Extract first part of URL-CodePudding

I have an URL like so:

https://www.example.com/oauth/connect/token

I want to get only https://www.example.com and I have tried a bunch of ways to get this but all the ways I have tried require me to hardcode multiple /s.

Example:

$Url.Split('/')[0] "//" $url.split('/')[2]

Is there a way to do this without using the harcoding?

CodePudding user response：

You may use [System.Uri], to 'cast' the string into an System.Uri class.

$url = [System.Uri]"https://www.example.com/oauth/connect/token"

You can then use the host and scheme to get the part of the URL you want.

$result = $url.Scheme, $url.Host -join "://"

You could also remove the AbsolutePath from the entire URL.

$url = [System.Uri]"https://www.example.com/oauth/connect/token"

$result = $url.AbsoluteUri.Replace($url.AbsolutePath, "")

This is the complete list of attributes that the System.Uri instance will have:

AbsolutePath   : /oauth/connect/token
AbsoluteUri    : https://www.example.com/oauth/connect/token
LocalPath      : /oauth/connect/token
