OAuth Library
This is OAuth Library for Corona.
download link is http://bit.ly/corona-oauth
**Update**
version 2.0 Release note
・async http request support(network library)
・test using twitter oauth system
・fix some bugs
(only sync http request version for android is preparing now.)
main.lua for test tweet
http://bit.ly/corona-oauth-main
(this main.lua has some bug. (e.g. error handling) )
(can not use simulator. xcode simulator or device is OK)
next version road map
・Authorization header support
・OAuth 2.0 support
・more other oauth1.0a system support
(maybe this version support only Twitter oauth system now)
・retrieve access token support
・more network error handling

Sorry , When I write this library, I forget about SSL.
I'm rewritten this oauth-library using network library now.
please wait :)
I was just about to ask about async and ssl.....glad to hear you are working on it with the new network support. I look forward to checking it out when you are ready for testers ;-)
@muxukeikei Any progress on this? Looks like a lot of people need OAuth access for Twitter, Facebook etc.
muxukeikei,
I actually got it working for what I needed. I'll probably rewrite it for async somewhere in the next couple weeks
Did you get it working with Twitter (which is what I need)?
Maybe you could share what you have, and let others add to it/improve it?
@spjnowak
Yea, got it working with Twitter. Once I rewrite it using async I'll post code.
I can live without the async, need it for dropbox integration. Feel free to send it to me privately ;-)))
I can live without the async, need it for dropbox integration. Feel free to send it to me privately ;-)))
I'm losing track of who's writing what code now! And who's going to finish something first ... I just need to post a tweet - do I need async? ssl?
muxukeikei? trollapps?
Can we get an example of this working with Twitter?
All,
here is what I've come up with using code from muxukeikei. This will work with twitter as well.

and here's an example of utilizing it with twitter. let me know if you run into problems, I had to single out chunks of code from my project and might have missed some stuff. the responseToTable function is what I use to turn url variables into a table, anyone know a better solution?

