  • Auth problem on Facebook using Ruby/sinatra/frankie/facebooker

    - by user84584
    Hello guys, I'm using sinatra/frankie/facebooker to prototype something simple to test the facebook api, i'm using mmangino-facebooker the more recent version from github and I cloned the most recent version of frankie. I'm using sinatra 0.9.6. My main code is as simple as possible: before do ensure_application_is_installed_by_facebook_user @user = session[:facebook_session].user @photos = session[:facebook_session].get_photos(nil,@user.uid,nil) end get "/" do erb :index end get "/:uid/:image" do |uid,image| @photo_selected = session[:facebook_session].get_photos([image.to_i],nil,nil) erb :selected end The index page just renders a link to the other one (identified by regex "/:uid/:image") however I always get an error when it's trying to render the one identified by regex "/:uid/:image" Facebooker::Session::MissingOrInvalidParameter: Invalid parameter /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/parser.rb:610:in `process' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/parser.rb:30:in `parse' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/service.rb:67:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:600:in `post_without_logging' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:611:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/logging.rb:20:in `log_fb_api' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/benchmark.rb:308:in `realtime' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/logging.rb:20:in `log_fb_api' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:610:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:198:in `secure!' ./config/frankie/lib/frankie.rb:66:in `secure_with_token!' ./config/frankie/lib/frankie.rb:44:in `set_facebook_session' ./config/frankie/lib/frankie.rb:164:in `ensure_authenticated_to_facebook' ./config/frankie/lib/frankie.rb:169:in `ensure_application_is_installed_by_facebook_user' I've no idea why, it seems to be related with the auth token I guess.. I logged the request made o the fb rest server: {:sig="4f244d1f510498f4efaae3c03d036a85", :generate_session_secret="0", :method="facebook.auth.getSession", :auth_token="9dae0d02c19c680b574c78d202b0582a", :api_key="70c14732815ace0ae71a561ea5eb38b7", :v="1.0"} {:call_id="1269003766.05665", :sig="194469457d1424dc8ba0678979692363", :method="facebook.photos.get", :subj_id=750401957, :session_key="2.lXL0z3s4_r573xzQwAiA9A__.3600.1269010800-750401957", :api_key="70c14732815ace0ae71a561ea5eb38b7", :v="1.0"} {:sig="4f244d1f510498f4efaae3c03d036a85", :generate_session_secret="0", :method="facebook.auth.getSession", :auth_token="9dae0d02c19c680b574c78d202b0582a", :api_key="70c14732815ace0ae71a561ea5eb38b7", :v="1.0"} The last one gives the error, it could be related with auth_token having the same value in the 1st and on the 3rd ? Cheers and tks, Ze Maria

  • Problem with sessions subdomains and authlogic in Rails.

    - by Alfred Nerstu
    I've got a rails app with authlogic authentication and a username.domain.com structure built with subdomain-fu. But my session breaks when going from domain.com to username.domain.com. I've tried to add config.action_controller.session = {:domain => '.localhost:3000'} to my development.rb but that seams to break authlogic disabling sign out/sign in. Any suggestions on what to do? Thanks in advance!

  • Git checking out problem [fatal: early EOFs]

    - by Style
    Dear all, I'm running a Ubuntu (9.10) server with Git (latest from Ubuntu package manager) installed. Access to the Git is via SSH. On windows machines, I'm using Cygwin to push/pull code. I can push my project code onto the server but when I do a clone or pull, it returns a [fatal: early EOFs] error at about 75-80%. Upon further investigation, it seems like textual data has no issue when pulled/cloned but when the jar files and images are pulled from Git, the error will occur. Any suggestion/advice that can help to resolve this issue? Thanks in advance.

