PowerShell URL Encode/Decode Decode URL with `[uri]::UnescapeDataString()`
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('=') $url_parts.QueryStringParts.Add( [uri]::UnescapeDataString($qs_key), [uri]::UnescapeDataString($qs_value) ) | Out-Null } } else { Throw [System.Management.Automation.ParameterBindingException] "Invalid URL Supplied" } This gives you back [hashtable]$url_parts; which equals (Note: the spaces in the complex parts are spaces):
PS > $url_parts Name Value ---- ----- Scheme https Path /foos Server example.vertigion.com QueryString foo2=complex%3B%2F%3F%3A%40%26%3D%2B%24%2C%20bar'%22&complex%3B%2F%3F%3A%40%26%3D%2B%24%2C%20foo'%22=bar2&foo1=bar1 QueryStringParts {foo2, complex;/?:@&=+$, foo'", foo1} PS > $url_parts.QueryStringParts Name Value ---- ----- foo2 complex;/?:@&=+$, bar'" complex;/?:@&=+$, foo'" 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('=') $url_parts.QueryStringParts.Add( [uri]::UnescapeDataString($qs_key), [uri]::UnescapeDataString($qs_value) ) | Out-Null } } else { Throw [System.Management.Automation.ParameterBindingException] "Invalid URL Supplied" } This gives you back [hashtable]$url_parts, which equals (Note: the spaces in the complex parts are plus signs (+) in the first part and spaces in the second part):
PS > $url_parts Name Value ---- ----- Scheme https Path /foos Server example.vertigion.com QueryString foo2=complex%3b%2f%3f%3a%40%26%3d%2b%24%2c+bar%27%22&complex%3b%2f%3f%3a%40%26%3d%2b%24%2c+foo%27%22=bar2&foo1=bar1 QueryStringParts {foo2, complex;/?:@&=+$, foo'", foo1} PS > $url_parts.QueryStringParts Name Value ---- ----- foo2 complex;/?:@&=+$, bar'" complex;/?:@&=+$, foo'" bar2 foo1 bar1
