Enter into web page recursively using invoke-webrequest

Question

This is how I authorize to web page using Invoke-WebRequest command right now:
$web = Invoke-WebRequest https://mypage/ -SessionVariable gos
$forms = $web.Forms[0]
$forms.Fields["username"] = "[email protected]"
$forms.Fields["password"] = "pass"
$web_invoke = Invoke-WebRequest -Uri ("https://mypage" + $forms.Action) -WebSession $matt -Method Post -Body 
$web_invoke.StatusDescription
Thing is that I have to login once again when I logged into first webpage to reach another service.
I have traced logid_ID and passsword_ID as well as button that will transfer me to the needed page.
How can I combine these two logins in one script?

Hi Kirillpashkov,
If you want to sign in web service, the example below is for your reference, which could sign in to the Facebook web service:
# Sends a sign-in request by running the Invoke-WebRequest cmdlet. The command specifies a value of "fb" for the SessionVariable parameter, and saves the results in the $r variable.
$r=Invoke-WebRequest http://www.facebook.com/login.php -SessionVariable fb
# Use the session variable that you created in Example 1. Output displays values for Headers, Cookies, Credentials, etc.
$fb
# Gets the first form in the Forms property of the HTTP response object in the $r variable, and saves it in the $form variable.
$form = $r.Forms[0]
# Pipes the form properties that are stored in the $forms variable into the Format-List cmdlet, to display those properties in a list.
$form | Format-List
# Displays the keys and values in the hash table (dictionary) object in the Fields property of the form.
$form.fields
# The next two commands populate the values of the "email" and "pass" keys of the hash table in the Fields property of the form. Of course, you can replace the email and password with values that you want to use.
$form.Fields["email"] = "[email protected]"
$form.Fields["pass"] = "P@ssw0rd"
# The final command uses the Invoke-WebRequest cmdlet to sign in to the Facebook web service.
$r=Invoke-WebRequest -Uri ("https://www.facebook.com" + $form.Action) -WebSession $fb -Method POST -Body $form.Fields
