HTTP Error 307: Temporary Redirect in Python3 - INTRANET

问题

The code generates a series of URLs and searches them for a specific string. As the website requires login information:

I logged in the website through my browsers.
And for more checks, I tried only one complete URL(of the same website) with no values and encoding and it worked perfectly well. So I supposed the login information shouldn't be the problem.
I did try to add log-in info through the code, but as it itself brought up a series of errors, I wanted to see if that is really necessary to work on. Maybe there is another solution with no need to log-in.
Lately, I understood the link is in "intranet" not "internet". Can that be the problem?

This is the code:

         url ='https://www.aug.ipp.mpg.de/cgibin/sfread_only/isis?'

    shotn = shot_a
    #Shot_a, shot_z, diag and param are user inputs.
    enter code here
    while (shotn <= shot_z):
        values = {'shot': shotn,
                  'exp': 'AUGD',
                  'diag': diag ,
                  'action': 'SignalDetails',
                  'signal': param}



       data = urllib.parse.urlencode(values)
        data = data.encode('utf-8')
        req = urllib.request.Request(url, data)
        resp = urllib.request.urlopen(req)
       #The upper line is line 42- the first error
        respData = resp.read()
       shotn +=1

The expected result would be a .txt file in the computer which includes the shotn's which that specific statement was found in the corresponding URL.

And this is actual result:
