Hi! I am trying to write a PowerShell script to login to a forum.

$wc = new-object system.net.webclient
$wc.credentials = new-object system.net.networkcredential("username", "password"
$wc.DownloadFile(" http://www.forex-tsd.com/", "d:\work\index.html"

This does not work.

I found:

http://scriptolog.blogspot.com/2007/01/automated-web-forms.html

Pls advise how to adopt this to login to http://www.forex-tsd.com .

Thanks in advance.

pjo,

To modify Shay's function for your forum, you will need to look at the page source for your forum login screen. You can replace the "Email" with whatever the ID defines the box where you put your username in this line $ie.document.getElementById("Email").value=$uname.

Same with the password line.

I would also change the function name and default URL, to something like this:

function Login-Forex{
param(
[string]$uname,
[string]$url="http://www.forex-tsd",
[bool]$cookie=$FALSE
)

$creds = get-credential $uname
$pass = $creds.GetNetworkCredential().Password
$ie=new-object -com internetexplorer.application
$ie.visible=$TRUE
$ie.navigate($url)
while($ie.ReadyState -ne 4) {start-sleep -m 100}
$ie.document.getElementById("vb_login_username").value=$uname
$ie.document.getElementById("vb_login_password").value = $pass
$ie.document.getElementsByName("PersistentCookie") | foreach {$_.checked=$cookie}
$ie.document.getElementById("Log In").submit()
}

I don't have an account on those forums, so I can't check if it works, but give it a try.

This is another version:

 $url = " http://www.forex-tsd.com/expert-analysis/801-weekly-winners.html"
# $url = " http://www.forex-tsd.com/indicators-metatrader-4/"
$user = "username"
$pass = "passwordi"

$ie=new-object -com internetexplorer.application
$ie.visible=$true
$ie.navigate($url)

# wait for the page to load completely
# while($ie.ReadyState -ne 4) {start-sleep -m 1000} 
while($ie.busy) {start-sleep 1}
  

# update the values of the login form (the one on the upper right hand side)
Start-Sleep -Seconds 10
$ie.document.getElementById("navbar_username").value=$user
$ie.document.getElementById("navbar_password").value=$pass

# there are at list 7 forms on this page, you need the one
# where "do=login" appears in its action property
# $forms array contains all the forms in the page
# piping it to where-object to filter all that match "do=login"
# and submitting the first one
Start-Sleep -Seconds 10
$forms = @($ie.Document.forms | where {$_.action -match "do=login"})
Start-Sleep -Seconds 10
$forms[0].submit()

# wait for the page to load completely
#while($ie.ReadyState -ne 4) {start-sleep -m 1000}
while($ie.busy) {start-sleep 1}

# you're in
Start-Sleep -Seconds 10
$last = @($ie.document.getElementsByTagName("A")) | where {$_.innerText -eq 'Last »'}
while($ie.busy) {start-sleep 1}
Start-Sleep -Seconds 10
$ie.navigate($last[0].href)
# $ie.navigate($last.href)
# while($ie.ReadyState -ne 4) {start-sleep -m 1000}
 while($ie.busy) {start-sleep 1}

# last page loaded

 

This let me login to a private nonfree forum.

http://www.forex-tsd.com/indicators-metatrader-4/ is a free public forum.

Strange phenomena is that if above Start-sleep statements are deleted, no success to login on Vista.

What would be the cause of this ?

Does it indicate that loading the page is just taking a long time ?

The next step is to perform some string prossesing:

After loading the $ie,

browse to the last page of that forum.

Then,

Select-String the loaded $ie for a string AAABBB.

And I am in trouble there.

I tried

$wc = New-Object System.Net.WebClient

$wc.DownloadString($ie) > d:\work\test.html
$d　= $ie.document.body.innerhtml

$a = Select-String -Path d:\work\test.html -pattern " EURUSD:
"
 $a[-1].ToString().Split(":")

 

$wc.DownloadString("http://www.google.com") is fine, I think.

How should be the download statement with $ie ?

 

 

For some reason the navbar_username gets null.

So if navbar_username and navbar_password is null, $user and $pass should be submitted.
How could this be done ?

function Login-Forex{
param(
[string]$uname,
[string]$url="http://www.forex-tsd.com/",
[bool]$cookie=$FALSE
)

$creds = get-credential $uname
$pass = $creds.GetNetworkCredential().Password
$user = $creds.GetNetworkCredential().username
$ie=new-object -com internetexplorer.application
$ie.visible=$FALSE
$ie.navigate($url)
# while($ie.ReadyState -ne 4) {start-sleep -Milliseconds 1}
Start-Sleep -Seconds 5

$ie.document.getElementById("navbar_username").value = $user
$ie.document.getElementById("navbar_password").value = $pass
# $ie.document.getElementsByName("PersistentCookie") | foreach {$_.checked=$cookie}
$forms = @($ie.Document.forms | where {$_.action -match "do=login"})
Start-Sleep -Seconds 5
# $ie.document.getElementById("Log In").submit()
$forms[0].submit()
}

Login-Forex xxxx

This forum is free public registration required forum.

Thanks in advance.

Ｈｉ！

while($ie.ReadyState -ne 4) {start-sleep -Milliseconds 1}

$ie never gets ready while the page is loaded ok.

What would be the cause of this ?

Hi!

 

I asked the same or related question in the other forum and i got response.

It is Vista/IE7 problem.

Be aware Vista users !  PowerShell on Vista does not run correctly regarding IE7.
