Clojure - oauth credentials and signature - oauth

Iam trying to implement oauth (clj-oauth https://github.com/mattrepl/clj-oauth) for use with the flickr API.
I already have the access-token and just need the credentials but here I get stuck.
My code looks like this:
(def credentials (oauth/credentials consumer
(:oauth_token access-token-response)
(:oauth_token_secret access-token-response)
:GET
"http://api.flickr.com/services/rest/..."
{:status "??")))
The url I need to call is:
http://api.flickr.com/services/rest/?method=flickr.photosets.getList&api_key=3c2cfaf22751d55db9e0a4d02be254d7&user_id=92219076%40N07&format=json&nojsoncallback=1&auth_token=72987632743515342-8c99972fdac0b886&api_sig=cca1c874268986779d229f72ab65ee5a
But the example above is not clear for me and what is this :status?
Will the :status be translated to /?status="..." ?
And the second question is... where can I find the api_sig?
Should it be generated by oauth/make-consumer ?
Thanks for your help!

For the first part, have a look at my answer to a similar question.
api_sig is part of Flickr's old, now deprecated non-oauth authentication.

graphql_devise for authentication in Rails/Graphql/Apollo/React. "field requires authentication" error

I have a project where I am setting up a Rails API with Graphql and React/Apollo. I've purpled all the google links looking for the best authentication solution, but it seems I haven't been able to find a clear answer.
I settled on using the graphql_devise gem, which leverages devise & devise_token_auth. I would have preferred to find a JWT solution, but just couldn't. (If you have any obvious suggestions please tell me!)
First I mounted a separate auth route, but ran into problems with multiple endpoints when I was setting up ApolloClient. I couldn't figure out how to direct auth related requests to my auth endpoint, while letting the rest go through to my graphql one. (If figuring this out is the easiest solution, please tell me!) Instead, I mounted the auth routes in my own schema, as instructed by the docs:
class MyApiSchema < GraphQL::Schema
use GraphqlDevise::SchemaPlugin.new(
query: Types::QueryType,
mutation: Types::MutationType,
resource_loaders: [
GraphqlDevise::ResourceLoader.new('User', only: [:login, :logout])
]
)
mutation(Types::MutationType)
query(Types::QueryType)
And edited the execute line in graphql_controller.rb:
result = MyApiSchema.execute(query, variables: variables, context: graphql_context(:user), operation_name: operation_name)
At this point, running a test query in postman is successful. I can access the graphql route with a userLogin mutation without any headers set, and get a successful response with client, uid & token. Authentication of my other queries also works—success with headers, denied without.
But when I try to perform the same queries using useQuery in react, it doesn't work. In the Apollo Client Developer Tools plugin in Chrome, it doesn't work either, returning only [Object object]. By looking at the request in my Network tab, I can see that this is the result of the same error: "photo field requires authentication".
When I pry into the rails server, I can see that the headers are being received. I can even authenticate the user manually in my graphql_controller before the execute method is called, so I don't think that it is a CORS issue. I have set up the rack-cors gem in Rails to expose the required headers.
When I drill into the code, it seems that the graphql_devise method set_current_resource is failing to return my user. This seems to stem from the devise method set_user_by_token, but I have not been able to figure out why it is failing.
If anyone has any experience with implementing this gem & stack, I would very much appreciate your input! If you have a better way of approaching authentication, I'd love to know what your strategy is. If you can help me solve this ... field requires authentication error, I will love you forever.
Apologies if I've provided too much/too little info, or if my question is too vague. Please let me know if there's something specific I should know to ask/show in my code. Hope you can help! Thanks.
I've managed to find the issue, and I thought I'd explain.
Having traced the problem to the set_user_by_token method in the devise_token_auth gem, I bundle open devise_token_auth'd, and put a byebug inside. This revealed that #token.token was not being extracted correctly from the headers.
The problem was that my header access-token was somehow being converted to accessToken, so when devise tried to set the token info from the request headers using this key, it returned nil.
I do not know why or where this conversion takes place. I suspect it originates from Apollo/React rather than Rails, since the headers on my postman query were not altered. In react, when I set the headers they are set with access-token, as below, but it seems that at some point in the life of my request they are changed.
How I have set the headers in React:
const client = new ApolloClient({
cache,
link: new HttpLink({
uri: 'http://localhost:3000/graphql',
headers: {
accessToken: localStorage.getItem('access-token'),
client: localStorage.getItem('client'),
uid: localStorage.getItem('uid')
},
}),
});
The keys that devise_token_auth uses to select the headers from the request can be changed in the initializers/devise_token_auth.rb file.
I edited them as follows:
config.headers_names = {:'access-token' => 'accessToken',
:'client' => 'client',
:'expiry' => 'expiry',
:'uid' => 'uid',
:'token-type' => 'token-type' }
This means that my front-end is now working smoothly, and I can perform queries/mutations with authentication. However, now in my postman queries I have to change the header to accessToken if I want them to work.
It would be great to know exactly at what point my header from React is changed to camelCase, but for now, it's working. Hope this helps if anyone goes through the same frustrations!

