无法连接 MongoDB 服务器？

Question

我尝试使用下面提到的链接连接到 MongoDB 服务器，但出现错误，我输入了正确的密码和 dbName 但无法连接。你能帮帮我吗？

const mongoose = require('mongoose');
    mongoose.connect(`mongodb+srv://test:Test@123@cluster0.cvbne.mongodb.net/example?retryWrites=true&w=majority`,{userNewUrlParser : true, useUnifiedTopology: true},
    err => {
        if(!err)
        console.log ("'mongoddb connection successed")
        else
        console.log ('Error white connecting mongodb : ' + JSON.stringify(err, undefined,2))
    })

改用这个：

mongoose.connect(`mongodb+srv://test:Test@123@cluster0.cvbne.mongodb.net/example?retryWrites=true&w=majority`), {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});
const db = mongoose.connection;
db.on("error", console.error.bind(console, "connection error:"));
db.once("open", () => console.log("---Connected to DB!---"));
