Hello, I created an app with angularJS, I get the following message:
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4435' is therefore not allowed access.

Then I tried the following solution:
in ROOT\components\com_jbackend\views\request\view.html.php" i added
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET, PUT, DELETE, OPTIONS');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization");

Works on the first request, the next sequinte get the message:

XMLHttpRequest cannot load rachataxi.widesys.net.br/rest/post/user/updatelatlngorigin?api_key=HT83ZL860MC0V6GPNEFB. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4435' is therefore not allowed access. The response had HTTP status code 500.

I'm almost no sleep, please help me.

Thanks for the feedback, look what I found out about the second error:
On the browser, login with step 1 and update and localization with the 2nd step ..

STEP 1º - rachataxi.widesys.net.br/rest/post/user/login?username=a@a.com&password=admin&api_key=HT83ZL860MC0V6GPNEFB

STEP 2º - rachataxi.widesys.net.br/rest/post/user/login?username=a@a.com&password=admin&api_key=HT83ZL860MC0V6GPNEFB

Will work perfectly, but when I do the same steps for the webapp "jQuery or AngularJS POST", I found that the Step 2 failure "foreign key constraint fails" by the user is not logged into the server, ask:

All and any operation that is done, I need to always login the user?

Thanks

Just complementing, I made two videos explaining the 2 steps:

STEP 1 - Test with a browser, the user keeps logged and can do other operations.
rachataxi.widesys.net.br/images/Untitled%20Screencast%20(4).webm

STEP 2 - Test with webapp, you DO NOT Keep logged in.
rachataxi.widesys.net.br/images/Untitled%20Screencast%20(5).webm

Any idea why user is not logged in when WEBAPP use?

Thanks

Hello, thanks for the reply, it was good.
I left a question of how to send the session cookie data in joomla google groups, if you have an example and can pass me.

PS: In login I'm already returning session_name, session_id, cookie_value, now do not know how to send them joomla.

If you can help me thank you very much.
