Question

我有一个像这样的HTML表单：

<input name="member[email]" id="memberemail" style="width: 220px;" type="text" value="">
<input name="member[password]" id="memberpassword" style="width: 220px;" type="password" value="" autocomplete="off">
<input class="continue" type="submit" value="Log In">

我有一个PowerShell脚本可以验证和浏览页面：这很好用。

$username='xxx@mail.com' 
$password='<password>'




$ie = New-Object -ComObject 'internetExplorer.Application'
$ie.Visible= $true
$ie.Navigate("https://www.ksl.com/public/member/signin?login_forward=%2F")


while ($ie.Busy -eq $true){Start-Sleep -seconds 1;}   

$usernamefield = $ie.Document.getElementByID('memberemail')
$usernamefield.value = $username

$passwordfield = $ie.Document.getElementByID('memberpassword')
$passwordfield.value = $password

$Link=$ie.Document.getElementsByTagName("input") | where-object {$_.className -eq "continue"}



#<INPUT tabIndex=3 id=Logon onclick=this.disabled=true;this.form.submit(); type=submit value="Sign In">
#<input name="ctl00$pageContentPlaceHolder$btnGo" id="ctl00_pageContentPlaceHolder_btnGo" style="width: 200px;" type="submit" value="Sign In">


$Link.click()

然而，当我尝试在ASP.net页面上使用它时，这样：

<input name="ctl00$pageContentPlaceHolder$txtUserID" id="ctl00_pageContentPlaceHolder_txtUserID" style="width: 200px;" type="text" maxlength="30" autocomplete="off">
<input name="ctl00$pageContentPlaceHolder$txtPassword" id="ctl00_pageContentPlaceHolder_txtPassword" style="width: 200px;" type="password" maxlength="256" autocomplete="off">
<input name="ctl00$pageContentPlaceHolder$btnGo" id="ctl00_pageContentPlaceHolder_btnGo" style="width: 200px;" type="submit" value="Sign In">

此修改后的脚本未填写用户名和密码字段

$username='use000' 
$password='<password>'


$ie = New-Object -ComObject 'internetExplorer.Application'
$ie.Visible= $true
#ie.Navigate("https://fasttrng.usask.ca/Login.aspx?ReturnUrl=%2f")

while ($ie.Busy -eq $true){Start-Sleep -seconds 1;}   

$usernamefield = $ie.Document.getElementByName('ctl00$pageContentPlaceHolder$txtUserID')
$usernamefield.value = $username

$passwordfield = $ie.Document.getElementByName('ctl00$pageContentPlaceHolder$txtPassword')
$passwordfield.value = $password

$Link=$ie.Document.getElementsByTagName("input") | where-object {$_.id -eq "ctl00_pageContentPlaceHolder_btnGo"}




$Link.click()
