How to set facebook authentication keys depending on environment?

阅读更多关于 How to set facebook authentication keys depending on environment?

I have a rails app which uses omniauth to authenticate visitors via facebook. When you register an app with facebook, you have to register a callback url which they will redirect to once they have completed their authentication process. Since my production site is hosted on a different server than my development environment, I need to register 2 different urls with Facebook. I've done this by registering two apps, a live one and a dev version. Now of course I have two app_ids and two app_secrets which my Rails application needs to use. How do I set OmniAuth to use one set of keys in the

Rails omniauth - twitter asking for app authorization each time user logs in

阅读更多关于 Rails omniauth - twitter asking for app authorization each time user logs in

问题 In Railscast: http://railscasts.com/episodes/241-simple-omniauth Ryan uses omniauth for logins. In the video when he clicks on the login button the first time Twitter asks the user if they would like to authorize Ryan's app. The second time the login button is clicked it automatically logs the user in. In my application, the user is forced to authorize my app each time. If the user is logged into twitter and has already authorized the app, then shouldn't it "just work"? EDIT: my app currently

OmniAuth before_filter for requiring login

阅读更多关于 OmniAuth before_filter for requiring login

is it possible using OmniAuth to require login before certain actions? I remember from a railscast that Devise has a before_filter, but does OmniAuth? You can add a before_filter : class ApplicationController < ActionController::Base before_filter :authenticate def authenticate redirect_to :login unless User.find_by_provider_and_uid(auth["provider"], auth["uid"]) end ... end Presuming: 1. You have defined a login page with link(s) like : <%= link_to "Sign in with Facebook", "/auth/facebook" %> See also RailsCasts tagged with authentication 来源： https://stackoverflow.com/questions/4477745

How to use omniauth to make authenticated calls to services?

阅读更多关于 How to use omniauth to make authenticated calls to services?

I've received a token / secret from a service using OmniAuth and can store it for users, but I'm stuck as to how to actually use these to call a service. The closest thing I've seen to this question is here but the way he's solved that there doesn't feel right. I feel like OmniAuth likely does this all for you if you know what you're doing. Netflix has a pretty involved auth process , so I was hoping to skirt all of this by using OmniAuth to abstract me from all of this. Given that I have a token and secret for a user, how to use these in calling a service like Netflix? Many thanks :) Hey, I'm

Display a Twitter feed from a Rails app

阅读更多关于 Display a Twitter feed from a Rails app

问题 I have been able to have a user sign in with Twitter via OmniAuth (I followed Railscast #235-6 and made a simple application). Now I am trying to display the Twitter feed of the logged in user. Can anyone tell me how this is done? How do I initialize Twitter? How do I pass in the username and password of the logged in user? I am new to Rails so it would be helpful if I knew exactly where to put the code. Thanks 回答1: First, you don't need user credentials to get a Twitter feed if it's public.

问题 I am using Devise with Omniauth to have users sign into my app with Facebook. I used the Railscast tutorials to get it up and running. If a user is already a member of my site authenticating through facebook works fine. The problem comes in when authenticating a new user with facebook. When it goes to create a new user for my User model I get the "users.encrypted_password may not be NULL" error. I can't figure out how to pass over the password to the User model from Facebook information. This

When you use OmniAuth to login to a web app through Facebook, these are the permissions the webapp has: Access my basic information Includes name, profile picture, gender, networks, user ID, list of friends, and any other information I've shared with everyone. Send me email WebApp may email me directly at email@email.com Access my data any time WebApp may access my data when I'm not using the application Whereas when you use the mini_fb gem to link a web app to Facebook, these are the permissions (have to specify this as code otherwise formatting was weird): Access my basic information
