crash in AppPixivAPI.parse_qs

for i in range(1, 200): for illust in json_result.illusts: if i is 1: json_result = aapi.illust_follow(req_auth=True) else: # get next page next_qs = aapi.parse_qs(json_result.next_url) json_result = aapi.illust_follow(req_auth=True, **next_qs)

this code runs fine for the first five but then I get json_result = aapi.illust_follow(req_auth=True, **next_qs) TypeError: illust_follow() argument after ** must be a mapping, not NoneType

It happens when there are no more pages. Try this:

from pixivpy3 import AppPixivAPI


def main():
    aapi = AppPixivAPI()
    aapi.login('username', 'password')

    next_qs = {}
    while next_qs is not None:
        json_result = aapi.illust_follow(**next_qs)
        # do something with json_result
        next_qs = aapi.parse_qs(json_result.next_url)


if __name__ == '__main__':
    main()

1. You should not make an assumption that you can perform the iteration for 200 times. And there is no documentation mentions that json_result.next_url will not become None after reaching the last page. Using a while loop is much more safe. This is what I said “caused by your code”, they are not safe enough.

2. Even on the desktop there is still a limit on following illustrations. For regular user the limitation is 2000, and for premium user it is 5000.
