is there a way to check in my application (canvas) if the user has extended permission (for example "stream.publish")?
i only can find a solution for the old sdk.
thanks!

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
Update at the end of 2011:
ReplyDeleteFB.api('/me/permissions', function (response) {
console.log(response);
} );
console output:
{
data: [
{
create_note: 1,
installed: 1,
photo_upload: 1,
publish_stream: 1,
share_item: 1,
status_update: 1,
video_upload: 1,
}
]
}
this solution is deprecated at the end of 2011, please use the answer that is marked as accepted above
ReplyDeletefound a solution myself
function check_ext_perm(session,callback) {
var query = FB.Data.query('select publish_stream,read_stream from permissions where uid={0}', session["uid"]);
query.wait(function(rows) {
if(rows[0].publish_stream == 1 && rows[0].read_stream == 1) {
callback(true);
} else {
callback(false);
}
});
};
this will check for publish_streamand read_stream
example use:
check_ext_perm(response.session, function(isworking) {
if(isworking) {
// post something to wall
} else {
// ask for login
}
});
Generalized choise's function,
ReplyDeletefunction check_permissions (permissions, uid, cb) {
FB.Data
.query('select {0} from permissions where uid={1}', permissions, uid)
.wait(function (res) {
if (!res || res.length < 1) return cb(false);
var row = res[0];
var aperm = permissions.split(',');
for (var i = 0; i < aperm.length; i++) {
if (row[aperm[i]] != 1) return cb(false);
}
return cb(true);
});
}
Calls the callback with true if the user has all of the permissions, otherwise calls the callback with false.
The responses here that use FB.Data.query are to be avoided as this point, as Facebook has deprecated FB.Data.query entirely. The FB.api(/me/permissions ...) solution seems best.
ReplyDeleteFB.ui({
ReplyDeletemethod: 'permissions.request',
perms: 'user_website',
display: 'popup'
},function(response) {
alert(response.toSource());
if (response && response.perms) {
alert('Permissions granted: '+response.perms);
} else if (!response.perms){
alert('User did not authorize permission(s).');
}
});
