I wanted to get IMSI number on openwrt with freeradius(eap-sim) authenticate but I do not have parameters of kc, rand and SERS.
How to authenticate successfully without these parameters?
Unless the device is using pseudonyms, the IMSI will be provided in the initial EAP-Identity-Response. You don't need to complete authentication in order to get it.

Has anyone had success using Stripe connect with an iOS app. I have a few questions:
I'm following the guidelines here: https://stripe.com/docs/connect/getting-started
Registering an Application: easy, no problem here
Then a little further down:
Send your users to Stripe: again, easy no problem here, I just have a button that opens up the link in a UIWebView. I assume having the client_id in the URL is fine? A lot of my uncertainty is what IDs/keys I should hard-code into the app
Then a little further down:
After the user connects or creates a Stripe account, we'll redirect them back to the redirect_uri you set in yourapplication settings with a code parameter or an error.
What I'm doing here is using the UIWebview's webView:shouldStartLoadWithReqest:navigationType delegate method to check for the string "code=" in the URL. If it finds that, then I'm able to grab the "code" parameter. So in reality, the redirect_uri is completely unnecessary for me. Is this the right way to handle this? Should I be doing this within my app or on my server?
After receiving the code, we are supposed to make a POST call to receive an access_token. Again, should this be done within the app or on the Server? It requires the use of a secret_key, so I'm guessing server? And how do I send credit card information along with this token if the token needs to be sent to the server? I know how to obtain the card number, exp date, and CVV. But in terms of passing it to the server (with or without the token) is something I'm not sure of.
Then when it comes to actually writing PHP, Ruby, or Python code on the server, I'm at a total loss.
Any help would be greatly appreciated.
You should setup a small web app to create stripe charges and storing you customers Authorization Code. Configure two routes in your web app for redirect_uri and webhook_uri and add the url in your Stripe Apps settings. The charges should be created from a server side app because it requires the secret_key / authorization_code which should not be stored in an iPad app. Otherwise they may lead to a security leak. I'm trying to describe the concept below:
Provide the stripe connect button in your app and set the link to open in Safari (not in an web view). You should add a state parameter to the url with an id which is unique to your users.
On tapping the button your user will be redirected to Stripe where s/he will be asked to authorize your application. Upon authorization stripe will hit your redirect_uri with a authorization_code and the state you previously provided. Do a post call according to Stripe Documentation with the authorization_code to get an access_token. Store the access_token mapped with the state in a database.
Define a custom url scheme in your app. Invoke the custom url from your web app. The user supposed to open the url in mobile safari. So invoking the custom url will reopen your application. You can pass an additional parameter to indicate failure / success. In your app update the view based on this parameter.
Now you are all set to create a charge on your server on behalf of the iPad user. Use stripe iOS sdk to generate a card_token from the card information. It'll require your stripe publishable_key. Then define an api in your web app which takes 3 parameters: card_token, user_id and amount. Call this api from your iPad app whenever you want to create a charge. You can also encrypt this information with a key if you're worried about security using any standard encryption method. You can easily decrypt the info in your web app as you know the key.
When this api is called from the iPad app you'll receive the user_id (which you saved as state previously), card_token and amount. Retrieve the access_token mapped to the user_id (or state). You can then made a charge on behalf of the user using the access_token, card_token and amount.
You can use ruby / php / python / node in the server as Stripe provides sdk for them. I assume other languages can be used as well as there is a REST interface.
Please note that this is just a concept. It should work like it but I haven't implemented it yet. I'll update this answer with sample code when I'm done.
You can use UIWebView. You will still need to use redirect urls and monitor the redirect using the delegate "webView:shouldStartLoadWithRequest:navigationType:"
I try to get the signed request to login the user via a webservice but I only have access to the accessToken on FBSession.
I saw this link
Facebook Signed Request for iOS (HMAC SHA256)
who shows how to convert the signed_request but doesn't show how to get it.
Need help :)
If I undersand you right you want your app to login and then make a call to a server where you need to check the users credential again.
I used this tutorial for the authentication.
Then when I call the server I send the accessToken property as a parameter to check the users credentials on the server. You can get the token value like this:
FBSession.activeSession.accessToken
On the server side you can then set the access token to the value you got from the app.
I compiled a gist that generates a signed request which you can then use to authenticate a user on your server without having to query the graph API.
You can find it here: https://gist.github.com/3962188
You can find the original question I compiled it for here: Facebook iOS SDK to return a signed request object upon login
Please note that most of the code is simply a compilation of existing open source code, but I haven't seen any fully working implementation like this anywhere.
I'm trying to implement Soundcloud connect and having a weird issue.
First thing I do is send my users to
https://soundcloud.com/connect?client_id=MY_CLIENT_ID&redirect_uri=http://myredirecturl.example.com&state=RANDOM_STRING&display=page&response_type=code&scope=email
When users connect they get redirected to
http://myredirecturl.example.com?error=invalid_scope&error_description=The+requested+scope+is+invalid%2C+unknown%2C+or+malformed.&state=RANDOM_STRING
The same happens if I use scope=*.
However, if I use scope=non-expiring it lets me go through, but I need the users email and that type of scope doesn't have enough grants.
