使用 uriUnescapeDataString() 解碼 URL

用 [uri]::EscapeDataString() 編碼

首先，我們將在上面的例子中解碼用 [uri]::EscapeDataString() 編碼的 URL 和查詢字串：

https://example.vertigion.com/foos ？foo2 =複數％3B％2F％3F％3A％40％26％3D％2B％24％2C％20bar’％22＆複合％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"
}

這會讓你回到 [hashtable]$url_parts; 這等於（ 注： 該空間在複雜的部分是空格 ）：

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

用 [System.Web.HttpUtility]::UrlEncode() 編碼

現在，我們將在上面的例子中解碼用 [System.Web.HttpUtility]::UrlEncode() 編碼的 URL 和查詢字串：

https://example.vertigion.com/foos ？foo2 =複合％3b％2f％3f％3a％40％26％3d％2b％24％2c + bar％27％22＆複合％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"
}

這會讓你回到 [hashtable]$url_parts，它等於（ 注意： 複雜部分中的空格是第一部分中的加號 （+）和第二部分中的空格 ）：

PS > $url_parts

Name                           Value

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
----                           -----

complex;/?:@&=+$, foo'"        bar2
foo1                           bar1
