Fur Affinity API

Python library to implement API-like functionality for the Fur Affinity website.

Requirements

Python 3.9+ is necessary to run this library. Poetry is used for packaging and dependency management.

Usage

The API comprises a main class FAAPI, two submission classes Submission and SubmissionPartial, a journal class Journal, and a user class User.

Once FAAPI is initialized, its methods can be used to crawl FA and return parsed objects.

from requests.cookies import RequestsCookieJar
import faapi
import orjson

cookies = RequestsCookieJar()
cookies.set("a", "38565475-3421-3f21-7f63-3d341339737")
cookies.set("b", "356f5962-5a60-0922-1c11-65003b70308")

api = faapi.FAAPI(cookies)
sub, sub_file = api.submission(12345678, get_file=True)

print(sub.id, sub.title, sub.author, f"{len(sub_file) / 1024:02f}KiB")

with open(f"{sub.id}.json", "wb") as f:
    f.write(orjson.dumps(dict(sub)))

with open(sub.file_url.split("/")[-1], "wb") as f:
    f.write(sub_file)

gallery, _ = api.gallery("user_name", 1)
with open("user_name-gallery.json", "wb") as f:
    f.write(orjson.dumps(list(map(dict, gallery))))

robots.txt

At init, the FAAPI object downloads the robots.txt file from FA to determine the Crawl-delay and disallow values set therein. If not set in the robots.txt file, a crawl delay value of 1 second is used.

To respect this value, the default behaviour of the FAAPI object is to wait when a get request is made if the last request was performed more recently then the crawl delay value.

See under FAAPI for more details on this behaviour.

Furthermore, any get operation that points to a disallowed path from robots.txt will raise an exception. This check should not be circumvented, and the developer of this library does not take responsibility for violations of the TOS of Fur Affinity.

Cookies

To access protected pages, cookies from an active session are needed. These cookies can be given to the FAAPI object as a list of dictionaries - each containing a name and a value field -, or as a http.cookiejar.CookieJar object (requests.cookies.RequestsCookieJar and other objects inheriting from CookieJar are also supported). The cookies list should look like the following example:

cookies = [
    {"name": "a", "value": "38565475-3421-3f21-7f63-3d3413397537"},
    {"name": "b", "value": "356f5962-5a60-0922-1c11-65003b703038"},
]
from requests.cookies import RequestsCookieJar

cookies = RequestsCookieJar()
cookies.set("a", "38565475-3421-3f21-7f63-3d3413397537")
cookies.set("b", "356f5962-5a60-0922-1c11-65003b703038")

To access session cookies, consult the manual of the browser used to log in.

Note: it is important to not logout of the session the cookies belong to, otherwise they will no longer work.
Note: as of April 2022 only cookies a and b are needed.

User Agent

FAAPI attaches a User-Agent header to every request. The user agent string is generated at startup in the following format: faapi/{library version} Python/{python version} {system name}/{system release}.

Objects

FAAPI

This is the main object that handles all the calls to scrape pages and get submissions.

It holds 6 different fields:

  • session: requests.Session The session used for all requests.
  • robots: urllib.robotparser.RobotFileParser robots.txt handler
  • user_agent: str user agent used by the session (property, cannot be set)
  • crawl_delay: float crawl delay from robots.txt (property, cannot be set)
  • last_get: float time of last get (UNIX time)
  • raise_for_unauthorized: bool = True if set to True, raises an exception if a request is made and the resulting page is not from a login session
  • timeout: int | None = None requests timeout in seconds for both page requests (e.g. submissions) and files

Init

__init__(cookies: list[dict[str, str]] | CookieJar, session_class: Type[Session] = Session)

A FAAPI object must be initialised with a cookies object in the format mentioned above in #Cookies.

An optional session_class argument can be given to modify the class used by FAAPI.session. Any class based on requests.Session is accepted.

