Question

我正忙于创建Express应用并使用mongodb。

虽然我仍在学习，但在开发中，我想在docker内部使用mongodb。目前，我的进程是（在Ubuntu 18上运行）-

docker pull mongo

一旦拉开，我就用它运行

docker run -p 27017:27017 mongo

一旦运行，我可以在终端中看到mongo输出，如果我进入浏览器的端口，则会收到以下消息

It looks like you are trying to access MongoDB over HTTP on the native driver port.

然后让我的快速应用程序句柄连接到数据库，并启动服务器。

var db 
var url = 'mongod://localhost:27017/'
MongoClient.connect(url,{ useNewUrlParser: true }, (err, database) => {
if(err) return console.log(err)

    db = database.db('quotes_db')

    app.listen(3000, () => {
    console.log("listening on port 3000...");
  });
})

启动快递服务器时出现错误-

  name: 'MongoParseError',
  [Symbol(mongoErrorContextSymbol)]: {} }

我知道这与连接字符串有关，但是我发现的帖子和文章都在说我做对了。

这是源代码的链接-

无法连接到本地mongodb docker
