Python TikTokApi SynchronousOnlyOperation error

Question

I have a Django project where I am trying to fetch TikTok user info from a class based django view. I am running into an issue that appears to be related to async/sync/threading.

Related documents: https://docs.djangoproject.com/en/3.2/topics/async/

I tried decorating views described in the link above still no luck. I added this bit of code to my gunicorn wsgi file os.environ.setdefault("DJANGO_ALLOW_ASYNC_UNSAFE", "true") which does fix the problem but seems like a bad idea.

Here is the bit of code that I am using to call the TikTokAPI:

def get_user_info(username):
    verify_fp = "code here"
    try:
        api = TikTokApi(custom_verify_fp=verify_fp)
        user = api.user(username=username)
        info = user.info_full()
        return info
    except Exception:
        return None

class TikTokAccount(APIView):

    def post(self, request, *args, **kwargs):
        ...
        info = get_user_info(username)
        ...

Traceback (most recent call last):

Any ideas on how to resolve?

Answer 1

I haven't tried out my TikTokApi package on Django, but yeah it's got some threading issues right now which I'm planning to fix hopefully sometime in the next two weeks or so.

In the meantime, someone made a PR that might help you out with the threading issues https://github.com/davidteather/TikTok-Api/pull/846 the syntax changed in that PR to using a with statement. I'm going to try to make it an optional with statement when that PR gets merged into master eventually.
