CanvasAuthorizer Authorize() Not Returning True On Facebook C# Sdk?
Jan 6, 2011
I downloaded the Facebook C# SDK 4.1.1, and incorporated it on a small ASP.NET 3.5SP1 web project. When I run the application from VS Studio 2008, it allowed me to install my Facebook application. When I log onto facebook, I can see that my app installed, as I see it on my home page left nav.
When I click on the app, it displays the default.aspx page on my facebook app iframe. Looks like it worked, right? No it doesn't because when I debug the page on localhost, I see that the Authorize() on the CanvasAuthorizer app returns FALSE.
I created a web app in IIS 5.0 so that the default vs studio debugger doesn't interfere.
Here are they facebook settings I have set and other relevant information.
I have a call to a function in my business logic area. It should be returning a true.
[URL]
This url above is the culprit. The code doesn't seem to like the .asp type of file. I wonder why this is the case. I get a true response for a html or php type of file. The above returns false. Does anyone know why?

I have a WCF service with cyclic references that I was using the CyclicReferencesAwareAttribute attribute (http://chabster.blogspot.com/2008/02/wcf-cyclic-references-support.html) to solve. However now I want to use the same service with a Silverlight client. Receiving data works well on the Silverlight client with this method, however the CyclicReferencesAwareAttribute attribute does not work on the Silverlight side when I want to send objects back again.
I have changed to use the IsReference property on the data contract which is supposed to get round with this issue. However now the objects that are returned are empty! (All fields are either default or null). This is the same in my ASP.NET client (original) and my Silverlight client.
Has anyone hit is issue before? Here is the attribute [System.Runtime.Serialization.DataContract(Namespace="http://testnamespace.co.uk/entities", IsReference=true)]
I have used the script as follows to display simple alert and confirmation. On confirmation if the result is true i have to execute button click code that was written but i am unable to do that
facebook login is not returning username and email as stated in example
Have implemented the same code given in the example and change the appid and secret code but is not reflecting the email and username but the name is reflecting and the picture is also reflecting.
I'm trying to upgrade my ASP.NET WebForms IFrame Canvas app from Facbook C# SDK 4.02 to 5.03 beta. Most of the changes are fairly straight forward. However, I'm not 100% sure about CanvasAuthorizer.GetLoginUrl().
Here's my code for v4.02
CanvasAuthorizer _authorizer = new CanvasAuthorizer {Perms = "publish_stream,offline_access"};
Uri authurl = _authorizer.GetLoginUrl(new HttpRequestWrapper(Request)); CanvasRedirect(authurl.ToString());
And here's my best guess for v5.03 based on the php example at http://developers.facebook.com/docs/reference/dialogs/oauth
CanvasAuthorizer _authorizer = new CanvasAuthorizer {Perms = "publish_stream,offline_access"};
It took me a little while to figure this out, but the AllowPaging="true" on the FormView seems to be the culprit. I don't have much experience paging from a FormView, but for this requirement the customers wants this kind of UI.I have a FormView with DefaultMode="Edit", which is bound to an EntityDataSource. One of the entity's properties, "ExternalID", determines whether some of the other properties in the entity are read-only. For example, if IsExternal==null, the FirstName, LastName, and Email fields should be rendered as TextBoxes. If IsExternal!=null, the 3 properties should be rendered in Label controls.
We have a web project that contain its business methods in a class library project called "Bll.dll" some methods of Bll.dll return List<> ... from a source - that i don't remember now - told that returning Collection<> is better than returning List<> Is it a valid ? Note that i don't make any process on values returned from BLL methods .. just view it in a web page
I see that only name,group,email address we can access at facebook send button. How can i send to my facebook page wall (where i am admin) by clicking facebook send button. It's by default don't show it.
I need to develop a login where user can login from his facebook account. When user login first time, an auth dialog should open from facebook asking to user for access permission and than it should move to one of my page where I can retrieve user email address and first name & last name through his facebook access token. How to achieve this?
In my facebook canvas applikation, i store the access token in session. (I use ASP.NET MVC)
But i want to store the access token in a database along with the facebook user id that i can save different access tokens for different facebook users accessing my application.
So when i query the facebook user id and if it doen't return any access token, i request permissions and get the access token for that user.
