Google OAuth Go Sample Project - Web application

This is a web application that demonstrates how to do Google Oauth to log-in an authenticate users.

Installation

Simply go get github.com/Skarlso/google-oauth-go-sample.

Setup

Google

In order for the Google Authentication to work, you'll need developer credentials which the this application gathers from a file in the root directory called creds.json. The structure of this file should be like this:

{
  "installed": {
    "client_id": "hash.apps.googleusercontent.com",
    "project_id": "random",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://oauth2.googleapis.com/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_secret": "secret",
    "redirect_uris": [
      "http://localhost"
    ]
  }
}

To obtain these credentials, please navigate to this site and follow the procedure to setup a new project: Google Developer Console.

Once you have a new project, you need to create the above credentials. Navigate to the Project Page Credentials section and create an Oauth Client ID. Select Desktop app and you should have your Client ID like the above JSON document.

Dependencies

To gather all the libraries this project uses, simply execute from the root: go get -v ./...

Running

To run it, simply build & run and navigate to http://127.0.0.1:9090/login, nothing else should be required.

go build
./oauth-sample

Login fails

I was testing this per your instructions to get familiar with Oauth.
I get it running with keys, I get the Google screen asking me to use an account.

After I select a Google account to login with, it tries to load 127.0.0.1:9090 but on the server side I see it crashes.

I suspect this error "[sessions] ERROR! securecookie: the value is not valid" makes the session invalid and the database crashes trying to get the session? Any idea on how to fix it?
