How would I use Invoke-WebRequest to post all these parameters
POST /token HTTP/1.1
Host: login.huddle.net
Content-Type: application/x-www-form-urlencoded
grant_type=authorization_code&client_id=s6BhdRkqt&redirect_uri=MyAppServer.com/receiveAuthCode&code=i1WsRn1uB
Here's how to convert that body into one which PowerShell can interpret.
$body = @{grant_type='authorization_code'
client_id='s6BhdRkqt'
redirect_uri='MyAppServer.com/receiveAuthCode'
code='i1WsRn1uB'}
$contentType = 'application/x-www-form-urlencoded'
Invoke-WebRequest -Method POST -Uri yourUrl -body $body -ContentType $contentType
Just work.
[psCustomObject]. However the Invoke-WebRequest cmdlets rely on us, the authors, to convert our -Body value to the right content type. In the modern Web that is almost always JSON for most APIs, but sometimes not. Contrast that with Invoke-Restmethod, which assumes you're working with Rest and so always converts the body value into JSON.Do something like that
$loginPage = Invoke-WebRequest "http:\\website.com\" # invoke login form page
$loginForm = $loginPage.Forms[0] # Get the form to fill
$loginForm.fields["userName"] = "usrnm" # fill the username
$loginForm.fields["password"] = "psswd" # fill the password
$loginPage = Invoke-WebRequest -Uri ("http:\\website.com\") -Method POST -Body $loginForm.fields # Post the form to log-in
