Question

是否有已知的JavaScript正则表达式来匹配整个URL连接字符串？

protocol://user:password@hostname:12345/segment1/segment2?p1=val1&p2=val2

我正在寻找一个能够帮助我将这样的连接字符串转换为对象的正则表达式：

{
    protocol: 'protocol',
    user: 'user',
    password: 'password',
    host: 'hostname:12345',
    hostname: 'hostname',
    port: 12345,
    segments: ['segment1', 'segment2'],
    params: {
        p1: 'val1',
        p2: 'val2'
    }
}

此外，我希望连接字符串的每个部分都是可选的，因此缺少的参数可以通过环境中的值填充。

的示例：

protocol://
server:12345
:12345 - 仅适用于端口
user:password@
user@
:password@
/segment1
?p1=val1
等......

当涉及有效符号时，标准RFC 3986规则应适用于所有部分。

我正在寻找可以在Node.js和所有浏览器中使用的东西。

我在connection-string内逐个单独解析，但问题是 - 它不允许验证，即判断整个事情是否有效。