How do i access the Facebook UserID for the user accessing my canvas application before doing any authentification?
i have made a gridview which contains three fields, two textboxes and one combo box. ComboBox fetchs data from table(SQL) and when a combox box triggers, data related to combo must be added in two boxes. i did this throw another button, but i want this to be trigger directly when it clicks..
I'm trying to create a basic application, i created facebook application before but everything has been changed.
I looked every where to create a basic application, but now i'm getting mad because there isn't any working sample. Because of the changed links, facebook api changes, facebook wiki changes i couldn't find a working copy.
write a basic app that gets permission to write user name to screen in facebook developer toolkit asp.net. I looked computerbeacon.net, codeplex, and some other pages but i couldn't succeed.
Edit: I' m adding some screenshots and some codes, it will may be you to find my problem.
I have to develop an authorize filter in asp.net mvc.I have got five categories of users in my site and my site uses custom created authentication system.Now i have a controller action which should be accessible to 3 out of those five type of users.How to create a filter (basically authorize) and use it which fulfills my requirement?I think i need to create the authorize filter with parameter.I should be able to use something like this in my controller action.
Authorize[UsersType="admin,accountant,operator"] public ActionResult Test() { }
After browsing the MVC section on CodePlex I noticed that the [Authorize] attribute in MVC returns a HttpUnauthorizedResult() when authorization fails (codeplex AuthorizeAttribute class). In the source of HttpUnauthorizedResult() from CodePlex is the code (I'm not allowed to enter another URL as my rep isn't high enough, but replace the numbers on the URL above with 22929#266476):
// 401 is the HTTP status code for unauthorized access - setting this // will cause the active authentication module to execute its default // unauthorized handler context.HttpContext.Response.StatusCode = 401;
In particular, the comment describes the authentication module's default unauthorized handler. I can't seem to find any information on this default unauthorized handler. In particular, I'm not using ormsAuthentication and when authorization fails I get an ugly IIS 401 error page. Does anyone know about this default unauthorized handler, and in particular how FormsAuthentication hooks itself in to override it? I'm writing a really simple app for my football team who confirm or deny whether they can play a particular match. If I enable FormsAuthentication in the web.config the redirect works, but I'm not using FormsAuthentication and I'd like to know if there's a workaround.
I'm trying to add a directory for anon access in IIS 7.5. It works under Web Dev but not IIS 7.5
I'm currently using this web.config in the directory. This is a directory with style sheets:
<?xml version="1.0"?>
Note: As an alternative to hand editing this file you can use theweb admin tool to configure settings for your application. Use the Website->Asp.Net Configuration option in Visual Studio. A full list of settings and comments can be found in machine.config.comments usually located in WindowsMicrosoft.NetFrameworkv2.xConfig
I've went to the folder and under Authentication, I've changed anonymous authentication from IIS_USR to pool. This seems to have correct it.
I will reward anyone who provides a very good explanation and resources for understanding this setting. Also, how to apply it globally would be good to know -- for all folders.
So I can get the user logon to some recording data or some thing else.
I was thinking if that was possible to put some value in web config that gets the user logon and if that logon is authorizated for that page it let him open else it close the page...
I have configured forms authentication for my MVC 3 RTM application. I updated the configuration to the following and set the autoFormsAuthentication per the Gu and StackOverflow to false. However, when my application is deployed to my web server (W2k3 Standard SP2, II6) the controllers marked with [Authorize] are always redirected to /Account/LogOn instead of the configured value.
i created a mathod facebookInfo(string username,string password) ,so i received username and password but after receiving its not possible to login at server side,because ther is only one way to connect to facebook using facebook api ie.
facebookservie.ConnectToFacebook();
and its open IE browser,so there is any way to login automatically and get session,using any javascript or nay other way at server side using ASp.net in C#.
I have a WCF service that runs in my web application that provides data to a Silverlight application and is defined as follows (with an appropriate .svc file)....
[ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class DispatchService [code]...
The idea is that the user logs into the website and is then authorised for all services. I do not want to have a login aspect to my Silverlight application to authenticate users.Therefore I dont want anyone to be able to call my service who is not authenticated.
Could I...Somehow determine this for each Operation Contract. I had a look inside the OperationContext object but couldnt find anthing that stood out as a way to determine who the user was.Somehow attribute the ServiceContract so that the method can only be used by authorised users?Put something in my web.config to stop unathorised users from being able to access the folder containing the services?
How can I authorize and authenticate users by roles? I have roles table and user's table, role Id is the primary key in the roles table and foreign key in the user's table.
