Ravi Kumar's questions

我是PowerShell的新手。当我尝试执行以下代码时，出现错误：

“在语句块或类型定义中缺少结束 '}'。”

下面是代码，我不确定我在哪里失踪。

$path = "C:\Users\Dr.Salya\Downloads"
$filename = "rateonlyl-455.zip"

$url = "https://vertexinc.custhelp.com/app/utils/login_form"
$url2 = "https://download-ie.flexnetoperations.com/512175/1386/77/17129077/rateonlyl-455.zip?ftpRequestID=2321180473&server=download-ie.flexnetoperations.com&dtm=DTM20200820125043ODA0MDU5NDEz&authparam=1597953043_bf5ca04b9a74eeb53a272c20ea148517&ext=.zip/"

$ie = New-Object -com InternetExplorer.Application

$ie.visible = $true
$ie.silent = $false

$ie.navigate("$url")

while($ie.ReadyState -ne 4){start-sleep -m 100}
if ($ie.document.url -Match "invalidcert"){
$sslbypass=$ie.Document.getElementsByTagName("a") | where-object {$_.id -eq "overridelink"}
    $sslbypass.click()
    start-sleep -s 5
    }
 

$ie.Document.IHTMLDocument3_getElementById("username").click()
$ie.Document.IHTMLDocument3_getElementById("username").value ='********'
$ie.Document.IHTMLDocument3_getElementById("password").click()
$ie.Document.IHTMLDocument3_getElementById("password").value ='1234'
$ie.Document.IHTMLDocument3_getElementById("").click()

start-sleep 5

$ie.navigate($url2)

start-sleep 10

$ie.Document.body.outerHTML | Out-File -FilePath $path/$filename
