = new MongoClient(uri, { useNewUrlParser: true });
 client.connect(err => {
 const collection = client.db("test").collection("devices");
 // perform actions on the collection object
   console.log("connencted");
 client.close();
});

现在，将您的群集设置更改为可以从任何地方连接
