# pylint: disable=too-many-lines,no-self-use,unused-variable,unused-argument
"""
This is not what you run to run the Bitmessage API. Instead, enable the API
( https://bitmessage.org/wiki/API ) and optionally enable daemon mode
( https://bitmessage.org/wiki/Daemon ) then run bitmessagemain.py.
This is not what you run to start the Bitmessage API.
Instead, `enable the API <https://bitmessage.org/wiki/API>`_
and optionally `enable daemon mode <https://bitmessage.org/wiki/Daemon>`_
then run the PyBitmessage.
The PyBitmessage API is provided either as
`XML-RPC <http://xmlrpc.scripting.com/spec.html>`_ or
`JSON-RPC <https://www.jsonrpc.org/specification>`_ like in bitcoin.
It's selected according to 'apivariant' setting in config file.
Special value ``apivariant=legacy`` is to mimic the old pre 0.6.3
behaviour when any results are returned as strings of json.
.. list-table:: All config settings related to API:
:header-rows: 0
* - apienabled = true
- if 'false' the `singleAPI` wont start
* - apiinterface = 127.0.0.1
- this is the recommended default
* - apiport = 8442
- the API listens apiinterface:apiport if apiport is not used,
random in range (32767, 65535) otherwice
* - apivariant = xml
- current default for backward compatibility, 'json' is recommended
* - apiusername = username
- set the username
* - apipassword = password
- and the password
* - apinotifypath =
- not really the API setting, this sets a path for the executable to be ran
when certain internal event happens
To use the API concider such simple example:
.. code-block:: python
import jsonrpclib
from pybitmessage import bmconfigparser, helper_startup
helper_startup.loadConfig() # find and load local config file
conf = bmconfigparser.BMConfigParser()
api_uri = "http://%s:%s@127.0.0.1:8442/" % (
conf.safeGet('bitmessagesettings', 'apiusername'),
conf.safeGet('bitmessagesettings', 'apipassword')
)
api = jsonrpclib.ServerProxy(api_uri)
print(api.clientStatus())
For further examples please reference `.tests.test_api`.
