regex - URL中作为参数传递的特殊字符

Question

要求:需要一种方法来处理特殊字符，例如%和&。需要调整以下代码，以便按原样处理通过$Control文件传入的特殊字符。

例如:我在$control文件中有一个条目25% Dextrose(25ml)。我需要一种方法，以便$ie.Navigate应该简单地导航到https://www.xxxy.com/search/all?name=25% Dextrose(25ml)。当前，它被路由到https://www.xxxy.com/search/all?name=25%% Dextrose(25ml)(注意URL中的额外％)，因此找不到该网页。

**Few examples of special characters that need to be tackled:** 
'/' - 32care Mouth/Throat
'%' - 3d1% Gel(30g)
'&' - Accustix Glucose & Protein
'/' - Ace Revelol(25/(2.5mg)


function getStringMatch
     {
        # Loop through all 2 digit combinations in the $path directory
        foreach ($control In $controls)
        {
            $ie = New-Object -COMObject InternetExplorer.Application
            $ie.visible = $true
            $site = $ie.Navigate("https://www.xxxy.com/search/all?name=$control")
            $ie.ReadyState

            while ($ie.Busy -and $ie.ReadyState -ne 4){ sleep -Milliseconds 100 }

            $link = $null
            $link = $ie.Document.get_links() | where-object {$_.innerText -eq "$control"}
            $link.click()

            while ($ie.Busy -and $ie.ReadyState -ne 4){ sleep -Milliseconds 100 }

           $ie2 = (New-Object -COM 'Shell.Application').Windows() | ? {
           $_.Name -eq 'Windows Internet Explorer' -and $_.LocationName -match "^$control"
           }

            # NEED outerHTML of new page. CURRENTLY it is working for some.

            $ie.Document.body.outerHTML > d:\med$control.txt
        }
    }

    $controls = "Sporanox"

    getStringMatch

您要对URI进行URL编码。首先添加:

Add-Type -AssemblyName 'System.Web'

然后像这样编码URL:

$controlUri = [System.Web.HttpUtility]::UrlEncode($control)
$site = $ie.Navigate("https://www.xxxy.com/search/all?name=$controlUri")
