E-hentai: TypeError during download.

[Nippey]

Hi, I got an error while downloading from e-hentai. Previous downloads of other galleries succeeded. Below is the verbose output as requested by the error message

Hi, nevermind!

I fetched the URL with WGET to check what text.unescape(data["title"]) was trying to parse:
This gallery has been flagged as Offensive For Everyone

So, I follwed the recommended procedure and created a user account .. working now!

I will not close this right away, as I have a proposal:

If this kind of banner comes up, I am still able to contine by clicking "View Gallery". Maybe this can be integrated into the extractor.

Thanks for reporting this and "investigating" a bit ... makes writing a solution a lot easier.

If I do a proposal for free software, I might as well provide some ideas in code ;)

Basically, I think about two methods. A: Warn the user to use credentials (not tested) B: Try again by skipping the warning (tested, working for me!)

You can find both below.

@staticmethod
def _is_offensive(response):
    """Return True if the response object contains a 'fallges as offensive' warning"""
    return (
        "Content Warning" in response.text
    )

"""Option A: Just Warn about it"""
class OffensiveError(ExtractionError):
    """Gallery is flagged offensive and should be donwloaded with login credentials"""

def request(self, *args, **kwargs):
    response = Extractor.request(self, *args, **kwargs)
    if self._is_sadpanda(response):
        self.log.info("sadpanda.jpg")
        raise exception.AuthorizationError()
    if  self._is_offensive(response):
        self.log.info("Offensive Gallery: Please provice credentials to continue")
        raise exception.OffensiveError()
    return response

"""Option B: Try to skip it"""
def request(self, *args, **kwargs):
    response = Extractor.request(self, *args, **kwargs)
    if self._is_sadpanda(response):
        self.log.info("sadpanda.jpg")
        raise exception.AuthorizationError()
    if  self._is_offensive(response):
        self.log.info("Offensive Gallery: Skipping Warning")
        ## Add request flag "?nw=always" to <url> parameter
        args = list(args)
        args[0] = args[0] + "?nw=always"
        args = tuple(args)
        ## Is it okay this way??
        response = Extractor.request(self, *args, **kwargs)
    return response

Already solved, that was fast o.o Thanks!!
