Form Value Won't Post/Submit

[SuperMetroid]

The html code of the form, and my code are below. I can't get the value to post/submit.. instead I get an error. Can anyone help?

HTML Code of Form:

<form method='post' autocomplete='off'>
    <input type='hidden' name='action' value='grant-revoke' />
    <input type='hidden' name='creator_badge_index' value='1' />
 
    <input type='hidden' name='token' value='92dcd92a8bc16f73f330d118ae1ed891' />
    <input type='hidden' name='do-grant' value='1' />
    <div id='grant-div'><span class='label'>Grant badge: </span><input type='text' id='grant-userid' name='grant-userid' value='userid / avatar name' /><input type='submit' value='Grant!' /></div>
</form>

My Code:

opener = urllib.request.build_opener()
cj = http.cookiejar.MozillaCookieJar()
cj.load('C:/Users/Alison/Documents/moz_cookies.txt')
opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))
 
params = urllib.parse.urlencode({'grant-userid' : 'Guest_xLolKittyx'})
form = urllib.request.OpenerDirector.open('http://www.imvu.com/catalog/web_manage_badges.php?action=grant-revoke&creator_badge_index=1', params)
data = form.read()
form.close()
print(data)

Error Message:

You are mixing GET-type (indicated by ? in the URL) and POST-type
parameters. Put the action and creator_badge_index parameters also in
the dictionary. And probably you need to provide the other hidden fields
from the form also.

Something like (untested):

paramdict = {
          'action': 'grant-revoke',
          'creator_badge_index': '1',
          'token': '92dcd92a8bc16f73f330d118ae1ed891',
          'do-grant': '1',
          'grant-userid' : 'Guest_xLolKittyx',
          }
params = urllib.parse.urlencode(paramdict)
url = 'http://www.imvu.com/catalog/web_manage_badges.php'
form = urllib.request.OpenerDirector.open(url, params)

Thanks for the response! I changed the code, but I still get an error when it is run.. :/

Oh, and I tried it without the hidden fields as well, but I still get an error.

OK, there is another problem that I overlooked.

form = urllib.request.OpenerDirector.open(url, params)

is the wrong way to send the request. OpenerDirector.open is an instance method of the class OpenerDirector, not a class method. So that only works if you make an instance and then call the method on that. Like:

opener = urllib.request.build_opener(....)
form = opener.open(url, params)

That is only useful if you want a special opener, for example with authentication. In the simple cases you can get away with the standard opener by using urlopen:

form = urllib.request.urlopen(url, params)

(this one tested)

I'll close this thread, since Piet is helping me elsewhere. Thanks for everything Piet!
