AuthenticatedUser.get_name() still returns empty string pylast 3.1.0

[Qwerty-Space]

What did you do?

Specifically the contents of main()
I tried to print my username using the AuthenticatedUser class

What did you expect to happen?

I expected it to print my username

What actually happened?

It prints an empty string

What versions of OS, Python and pylast are you using?

Manjaro 18.0.4 Illyria

>>> pylast.__version__
'3.1.0'

$ python -V
Python 3.7.2

Code

Python Code:

import time
import pylast
from os import path
from config import api_key, api_secret

script_dir = path.dirname(path.realpath(__file__))  # Set the location of the script
session_file = path.join(script_dir, "python-lastfm.session_key")

network = pylast.LastFMNetwork(api_key=api_key, api_secret=api_secret)

def login():
    skg = pylast.SessionKeyGenerator(network)
    url = skg.get_web_auth_url()

    print(f"Please follow the link to authorise your account:\n\n{url}")

    time.sleep(3)

    while True:
        try:
            session_key = skg.get_web_auth_session_key(url)
            with open(session_file, "w") as f:
                f.write(session_key)
            print("Signed in!")
            break
        except pylast.WSError:
            time.sleep(3)

def main():
    print("Hi")
    u = network.get_authenticated_user()
    print(u, u.get_name())


if __name__ == "__main__":
    if not path.exists(session_file):
        login()
    else:
        session_key = open(session_file).read()
        network.session_key = session_key
        main()

I have the same issue. Also If I try to do this

print(skg.get_web_auth_session_key_username(url))

The programm just waits forever.

Confirming this issue. It seems that AuthenticatedUser doesn't set the username. It also propagates to any user methods that require the username to be set. Workaround: provide a username in the network constructor:

# Works
pylast = LastFMNetwork(getenv('LASTFM_API'), getenv('LASTFM_SECRET'), user.token, user.name)
history = pylast.get_authenticated_user().get_recent_tracks()

# Doesn't work
pylast = LastFMNetwork(getenv('LASTFM_API'), getenv('LASTFM_SECRET'), user.token)
history = pylast.get_authenticated_user().get_recent_tracks()

The broken example results in the following trace:

INFO:pylast:user.getRecentTracks
INFO:pylast:user.getRecentTracks
