PyTONLib

This is standalone Python library based on libtonlibjson, the functionality is similar to the ton-http-api with the following restrictions:

• a client can connect to only one LiteServer;
• a client is asyncronious;
• no requests cache.

Installation

From PyPi

Currently, the library works for Windows, Mac and Linux only on Intel CPUs:

• (Windows) Install OpenSSL v1.1.1 for Win64 from here.
• Install Python 3 package: pip3 install pytonlib.

Docker

In this repo Compose file is provided to deploy the example of service with pytonlib:

docker-compose -f docker-compose.jupyter.yaml build
docker-compose -f docker-compose.jupyter.yaml up -d

Jupyter Notebook will be available on port 3100 (http://localhost:3100).

Examples

We recommend to use IPython or Jupyter Notebook for prototyping because they allow to run async code. An example of running async code from script could be found in the end of this section.

• Connecting to the first LiteServer in mainnet config:

import requests
import asyncio
from pathlib import Path

from pytonlib import TonlibClient


# downloading mainnet config
ton_config = requests.get('https://ton-blockchain.github.io/global.config.json').json()

# get running event loop
loop = asyncio.get_running_loop()

# create keystore directory for tonlib
keystore_dir = '/tmp/ton_keystore'
Path(keystore_dir).mkdir(parents=True, exist_ok=True)

# init TonlibClient
client = TonlibClient(ls_index=0, # choose LiteServer index to connect
                      config=ton_config,
                      keystore=keystore_dir,
                      loop=loop)

# init tonlibjson
await client.init()

• Reading blocks info:

masterchain_info = await client.get_masterchain_info()
block_header = await client.get_block_header(**masterchain_info['last'])
shards = await client.get_shards(master_seqno=masterchain_info['last']['seqno'])

• Reading Block Transactions for masterchain block:

masterchain_info = await client.get_masterchain_info()
txs = await client.get_block_transactions(**masterchain_info['last'], count=10)

• Running async code from script:

import requests
import asyncio
from pathlib import Path

from pytonlib import TonlibClient


async def main():
    loop = asyncio.get_running_loop()
    ton_config = requests.get('https://ton-blockchain.github.io/global.config.json').json()

    # create keystore directory for tonlib
    keystore_dir = '/tmp/ton_keystore'
    Path(keystore_dir).mkdir(parents=True, exist_ok=True)
    
    # init TonlibClient
    client = TonlibClient(ls_index=0, # choose LiteServer index to connect
                          config=ton_config,
                          keystore=keystore_dir,
                          loop=loop)
    
    # init tonlibjson
    await client.init()
    
    # reading masterchain info
    masterchain_info = await client.get_masterchain_info()

    # closing session
    await client.close()


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

Running tests

To run tests in asyncio mode use the following command:

PYTHONPATH=./ pytest --asyncio-mode=strict tests/
