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.org/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)

init tonlibjson

await client.init()

* Reading blocks info:
```python
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.org/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: 
```bash
PYTHONPATH=./ pytest --asyncio-mode=strict tests/