  • Problem with Json Date format when calling cross-domain proxy

    - by Christo Fur
    I am using a proxy service to allow my client side javascript to talk to a service on another domain The proxy is a simple ashx file with simply gets the request and forwards it onto the service on the other domain : using (var sr = new System.IO.StreamReader(context.Request.InputStream)) { requestData = sr.ReadToEnd(); } string data = HttpUtility.UrlDecode(requestData); using (var client = new WebClient()) { client.BaseAddress = serviceUrl; client.Headers.Add("Content-Type", "application/json"); response = client.UploadString(new Uri(webserviceUrl), data); } The client javascript calling this proxy looks like this function TestMethod() { $.ajax({ type: "POST", url: "/custommodules/configuratorproxyservice.ashx?m=TestMethod", contentType: "application/json; charset=utf-8", data: JSON.parse('{"testObj":{"Name":"jo","Ref":"jones","LastModified":"\/Date(-62135596800000+0000)\/"}}'), dataType: "json", success: AjaxSucceeded, error: AjaxFailed }); function AjaxSucceeded(result) { alert(result); } function AjaxFailed(result) { alert(result.status + ' - ' + result.statusText); } } This works fine until I have to pass a date. At which point I get a Bad Request error when the proxy tries to call the service I did have this working at one point but have now lost it. Have tried using JSON.Parse on the object before sending. and JSON.Stringify, but no joy anyone got any ideas what I am missing

  • generateUrl problem

    - by Daniel Hertz
    I am trying to generate a url but I keep getting a strange warning even though it works. I am making an api xml page and I use the following call in the controller: public function executeList(sfWebRequest $request) { $this->users = array(); foreach($this->getRoute()->getObjects() as $user) { $this->users[$this->generateUrl('user_show', $user, true)] = $user->asArray($request->getHost()); } } The user_show route is as follows: # api urls user_show: url: /user/:nickname param: { module: user, action: show } And the xml outputs as follows: <br /> <b>Warning</b>: array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br /> <br /> <b>Warning</b>: array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br /> <br /> <b>Warning</b>: array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br /> <?xml version="1.0" encoding="utf-8"?> <users> <user url="http://krowdd.dev/frontend_dev.php/user/danny"> <name>Danny tz</name> <nickname>danny</nickname> <email>[email protected]</email> <image></image> </user> <user url="http://krowdd.dev/frontend_dev.php/user/adrian"> <name>Adrian Sooian</name> <nickname>adrian</nickname> </user> </users> So it outputs the correct xml but I do not know why it throws thows warning when calling the generateurl method.

  • dublicate display of Posts from controller - conditions and joins problem - Ruby on Rails

    - by bgadoci
    I have built a blog application using Ruby on Rails. In the application I have posts and tags. Post has_many :tags and Tag belongs_to :post. In the /views/posts/index.html view I want to display two things. First is a listing of all posts displayed 'created_at DESC' and then in the side bar I am wanting to reference my Tags table, group records, and display as a link that allows for viewing all posts with that tag. With the code below, I am able to display the tag groups and succesfully display all posts with that tag. There are two problems with it thought. /posts view, the code seems to be referencing the Tag table and displaying the post multiple times, directly correlated to how many tags that post has. (i.e. if the post has 3 tags it will display the post 3 times). /posts view, only displays posts that have Tags. If the post doesn't have a tag, no display at all. /views/posts/index.html.erb <%= render :partial => @posts %> /views/posts/_post.html.erb <% div_for post do %> <h2><%= link_to_unless_current h(post.title), post %></h2> <i>Posted <%= time_ago_in_words(post.created_at) %></i> ago <%= simple_format h truncate(post.body, :length => 300) %> <%= link_to "Read More", post %> | <%= link_to "View & Add Comments (#{post.comments.count})", post %> <hr/> <% end %> /models/post.rb class Post < ActiveRecord::Base validates_presence_of :body, :title has_many :comments, :dependent => :destroy has_many :tags, :dependent => :destroy cattr_reader :per_page @@per_page = 10 end posts_controller.rb def index @tag_counts = Tag.count(:group => :tag_name, :order => 'updated_at DESC', :limit => 10) @posts=Post.all(:joins => :tags,:conditions=>(params[:tag_name] ? { :tags => { :tag_name => params[:tag_name] }} : {} ) ).paginate :page => params[:page], :per_page => 5 respond_to do |format| format.html # index.html.erb format.xml { render :xml => @posts } format.json { render :json => @posts } format.atom end end

