Re: [ice-dev] Python ICore update code
|
I forgot to add that the Core as it is could not establish this connection.
Basically, the Core.setHttpService method was being called through the OSGi DS before the Core.start method was being called. The start method initializes the ComponentContext object which is used by the setHttpService method, so the method was throwing a NullPointerException when it went to use the ComponentContext because it hadn’t been set yet.
To fix this, I just added a call to setHttpService at the end of the start method and added a null check for the componentContext in setHttpService. I’m sure there’s a better way to fix this, so I’ll hold of on committing any changes. I didn’t take any time to dig into a better fix.

Everyone,
Here’s the code I was able to put together to let python post updates to a running Core instance.
import json
import requests
import base64
if __name__ == '__main__':
# Set the ICore url for updates
url = 'http://localhost:8080/ice/update'
# It requires the username:password be encoded
s = base64.b64encode('ice:veryice')
# Set up your json map
payload = {'some': 'data'}
# Set up the headers, These have to be here
headers = {'Authorization' : 'Basic ' + s, 'Content-type': 'application/x-www-form-urlencoded', 'Accept': 'text/plain'}
# Start a requests session
session = requests.session()
# Get the ICE update url
session.get(url)
# Post the json message with the given headers
r = session.post(url, json=payload, headers=headers)
print r
# Close the session
session.close()
Jordan, I imagine you should be able to start experimenting with the Peacock IO stuff using this code now.
Best,
Alex
