JS regular determines whether the port path of the domain name or IP is correct

adopt js Regular to judge ip Port path http://127.0.0.1:3000/list perhaps https://www.baidu.com:8080/list Whether it is right

const reg = new RegExp(/^http(s)?:\/\/((www\.)?[a-zA-Z0-9]{0,62}(\.[a-zA-Z0-9]{0,62})|(1\d{2}|2[0-4]\d|25[0-5]|[1-9]\d|[0-9])\.((1\d{2}|2[0-4]\d|25[0-5]|[1-9]\d|\d)\.){2}(1\d{2}|2[0-4]\d|25[0-5]|[1-9]\d|\d))\:([0-9]|[1-9]\d{1,3}|[1-5]\d{4}|6[0-5]{2}[0-3][0-5])\/+[a-zA-Z0-9]/)

reg.test(“https://www.aaaa.com:2000/105”) // true
reg.test(“https://127.0.0.1:2000/105”) // true
reg.test(“https://127.0.0.1:2000/System/list”) // true
reg.test(“https://127.0.0.1:2000/dict/list”) // true
reg.test(“http://127.0.0.1:2000/dict/list”) // true

Verified integrity url, The following method can be used to extract ip、 port . route

//  obtain ip Address 、 port 、 Lu Jin 
getUrlComponent (url) {
    
  let res = {
    }
  if (url.indexOf('//') !== -1 || url.indexOf(':') !== -1 || url.indexOf('.') !== -1) {
    
    //  Don't intercept http
    let str = url.indexOf('//') !== -1 ? url.substr(url.indexOf('//') + 2) : url
    res.ip = str.indexOf(':') !== -1 ? str.substr(0, str.indexOf(':')) : str.indexOf('/') !== -1 ? str.substr(0, str.indexOf('/')) : str
    res.port = str.indexOf('/') !== -1 ? str.slice(str.indexOf(':') + 1, str.indexOf('/')) : str.substr(str.indexOf(':') + 1)
    res.path = res.port !== '' && str.indexOf(res.port) !== -1 ? str.substr(str.indexOf(res.port) + res.port.length) : str.indexOf('/') !== -1 ? str.substr(str.indexOf('/')) : ''
  }
  return res
}