I'm beginning to work with this, I'll post again with progress or lack thereof :)
Unfortunately, I can't get this to work, and it may be a configuration issue as much as it is a coding issue. My goal is to simply post a tweet as this is all the functionality I really need.
The first thing I notice is that in your
1 | local twitter_request = (oAuth.getRequestToken(consumer_key, "your website", "http://twitter.com/oauth/request_token", consumer_secret)) |
You have a string of "your website". I don't have a website, my game is simply an iPhone app and on my Twitter Dev account, my game is registered as a client, not a website (is that something I need to change?). I am not sure if there is some kind of App Id I need to be passing in (like Facebook?) or just pass in a blank? As of now I am using a blank string.
I am able to get as far as launching a web pop-up, having the user log in, having the user give my application permissions, and then being sent to a page with a "validation code" they are supposed to enter inside of my game. Which of course leaves me bewildered...
Code wise, the access_token and access_token_secret are not being given to me, which leaves me unable to post anything.
One more caveat: On the Twitter Dev account, there is an oauth 1.0a access_token and access_token_secret I can use... I am not sure if I could or should be using these for something.
Here is my code. The callTwitter function is attached to a button.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | --Twitter Functions local postTwitter = function(message) local params = { {"status", message} } if access_token ~= nil then oauth.makeRequest("http://api.twitter.com/1/statuses/update.json", params, consumer_key, access_token, consumer_secret, access_token_secret, "POST") end end local callTwitter = function(message) local twitter_request = oauth.getRequestToken(consumer_key, "", "https://twitter.com/oauth/request_token", consumer_secret) local twitter_request_token = twitter_request.token local twitter_request_token_secret = twitter_request.token_secret print("TOKEN CallTwitter:") print(twitter_request_token) local twitterListener = function(event) local remain_open = true local url = event.url if url:find("oauth_token") then url = url:sub(url:find("?") + 1, url:len()) local authorize_response = oauth.responseToTable(url, {"=", "&"}) remain_open = false local access_response = oauth.responseToTable(oauth.getAccessToken(authorize_response.oauth_token, authorize_response.oauth_verifier, twitter_request_token_secret, consumer_key, consumer_secret, "https://api.twitter.com/oauth/access_token"), {"=", "&"}) access_token = access_response.oauth_token access_token_secret = access_response.oauth_token_secret user_id = access_response.user_id screen_name = access_response.screen_name postTwitter(message) end return remain_open end native.showWebPopup(10, 10, display.contentWidth - 30, display.contentHeight -10, "https://api.twitter.com/oauth/authorize?oauth_token=" .. twitter_request_token, {urlRequest = twitterListener}) end |
Massively appreciate the help.
the access_token is given to you in a URL that's passed back to your website url.
the access_token given to you on the twitter website is for logging in as yourself without authentication for testing purposes.
you need to have a website in order to skip the copy and pasting of the code that the user is given. for example if you were to put google.com as your website, it would pass back
Ok. I am guessing that means I would have to have a DB on that website to save the token and token secret, and then have my app reach back to that website and grab it. Given that at this point in time, that's a lot of infrastructure just to display "I just beat level 5 of this cool game!" without having the user enter a quick twitter code...
What would I have to change in my code to get the twitter code thing working?
(As mean as it may sound, I can advertise twitter functionality in my app the same way regardless of whether the user has to enter a code or not)
no, it doesn't require any functionality from a web server. the webPopup is forwarded to your url, with the URL variables included, that's what this is for:
1 | if url:find("oauth_token") then |
it searches the URL of the webPopup for the URL variables, once it gets them, they are stored and the webPopup is closed
So what you're telling me is that I just need to set up my application as a website (on Twitter Dev) and have a blank webpage somewhere and to just literally put that in place of the "your website" string with nothing else needed?
Ohhh I think I see what you're talking about ...you are saying to:
1. Change to a Website on Twitter Dev
2. Create a Page that just lists out the tokens in the HTML
3. The Code will just search that url's html for the tokens and grab them.
4. Pop-up closes and you can annoy the world with stupid tweets :P
basically, yes. the webpage i forwarded it to for my app is actually a blank webpage. just set it as "http://google.com" for now if you want, i just tested, and it works fine
no, the html page isn't what the code is searching, it's the url.
lol I'm so close! I am able to approve the app now that it is a "website" without the code and the approval shows up under the list of installed apps. Better yet, the google.com thing works, and as you said the pop-up automatically closes because it found the url with the oauth token. It is also able to pull in the token and the verifier into my app.
However, I still can't tweet and here's why:
1 | local access_response = oauth.responseToTable(oauth.getAccessToken(authorize_response.oauth_token, authorize_response.oauth_verifier, twitter_request_token_secret, consumer_key, consumer_secret, "https://api.twitter.com/oauth/access_token"), {"=", "&"}) |
is giving me back a "Invalid / expired Token" as the result. I have confirmed that the token and verifier passed in to the method match what I get in the callback (so it's not a parsing issue). The other values passed in to the getAccessToken method also seem to be correct when I look at them.
Any ideas what may be causing this?
Hi all,
I'm been using the code of this post. I've got to authenticate in Twitter and publish a twet, and to authenticate in Twitpic using the same code. My problem at this time is this, how can I upload a image using the Twitpic API??? I've tried a lot of things, but I haven't got anything. My last test was:
- load a image.
- include it in a display group.
- save this display group in a file.
- then, I read it using the Lua's io and file API.
- In this point, I get authorization in Twitpic, and when I try to publish the image, twitpic says that the image is not valid. Maybe wrong format.
Others test were: to codify the read file in mime.b64 format, to use http.request after the OAUth dance,... but I always got the same result :-(
any idea??
Did anyone ever solve any of this? None of the sample code here works.
If you have working code, I'm sure a lot of other Corona programmers would love to see it!
+1 -- is oauth implemented yet? Anyone have a good & stable Twitter library
I have been using trollapps' code for a non-Twitter API. It seems to wok fine if they is no parameter specified with the URL (example: http://www.test.com/testpage/..). But the moment I change the URL to something like http://www.test.com/testpage?para=1¶=2.., it fails with invalid signature problem.
Anyone using the above code for any non-Twitter service?
I can't seem to get this code to work for me. I get the following error:
Runtime error
/Users/Peter/Desktop/oAuthTest/main.lua:23: attempt to call field 'responseToTable' (a nil value)
over this line:

"/lists.json", "", consumer_key, access_token, consumer_secret, access_token_secret, "GET") end return remain_open end |
Does anyone know how to fix this?
Wow. I have no idea how to use this thing.
I got as far as getting a consumer key and consumer secret from twitter and using "options.token_ready_url = "http://www.google.com"" , inputting it into the demo main.lua, and then from there it breaks.
When I build on the device I get the event.response "unauthorized."
Unfortunately, I haven't the faintest idea of where to go from here. I'm supposed to add the ability to post scores to twitter to my game... something I had expected to be simple is turning out to waste a lot of my time.
Hi all,
Does anyone know how to post a photo to Twitter?
I checked Twitter api and found there is POST statuses/update_with_media which allows to post a photo to twitter.
My problem is that i don't know how to add param to the url in corona. If anyone know or successfully post a photo to Twitter, please share.
Your idea will be much more appreciated. :-)
We just released a Twitter library for Corona SDK that does all the dirty work for you.
It can upload pictures, and it's REALLY simple to use.
With our lib, a tweet in your Corona code will look like this :
1 | twitterLib.tweet( "Hello world", "local/path/to/image.jpg" ) |
Check it out: http://silverthorax.com/libs/twitter-facade






I'm unable to get this to work, I've tried it with Readability's API as well as Twitter, with no luck :(
any suggestions?
