Question

我的问题是，我正在使用invoke web-request登录到一个网站。我能够成功登录该网站。我的问题是，当我转到url时，它认为我没有登录。我使用同一会话变量登录并转到特定页面。

这是显示我已登录的屏幕截图，但是我无法访问网站的一部分来上传一些文件。

$Global:organization = Read-Host "`tEnter the organization"
$username = Read-Host "`tEnter the username"
$password = Read-Host "`tEnter the password"

$form.fields["organization"] = $organization
$form.fields["Username"] = $username
$form.fields["Password"] = $password

$Global:loginResponse = Invoke-WebRequest -uri ("https://dealer.md-bmc.rpdss.com/" + $form.Action) -WebSession $login -Method post -Body $form.Fields

if ($loginResponse.ParsedHtml.title -eq "RAPID Dealer Reporting Site") {
    Write-Host "`tLog in failed, please try again! `n" -ForegroundColor Red
}

else {
$info = $loginResponse.AllElements | where {$_.tagName -contains "span"}
$account = ($info.innerhtml | Select-Object -First 3).ToUpper()
Write-Host "`tLogged in as" $account "`n" -ForegroundColor Green
$upload = $loginResponse.AllElements.InnerHtml | Where-Object {$_ -match 'url="(administration/uploadprofileselector.aspx\?.*?)"'} |ForEach-Object {$matches[1]} | Select-Object -First 1

$uid = ($upload -replace '\D').Substring(0,4)
$oid = ($upload -replace '\D').Substring(4,6)

#this is where it "forgets" that it's already logged in.

$fileUploadurl = "https://dealer.md-bmc.rpdss.com/bwident/pawnshop/administration/uploadprofileselector.aspx?l=English&uid=$uid&oid=$oid"
$fileUploadPage = Invoke-WebRequest -Uri $fileUploadurl -WebSession $login

#this should be showing me a selection menu, but it's asking me to login again.  Please see screenshot.
$fileUploadPage.ParsedHtml.body.innerText
}

在第一次调用Invoke-WebRequest时，您使用-SessionVariable参数设置了会话变量：

$Global:loginResponse = Invoke-WebRequest -uri ("https://dealer.md-bmc.rpdss.com/" + $form.Action) -SessionVariable login -Method post -Body $form.Fields

（如您所见，变量名在这里没有$前缀。您甚至可以像'login'一样引用它，以使其更加清楚，它只是变量（字符串）的名称）

在随后的对Invoke-WebRequest的调用中，您使用该会话变量和-WebSession参数：

$fileUploadPage = Invoke-WebRequest -Uri $fileUploadurl -WebSession $login

p.s。如我前面的评论中所述，您还必须修复代码中的($upload -replace '\D')，因为您现在正尝试将所有非数字字符替换为????
