Python package to access Universa API from python.
This is an under-construction official Python package from Universa to facilitate access to the Java library using Universa's UMI protocol.
pip install universa
You need to have UMI installed somewhere on your system. To run, UMI requires JVM v1.8.* (or newer) to be installed, too.
UMI can be used in one of three modes:
pipe– the UMI instance is dynamically executed in a subprocess, and a pipe is used for communication.
tcp– connect to an already running UMI instance via TCP socket.
unix– connect to an already running UMI instance via Unix socket.
By default it expects an
umi binary to be installed an reachable via the shell
$PATH, and will invoke it automatically in
universa.transport.setupUMI method if you need to switch the connection method to some other.
#!/usr/bin/env python3 from universa.transport import transport from universa.types import PrivateKey, Contract, RevokePermission if __name__ == '__main__': # The next line is not necessary if umi is reachable via the $PATH # transport.setupUMI('pipe', '/usr/local/bin/umi') # To connect to an already running UMI instance you may use one of this modes: # transport.setupUMI('tcp', host='127.0.0.1', port=12345) # IPv6 is also ok # transport.setupUMI('unix', path='/path-to-the-socket') print(transport.version) private_key = PrivateKey(size=2048) contract = Contract() short_address = private_key.public_key.short_address owner_role = contract.set_owner_addresses(short_address) revoke_permission = RevokePermission(owner_role) contract.add_permission(revoke_permission)