What is Facebook callback_url and how to use it in rails?

I am using the Facebook Graph API in my rails projects, no matter I use oauth2 gem or koala, It need callback_url
Oauth2
token = client.auth_code.get_token('code_value', :redirect_uri => 'http://localhost:8080/oauth/callback')
Koala
#oauth = Koala::Facebook::OAuth.new(app_id, app_secret, callback_url)
I try to use http://localhost:3000/callback in my project, but it's not working.
Should I develop a routes for that?
like: get 'callback' => 'oauth#callback'?
What should I write in the callback method in OauthController, what does it use for? Thanks
Yes, you should.
Basically, OAuth uses callback data to provide tokens for authenticating users.
For example
user clicks on "sign in" (or whatever) link and your app redirects they to the OAuth provider (or open it in the iframe).
user permits to your app to use they profile details
OAuth provider send callback to your app with unique code
app uses that code to get secure access token for API communications
That's just a basic example.
In your case you need to implement controller that will parse callback data.
Here is the code example
#oauth = Koala::Facebook::OAuth.new(api_key, app_secret, callback_url)
=> #<Koala::Facebook::OAuth:0x007fc919d014e0 #app_id=1234567890, #app_secret="FaKeAppSecretKey", #oauth_callback_url="http://localhost:3000/callback">
#oauth.url_for_oauth_code
=> "https://www.facebook.com/dialog/oauth?client_id=893637180663238&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fcallback"
And when you go to https://www.facebook.com/dialog/oauth?client_id=893637180663238&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fcallback FB will redirect you to
http://localhost:3000/callback?code=CODE_FROM_CALLBACK
Then you should use implement controller that uses code to get access token
access_token = #oauth.get_access_token(params[:code])
=> "ACCESS_TOKEN"
#graph = Koala::Facebook::API.new(access_token)
=> #<Koala::Facebook::API:0x007fc91a903ae0 #access_token="ACCESS_TOKEN", #app_secret=nil>
profile = #graph.get_object("me")
=> {"id"=>"4492344324865", "email"=>"my_fake_email_address#gmail.com", "first_name"=>"Roman", "gender"=>"male", "last_name"=>"Sotnikov", "link"=>"https://www.facebook.com/app_scoped_user_id/4492344324865/", "locale"=>"en_US", "name"=>"Roman Sotnikov", "timezone"=>6, "updated_time"=>"2015-05-18T05:19:54+0000", "verified"=>true}
Please check https://github.com/arsduo/koala/wiki/OAuth for additional info.
Callback Url is yours applications url -- a GET route -- you want the third party application to redirect to, after its done its work.
So in your routes.rb file simply create a get route
get 'facebook_graph_callback', to: 'controller_name#action'
#A get route which is connected to a controller action
Usually the third party will give you some sort of information back. Quite often its some sort of code. In your controller action you can use find them in params hash.

Get activities of a Google plus user using Rails

I am trying to read and display activities of a G+ user. Using Google oauth2 I could able to recieve the access_token of a user after authorization has completed.
I use google_plus gem to make calls to G+, i could able to recieve user information using below code
#person = GooglePlus::Person.get("user_id_goes_here", :key => "google_api_key_here")
but when i try to get the activities using below
activity = GooglePlus::Activity.get("user_id_goes_here")
i could able to see the below error,
i tried searching the web for a solution, and some suggest that the api call limit exceeded. (10,000 hits/day is default). But i am sure i have used this only with 20-30 calls today.
Any suggestions for this issue is appreciated.
FYI : I have just added config code for google_oauth2 in /config/initializers/omniauth.rb file as below provider :google_oauth2,Rails.application.config.client_id , Rails.application.config.client_secret
Note: Below is the screenshot when i try to authenticate with Oauth2.
I hope this doesnot include Google plus scope, to make it i know i should add {:scope => "REQUIRED_URL_HERE_GOOGLE_PLUS_RELATED"} in omniauth.rb. But not sure what url should i give in there.
Thanks,
Balan
The Google_Plus gem requires you to pass your app key with every request. You can either do this inline:
GooglePlus::Activity.get("user_id_goes_here", key: "api_key_goes_here")
Or set up a global variable in an initializer
GooglePlus.api_key = 'api_key_goes_here'
The examples in the gem spec assume you have included a global variable, and hence don't show the key: strings. This may be what is causing you problems?
In answer to your second question, you will need to specify a scope with your oauth requests. A list of scopes is given here https://developers.google.com/gdata/faq#AuthScopes, but it is worth noting that the url format seems to have changed from that published. Try https://www.googleapis.com/auth/xxxxx instead, where xxx is the service you require.
I could able to find a solution for my question..
1) Used {:scope => "https://www.googleapis.com/auth/plus.me"} in /config/initializers/omniauth.rb file
2) Used the code
activities = GooglePlus::Activity.for_person("user_id", :key => "GOOGLE_API_KEY").items
Hope someone will find this useful.

