|
|
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())
|
|
|
|
|
