问题描述
我正在尝试在Rails应用中测试Facebook用户的授予权限.
I'm trying to test for granted permissions by Facebook users in a rails app.
这是我检查权限时Facebook返回的内容:
This is what Facebook returns when I check for permissions:
#<HTTParty::Response:0x7f82dc963820 @parsed_response={"data"=>[{"installed"=>1, "status_update"=>1, "photo_upload"=>1, "video_upload"=>1, "offline_access"=>1, "email"=>1, "create_note"=>1, "share_item"=>1, "publish_stream"=>1, "publish_actions"=>1, "user_likes"=>1, "user_about_me"=>1}]}
因此,我想检查是否存在publish_actions
权限.这是我尝试过的:
So, I want to check for the publish_actions
permission, which, is there. This is what I've tried:
def self.to_facebook(user, chapter, action)
auth = Authorization.find_by_user_id(user)
if self.user_has_granted_publish_actions?(auth)
ret = HTTParty.post('https://graph.facebook.com/' + "#{auth.uid}" + '/bookstore:' + "#{action}" + '?access_token=' + "#{auth.token}" + '&chapter=http://samples.ogp.me/1403776044881')
else
message = URI.escape('Test message')
ret = HTTParty.post('https://graph.facebook.com/' + "#{auth.uid}" + '/feed' + '?access_token=' + "#{auth.token}" + '&message=' + "#{message}")
end
end
def self.user_has_granted_publish_actions?(authorization)
auth = Authorization.find(authorization)
ret = HTTParty.get('https://graph.facebook.com/' + "#{auth.uid}" + '/permissions' + '?access_token=' + "#{auth.token}")
return true if ret.parsed_response['data'].include?('publish_actions') && ret.parsed_response['data']['publish_actions'] == 1
end
我认为问题可能出在这行上,因为似乎方法返回false并发布了默认消息.
I think the problem is probably on this line because it seems that method is returning false and the default message is being posted.
return true if ret.parsed_response['data'].include?('publish_actions') && ret.parsed_response['data']['publish_actions'] == 1
对我在做什么错有任何想法吗?
Any thoughts on what I'm doing wrong?
推荐答案
发现了问题.这有效:
return true if ret.parsed_response['data'][0].has_key?('publish_actions') && ret.parsed_response['data'][0]['publish_actions'] == 1