I thought it had something to do with my app being in development mode, but Osman at Soundcloud said it doesn't.
Thanks.
The 'email' scope is not available to all integrations. It's used for a few custom integrations that have provided us with accepted terms of service / privacy policies. There is no way to get a user's email address using the SoundCloud API.
You should however be able to use the '*' scope to get an expiring access token. I'll check with our app team to see why this is giving you an error. I'll edit my answer once I have more information there.
For your purposes, I would stay with the 'non-expiring' scope and simply prompt a user for their email address (providing them with a way to agree to your terms of use / privacy information).
Using scope=* sometimes doesn't work because the url is not properly encoded. If you are getting this error while using the * wildcard, try properly encoding the url, using a function like urlencode() (for PHP).
I'm looking for a solution similar to the iPhone Facebook Connect (https://github.com/facebook/facebook-ios-sdk) for the BlackBerry platform. Basically, I need my users to authenticate against Facebook from within a native BlackBerry application (so, not a Web based mobile application). Is there a library I could use, and if not, what will be the correct approach to achieve this?
Thanks in advance!
Options for BlackBerry are:
Use Facebook Platform for Mobile
Use REST API approach provided by Eki Y. Baskoro
Try to port JavaFB from J2SE to J2ME
I managed to go through Facebook Connect authentication within my BB app. After cracking my head for three days I realised that it is the URL that is the culprit!
Basically these are what you need (assuming you are developing for 4.5 platform):
Using Browser Field, do a POST to http://m.facebook.com/login.php (the mobile version of Facebook) passing all the necessary arguments as per the Desktop application counterparts (one challenge is to get the signature generation correct).
Once the User successfully grants access, capture the URL of the success screen. You will obtain your auth_token.
Do a POST to the REST server to obtain the session key and secret given the auth_token you obtain.
Save the returned session key and secret, persist it, and wholla! your app is up and running.
I am developing a custom LoginScreen and FacebookFacade object to incorporate the first three steps above, if anyone is ever interested to reuse my code. It'll be GPLed, I suppose ;)
Afzal, I had a similar problem and I've found out that I actually had a problem with my connection string. You can look at the following link there is some explanation and code for creating the correct connection string
http://www.localytics.com/blog/post/how-to-reliably-establish-a-network-connection-on-any-blackberry-device/
and just add the connection string to the FetchThread where it opens the connection:
connection = (HttpConnection)Connector.open(absoluteUrl+getConnectionString());
I'm trying to write a web application that would use Twitter via OAuth.
I run my local server as 'localhost', so I need the callback URL to be something like http://localhost/something/twitter.do but Twitter doesn't like that: Not a valid URL format
I'm probably going to do a lot of tests, but once I've approved my app with my username, I can't test again can I? Am I supposed to create multiple twitter accounts? Or can you remove an app and do it again?
You can use 127.0.0.1 instead of localhost.
You can authorize your app as many times as you like from the same twitter account without the necessity to revoke it. However, the authenticate action will only prompt for Allow/Deny once and all subsequent authenticate requests will just pass through until you revoke the privilege.
Twitter's "rate limiting" for API GET calls is based on IP address of the caller. So, you can test your app from your server, using the same IP address, and get (once approved) 15,000 API calls per hour. That means you can pound on your app with many different usernames, as long as your approved IP address remains the same.
When you send the e-mail to Twitter to ask for an increase to your rate limit, you can also ask for the increase to apply to your Twitter username too.
I believe Twitter requires you - if you need to change your IP address, or change the username that is using the app - to send in another request asking for the rate limit increase for that new IP address or username. But, in my experience, Twitter has been pretty quick at turning around these requests (maybe less than 48 hours?).
use like this
for Website :http://127.0.0.1
and for callback URL: http://127.0.0.1/home
or any of your page address like http://127.0.0.1/index
Have you tried creating your own caching mechanism? You can take the result of an initial query, cache it on thread local, and given an expiration time, refresh from Twitter. This would allow you to test your app against Twitter data without incurring call penalties.
There is also another solution (a workaround, rather) which requires you to edit your hosts file.
Here is how you do it on a linux box:
Open your /etc/hosts file as root. To do this, you can open a terminal and type something like sudo vi /etc/hosts.
Pick a non-existent domain to use as your local address, and add it to your hosts file. For example, you will need to add something similar to the following at the end.
127.0.0.1 localhost.cep # this domain name was accepted.
So, that's pretty much it. Pointing your browser to localhost.cep will now take you to your local server. Hope that helped :)
In answer to (1), see this thread, in particular episod's replies: https://dev.twitter.com/discussions/5749
It doesn't matter what callback URL you put in your app's management page on dev.twitter.com (as long as you don't use localhost). You provide the 'real' callback URL as part of your request for an OAuth token.
1.) Don't use localhost. That's not helpful. Why not stand up another server instance or get a testing vm slice from slicehost?
2.) You probably want a bunch of different user accounts and a couple different OAuth key/secret credentials for testing.
You were on the right track though: DO test revoking the app's credentials via your twitter account's connections setting. That should happen gracefully. You might want to store a status value alongside the access token information, so you can mark tokens as revoked.
