SSLError in Requests when packaging as OS X .app

Question

I\'m developing an application for OS X. The application involves communicating with a server through python-requests, using a secure connection.

I am able to run the p

Requests uses a bundle of ceritificates to verify a servers identity. This bundle is kept (it has to be) in an independent file. Normally requests ships with its own bundle, but if packaged into a single file the bundle is lost. You can ship a new bundle alongside your app or let requests use the systemwide certificate. (I don't know, where OS X keeps this file, but on my linux box its /etc/ssl/certs/ca-certificates.crt)

To see, where requests expects the file you can do this:

import requests
print(requests.certs.where())

To change the location, where requests looks for the bundle you can pass the verify-parameter with a string value:

import requests
requests.get("https://httpbin.org/", verify="path/to/your/bundle")

If you don't want to pass the parameter every time, create a session and configure it to use your bundle:

import requests
s = requests.Session()
s.verify = "path/to/your/bundle"
s.get("https://httpbin.org")