  • Response.TransmitFile problem

    - by geoff
    I have the following code delivering a file to users when they click on a download link. For security purposes I can't just link directly to the file so this was set up to decode the url and transmit the file. It has been working fine for a while but recently I started having problems where the file will start downloading but there's no indication of how large the file is. Because of this when the download should stop, it doesn't. The file is about 99mb but when I download it, the browser just keeps downloading way beyond 100mb. I don't know what it's downloading but if I don't cancel it, it doesn't stop. So, my question is, is there either an alternative to transmitfile or a way to make sure the size of the file is sent also so that it stops at the right time? I don't want to use writefile because I don't want to load the entire file into memory since it's so large. Thanks. Here is the code: string filename = Path.GetFileName(url); context.Response.Buffer = true; context.Response.Charset = ""; context.Response.Cache.SetCacheability(HttpCacheability.NoCache); context.Response.ContentType = "application/x-rar-compressed"; context.Response.AddHeader("content-disposition", "attachment;filename=" + filename); context.Response.TransmitFile(context.Server.MapPath(url)); context.Response.Flush();

  • C# HMAC Implementation Problem

    - by Emanuel
    I want my application to encrypt a user password, and at one time password will be decrypted to be sent to the server for authentication. A friend advise me to use HMAC. I wrote the following code in C#: System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding(); byte[] key = encoding.GetBytes("secret"); HMACSHA256 myhmacsha256 = new HMACSHA256(key); byte[] hashValue = myhmacsha256.ComputeHash(encoding.GetBytes("text")); string resultSTR = Convert.ToBase64String(hashValue); myhmacsha256.Clear(); How to decode the password (resultSTR, in this case)? Thanks.

  • Excel Plug-In Assembly Loading Problem (Access Denied)

    - by PlagueEditor
    I am developing an Excel 2003 add-in using Visual Studio 2008. My add-in loads fine; however, it loads plug-ins from other C# DLL's. I would like this to be done dynamically at run time so referencing them during development is something I would rather not do. Anyways, anytime I try to load a DLL from the Excel add-in at start up, it throws a security exception. This particular example is HTML Agility Pack. It's not a plug-in but a plug-in's dependency. But nonetheless it won't even load: {System.IO.FileLoadException: Could not load file or assembly 'HtmlAgilityPack, Version=1.4.0.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a' or one of its dependencies. Failed to grant permission to execute. (Exception from HRESULT: 0x80131418) File name: 'HtmlAgilityPack, Version=1.4.0.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a' ---> System.Security.Policy.PolicyException: Execution permission cannot be acquired. at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Boolean checkExecutionPermission) at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Int32& securitySpecialFlags, Boolean checkExecutionPermission) at System.Reflection.Assembly.nLoadFile(String path, Evidence evidence) at System.Reflection.Assembly.LoadFile(String path) at Cjack.Druid.SourcePluginManager.LoadPlugin(String filePath) in C:\Documents and Settings\Annie Tormey\My Documents\Visual Studio 2008\Projects\DruidAddin2003\Druid\SourcePluginManager.cs:line 26 } This is extremely frustrating because it runs perfectly fine for Office 2010 and as a standalone application. Thank-you to anyone who can give me an answer as to why this is happening or a solution to fix it. Thank-you for your time.

