Ruby google_drive gem oAuth2 save
So, before the update, there was an easy way to log into Google Drive and manipulate your google docs - with ruby.
Before you were able to log into your google drive with this.
require 'google_drive'
$session = GoogleDrive.login("email@gmail.com", "password")
But now you get a warning message:
WARNING: GoogleDrive.login is deprecated and will be removed in the next version. Use GoogleDrive.login_with_oauth instead.
So I went to the git hub page to see how Google wants us to use their services in high-level languages and find out they want us to use oAuth2. Like this.
require 'google/api_client'
require 'google_drive'
client = Google::APIClient.new(
:application_name => 'Example Ruby application',
:application_version => '1.0.0'
)
auth = client.authorization
auth.client_id = "YOUR CLIENT ID"
auth.client_secret = "YOUR CLIENT SECRET"
auth.scope =
"https://www.googleapis.com/auth/drive " +
"https://spreadsheets.google.com/feeds/"
auth.redirect_uri = "urn:ietf:wg:oauth:2.0:oob"
print("1. Open this page:\n%s\n\n" % auth.authorization_uri)
print("2. Enter the authorization code shown in the page: ")
auth.code = $stdin.gets.chomp
auth.fetch_access_token!
access_token = auth.access_token
$session = GoogleDrive.login_with_oauth(access_token)
This is ok and everything except I can't save the auth variable. I would like to write this into a script, so I don't have to google to get a new access_token.
So I tried to get the access_token and add it to the script like so.
require 'google/api_client'
require 'google_drive'
client = Google::APIClient.new
access_token = "TokenFromGoogleHardCoded"
$session = GoogleDrive.login_with_oauth(access_token)
# $session doesn't connect
I am not sure if I am attacking this issue in the correct manor. I would like to keep the complete auth variable and hardcode in my scripts.

I figured out this mess.
auth.scope =
"https://www.googleapis.com/auth/drive " +
"https://spreadsheets.google.com/feeds/"
There is no url in auth.scope. LINK from github
auth.scope =
"https://docs.google.com/feeds/" +
"https://www.googleapis.com/auth/drive " +
"https://spreadsheets.google.com/feeds/"
You can reuse your access_token, but you need to get it first. WARNING: auth.access_token only comes up for an hour. If you need another one, you need to call auth.refresh! This will give you another access_token.
require 'google/api_client'
require 'google_drive'
client = Google::APIClient.new(
:application_name => 'Example Ruby application',
:application_version => '1.0.0'
)
auth = client.authorization
auth.client_id = "YOUR CLIENT ID"
auth.client_secret = "YOUR CLIENT SECRET"
auth.scope =
"https://www.googleapis.com/auth/drive " +
"https://spreadsheets.google.com/feeds/"
auth.redirect_uri = "urn:ietf:wg:oauth:2.0:oob"
print("1. Open this page:\n%s\n\n" % auth.authorization_uri)
print("2. Enter the authorization code shown in the page: ")
auth.code = $stdin.gets.chomp
auth.fetch_access_token!
access_token = auth.access_token
system'clear'
print "Save your access token\n\n"
print access_token
print "\nSave your refresh token\n\n"
print auth.refresh_token
This piece of code should print your access_token / refresh_token to the console. You can now hard code your application.
require "google/api_client"
require "google_driver"
client = Google::APIClient.new(
:application_name => 'Example Ruby application',
:application_version => '1.0.0'
)
auth = client.authorization
auth.client_id = "Your Client ID"
auth.client_secret = "Your client secret"
access_token = "token you saved from the terminal"
session = GoogleDrive.login_with_oauth(access_token)
for file in session.files
p file.title
end
And over time your "access_token" will expire. At this point, you need to "update" it. You can call to see if your access_current has expired by calling
auth.expires_at
In this example, you can get a new access token.
require 'google/api_client'
require 'google_drive'
$client_id = "YOUR CLIENT ID"
$client_secret = "YOUR CLIENT SECRET"
$refresh_token = "SAVED REFRESH TOKEN"
client = Google::APIClient.new(:application_name => 'Example Ruby application', :application_version => '1.0.0')
auth = client.authorization
auth.client_id = $client_id
auth.client_secret = $client_secret
auth.scope = "https://docs.google.com/feeds/" + "https://www.googleapis.com/auth/drive " + "https://spreadsheets.google.com/feeds/"
auth.redirect_uri = "urn:ietf:wg:oauth:2.0:oob"
auth.refresh_token = $refresh_token
#here the magic sauce
auth.refresh!
#as you can see above auth.access_token wasn't passed a value
# but if you call it now you'll see you have a new access_token
auth.access_token
=> new token from server

You may find it easier to use service accounts as described here:

While Duck1337's answer will work, you don't need to call auth.refresh! with google_drive 1.0. *.
All you have to do is save the refresh_token from the moment you provided the authorization code in the first instance, and then always pass that down before the auth.fetch_access_token call! and the tokens will be automatically renewed.
Below I am using login. I use environment variables rather than code constants, so I can add them to Heroku Config Vars and also keep sensitive data from the code.
client = Google::APIClient.new
auth = client.authorization
auth.client_id = ENV['GOOGLE_CLIENT_ID']
auth.client_secret = ENV['GOOGLE_CLIENT_SECRET']
auth.scope = [
"https://www.googleapis.com/auth/drive",
"https://spreadsheets.google.com/feeds/"
]
auth.redirect_uri = "urn:ietf:wg:oauth:2.0:oob"
if ENV['GOOGLE_REFRESH_TOKEN'] == "0" # Always start with 0 in your .env file, e.g. GOOGLE_REFRESH_TOKEN = 0
puts("1. Open this page:\n%s\n\n" % auth.authorization_uri)
puts("2. Enter the authorization code shown in the page: ")
auth.code = $stdin.gets.chomp
end if
auth.refresh_token = ENV['GOOGLE_REFRESH_TOKEN'] #this will be 0 the first time around, but that OK
auth.fetch_access_token!
if ENV['GOOGLE_REFRESH_TOKEN'] == "0"
puts("3. Save this refresh token:\n%s\n\n" % auth.refresh_token) # you can now replace the 0 in your .env file with this token, so it'll be used permanently. You can also add this to the Heroku Config Vars.
ENV['GOOGLE_REFRESH_TOKEN'] = auth.refresh_token #we'll set it here, so it works without having to alter the .env file for this call
end if
GoogleDrive.login_with_oauth(auth.access_token)
