Python client for the Telegram's tdlib

python-telegram

Python API for the tdlib library. It helps you build your own Telegram clients.

• Changelog
• Documentation
• Tutorial

Installation

This library requires Python 3.8+ and Linux or MacOS. Windows is not supported.

pip install python-telegram

See documentation for more details.

Docker

This library has a docker image:

docker run -i -t --rm \
            -v /tmp/docker-python-telegram/:/tmp/ \
            akhmetov/python-telegram \
            python3 /app/examples/send_message.py $(API_ID) $(API_HASH) $(PHONE) $(CHAT_ID) $(TEXT)

How to use

Have a look at the tutorial :)

Basic example:

from telegram.client import Telegram
from telegram.text import Spoiler

tg = Telegram(
    api_id='api_id',
    api_hash='api_hash',
    phone='[phone]',  # you can pass 'bot_token' instead
    database_encryption_key='changekey123',
    files_directory='/tmp/.tdlib_files/',
)
tg.login()

# if this is the first run, library needs to preload all chats
# otherwise the message will not be sent
result = tg.get_chats()
result.wait()

chat_id: int
result = tg.send_message(chat_id, Spoiler('Hello world!'))
# `tdlib` is asynchronous, so `python-telegram` always returns you an `AsyncResult` object.
# You can receive a result with the `wait` method of this object.
result.wait()
print(result.update)

tg.stop()  # you must call `stop` at the end of the script

You can also use call_method to call any tdlib method:

tg.call_method('getUser',  params={'user_id': user_id})

More examples you can find in the /examples/ directory.

python-telegram's Issues

async_result.wait() is waiting forever. Solved!

Hello. I found a bag in source code of telegram.Telegram class!
In some cases, when using client's "call_method" function the returned async_result will never refresh. No errors, no updates. Just stacked in .wait() state. I have found decision. Just swap two lines in "_send_data" method of telegram.Telegram class.

BEFORE

    def _send_data(
        self, data: Dict[Any, Any], result_id: Optional[str] = None
    ) -> AsyncResult:
        if '@extra' not in data:
            data['@extra'] = {}

        if not result_id and 'request_id' in data['@extra']:
            result_id = data['@extra']['request_id']

        async_result = AsyncResult(client=self, result_id=result_id)
        data['@extra']['request_id'] = async_result.id

        self._tdjson.send(data)
        self._results[async_result.id] = async_result
        async_result.request = data

        return async_result

AFTER

    def _send_data(
            self, data: Dict[Any, Any], result_id: Optional[str] = None
    ) -> AsyncResult:
        if '@extra' not in data:
            data['@extra'] = {}

        if not result_id and 'request_id' in data['@extra']:
            result_id = data['@extra']['request_id']

        async_result = AsyncResult(client=self, result_id=result_id)
        async_result.request = data
        data['@extra']['request_id'] = async_result.id

        self._results[async_result.id] = async_result   # Поменял эти две строчки местами
        self._tdjson.send(data)                         # И все стало работать нормально...

        return async_result

Client wait for result forever if result update have only @type='ok'

Hello,

I play with master branch of python-telegram and found a bug. When I try to set my first/last name then AsyncResult wait forever. It happens because Event self._ready.set() in the AsyncResult is set only if update @type != 'ok'.
I guess it was made for login purposes where result @type='ok' is not means that result is ready.

This is my code:

   tg.login()

    result = tg.get_me()
    result.wait()
    print(result.update)

    logger.debug("Setting name")
    result = tg.call_method('setName', params={'first_name': 'First', 'last_name': 'Last'})
    result.wait() # there it waits forever
    print(result.update)

I changed the parse_update method of AsyncResult as follows by adding condition if self.id != 'updateAuthorizationState' and it start working.

    def parse_update(self, update: Dict[Any, Any]) -> None:
        if update.get('@type') == 'ok':
            self.ok_received = True
            # added following 3 lines
            if self.id != 'updateAuthorizationState':
                self._ready.set()
                return True
            return False

        if update.get('@type') == 'error':
            self.error = True
            self.error_info = update
        else:
            self.update = update

        self._ready.set()

        return True

But I not 100% sure that my way is correct, I just started to play with Telegram lib a day ago..

