Suggestion: searching by author

[gustaavv]

Searching by author, or viewing all doujinshi of a author, is a useful function to me.

We can observe that the artist page and the search page are quite alike (maybe the same) in nhentai.

So, I added a function to nhentai.py:

# add by elnino
    def search_by_author(self,
                         author: str,
                         page: int,
                         ) -> SearchResult:
        request_response = self.__make_request(url=f'https://nhentai.net/artist/{author}',
                                               params={'page': page})
        query = 'artist/' + author
        # below code is the same as the search() function
        soup = BeautifulSoup(request_response.text, 'html.parser')

        search_results_container = soup.find('div', {'class': 'container'})
        pagination_container = soup.find('section', {'class': 'pagination'})

        last_page_a_tag = pagination_container.find('a',
                                                    {'class': 'last'}) if pagination_container else None  # type: ignore
        total_pages = int(last_page_a_tag['href'].split('=')[-1]) if last_page_a_tag else 1  # type: ignore

        if not search_results_container:
            return SearchResult(query=query,
                                total_pages=total_pages,
                                page=page,
                                total_results=0,
                                results=[])

        search_results = search_results_container.find_all('div', {'class': 'gallery'})  # type: ignore

        if not search_results:
            return SearchResult(query=query,
                                total_pages=total_pages,
                                page=page,
                                total_results=0,
                                results=[])

        a_tags_with_doujin_id = [gallery.find('a', {'class': 'cover'}) for gallery in search_results]

        thumbs = []

        for a_tag in a_tags_with_doujin_id:
            if a_tag is None: continue

            doujin_id = a_tag['href'].split('/')[-2]

            if doujin_id == '': continue

            result_cover = a_tag.find('img', {'class': 'lazyload'})
            cover_uri = None
            width = None
            height = None

            if result_cover is not None:
                cover_uri = result_cover['data-src']
                width = result_cover['width']
                height = result_cover['height']

            result_caption = a_tag.find('div', {'class': 'caption'})

            caption = None
            if result_caption is not None:
                caption = result_caption.text

            thumbs.append(Thumb(id=doujin_id,
                                cover=Image(uri=cover_uri or '',
                                            mime=MIME.J,
                                            width=width or 0,
                                            height=height or 0),
                                title=caption or ''))

        return SearchResult(query=query,
                            total_pages=total_pages,
                            page=page,
                            total_results=25 * total_pages if pagination_container else len(thumbs),
                            results=thumbs)

and tested with the following code:

config = CloudFlareConfig(
    user_agent='',
    cf_clearance=''
)

nHentai = NHentai(config)
resultList = nHentai.search_by_author('yd', 1).results
for result in resultList:
    print(result)

and it works.

Similarily, the tag page can also be searched in this way.

So, I think the process of parsing html can be abstracted to a common function, which can be called by search(), search_by_author() and search_by_tag().

I am not good at python, and the above function is enough for my use. So I make this as an issue, instead of a PR.

since i have no idea what is going on .is there a way to get number of pages?
