AsyncSpaceTrackApi async client
_______________________________
Small async wrapper for "space-track-api" package.
Requirements
------------
- Python >= 3.5.0
- space-track-api > 1.0.0
- aiohttp >= 2.0.7
Installing
__________
::
pip install aio-space-track-api
Getting started
---------------
To retrieve something from Space-Track:
.. code-block:: python
# -*- coding: utf-8 -*-
import asyncio
from pprint import pprint
from aio_space_track_api import AsyncSpaceTrackApi
async def main(loop):
async with AsyncSpaceTrackApi(loop=loop, login='<YOUR_LOGIN>', password='<YOUR_PASSWORD>') as api:
tle_list = await api.tle(EPOCH='>now-3',
NORAD_CAT_ID=(25544, 25541,),
order_by=('EPOCH desc', 'NORAD_CAT_ID',),
predicate=('EPOCH', 'NORAD_CAT_ID', 'TLE_LINE0', 'TLE_LINE1', 'TLE_LINE2',))
pprint(tle_list, indent=2)
if __name__ == '__main__':
loop = asyncio.get_event_loop()
loop.run_until_complete(main(loop))
Create simple proxy Space-Track server:
.. code-block:: python
# -*- coding: utf-8 -*-
from aiohttp import web
from aio_space_track_api import AsyncSpaceTrackApi
async def query(request):
params = {mvk: request.query.getall(mvk) for mvk in request.query.keys()}
result = await app['space_track'].query(**params)
if isinstance(result, (dict, list)):
return web.json_response(result)
elif isinstance(result, str):
return web.Response(text=result)
return web.Response(body=result)
async def start_space_track(app):
app['space_track'] = AsyncSpaceTrackApi(loop=app.loop, login='<YOUR_LOGIN>', password='<YOUR_PASSWORD>')
await app['space_track'].login()
async def cleanup_space_track(app):
await app['space_track'].logout()
app['space_track'].session.close()
if __name__ == '__main__':
app = web.Application()
app.on_startup.append(start_space_track)
app.on_cleanup.append(cleanup_space_track)
app.router.add_get('/', query)
web.run_app(app, port=8080)
Retrieve with "httpie" <https://github.com/jakubroztocil/httpie> package::
$ http 'http://localhost:8080/?EPOCH=>now-2&NORAD_CAT_ID=25544&order_by=EPOCH%20desc&order_by=NORAD_CAT_ID&predicate=NORAD_CAT_ID&predicate=EPOCH&NORAD_CAT_ID=25541&predicate=TLE_LINE0&predicate=TLE_LINE1&predicate=TLE_LINE2'
