copied!<p>So I wasn't able to get fb_graph to work properly - I am still a noob having been a Ruby On Rails developer for a total of about 8-10 weeks, and therefore don't have an instinct for what must be obvious problems to other folks.</p> <p>However I found this great little blog post which outlines a simple facebook client and shows clearly how it all plugs together. I found an issue with it picking up the me/picture object as Facebook returns an http302 not http200 but that was easily worked around with the help of the author. Check it out: <a href="http://bnerd.de/misc/ruby-write-basic-client-for-facebook-graph-api/" rel="nofollow">http://bnerd.de/misc/ruby-write-basic-client-for-facebook-graph-api/</a></p> <p>I am now using Omniauth for the simplicity of the login/signup interaction based on this walkthrough here: blog.railsrumble.com/blog/2010/10/08/intridea-omniauth and with the token I get from that I am using this simple FBClient from the bnerd reference above to access the Graph API. Hope what I found helps others.</p> <p>...here's my version of bnerd's code and it worked for me:</p> <pre><code> class FBClient def initialize(app, access_token = nil) @app = app @access_token = access_token end # request permission(s) from user def request(perms) #create a random verifier to identify user on fb callback verifier = (0...10).map{65.+(rand(25)).chr}.join uri = "https://graph.facebook.com/oauth/authorize?client_id=#{@app.app_id}&redirect_uri=#{@app.connect_url}?verifier=#{verifier}&scope=#{perms}" request = { :verifier => verifier, :uri => uri } return request end def connect(code, verifier) uri = URI.parse("https://graph.facebook.com/oauth/access_token?client_id=#{@app.app_id}&redirect_uri=#{@app.connect_url}?verifier=#{verifier}&client_secret=#{@app.secret}&code=#{CGI::escape(code)}") http = Net::HTTP.new(uri.host, uri.port) http.use_ssl = true request = Net::HTTP::Get.new(uri.path + "?" + uri.query) response = http.request(request) data = response.body return data.split("=")[1] end # get, post def get(path, params = nil) uri = URI.parse("https://graph.facebook.com/" + path) http = Net::HTTP.new(uri.host, uri.port) http.use_ssl = true if params.nil? params = Hash.new end if params["access_token"].nil? params["access_token"] = @access_token unless @access_token.nil? end request = Net::HTTP::Get.new(uri.path) request.set_form_data( params ) request = Net::HTTP::Get.new(uri.path + "?" + request.body) return response = http.request(request) end def post(path, params = nil) uri = URI.parse("https://graph.facebook.com/" + path) http = Net::HTTP.new(uri.host, uri.port) http.use_ssl = true if params.nil? params = Hash.new end if params[:access_token].nil? params[:access_token] = @access_token unless @access_token.nil? end request = Net::HTTP::Post.new(uri.path) request.set_form_data( params ) request = Net::HTTP::Post.new(uri.path + "?" + request.body) response = http.request(request) response.code == "200" ? feed = JSON.parse(response.body) : raise("Sorry, an error occured. #{response.body}") return feed end end </code></pre> <p>I am sure someone more experienced than I could improve this - I was about 10 weeks into learning Ruby (and my first programming since Fortran and Pascal at university in the early 90s!).</p>
