如何将CURL命令转换为对OAuth令牌的Rails POST请求？

Question

I am a web-development student and am trying to work with the Instagram API . I have never had to deal with OAuth before.

So far I can get the code from the user authorizing me to use their Instagram credentials but the POST request to get the actual token eludes me. I am trying to use Typhoeus for server side API requests but where I get hung up is in translating curl commands into usable rails controller script.

The Instagram API recommends the following curl command:

curl \-F 'client_id=CLIENT-ID' \
-F 'client_secret=CLIENT-SECRET' \
-F 'grant_type=authorization_code' \
-F 'redirect_uri=YOUR-REDIRECT-URI' \
-F 'code=CODE' \https://api.instagram.com/oauth/access_token

and here is my attempt at a Typhoeus POST request:

request = Typhoeus::Request.new(
  "https://api.instagram.com/oauth/access_token",
  method: :post,
  :body => {:client_id => CLIENT_ID,
              :client_secret => CLIENT_SECRET, 
              :grant_type => "authorization_code", 
              :redirect_uri => CALLBACK_URL, 
              :code => code}
  )
@results = JSON.parse((request.run).body)

And I get the following error when I try and log @results:

{"code"=>400, "error_type"=>"OAuthException", "error_message"=>"You must provide a client_id"}

I have all the info that the API needs, I just don't know how to arrange it correctly... And yes, all of the constants are defined. Any help appreciated!

Answer 1

I recommend using the instagram-ruby-gem to make requests to the Instagram API. You'll find it much easier than using Typhoeus.

Answer 2

Somehow I solved my own question. The above Typhoeus script works just fine, with lots of JSON love for everyone.

I think I might have been having obscure session issues with my rails server when @results kept coming back as nil.

I wish I had a more specific answer as to why this wasn't working earlier, but I'll keep my nose to the ground as I move forward and hopefully have a more satisfying conclusion.

Answer 3

I had the same problem in powershell finally, I put the client_id and code in the query string also. then it works. I mean something like this:

" https://api.instagram.com/oauth/access_token?client_id=CLIENT_ID&code=code "
