Facebook PHP SDK get access token using php
I am using the following code to post to Facebook:
require('facebook.php');
$fb = new Facebook(array('appId' => 'MY APP ID','secret' => 'MY APP SECRET','cookie' => true));
$result = false;
$feed_dir = '/401868882779/feed/'; //to the开发者_如何转开发 UID you want to send to
$acToken = "MY ACCESS TOKEN";
$url = 'URL';
$link = $url . 'event.php?id=' . $id;
if (isset($picture))
{
$picture = $url . 'uploads/' . $picture;
}
else
{
$picture = $url . 'images/blank100x70.png';
}
$msg_body = array('access_token' => $acToken,'name' => $noe_unsecured,'message' => $link,'link' => $link,'description' => $description_unsecured,'picture' => $picture);
try
{
$result = $fb->api($feed_dir, 'post', $msg_body);
}
catch (Exception $e)
{
$err_str = $e->getMessage();
}
but I need to update the access token manually every time it changes. I am sure there's solution but I cant find it.. I tried lots of scripts and nothing worked.
It is possible.
Check: http://developers.facebook.com/docs/reference/php/facebook-setAccessToken/
Depending on when you perform the wall post, you might need to request the offline_access permission. This will convert your access_token into a format that does not expire so there would be no need to refresh the token.
A simple solution...remove the access_token
!
You simply don't need it as long as you got the publish_stream
permission!
I believe there are multiple methods to do this:
- you can use the method already provided in the PHP SDK getAccessToken
which returns the current access token being used by the sdk instance, more info at this url.
- However you need not use an access token to call the api()
method, once you ask the user for the publish_stream permission, as already mentioned by @ifaour. Hence you can do something like this example, scroll to the subheading Post a link to a User's wall using the Graph API.
- Then, you have another three options
i) either get a new access token using the method here, if you are posting when the user is currently using your app, otherwise you can try the next 2 options
ii) get offline access
iii) i'm not sure of this, but you might want to try with an app access token which can be obtained this way.
