Question

我试图找出如何使用正则表达式验证mongoose URI。我现在的正则表达是：

^(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

但这些情况有效：

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

任何帮助将不胜感激

Answer 1

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

对于你的上一个链接，“mongodb：”之后应该有“//”吗？正则表达式将以任何一种方式匹配。

Answer 2

如果您想支持传递参数：

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

Answer 3

用于 mongodb+srv 用于 mongodb atlas url。

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

Answer 4

这与server-a1.host.com格式的服务器（例如，本地主机以外的服务器）或副本集不匹配，请尝试：

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

Answer 5

如果要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
