flask-telegram-login's Issues

Absence of user last_name causes TypeError

I was getting TypeError when I tried to login. I figured out after putting some debug code that the "last_name" in

Keys have the following:

['auth_date', 'first_name', 'id', 'last_name', 'username']

When in comes to last_name in the iteration in for key in keys:it fails.

    string_arr.append(key+'='+data[key])
TypeError: can only concatenate str (not "NoneType") to str

flask-telegram-login/app.py

Line 28 in 3b1fd43

string_arr.append(key+'='+data[key])

I worked around it by putting a last name and it logged successfully.

Live demo seems down

Demo link in readme doesn't work

hash key is not correct when some returned parameters are missing

Hello there,

When some request.args.get() is missing (in my case, no "photo_url") and None is returned as the default value, key + '=' + data[key] would result in error since data[key] is None. I have tried checking for None value, to skip the whole key + '=' + data[key] line, or make it to be key + '=' + '', both give a wrong hash.

May you please help take a look on this?

Thanks.
