Some tips about Proxy in Development Environment

proxy_tips.md

Setting System Wide Proxy for python pip and nodejs npm:

set HTTP_PROXY=http://username:[email protected]:8080
set HTTPS_PROXY=https://username:[email protected]:8080

Proxy credentials can be provided in the url as the following:

format: http://username:password@proxy_address:port
example: http://username:[email protected]:8080

Issues:

• if proxy_password has special characters like % or '@', then it must be url encoded before use
  Example: AbCdEfG%HiJ
  After Encoding: AbCdEfG%25HiJ

  The following URL Encoder can be used: https://www.urlencoder.org/

• During Development on local server like nodejs or flask some tools may fail to reach your local dev server because it routes the requests through Proxy

  • solution (Python Requests):
    1. Add your server url to NO_PROXY env. variable
       set NO_PROXY=localhost:5000
    2. OR trust_env = False check 'requests' documentation
