我有一个网址，我需要为该网址输入一个端口号。网址不是有效网址。这里有几个展示案例：
https://example.com_users/param/param/param - https://example.com_users:8080/param/param/param
http://example.co_setting/param/param/param - http://example.co_settings:1000/param/param/param
http://example.co_setting- http://example.co_settings:1000
const addPort = (url,port) =>{
combined = ???????? // how to combian them
return combined
}您可以使用正则表达式：
const addPort = (url, port) =>
url.replace(/^(https?:\/\/)?([^/]*)(\/.*)?$/, '$1' + '$2:' + port + '$3');
console.log(addPort('http://www.example.com/full/url/with/param', '8080'))本文收集自互联网，转载请注明来源。
