Question

我将我的应用程序设置为使用 mongoose 连接到 mongodb 数据库，并认为我做得对；但是，当我运行该应用程序时，我收到以下错误消息。

//database
mongoose.connect('mongodb://http://localhost:27017/userDB', {useNewUrlParser: true, useUnifiedTopology: true });


//ERROR

const serverSelectionError = new ServerSelectionError();
                               ^

MongooseServerSelectionError: getaddrinfo ENOTFOUND http

        arbiters: [],
        tags: []
      }
    },
    stale: false,
    compatible: true,
    compatibilityError: null,
    logicalSessionTimeoutMinutes: null,
    heartbeatFrequencyMS: 10000,
    localThresholdMS: 15,

  }
}

你能指出我如何解决这个问题的正确方向吗？该应用程序在崩溃前运行了大约 1 分钟，所以我知道服务器设置正确。提前致谢。

删除 http 部分。根据官方 docs 的说法是没有必要的：

mongoose.connect('mongodb://localhost:27017/userDB', {useNewUrlParser: true, useUnifiedTopology: true });

*如果在您的机器上连接失败，请尝试使用 127.0.0.1 而不是 localhost（取自文档）

无法连接到 Mongodb 数据库
