I have an asp.net site and I use log in to facebook calling
http://www.facebook.com/login.php?api_key=API_KEY&connect_display=popup&v=1.0&next=http://localhost/site/login.aspx&cancel_url=http://www.facebook.com/connect/login_failure.html&fbconnect=true&return_session=true&skipcookie=true
Logs in very well, returns to my site, I see session parameter in url, but I can't catch any postback or something.
Could you help me, please?
Thank you
A couple of things to check:
Make sure that http://localhost/site (or whatever the url for the root of your app is) is set in your application's connect settings
If you're using the Visual Studio development studio development web server (Cassini), your app's url will include a port (for example, http://localhost:34256/site). This url (including the port) will need to be specified in your connect url in your application's settings on Facebook.

I am developing a web app with Facebook integration and I can't figure out why I can't test the login function locally. I have looked through the answers here (How to Test Facebook Connect Locally) and have tried to follow the steps of having the app in test mode, setting the site URL and the domain.
Based on FBs documentation here: https://developers.facebook.com/blog/post/2018/06/08/enforce-https-facebook-login/
I should be able to use http for localhost development, but I get the error
The method FB.api can no longer be called from http pages. https://developers.facebook.com/blog/post/2018/06/08/enforce-https-facebook-login/
and can't log in. Below are pictures of my app settings (including an indication it is an app in 'test mode').
So this is really only a half answer, but it seemed easier for me to just force https for my local development using mkcert (https://github.com/FiloSottile/mkcert). After creating local certs I updated my site URL to say https://localhost:8080 and I am able to log in without issue.
I have a project in Ionic 4, when I do ionic serve it runs at localhost:8100/
Now when it loads home page, the URL is localhost:8100/home, if I open contact page the URL becomes localhost:8100/contact.
When I try to copy the above URL and hit, then it says -
Sorry, this page doesn't exist. Please check the URL or go back a page.
What do I need to do to get this working?
Based on your comments this is happening because your server does not support fallback. So when you enter a url manually, the server is trying to find that page, but you only have index.html in your app because of Client side routing.
If the app uses the Angular router, you must configure the server to
return the application's host page (index.html) when asked for a file
that it does not have.
The configuration is specific to your server or cloud platform. You can check Angular deployment for more info.
This regularly should not happen and you can't do anything for this. Try to upgrade your ionic to the latest with nodejs since the error my be from currupted project creation. Then after update create a new project and it should go good.
I am developing a Telco application (Dyanamic Web application project to send and receive sms) using Eclipse & tomcate version 7
When I try to run it on
http://localhost:8080/SMS1
It gives an error message HTTP-ERROR-CODE:302
What should I do to resolve this error
This is the link to Application and video tutorial what I am following
https://drive.google.com/file/d/0B3VmCeqDC7SDcFZaWVZhRUNmaTQ/edit?usp=sharing
HTTP code 302 is a standard "redirect" message--that is, it tells your web browser that the page was moved and where the new page can be found. I'm guessing whatever you're using as a web browser (Eclipse?) just doesn't handle that type of redirect. Try using a standard web browser like Chrome or Mozilla to see if that helps...
Also a guess, but the redirect may be trying to move you to HTTPS instead of HTTP, and your certificates may not be set up properly, or the port isn't enabled, or there may be some other problem with your HTTPS configuration. If the app is supposed to work over HTTPS, try going directly to the HTTPS version of the link to see if that's the real issue.
A third guess is the app may be trying to redirect you to a login page if you're not logged in, and maybe it can't find it. I'd need to know a lot more about the built product and I really don't want to mess with some guy's shared Eclipse project. Tell them to use a build tool!
I am developing a website which uses the Facebook login. Now, I want to be able to get this to work both in my production environment, as well as in my development environment.
On Facebook, I can give ONE site url, which Facebook can redirect to. This worked great during my development phase, but now I want it both to work in production, but also while developing my solution.
I guess one way would be to run my application on the local IIS with my domain-navn and change my hosts file, but that can't seriously be the most easy solution!?
- What is the easiest way to get it to work in both environments?
Update: As of 2018 the path to this setting is now Products > Facebook Login > Settings > Client OAuth Settings the rest of this answer is still valid.
There is a better way. You just need to add valid callback URL's for your localhost to Settings > Advanced > OAuth Settings.
This method allows you still have your production website URL while allowing oauth from dev, staging, production, etc.
After I have worked with this for ~6 months, I have found a solution which works really well, based on the other two answers.
In Facebook I add two apps:
Production app
Dev app
Then, in my web.config app settings I have:
<!--Prod-->
<add key="_FacebookApiId" value="id"/>
<add key="_FacebookApiSecretId" value="secret_id"/>
<!--Dev-->
<add key="FacebookApiId" value="dev_id"/>
<add key="FacebookApiSecretId" value="dev_secret_id"/>
Which of course is read through a helper-class.
Then it works seamlessly on both production and localhost, and both myself and my team is happy.
I have the same problem.
The only solutions I have found are:
yes... edit the host file on your local machine: How to Test Facebook Connect Locally
create another Facebook app only for development purposes: Facebook Oauth on localhost for testing during development (the blog is about Rails but the solution to use different apps depending on the environment is still valid for other languages)
Facebook only allows localhost OAuth redirects when your app is in development mode. This means you can't run your application in production and perform local development tests.
Instead, you need to create a test variant of your app. Head to https://developers.facebook.com and view the dashboard for your production application. Click the drop-down menu at the top-left and choose Create Test App.
This populates a test application with almost the same settings as your production app. However, it gives you a new app ID and app secret, so you'll need to toggle these settings when running in development mode (as other answers suggest).
Here's some further info on test apps: https://developers.facebook.com/docs/apps/test-apps/
Following the advice in this answer, it will work if set the Mobile URL to be your development domain (ie. localhost) and the Site URL to be your production domain.
The updated way.
In the App Dashboard, choose your app and go to Products > Facebook
Login > Settings. Under the Client OAuth Settings, enter your redirect
URL in the Valid OAuth redirect URIs field for successful
authorization.
Go to https://developers.facebook.com/docs/facebook-login/web for more info.
I am developing a Facebook application and I am using Facebook C# SDK v4.2.1 to help with authentication. I am building the application using ASP.NET MVC 2 and am hosting it in Windows Azure (SDK v1.2).
Everything has been running fine when I had my application in a full browser window, but now when I am attempting to IFrame it in Facebook, I run into session problems. The behavior is that a new session is created on every new page request so the user always comes back to the application's login page. I can see that that Facebook session is valid when Facebook redirects back to the application after authorization, but when I set some session variables and redirect to another page, the session is gone.
When I debug the application locally, both as a standalone web application and in the Development Fabric, everything works fine. It is only when it's published to Azure that I get the problems. I have tried to have a local debug environment that is very similar to production where I have the facebook application at apps.facebook.com/myappnamedev that points to localhost on a specific port.
I just now also discovered that I only see the problem in IE (I am using v.8). Firefox v3.6 and Safari v.5 works fine.
Any ideas to help my troubleshooting? I have spent 10 hours on it and it's getting really frustrating... I am happy to paste code/configuration info if needed, just let me know.
Thank you in advance!

I solved this. The redirect from Facebook after authentication landed on different pages in my development environment compared when deployed to Azure. I moved my authentication logic to global.asax instead.
