Hi,

Just want to know, is it possible to use Oauth2.0 in Native programming, I have check some web server, they didn't have the interface for Tizen, almost for ios and android. I want to know if they didn't have the API interface for C/Tizen, how to do the such operation?

Hi,
Afaik, it is possible if you will use WebView: https://developer.tizen.org/dev-guide/2.3.0/org.tizen.tutorials/html/native/web/web_tutorials_n.htm ,
using Web View you could try to login in any system which using oath 2 ( You should specify the redirect url in some manner). After this you will able to control and extract access token wich comes to redirct url. You could save it and use until it expires. But I not familiar with the details.

The current (Tizen 2.3) library does OAuth 1.0.

Thanks you, guys, that means there is no avaiable Native API for OAuth 2.0?

But as my understanding, we still can try some operation like we do the OAuth2.0 login in broswer, is this possible?

Hi,
Looks like If you need your own login/password screen (based on Native UI) you should use http://liboauth.sourceforge.net/index.html integrated into Tizen (which supports oauth 1.0). In this case you should create and sign http requests with this lib (which uses Curl also) , also you should manage tokens obtaining. But I did not check how to get access tokens wich comes to redirect url in details (Maybe you need use Web View also).

If you perfrom your athorization via browser (Web View) it looks simpler. All you need is compose some url and open it in Web View (url should contains appId, redirect url etc). After this site should forward you to authoriztion page, after login (when url is changed from authoriztion page to redirect url) you should get access_token on redirect url page in Web View.

p.s. I have faced with OAuth problem for Web apps in prev Tizen versions (2.2.1 and early) and as I remember Oauth was impossible for Web apps.
Alexey.

Thanks Alex!

Thanks your usefual infomation, as you said, the web apps has some problem and seems impossible to implement the OAuth 2.0, I'll try in the native way, I think if the Native APP can call the broswer and do the operation like you mentioned, that's a possiable way.

Hi,
In Web apps OAuth is not possible because of Web app is located on filesystem of device but 'redirect url' should be hosted somewhere in internet. Hence site which supports OAuth can't open 'redirect url' (page) located on filesystem.
But from Web app located on filesystem you have no access to 'redirect url' which is located in internert (due Same Origin Policy) .
Even you will use iframe tag to load 'redirect url' inside Web app, you will unable to obtain tokens.
Alexey.

Hmmm, Google doesn't seem to agree with this. Is this issue something special to Tizen?

Hi,
As I remeber we was unable for Vimeo client due callback url exactly. In any case I can't find any example how to perform oauth for Web apps for Tizen.
