Powershell自动登录网站$ie.Document.getElementsByClassName

Question

我正在尝试设置一个PowerShell，它将把我登录到我儿子的学校门户网站并提交所需的表格。我每天都要做一个，我得到了一个很好的想法，那就是我可以编写它的脚本。下面是脚本和错误

$ie = New-Object -ComObject 'internetExplorer.Application'
$ie.Visible= $true # Make it visible
$username="Username"
$password="Password"
$ie.Navigate("https://parents.genesisedu.com/hasbrouckheights/parents?module=home&studentid=1000333&action=form")
While ($ie.Busy -eq $true) {Start-Sleep -Seconds 3;}
$usernamefield = $ie.document.getElementByID('j_username')
$usernamefield.value = "$username"
$passwordfield = $ie.document.getElementByID('j_password')
$passwordfield.value = "$password"
$Link = $ie.Document.getElementsByClassName(“saveButton”)[0].value="Login"
$Link.click()

---

Method invocation failed because [System.String] does not contain a method named 'click'.
At line:19 char:1
+ $Link.click()
+ ~~~~~~~~~~~~~
+ CategoryInfo          : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : MethodNotFound

---

我尝试了很多变体，但似乎无法让它达到"；登录"；按钮任何帮助都将不胜感激。。。

您当前在调用Click()之前将字符串值"Login"分配给$Link，因此出现错误。

更改此项：

$Link = $ie.Document.getElementsByClassName(“saveButton”)[0].value="Login"

至：

$Link = $ie.Document.getElementsByClassName(“saveButton”)[0]
