MVC4 Source和VS2010(MVC4 Source and VS2010)

 我没有找到一个很好的方法来做到这一点。 我没有使用:omniauthable ，我正在单独使用OmniAuth和Devise，如Railscast中所见，其中有两个表users和authentications 。 这有点hacky只适用于Facebook。 
 
 基本上，通过SSL或类似的方式将您的access_token从iPhone发送到服务器。 您必须首先检查OmniAuth，如果您被授予访问权限，那么您可以通过以下方式手动创建与OmniAuth的会话： 
 
 尽管如此，我确实得到了一些工作： 
 
FB = OmniAuth::Strategies::Facebook.new("nothing") 

client = ::OAuth2::Client.new("nothing", "nothing", FB.client_options) 

cached_token = "app_id_part|session_id_part|token_part" # or maybe you sent it from the iPhone
access_token = ::OAuth2::AccessToken.new(client, cached_token)  

FB.instance_variable_set("@access_token", access_token) 

FB.auth_hash 
# You will either get a hash or get this error:
# OAuth2::AccessDenied: Received HTTP 401 during request.
 
 之后，您可以通过Authentications表查找查找用户所需的用户信息： 
 
@user = Authentication.where(:uid => FB.auth_hash["uid"], :provider => "facebook").first.user
 
 现在我们创建一个会话： 
 
sign_in_and_redirect(:user, @user)

# or, perhaps

sign_in(@user, :bypass => true)

I have not found a good way of doing this. I am not using :omniauthable either, I'm using OmniAuth and Devise separately as seen in the Railscast episode where there are two tables users and authentications. It's kinda hacky and only works for Facebook.
 
Basically, send your access_token from the iPhone to the server over SSL, or something similar. You have to check with OmniAuth first and if you are granted access, then you can manually create a session with OmniAuth by going something like:
 
I did get something to work by doing this though:
 
FB = OmniAuth::Strategies::Facebook.new("nothing") 

client = ::OAuth2::Client.new("nothing", "nothing", FB.client_options) 

cached_token = "app_id_part|session_id_part|token_part" # or maybe you sent it from the iPhone
access_token = ::OAuth2::AccessToken.new(client, cached_token)  

FB.instance_variable_set("@access_token", access_token) 

FB.auth_hash 
# You will either get a hash or get this error:
# OAuth2::AccessDenied: Received HTTP 401 during request.
 
After that you lookup the user info you need to find the user via your Authentications table:
 
@user = Authentication.where(:uid => FB.auth_hash["uid"], :provider => "facebook").first.user
 
Now we create a session:
 
sign_in_and_redirect(:user, @user)

# or, perhaps

sign_in(@user, :bypass => true)
