Question

我正在使用＆＃34; mongodb-backup＆＃34;用于获取数据库备份的插件。

数据库连接网址链接：

var _dbConnectionURL = 'mongodb://uname:password@LocalIpAddress:port/databasename?authdb=admin';
mongoose.connect(_dbConnectionURL);

此代码用于连接nodejs和mongodb。它运作良好。

现在我尝试从nodejs

进行备份

var backup = require('mongodb-backup');
backup({
    uri: _dbConnectionURL,
    root: './Media/MongoDB_BK',
    tar: 'sample.tar',
    callback: function (err) {
        if (err) {
            console.error(err);
        } else {
            console.log('finish');
        }
    },
});

错误：

Answer 1

尝试使用authsource而不是authdb

var _dbConnectionURL = 'mongodb://uname:password@LocalIpAddress:port/databasename?authsource=admin';

或尝试在options参数

中设置authdb

backup({
    uri: _dbConnectionURL,
    root: './Media/MongoDB_BK',
    tar: 'sample.tar',
    options: {
       authSource: 'admin'    
    }
});