SetOptions() hangs when updating online status

Hello,

so I want to set the Online Status to online for using secret chats.

Therefore I firstly call the setOption function (link: https://core.telegram.org/tdlib/docs/classtd_1_1td__api_1_1set_option.html) as described in this issue from TDlib tdlib/td#714.

I'm using the newest version of TDlib (compiled by my own)

So my code after login:

### Yomam
tg = Telegram(
    api_id=XXXX,
    api_hash=XXXX,
    phone=XXXX,
    database_encryption_key=XXXX,
    library_path="XXXX/tdlib/lib/libtdjson.so.1.5.4"
)

tg.login()


#Set online status
data = {
    '@type': 'setOption',
    'name': 'online',
    'value': {
        '@type': 'optionValueBoolean',
        'value': True,
    },
}

result = tg._send_data(data)
result.wait()
print(result.update)

result = tg.call_method("getOption", params={'name':'online'})
result.wait()
print(result.update)

tg.idle()

Output is:

...
XXXX [INFO] telegram.client: Completing auth process

And then it hangs...

So any ideas how to handle this?

chat_ids are empty

Hello!
I'm trying to get my chats but receiving empty chat_ids list.

tg = Telegram(
    api_id=API_ID,
    api_hash=API_HASH,
    database_encryption_key='',
    library_path=PATH_TO_LIBTDJSON,
    phone=MY_PHONE
)
tg.login()

result = tg.get_chats()
result.wait()
print(result.update)

The result is

{'@type': 'chats', 'chat_ids': [], '@extra': {'request_id': 'acf2ec5fe1e442b0b507efd0687028ac'}}

What I'm doing wrong ?

libtdjson.so is doing allot of issues on Cent OS 7

I am facing a lot of issues regarding libtdjson.so in cent os 7.
OSError: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by /home/martyn/github/ultima-code/main/scrapers/telegram/telegram_bot_barksdale/telegram/lib/linux/libtdjson.so)

This is one of the issues. can you please help me to?

Use specific openssl ver

is it possible to provide my own version of openssl? i've installed via pip3 and it seems that libtdjson requires right only libssl.1.0.0, while there's libssl.1.1 available on my system

Upgrade docker image to use the latest tdlib

There is 1.3.0 already: https://github.com/tdlib/td/releases/tag/v1.3.0

Outdated tdlib

Hey since the tdlib library in the project is outdated, I would like compile the newest (1.5) version. But I don't know how, since there are several options...Could you tell me the command how you compiled the lib?

[Question] How to change autodownload settings / download remote files?

Hi!
Thanks for this awesome project! Can you please explain to me how to change auto download settings or to download any file manually? Also, can I manually delete downloaded file using
rm $some_tg_downloaded_file?

Again big thanks,
Andrew Ishutin

P. S. Should I open this issue in the TDLib repo?

handling flood_wait_ - example not working

Hey I tried to handle the flooded error and followed this example](https://github.com/alexander-akhmetov/python-telegram/blob/91d577e75f7dbfe022fe9085f2a7bacef6712ee2/examples/send_message.py)

I tested it by looping the send_message function 300 times. I could sent 250 messages but than I got this error: "Error: 429 : Too Many Requests: retry after 19"
But still all the time result.error was False.

function calls

Currently there are some functions (get_me(), get_chat(), get_chats(), ...) implemented in client.py, some functions can be called via the call_method() function.
How do you plane to have this in the future? do you want to have all functions implemented?
maybe split up in two py-files: one for functions which can be used for the bot, the other one for normal API functions.
I could give you a hand with this.

Add handler for all update types

Right now it is required to specify update type, but it would be great to subscribe to all updates

The right way to handle errors (esp. flood_wait_ )?

Hi all,

I am trying to fetch messages from a bunch of public channels and eventually start hitting "FLOOD_WAIT_" errors.

Do you mind sharing what is the best way to catch those errors (so that script pauses sending requests)?

