This example sends a JPEG image file to PubNub service, and receive the data from the service and open it as a image.

I used PIL to process images.

• file_pub.py
  • This sends a file
• file_sub.py
  • This receives a file
• file_list.py
  • This lists files stored in the PubNub service

Create the param.sh to register environmental variables for PubNub keys. param.sh is listed in .gitignore file to prevent accidents.

export PUBNUB_PUBKEY=pub-xxxxxx
export PUBNUB_SUBKEY=sub-xxxxxx

Execute param.sh

(venv)$ . param.sh

(venv)$ python file_pub.py

(venv)$ python file_list.py

(venv)$ python file_sub.py

This sample code uses PIL to open JPG data.

This project includes sample codes: pub.py and sub.py

This are based on the official document's sample codes. Please refer the documents for use.
