Error Handling
|
|
==============
|
|
|
|
Errors are inevitable when working with the API, and they must be correctly handled with ``try..except`` blocks.
|
|
|
|
There are many errors that Telegram could return, but they all fall in one of these categories
|
|
(which are in turn children of the :obj:`RPCError <pyrogram.RPCError>` superclass):
|
|
|
|
- :obj:`303 - See Other <pyrogram.errors.SeeOther>`
|
|
- :obj:`400 - Bad Request <pyrogram.errors.BadRequest>`
|
|
- :obj:`401 - Unauthorized <pyrogram.errors.Unauthorized>`
|
|
- :obj:`403 - Forbidden <pyrogram.errors.Forbidden>`
|
|
- :obj:`406 - Not Acceptable <pyrogram.errors.NotAcceptable>`
|
|
- :obj:`420 - Flood <pyrogram.errors.Flood>`
|
|
- :obj:`500 - Internal Server Error <pyrogram.errors.InternalServerError>`
|
|
|
|
As stated above, there are really many (too many) errors, and in case Pyrogram does not know anything yet about a
|
|
specific one, it raises a special :obj:`520 Unknown Error <pyrogram.errors.UnknownError>` exception and logs it
|
|
in the ``unknown_errors.txt`` file. Users are invited to report these unknown errors; in later versions of Pyrogram
|
|
some kind of automatic error reporting module might be implemented.
|
|
|
|
Examples
|
|
--------
|
|
|
|
.. code-block:: python
|
|
|
|
from pyrogram.errors import (
|
|
BadRequest, Flood, InternalServerError,
|
|
SeeOther, Unauthorized, UnknownError
|
|
)
|
|
|
|
try:
|
|
...
|
|
except BadRequest:
|
|
pass
|
|
except Flood:
|
|
pass
|
|
except InternalServerError:
|
|
pass
|
|
except SeeOther:
|
|
pass
|
|
except Unauthorized:
|
|
pass
|
|
except UnknownError:
|
|
pass
|
|
|
|
Exception objects may also contain some informative values.
|
|
E.g.: :obj:`FloodWait <pyrogram.errors.exceptions.flood_420.FloodWait>` holds the amount of seconds you have to wait
|
|
before you can try again. The value is always stored in the ``x`` field of the returned exception object:
|
|
|
|
.. code-block:: python
|
|
|
|
import time
|
|
from pyrogram.errors import FloodWait
|
|
|
|
try:
|
|
...
|
|
except FloodWait as e:
|
|
time.sleep(e.x)
