Token: regexp never finds anything

Hello,

I know the code yielding this error is not in this repository but the gtts-token repository seems inactive…

Since a few hours ago it seems that one of the regular expressions when searching “TKK=‘integer.integer’;” in Google Translate HTTP response doesn’t find anything.

Here is my Traceback:

gtts-cli 'hello' --output hello.mp3
Traceback (most recent call last):
  File "/usr/local/bin/gtts-cli", line 9, in <module>
    load_entry_point('gTTS==2.0.1', 'console_scripts', 'gtts-cli')()

    part_tk = self.token.calculate_token(part)

    seed = self._get_token_key()
  File "/usr/local/lib/python2.7/dist-packages/gtts_token/gtts_token.py", line 62, in _get_token_key
    a = re.search("a\\\\x3d(-?\d+);", tkk_expr).group(1)
AttributeError: 'NoneType' object has no attribute 'group'

Is it possible this is caused by a modification in Google Translate HTTP response? I tried with other google translate python apps and they also fail to find the token…

Best regards, Thomas

gTTS-token 1.1.2 has just been released. Thanks a lot for the work everyone. It’s good to see something I’ve created years ago still being cared about.

That’s hard to say as this exception is the result of a faulty regex handler in another repo (for which I’ve submitted a pull request for) that is rather inactive as of now.

However, in the meantime you can monkey-patch the affected function like so:

import calendar
import time
import math
import re
import requests
from gtts import gTTS
from gtts_token.gtts_token import Token

def _patch_faulty_function(self):
    if self.token_key is not None:
        return self.token_key

    timestamp = calendar.timegm(time.gmtime())
    hours = int(math.floor(timestamp / 3600))

    response = requests.get("https://translate.google.com/")
    line = response.text.split('\n')[-1]

    parsed = re.search("(?:TKK='(?:(\d+)\.(\d+))';)", line)
    a, b = parsed.groups()

    result = str(hours) + "." + str(int(a) + int(b))
    self.token_key = result
    return result


# Monkey patch faulty function.
Token._get_token_key = _patch_faulty_function

# Then call it normally.
tts = gTTS('hello')
tts.save('hello.mp3')

I hope that helps.
