我正在尝试弄清楚如何用正则表达式验证mongoose URI。我现在的正则表达式是:

^(mongodb:\/{2})(\w*?):{0,1}(\w*?)@{0,1}(\w+?):(\d+)\/(\w+?)

我需要能够检测是否输入了用户名和密码,即

mongodb:username:password@localhost:27107/mydatabasename

所以我需要这些案例无效:

mongodb://username:localhost:27107/adfaeadf
mongodb://username:@localhost:27107/adfaeadf
mongodb://:password@localhost:27107/adfaeadf

但这些情况是否成立:

mongodb://:@localhost:27107/mydatabasename
mongodb://@localhost:27107/mydatabasename
mongodb://localhost:27107/mydatabasename
mongodb:username:password@localhost:27107/mydatabasename

任何帮助都将不胜感激

^(mongodb:(?:\/{2})?)((\w+?):(\w+?)@|:?@?)(\w+?):(\d+)\/(\w+?)$

对于你的最后一个链接,在“mongodb:“后面应该有“//”吗?但是正则表达式会匹配它。

如果要支持传递参数:

/^mongodb:\/\/(?:(?:(\w+)?:(\w+)?@)|:?@?)((?:[\w.-])+)(?::(\d+))?(?:\/([\w-]+))?(?:\?([\w-]+=[\w-]+(?:&[\w-]+=[\w-]+)*)?)?$/

这将不匹配格式为server-a1.host.com的服务器(例如除localhosts之外)或副本集,请尝试:
^(mongodb:(?:\/{2})?)((\w+?):(\w+?)@|:?@?)(\S+?):(\d+)\/(\S+?)(\?replicaSet=(\S+?))?$

如果你想在主机上支持多个分片并传递参数:

/^mongodb:\/\/(?:(?:(\w+)?:(\w+)?@)|:?@?)(((?:[\w.-])+)(?::(\d+)),((?:[\w.-])+)(?::(\d+)),((?:[\w.-])+)(?::(\d+)))?(?:\/([\w-]+))?(?:\?([\w-]+=[\w-]+(?:&[\w-]+=[\w-]+)*)?)?$/g

我的具有命名分组的版本:

/mongodb:\/\/(?:(?<login>[^\:\/\?\#\[\]\@]+)(?::(?<password>[^\:\/\?\#\[\]\@]+))?@)?(?<host>[\w\.\-]+(?::\d+)?(?:,[\w\.\-]+(?::\d+)?)*)(?:\/(?<dbname>[\w\.\-]+))?(?:\?(?<query>[\w\.\-]+=[\w\.\-]+(?:&[\w\.\-]+=[\w.\-]+)*))?/gm

这一个为我的情况工作。为mongodbMap集uri

mongodb?(\+srv):\/\/(?:(?<login>[^\:\/\?\#\[\]\@]+)(?::(?<password>[^\:\/\?\#\[\]\@]+))?@)?(?<host>[\w\.\-]+(?::\d+)?(?:,[\w\.\-]+(?::\d+)?)*)(?:\/(?<dbname>[\w\.\-]+))?(?:\?(?<query>[\w\.\-]+=[\w\.\-]+(?:&[\w\.\-]+=[\w.\-]+)*))?
