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.
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.
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 -dJupyter Notebook will be available on port 3100 (http://localhost:3100).
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 pytonlib import TonlibClient
# downloading mainnet config
ton_config = requests.get('https://newton-blockchain.github.io/global.config.json').json()
# get running event loop
loop = asyncio.get_running_loop()
# init TonlibClient
client = TonlibClient(ls_index=0, # choose LiteServer index to connect
config=ton_config,
keystore='/tmp/ton_keystore',
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 pytonlib import TonlibClient
async def main():
loop = asyncio.get_running_loop()
ton_config = requests.get('https://ton-blockchain.github.io/global.config.json').json()
# init TonlibClient
client = TonlibClient(ls_index=0, # choose LiteServer index to connect
config=ton_config,
keystore='/tmp/ton_keystore',
loop=loop)
# init tonlibjson
await client.init()
# reading masterchain info
masterchain_info = await client.get_masterchain_info()
# closing session
await client.close()

asyncio.run(main())To run tests in asyncio mode use the following command:
PYTHONPATH=./ pytest --asyncio-mode=strict tests/