Methods & Properties

  • load_cookies(cookies: list[dict[str, str]] | CookieJar)
    Load new cookies and create a new session.
    Note: This method removes any cookies currently in use, to update/add single cookies access them from the session object.
  • handle_delay()
    Handles the crawl delay as set in the robots.txt
  • check_path(path: str, *, raise_for_disallowed: bool = False) -> bool
    Checks whether a given path is allowed by the robots.txt. If raise_for_disallowed is set to True a DisallowedPath exception is raised on non-allowed paths.
  • connection_status -> bool
    Returns the status of the connection.
  • login_status -> bool
    Returns the login status.
  • get(path: str, **params) -> requests.Response
    This returns a response object containing the result of the get operation on the given URL with the optional **params added to it (url provided is considered as path from 'https://www.furaffinity.net/').
  • get_parsed(path: str, *, skip_page_check: bool = False, skip_auth_check: bool = False, **params) -> bs4.BeautifulSoup
    Similar to get() but returns the parsed HTML from the normal get operation. If the GET request encountered an error, an HTTPError exception is raised. If skip_page_check is set to True, the parsed page is not checked for errors ( e.g. non-existing submission). If skip_auth_check is set to True, the page is not checked for login status.
  • me() -> User | None
    Returns the logged-in user as a User object if the cookies are from a login session.
  • frontpage() -> list[SubmissionPartial]
    Fetch the latest submissions from Fur Affinity's front page.
  • submission(submission_id: int, get_file: bool = False, *, chunk_size: int = None) -> tuple[Submission, bytes | None]
    Given a submission ID, it returns a Submission object containing the various metadata of the submission itself and a bytes object with the submission file if get_file is passed as True. The optional chunk_size argument is used for the request; if left to None or set to 0 the download is performed directly without streaming.
    Note: the author UserPartial object of the submission does not contain the join_date field as it does not appear on submission pages.
  • submission_file(submission: Submission, *, chunk_size: int = None) -> bytes
    Given a submission object, it downloads its file and returns it as a bytes object. The optional chunk_size argument is used for the request; if left to None or set to 0 the download is performed directly without streaming.
  • journal(journal_id: int) -> Journal
    Given a journal ID, it returns a Journal object containing the various metadata of the journal.
  • user(user: str) -> User
    Given a username, it returns a User object containing information regarding the user.
  • gallery(user: str, page: int = 1) -> tuple[list[SubmissionPartial], int | None]
    Returns the list of submissions found on a specific gallery page, and the number of the next page. The returned page number is set to None if it is the last page.
  • scraps(user: str, page: int = 1) -> -> tuple[list[SubmissionPartial], int | None]
    Returns the list of submissions found on a specific scraps page, and the number of the next page. The returned page number is set to None if it is the last page.
  • favorites(user: str, page: str = "") -> tuple[list[SubmissionPartial], str | None]
    Downloads a user's favorites page. Because of how favorites pages work on FA, the page argument (and the one returned) are strings. If the favorites page is the last then a None is returned as next page. An empty page value as argument is equivalent to page 1.
    Note: favorites page "numbers" do not follow any scheme and are only generated server-side.
  • journals(user: str, page: int = 1) -> -> tuple[list[JournalPartial], int | None]
    Returns the list of submissions found on a specific journals page, and the number of the next page. The returned page number is set to None if it is the last page.
  • watchlist_to(self, user: str, page:int = 1) -> tuple[list[UserPartial], int | None]
    Given a username, returns a list of UserPartial objects for each user that is watching the given user and the next page, if it is not the last, in which case a None is returned.
  • watchlist_by(self, user: str, page:int = 1) -> tuple[list[UserPartial], int | None]
    Given a username, returns a list of UserPartial objects for each user that is watched by the given user and the next page, if it is not the last, in which case a None is returned.

Note: The last page returned by the watchlist_to and watchlist_by may not be correct as Fur Affinity doesn't seem to have a consistent behaviour when rendering the next page button, as such it is safer to use an external algorithm to check whether the method is advancing the page but returning the same/no users.

