Problem running Heroku's Facebook app tutorial with Python

Question

I am testing Heroku's ability to write a Facebook app with Python. I'm having a problem running the basic tutorial. It seemed like this question was worth asking on StackOverflow in case there's an answer that helps other people who run into the exact same problem.

I followed the instructions on heroku's facebook development page (http://devcenter.heroku.com/articles/facebook). Deploying to Heroku worked fine.

However, running the app locally does not. When I follow the instructions and bring up

http://localhost:5000

I get to the Facebook Login screen. But when I click Log In on that screen, I get:

SSL connection error Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have. Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error.

and the console output is

When I try it in Safari, the address bar shows the following very long URL:

https://localhost:5000/?code=AQBPWpkbRdL2bt7KER0fcUS9ZnheXiGApkaF5MXbNgyIJqzw46SGve1iVyLIx1sDltNh0PkXPDdxhjAxoa1YED1cpcaflCXCkqzO27A-rhgjBpXwWUClpGRpRmDD2eIXcOyIczo_qGf45tbpvDZO5hFa0gmUeSHri4vY3bqw-5jBjZRoZfEB7pI8cLPOIsnNICI#_=_

Safari compains that it can't establish a secure connection.

This is running on OS X 10.6.8.

Answer 1

This is because https is not enabled locally on your machine, you could enable this or you could alternatively run without the SSL on your localhost. To do this you would edit the function to look something like:

def get_home():
    return 'http://' + request.host + '/'
