tonkeeper / pytonapi Goto Github PK

Hello!

I've discovered a minor bug: the error content in case of json.JSONDecodeError (line 73) is being returned in a set format instead of a dictionary.

This is causing an AttributeError here

pytonapi.tonapi.methods.accounts.AccountsMethod is missing the method get_jetton_balance(account_id, jetton_id) corresponding to the /v2/accounts/{account_id}/jettons/{jetton_id} API endpoint.
There is only the method get_jettons_balances(account_id) that fetches balances for all Jettons but no method to fetch the balance for a particular Jetton

Hi!

I try to get the raw account state using liteserver method as follows:

from pytonapi import AsyncTonapi

client = AsyncTonapi(api_key="<API_KEY>")

account_address = "EQCqFPpSLtcstURtrXLRCv9wyjfrw7_44_nwvD8JiSmSjbUI"

state = await client.liteserver.get_account_state(account_address)

And I get the following error:

---------------------------------------------------------------------------
ValidationError                           Traceback (most recent call last)

    339 values, fields_set, validation_error = validate_model(__pydantic_self__.__class__, data)
    340 if validation_error:

    343     object_setattr(__pydantic_self__, '__dict__', values)

ValidationError: 1 validation error for RawAccountState

  value is not a valid integer (type=type_error.integer)

I'm pretty sure this error stems from int annotation here:

I tried to do the simple HTTP request without Pydantic response parsing like that:

response = await client._get(method=f"v2/liteserver/get_account_state/{account_address}", params={})

and get the following response

{'id': {'workchain': -1,
  'shard': '8000000000000000',
  'seqno': 37496117,
  'root_hash': '01166afa4bcb8b8bc65499ca755f434f0cfc4d13b7e90eb42ed436a831853e45',
  'file_hash': 'fd4620e8510e0d0b657f7edc6e3cc9f505fac97f63f8f79c8d9c9ee4082f5dd0'},
 'shardblk': {'workchain': 0,
  'shard': 'c000000000000000',
  'seqno': 43158333,
  'root_hash': 'bd96247321a94c9d17945286f85a13e296e2a4ce932764a6c95ddd0126e60bc3',

 'shard_proof':
  .....

So response["shardblk"]["shard"] is indeed not an integer, at least not a decimal one.

I would be grateful if someone can help/share the experience with it.

@nessshon I'm also happy to make a PR, but I'm not quite sure how we should fix it.

Sometimes, when I set message listener, I get such an error on incoming transaction. I even have bought Lite payment plan but the issue persists. I set my handler just like in example.

async def set_transaction_handler():
    tonapi = AsyncTonapi(api_key=TONAPI_KEY)

    # Subscribe to transaction events for the specified accounts
    await tonapi.sse.subscribe_to_transactions(
        accounts=ACCOUNTS, handler=handler, args=(tonapi,)
    )

async def handler(event: TransactionEventData, tonapi: AsyncTonapi) -> None:
    """
    Handle SSEvent for transactions.

    :param event: The SSEvent object containing transaction details.
    :param tonapi: An instance of AsyncTonapi for interacting with TON API.
    """
    print("Transaction received")

    trace = await tonapi.traces.get_trace(event.tx_hash)

How to back pending transaction ?

Hello, how can I send a TON to another person using your library?

Quite self-explanatory

1. Add ssl=False to the AsyncTonapiClient class, to the _request(...) method.

async with await session.get(f"{self.__base_url}{method}",
                      params=params, ssl=False
                      ) as response:

2. Write a description that your library only works with python above 3.10

Thanks 👍

Hi! Are there any potential pitfalls with adding the "raw_body" property to the Message class in schemas? Not to make any additional requests to tonapi when raw body is actually needed. As i understand its just one line addition. Could you please add it? Or i can make a pr if you wish.

python version 3.8.19

plz generate your full requirements.txt file sir.

Subscription request on transactions is as follows:
GET https://tonapi.io/v2/sse/accounts/transactions?accounts=UQD0g_SvxCFDL6siKlAbCGuunZY8R7L6imTN0mIaxIGWGVQf&accounts=UQDcJtaekVgLY5kU55mOf1-h3Ulv2h8ZDW2Ff84Q4a5Ek_aA

But TonConsole docs says:

API method GET https://tonapi.io/v2/sse/accounts/transactions?accounts=<list-of-accounts>&operations= takes in a list of account IDs and an optional list of operations.

Hello, I've got an error while using tonapi.sse.subscribe_to_transactions when "HTTP/1.1 502 Bad Gateway" occurs.

My code snippet:

async def handler(event: TransactionEventData, tonapi: AsyncTonapi) -> None:
    pass

async def main() -> None:
    tonapi = AsyncTonapi(api_key=API_KEY, timeout=60)
    await tonapi.sse.subscribe_to_transactions(
        accounts=ACCOUNTS, handler=handler, args=(tonapi,)
    )
    

if __name__ == "__main__":
    asyncio.run(main())

I've also found a possible solution here: https://github.com/encode/httpx/discussions/1856

When calling the send_message function from tonapi.blockchain with the provided data, the transaction_result always returns False, regardless of the actual outcome of the transaction. This behavior is observed whether the transaction was successful or an error occurred.

        query = wallet.create_transfer_message(
            to_addr=destination_address,
            amount=transfer_amount,
            payload=payload,

How can I access the transaction hash created by the send message function?
