Question

当我启动环回服务器时，我收到此错误。代码中的一切看起来都很完美。我传递主机名，数据库名称，用户名，密码和端口。

 /var/www/investickations_web/node_modules/loopback-connector-mongodb/node_modules/mongodb/lib/url_parser.js:24
        throw new Error('no hostname or hostnames provided in connection string');
    ^

Answer 1

发现Loopback-MongoDB-Connector的url_parser.js中存在错误。如果密码字符串中包含@，则无法解析并构建MongoDB连接字符串。

请自行准备好连接字符串并将其作为＆＃39; url＆＃39;数据源JSON中的字段或更改您的MongoDB密码，因此它不包含@字符。

Answer 2

以下是连接到mongo的示例连接字符串。正如achintverma所说，不要在密码中使用@。

"mongoDS": {
    "url": "mongodb://paanoop:*password*@ds035683.mongolab.com:1234/fsbs",
    "database": "",
    "password": "*password*",
    "name": "your data source",
    "user": "username",
    "connector": "mongodb"
}

环回mongodb连接器连接字符串