Thank you.

Remove time.sleep from AsyncResult

I'm getting system error in Windows 10

Hello!
I used python-telegram library to build Telegram client. When I had launched python script in PowerShell I got pop-up window with error message. Unfortunately I didn't make a screenshot. The message said that I'm trying to launch file dedicated for another operating system and showed the path to the file contained "linux" directory.

get_chats() returns empty chat list

I can run the ping pong example but i can not receive chat ids.

from telegram.client import Telegram

tg = Telegram(
    api_id='0123455',
    api_hash='blablabla',
    phone='00491766822222',  # you can pass 'bot_token' instead
    database_encryption_key='changekey123',
)
tg.login()

    # if this is the first run, library needs to preload all chats
    # otherwise the message will not be sent
result = tg.get_chats()
result.wait()
print(result.update)

This is the result:

{'@type': 'chats', 'chat_ids': [], '@extra': {'request_id': 'd8acbe24880e4385a8a7ce8b79a2bbda'}}

Any idea how to solve this?

Remove if condition in _run_handlers

Hi

The if condition in _run_handlers is creating issues, when I try to test tgvoip example. I modified it as

    def _run_handlers(self, update: Dict[Any, Any]) -> None:
        if update.get('@type') == 'updateNewMessage':
            for handler in self._message_handlers:
                self._workers_queue.put(
                    (handler, update),
                    timeout=self._queue_put_timeout,
                )
        else:
            
            for handler in self._message_handlers:
                self._workers_queue.put(
                    (handler, update),
                    timeout=self._queue_put_timeout,
                )

or we can create another method for add_message_handler like add_call_handlerand append functions to new list like _call_handler. In else condition use it.

If ok, I can create a PR.

sending images

Hey, currently its not possible to send images or? Do you know if its possible with tdlib?

Error loading shared library libssl.so.1.0.0

First I start a shell inside the container:

docker run -i -t --rm -v /tmp/docker-:/tmp/ akhmetov/python-telegram sh

From inside the container, I then cd to the examples directory

cd /app/examples

and call get_me.py

python3 get_me.py <id> <hash> <phone>

But this error occurs:

[FeatureRequest] Add getUserFullInfo() support

In the TDLIB update event, there is only the 'sender_user_id' field and no other user identification. Currently, there is no way to get first and last names using python-telegram.
As far as I know, to get that information the client should use getUserFullInfo() method. Please, add it.

Telegram.login() dont use stdin/stdout

Hi,
I am trying to build a telegram-client with this library, that does not get its inputs from stdin. Unfortunately Telegram.login() asks the confirmation code from the standard input. Is it possible to relay the code in any other matter?
Like one call to start the process of obtaining the code, and a call to another function to verify it. This way it would allow me to forward the request to the UI.
Another thing I noticed is that by using the library I have a lot of output in my stdout. This seems to be some kind of debug mode. Is it possible to run it outside of a debug mode?

Add ability to make blocking calls

_send_data should be able to accept a new optional parameter: block (False by default).

If it's true, the function waits for the result.

Asyncio?

Hi. In tdlib repo, it is mentioned that "The wrapper uses the full power of asyncio" . But is it true?

Check `stop` method

> tg._tdjson.stop()

*** AttributeError: dlsym(0x7fac0dd74cb0, _td_json_client_destroy): symbol not found

how to fix stop method bug

hello how i can fix stop method bug?

Finding database_encryption_key

Hello! I find it strange that I cannot find anything regarding the database_encryption_key.
Where do I get or set that part? The rest is under control but not this part.
In Telegram's doc they say I can leave it empty. But I'm not sure if it's okay with this app.

32-bit version of libs

I am trying to use python-telegram on a Raspberry Pi which has a 32-bit core. I loaded python-telegram using the command:

`python3 -m pip install python-telegram`

When I run the tutorial I get this error:

`lib/python3.6/site-packages/telegram/lib/linux/libtdjson.so: wrong ELF class: ELFCLASS64`

How do I get a 32-bit version of the libs?
