PowerShell URL Encode/Decode Decode URL with `[System.Web.HttpUtility]::UrlDecode()`
Example
Encoded with [uri]::EscapeDataString()
First, we'll decode the URL and Query String encoded with [uri]::EscapeDataString() in the above example:
https://example.vertigion.com/foos? foo2=complex%3B%2F%3F%3A%40%26%3D%2B%24%2C%20bar'%22& complex%3B%2F%3F%3A%40%26%3D%2B%24%2C%20foo'%22=bar2&foo1=bar1
$url = 'https://example.vertigion.com/foos?foo2=complex%3B%2F%3F%3A%40%26%3D%2B%24%2C%20bar''%22&complex%3B%2F%3F%3A%40%26%3D%2B%24%2C%20foo''%22=bar2&foo1=bar1'
$url_parts_regex = '^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?' # See Remarks
if ($url -match $url_parts_regex) {
$url_parts = @{
'Scheme' = $Matches[2];
'Server' = $Matches[4];
'Path' = $Matches[5];
'QueryString' = $Matches[7];
'QueryStringParts' = @{}
}
foreach ($qs in $query_string.Split('&')) {
$qs_key, $qs_value = $qs.Split('=')
$url_parts.QueryStringParts.Add(
[System.Web.HttpUtility]::UrlDecode($qs_key),
[System.Web.HttpUtility]::UrlDecode($qs_value)
) | Out-Null
}
} else {
Throw [System.Management.Automation.ParameterBindingException] "Invalid URL Supplied"
}
This gives you back [hashtable]$url_parts; which equals (Note: the spaces in the complex parts are spaces):
PS > $url_parts

QueryString foo2=complex%3B%2F%3F%3A%40%26%3D%2B%24%2C%20bar'%22&complex%3B%2F%3F%3A%40%26%3D%2B%24%2C%20foo'%22=bar2&foo1=bar1

Encoded with [System.Web.HttpUtility]::UrlEncode()
Now, we'll decode the URL and Query String encoded with [System.Web.HttpUtility]::UrlEncode() in the above example:
https://example.vertigion.com/foos? foo2=complex%3b%2f%3f%3a%40%26%3d%2b%24%2c+bar%27%22& complex%3b%2f%3f%3a%40%26%3d%2b%24%2c+foo%27%22=bar2&foo1=bar1
$url = 'https://example.vertigion.com/foos?foo2=complex%3b%2f%3f%3a%40%26%3d%2b%24%2c+bar%27%22&complex%3b%2f%3f%3a%40%26%3d%2b%24%2c+foo%27%22=bar2&foo1=bar1'
$url_parts_regex = '^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?' # See Remarks
if ($url -match $url_parts_regex) {
$url_parts = @{
'Scheme' = $Matches[2];
'Server' = $Matches[4];
'Path' = $Matches[5];
'QueryString' = $Matches[7];
'QueryStringParts' = @{}
}
foreach ($qs in $query_string.Split('&')) {
$qs_key, $qs_value = $qs.Split('=')
$url_parts.QueryStringParts.Add(
[System.Web.HttpUtility]::UrlDecode($qs_key),
[System.Web.HttpUtility]::UrlDecode($qs_value)
) | Out-Null
}
} else {
Throw [System.Management.Automation.ParameterBindingException] "Invalid URL Supplied"
}
This gives you back [hashtable]$url_parts; which equals (Note: the spaces in the complex parts are spaces):
