你应该使用 `localhost` IP 地址来连接 MongoDB。
我不知道为什么，但当我尝试使用这个 URL 时它不起作用：```"mongodb://localhost:27017"```
请使用这个：
```use const url = "mongodb://127.0.0.1:27017";```

You should use `localhost` ip address for connecting to mongodb.
I don't know why but it was not working when i try to do with this url ```"mongodb://localhost:27017"```
Go with this one
```use const url = "mongodb://127.0.0.1:27017";```