Ruby-OpenID: Requiring email-address from OpenID provider

I'm playing with the authlogic-example-app and I'm failing to get the email address from the OpenID provider (in my case: Google and Yahoo) when I register a user, resp. I get an empty response instead of an email address (check the comments in code below).
This is how my user model looks like (everything else looks like the "with_openid"-branch of the authlogic-example-app mentioned above). Besides the missing 'email', the openid-authentication-process works as expected:
class User < ActiveRecord::Base
acts_as_authentic do |c|
# not needed because I use OpenID
c.validate_login_field = false
# avoid failed validation before OpenID request
c.validate_email_field = false
# this one sets 'openid.sreg.required=email'
c.required_fields = [:email]
end
private
# overwriting the existing method in '/lib/authlogic_openid/acts_as_authentic.rb'
def map_openid_registration(registration)
# this is my problem: 'registration' is an empty hash
self.email ||= registration[:email] if respond_to?(:email) && !registration[:email].blank?
end
end
Any idea how to solve this? Has anyone here done this before using authlogic? Or even better: Do you have a working example?
Update: I checked the Google Account Authentication API and compared the request submitted by authlogic (using ruby-openid-gem and openid-authentication-plugin) with the example requests on the Google Account Authentication API docs:
Example request to authenticate and fetch email address by Google:
https://www.google.com/accounts/o8/ud
?openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0
&openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select
&openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select
&openid.return_to=http%3A%2F%2Fwww.example.com%2Fcheckauth

&openid.ns.ax=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0
&openid.ns.sreg=http%3A%2F%2Fopenid.net%2Fextensions%2Fsreg%2F1.1
&openid.realm=http%3A%2F%2Flocalhost%3A3000%2F
&openid.return_to=http%3A%2F%2Flocalhost%3A3000%2Faccount%3Ffor_model%3D1%26_method%3Dpost%26open_id_complete%3D1
&openid.sreg.required=email
While debugging the whole setup, I've found out that the openid-authentication-plugin never receives an email in the response it receives from the openid provider, this at least explains why the registration hash in my user-model is empty...
UPDATE: If you're playing around with authlogic and openid, don't forget to check out the latest railscast on this subject!
As nobody could help me, I helped myself. :-)
The short answer to my question is:
c.required_fields = [:email,"http://axschema.org/contact/email"]
Using this line, the application requests the email-address using sreg and ax (request-type supported by Google).
You can find a more detailed answer and a working implementation of authlogic-openid with the Javascript OpenID-Selector right here:
http://github.com/vazqujav/authlogic_openid_selector_example/
While this pointed me in the right direction, what I needed was:
c.openid_required_fields = [:email,"http://axschema.org/contact/email"]
This pulled in the email and set it.
# fetch email by ax
c.openid_required_fields = [
"http://axschema.org/contact/email",
"http://axschema.org/namePerson/first",
"http://axschema.org/namePerson/last",
"http://axschema.org/contact/country/home",
"http://axschema.org/pref/language"
]
This fetches in multiple values as specified # http://code.google.com/apis/accounts/docs/OpenID.html#Parameters
Though I'm still unable to fetch in the country name... name, email, language works perfectly!
Test against an OpenID server you control, since it'll let you debug every part of the OpenID sequence. There are no guarantees that Google's OpenID provider is doing the right thing. Try checking against Verisign's server, since I'm pretty sure that one at least should do the right thing with the openid.sreg.required=email field.
Your code snippet looks right to me.
the thing is i am able to fetch the parameters from the provider but am not able to extract them from the response...
i have used OpenID::AX::FetchResponse.from_success_response(open_id_response)
as the object to hold the response... what method do i use to extract email,nickname,country,etc...

rails in_place_edit: how do I pass an authenticity token?

I am trying to get in place editing working but I am running into this error:
ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken)
I understand that rails now wants to protect against forgery and that I need to pass a form authenticity token but I am not clear on how to do this with the in_place_edit plugin.
This isn't a complete tested answer, but I took a look at the plugin code, and it looks like you could use the :with option to tack the authenticity token onto the end of the request parameters. Something along the lines of:
in_place_editor("my_element", :with => "form.serialize() + '&authenticity_token=#{form_authenticity_token}';")
(I have not tested the above code).
I found a solution. I put the instructions here. Take a look at the part on patching in_place_edit.
