mongodb连接localhost数据库 问题

Question

本地已经可以连接到数据库；

import * as mongoose from 'mongoose';

/**
 * 连接
 */
mongoose.connect(`mongodb://127.0.0.1:27017`);

/**
 * 连接成功
 */
mongoose.connection.on('connected', function () {
    console.log('数据库连接成功');
});

/**
 * 连接异常
 */
mongoose.connection.on('error',function (err) {
    console.log('数据库连接出现错误，错误为：'+ err);
});

/**
 * 连接断开
 */
mongoose.connection.on('disconnected', function () {
    console.log('数据库连接断开');
});

module.exports = mongoose;

通过上面的代码连接却提示：

Answer 1

The connection string of connect in your code is wrong. It should be:

mongoose.connect('mongodb://localhost/test');

means connecting to the test database; if the port number is default, it can be omitted.

Cracked Wall recommends reading the documentation on the mongoose website. Some blog posts about mongoose contain errors.

For reference.

Love MongoDB! Have fun!
