check for extended permissions with new facebook javascript sdk
提问by choise
is there a way to check in my application (canvas) if the user has extended permission (for example "stream.publish")?
如果用户具有扩展权限（例如“stream.publish”），有没有办法检查我的应用程序（画布）？
i only can find a solution for the old sdk.
我只能找到旧sdk的解决方案。
thanks!
谢谢！

Update at the end of 2011:
2011年底更新：
FB.api('/me/permissions', function (response) {
console.log(response);
} );
console output:
控制台输出：
{
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
此解决方案已于 2011 年底弃用，请使用上面标记为已接受的答案
found a solution myself
自己找到了解决办法
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
这将检查publish_stream和read_stream
example use:
示例使用：
check_ext_perm(response.session, function(isworking) {
if(isworking) {
// post something to wall
} else {
// ask for login
}
});

FB.ui({
method: '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).');
}
});

Generalized choise's function,
广义选择函数，
function 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.
如果用户拥有所有权限，则使用 true 调用回调，否则使用 false 调用回调。

The responses here that use FB.Data.queryare to be avoided as this point, as Facebook has deprecated FB.Data.queryentirely. The FB.api(/me/permissions ...) solution seems best.
在FB.Data.query这一点上应避免使用此处的响应，因为 Facebook 已FB.Data.query完全弃用。该FB.api（/ ME /权限...）解决方案似乎是最好的。

You can also get permissions back from FB.login:
您还可以从 FB.login 获取权限：
FB.login(function(response) {
// handle the response
}, {
scope: 'publish_actions',
return_scopes: true
});