UserPartial

A stripped-down class that holds basic user information. It is used to hold metadata gathered when parsing a submission, journal, gallery, scraps, etc.

  • name: str display name with capital letters and extra characters such as "_"
  • status: str user status (~, !, etc.)
  • title: str the user title as it appears on their userpage
  • join_date: datetime the date the user joined (defaults to timestamp 0)
  • avatar_url: str the URL to the user icon (used only when available)
  • user_tag: bs4.element.Tag the user element used to parse information (placeholder, UserPartial is filled externally)

UserPartial objects can be directly cast to a dict object and iterated through.

Comparison with UserPartial can be made with either another UserPartial or User object (the URL names are compared), or a string (the URL name is compared to the given string).

Init

__init__(user_tag: bs4.element.Tag = None)

To initialise the object, an optional bs4.element.Tag object is needed containing the user element from a user page or user folder.

If no user_tag is passed then the object fields will remain at their default - empty - value.

Methods

  • name_url -> str
    Property method that returns the URL-safe username
  • url -> str
    Property method that returns the Fur Affinity URL to the user (https://www.furaffinity.net/user/{name_url}).
  • generate_avatar_url() -> str
    Generates the URl for the current user icon.
  • parse(user_page: bs4.BeautifulSoup = None)
    Parses the stored user page for metadata. If user_page is passed, it overwrites the existing user_page value.

  • comments: list[Comments] the comments to the submission, organised in a tree structure
  • submission_page: bs4.BeautifulSoup the submission page used to parse the object fields

Submission objects can be directly cast to a dict object and iterated through.

Comparison with Submission can be made with either another Submission or SubmissionPartial object (the IDs are compared), or an integer (the Submission.id value is compared to the given integer).

Init

__init__(submission_page: bs4.BeautifulSoup = None)

To initialise the object, an optional bs4.BeautifulSoup object is needed containing the parsed HTML of a submission page.

If no submission_page is passed then the object fields will remain at their default - empty - value.

Methods

  • url -> str
    Property method that returns the Fur Affinity URL to the submission (https://www.furaffinity.net/view/{id}).
  • parse(submission_page: bs4.BeautifulSoup = None)
    Parses the stored submission page for metadata. If submission_page is passed, it overwrites the existing submission_page value.

Comment

This object class contains comment metadata and is used to build a tree structure with the comments and their replies.

  • id: int the comment ID
  • author: UserPartial the user who posted the comment
  • date: datetime the date the comment was posted
  • text: str the comment text in HTML format
  • text_bbcode: str the comment text in BBCode format
  • replies: list[Comment] list of replies to the comment
  • reply_to: Comment | int | None the parent comment, if the comment is a reply. The variable type is int only if the comment is parsed outside the parse method of a Submission or Journal (e.g. by creating a new comment with a comment tag), and when iterating over the parent object (to avoid infinite recursion errors), be it Submission , Journal or another Comment.
  • edited: bool True if the comment was edited, False otherwise
  • hidden: bool True if the comment was hidden, False otherwise (if the comment was hidden, the author and date fields will default to their empty values)
  • parent: Submission | Journal | None the Submission or Journal object the comments are connected to
  • comment_tag: bs4.element.Tag the comment tag used to parse the object fields

Comment objects can be directly cast to a dict object and iterated through.

Comparison with Comment can be made with either another comment (the IDs are compared), or an integer ( the Comment.id value is compared to the given integer).

Note: The __iter__ method of Comment objects automatically removes recursion. The parent variable is set to None and reply_to is set to the comment's ID.
Note: Because each comment contains the parent Submission or Journal object (which contains the comment itself) and the replied comment object, some iterations may cause infinite recursion errors, for example when using the copy.deepcopy function. If such iterations are needed, simply set the parent variable to None and the reply_to variable to None or the comment's ID (this can be done easily after flattening the comments list with faapi.comment.flatten_comments, the comments can then be sorted again with faapi.comment.sort_comments which will also restore the reply_to values to Comment objects).