  • Problem using setEmptyView on a ListActivity

    - by Pentium10
    I have the following setup, and the empty view text doesn't show up... protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getListView().setEmptyView(findViewById(R.id.empty)); getListView().setTextFilterEnabled(true); setListAdapter(null);// to have empty list } The layout file is: <?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/myScrollLayout" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android"> <FrameLayout android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1"> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:drawSelectorOnTop="false" /> <!-- Here is the view to show if the list is emtpy --> <ScrollView android:id="@android:id/empty" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/emptyText" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/contact_empty_help" android:textSize="20sp" android:textColor="?android:attr/textColorSecondary" android:paddingLeft="10dip" android:paddingRight="10dip" android:paddingTop="10dip" android:lineSpacingMultiplier="0.92" /> </ScrollView> </FrameLayout> </LinearLayout> String is defined as: <string name="contact_empty_help">"You don't have any contacts to display.\n\nTo add contacts, you have to:\n \n<li><font fgcolor="#ffffffff">Go to <b>Contacts</b></font> application to create new contacts\n</li> \n<li><font fgcolor="#ffffffff"><b>Import from VCF file</b></font>, this is available in Contacts menu, the file most be on the root of the SD card\n</li>" </string> Since the list is empty, it should show me the text defined.

  • How to Solve N-Queens Problem in Scheme?

    - by Philip
    Hi, I'm stuck on the extended exercise 28.2 of How to Design Programs. Here is the link to the question: http://www.htdp.org/2003-09-26/Book/curriculum-Z-H-35.html#node_chap_28 I used a vector of true or false values to represent the board instead of using a list. This is what I've got which doesn't work: #lang Scheme (define-struct posn (i j)) ;takes in a position in i, j form and a board and returns a natural number that represents the position in index form ;example for board xxx ; xxx ; xxx ;(0, 1) - 1 ;(2, 1) - 7 (define (board-ref a-posn a-board) (+ (* (sqrt (vector-length a-board)) (posn-i a-posn)) (posn-j a-posn))) ;reverse of the above function ;1 - (0, 1) ;7 - (2, 1) (define (get-posn n a-board) (local ((define board-length (sqrt (vector-length a-board)))) (make-posn (floor (/ n board-length)) (remainder n board-length)))) ;determines if posn1 threatens posn2 ;true if they are on the same row/column/diagonal (define (threatened? posn1 posn2) (cond ((= (posn-i posn1) (posn-i posn2)) #t) ((= (posn-j posn1) (posn-j posn2)) #t) ((= (abs (- (posn-i posn1) (posn-i posn2))) (abs (- (posn-j posn1) (posn-j posn2)))) #t) (else #f))) ;returns a list of positions that are not threatened or occupied by queens ;basically any position with the value true (define (get-available-posn a-board) (local ((define (get-ava index) (cond ((= index (vector-length a-board)) '()) ((vector-ref a-board index) (cons index (get-ava (add1 index)))) (else (get-ava (add1 index)))))) (get-ava 0))) ;consume a position in the form of a natural number and a board ;returns a board after placing a queen on the position of the board (define (place n a-board) (local ((define (foo x) (cond ((not (board-ref (get-posn x a-board) a-board)) #f) ((threatened? (get-posn x a-board) (get-posn n a-board)) #f) (else #t)))) (build-vector (vector-length a-board) foo))) ;consume a list of positions in the form of natural number and consumes a board ;returns a list of boards after placing queens on each of the positions on the board (define (place/list alop a-board) (cond ((empty? alop) '()) (else (cons (place (first alop) a-board) (place/list (rest alop) a-board))))) ;returns a possible board after placing n queens on a-board ;returns false if impossible (define (placement n a-board) (cond ((zero? n) a-board) (else (local ((define available-posn (get-available-posn a-board))) (cond ((empty? available-posn) #f) (else (or (placement (sub1 n) (place (first available-posn) a-board)) (placement/list (sub1 n) (place/list (rest available-posn) a-board))))))))) ;returns a possible board after placing n queens on a list of boards ;returns false if all the boards are not valid (define (placement/list n boards) (cond ((empty? boards) #f) ((zero? n) (first boards)) ((not (boolean?

  • Nested Row problem

    - by Patrick
    Hi, I'm using the 1kb css grid framework for a site, and although nested rows are apparently supported by the framework, when I try to drop in a nested row it doesn't work! Sorry not to explain it better - the site's here, may be easier to just look at the source: http://2605.co.uk/saf/build/ the grid: /grid.css the stylesheet: /style.css I'm a graphic designer hacking his way through a site he shouldn't be having to build but there's no budget to speak of! Cheers for any help, Patrick
