facebook graph api - How to get friendlists of the not current session user? -


i read facebook api

https://developers.facebook.com/docs/reference/api/user/

i trying request friendlists using not current session follows:

1. access token via app

https://graph.facebook.com/oauth/access_token? client_id=your_app_id&client_secret=your_app_secret&grant_type=client_credentials

i surely obtained access token. shown below:

access_token=1234567890|-abcdefghijkl

2. request friendlists using access token.

https://graph.facebook.com/1023456789/friendlists?access_token=1234567890|-abcdefghijkl

but, following error message has been received.

{    "error": {       "message": "a user access token required request resource.",       "type": "oauthexception",       "code": 102    } }

id not current user session. know, if using current user session. can friends lists in without problem.

https://graph.facebook.com/me/friends?access_token=1234567890|-abcdefghijkl

my question can summarized follows:

how friends list using user id not current session? think must obtain friendlists permission when accesstoken. if right. how do that?

assuming access token got 1 where, user redirected fb login page , redirected application read along.

the documentation can bit confusing. this page states that:

when user logs app , request no additional permissions, app have access user's public profile , friend list.

without digging documentation permission list, 1 might think when read_friendlists added scope user's friend list available, won't be. this page indicated reading facebook user's friend list requires extended permission.

so need add read_friendlists 1 of scope. here's sample request:

https://www.facebook.com/dialog/oauth?type=user_agent     &client_id=your_fb_appid     &redirect_uri=your_domain     &scope=read_friendlists

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