Init

__init__(self, tag: bs4.element.Tag = None, parent: Submission | Journal = None)

To initialise the object, an optional bs4.element.Tag object is needed containing the comment tag as taken from a submission/journal page.

The optional parent argument sets the parent variable described above.

If no tag is passed then the object fields will remain at their default - empty - value.

Methods

  • url -> str
    Property method that returns the Fur Affinity URL to the comment ( e.g. https://www.furaffinity.net/view/12345678#cid:1234567890). If the parent variable is None, the property returns an empty string.
  • parse(tag: bs4.element.Tag = None)
    Parses the stored tag for metadata. If tag is passed, it overwrites the existing tag value.

Extra Functions

These extra functions can be used to operate on a list of comments. They only alter the order and structure, but they do not touch any of the metadata.

  • faapi.comment.sort_comments(comments: list[Comment]) -> list[Comment]
    Sorts a list of comments into a tree structure. Replies are overwritten.
  • faapi.comment.flatten_comments(comments: list[Comment]) -> list[Comment]
    Flattens a list of comments. Replies are not modified.

Comment Tree Graphs

Using the tree structure generated by the library, it is trivial to build a graph visualisation of the comment tree using the DOT language.

submission, _ = api.submission(12345678)
comments = faapi.comment.flatten_comments(submission.comments)
with open("comments.dot", "w") as f:
    f.write("digraph {\n")
    for comment in [c for c in comments if c.reply_to is None]:
        f.write(f"    parent -> {comment.id}\n")
    for comment in comments:
        for reply in comment.replies:
            f.write(f"    {comment.id} -> {reply.id}\n")
    f.write("}")
digraph {
    parent -> 157990848
    parent -> 157993838
    parent -> 157997294
    157990848 -> 158014077
    158014077 -> 158014816
    158014816 -> 158093180
    158093180 -> 158097024
    157993838 -> 157998464
    157993838 -> 158014126
    157997294 -> 158014135
    158014135 -> 158014470
    158014135 -> 158030074
    158014470 -> 158093185
    158030074 -> 158093199
}

BBCode Conversion

Using the BBCode fields allows to convert between the raw HTMl recovered from Fur Affinity and BBCode tags that follow FA's guidelines. Conversion from HTML to BBCode covers all known tags and preserves all newlines and spacing.

BBCode text can be converted to Fur Affinity's HTMl using the faapi.parse.bbcode_to_html() function. The majority of submissions can be converted back and forth between HTML and BBCode without any information loss, however, the parser rules are still a work in progress and there are many edge cases where unusual text and formatting cause the parser to generate incorrect HTML.

Exceptions

The following are the exceptions explicitly raised by the FAAPI functions. The exceptions deriving from ParsingError are chosen depending on the content of the page. Because Fur Affinity doesn't use HTTP status codes besides 404, the page is checked against a static list of known error messages/page titles in order to determine the specific error to be used. If no match is found, then the ServerError (if the page has the "Server Error" title) or the more general NoticeMessage exceptions are used instead. The actual error message parsed from the page is used as argument for the exceptions, so that it can be analysed when caught.

  • DisallowedPath(Exception) The path is not allowed by the robots.txt.
  • Unauthorized(Exception) The user is not logged-in.
  • ParsingError(Exception) An error occurred while parsing the page.
    • NonePage(ParsingError) The parsed page is None.
    • NotFound(ParsingError) The resource could not be found (general 404 page or non-existing submission, user, or journal).
    • NoTitle(ParsingError) The parsed paged is missing a title.
    • DisabledAccount(ParsingError) The resource belongs to a disabled account.
    • ServerError(ParsingError) The page contains a server error notice.
    • NoticeMessage(ParsingError) A notice of unknown type was found in the page.

Beautiful Soup Warnings

When parsing some pages or converting HTML to BBCode, the Beautiful Soup library may give some warnings, for example MarkupResemblesLocatorWarning. These warnings are left enabled for clarity, but can be disabled manually using the warnings.filterwarnings function.
