我想设置一个脚本来登录到特定的 SolarWinds 显示视图并每 30 秒不断刷新页面。我检查了其他几个代码示例，我的看起来不错，但它不起作用。

我的问题：自动登录不起作用，没有在字段中输入任何内容，也没有单击登录按钮。我也不知道如何让它刷新页面而不是每次打开一个新页面。

任何帮助表示赞赏！

这是我的代码：

$Run = 1

do {

#Create the IE com object to be used for logging into SAM
$ie = new-object -com InternetExplorer.Application 
$ie.visible = $true
$ie.ToolBar = $false
#$ie.Width = 1300
#$ie.Height = 1000
$ie.FullScreen = $true
$ie.Left = 0
$ie.Top = 0
$SolarWinds = "http://SolarWindsServer/Orion/Login.aspx"
$username = "username"
$password = "password"

$ie.navigate($SolarWinds)
do {
    Sleep 1000
   }while ($ie.Busy -eq "True")

sleep 30

#Find the username field and enter username 
$ie.Document.getElementById('ctl00_BodyContent_Username').value = $username;

#Find the password field and enter password
$ie.Document.getElementById('ctl00_BodyContent_Password').value = $password;

#Find and click the submit button 
$ie.Document.getElementById('SiteLoginText').submit() 

do {
    Sleep 5
   }while ($ie.Busy -eq "True")

sleep 30
}while ($Run -eq 1)

首先，我收到了这些错误，所以看起来登录不起作用：

您不能在空值表达式上调用方法。在 C:\Users\me\Desktop\SAMTEST.ps1:25 char:28 + $ie.Document.getElementById <<<< ('ctl00_BodyContent_Username').value = $username; + CategoryInfo : InvalidOperation: (getElementById:String) [], RuntimeException + FullyQualifiedErrorId : InvokeMethodOnNull

您不能在空值表达式上调用方法。在 C:\Users\me\Desktop\SAMTEST.ps1:28 char:28 + $ie.Document.getElementById <<<< ('ctl00_BodyContent_Password').value = $password; + CategoryInfo : InvalidOperation: (getElementById:String) [], RuntimeException + FullyQualifiedErrorId : InvokeMethodOnNull

您不能在空值表达式上调用方法。在 C:\Users\me\Desktop\SAMTEST.ps1:31 char:28 + $ie.Document.getElementById <<<< ('SiteLoginText').submit() + CategoryInfo : InvalidOperation: (getElementById:String) [] , RuntimeException + FullyQualifiedErrorId : InvokeMethodOnNull

以下是页面源代码的片段：

您最好只在 URL 上提供凭据。在这里查看我的答案：Automatically authenticate into SolarWinds and view data using a URL
