How to get values from facebook.

somezombiegm

Hey guys!

I'm a real noob here and I honestly don't know how the facebook events work. I've just implemented ar2rsawseen's plugin and succesfully tested his example (after hours of suffering).

I don't understand the Gideros Documentation. For example on http://docs.giderosmobile.com/reference/plugin/Facebook/graphRequest, it says that if I put "me" as a parameter

facebook:graphRequest("me")

I get the data of the currently logged user. Like id, username, name, gender, etc. But how do I implement that? Do the values get stored on a table? For example, If I want to print my name, would this do?

user = facebook:graphRequest("me") print("Hello:",user.name)

tkhnoman

Use event handler to handle graph request.

facebook:addEventListener(Event.REQUEST_COMPLETE, function(e) -- print("request complete:", e.type) -- print( ) -- for k,v in pairs(e) do print(k,v) end   if e.type == "me" then if e.response then local tableGet = Json.Decode(e.response) -- this is from other function, not native API   if tableGet then -- print(tableGet.id) end end end end)   facebook:addEventListener(Event.REQUEST_ERROR, function(e) print("request error:", e.type, e.error) end)

Thanks a lot @tkhnoman, I added the event to the example and now I have this

require "facebook"   facebook:addEventListener(Event.LOGIN_COMPLETE, function() --print("login successful") facebook:extendAccessTokenIfNeeded() end)   facebook:setAppId("352852401492555"); facebook:authorize();   local text = TextField.new(nil, "post to wall") text:setScale(3) text:setPosition(10, 150) stage:addChild(text) text:addEventListener(Event.TOUCHES_BEGIN, function(e) if text:hitTestPoint(e.touch.x, e.touch.y) and facebook:isSessionValid() then facebook:dialog("feed", { link = "<a href="http://giderosmobile.com"" rel="nofollow">http://giderosmobile.com"</a>, picture = "<a href="http://www.giderosmobile.com/wp-content/uploads/2012/06/gideros-mobile-small.png"" rel="nofollow">http://www.giderosmobile.com/wp-content/uploads/2012/06/gideros-mobile-small.png"</a>, name = "GiderosMobile.com", caption = "Awesome tool", description = "Check out this awesome product" }) end end)     local text2 = TextField.new(nil, "Make api request") text2:setScale(3) text2:setPosition(10, 350) stage:addChild(text2) text2:addEventListener(Event.TOUCHES_BEGIN, function(e) if text2:hitTestPoint(e.touch.x, e.touch.y) and facebook:isSessionValid() then facebook:graphRequest("me") end end)   local text3 = TextField.new(nil, "Hello user") text3:setScale(3) text3:setPosition(10, 450) stage:addChild(text3)   facebook:addEventListener(Event.REQUEST_COMPLETE, function(e) -- print(e.response)   -- print("request complete:", e.type) -- print( ) -- for k,v in pairs(e) do print(k,v) end text3:setText("test 1") if e.type == "me" then text3:setText("test 2") if e.response then text3:setText("test 3") local tableGet = Json.Decode(e.response) -- this is from other function, not native API   if tableGet then text3:setText("Hello".." "..tableGet.name.." aka "..tableGet.username) -- print(tableGet.id) end end end end)   facebook:addEventListener(Event.REQUEST_ERROR, function(e) --print(e.errorDescription) end)

So what I'm testing is to write on the textfield something like: Hello Oscar aka somezombie. But the code doesn't get to that part. text3 only shows "test 1". Any ideas why?

Oops...
I totally forgot about this.

Please us this :

The facebook at Gideros standard API might be deprecated. (I'm using 2014.01, so i don't know about the recent one.)

If you need to create a player : http://docs.giderosmobile.com/deployment.html

(Also, uncomment -- for k,v in pairs(e) do print(k,v) end to get the table e's content)

somezombiegm

Thanks I'll try it out and come back to you...

@tkhnoman First of all, I forgot to say that I'm testing the Facebook plugin on Eclipse . And since I'm testing it there, all the prints don't work there, If I want to print something I have to add it to a textfield. Also I'm testing it on a device and the emulator.

And when you say

Please us this :
http://giderosmobile.com/labs/facebook

Do you mean the code? I don't see any facebook:graphRequest or any way to obtain the logged users data .

SinisterSoft

you can get the users, their data, images,etc all with the lab lib

@somezombiegm

1. http://giderosmobile.com/labs/facebook
At here, you need to login to view.
After that, refresh that page, and download would appear.

2. Then you need to proceed adding Facebook to your game,
-see install.html inside it to know how to add it

3. Facebook is a little different with other plugin, it uses Library.
https://developers.facebook.com/docs/android/getting-started/

Also, you need hashkey:
https://developers.facebook.com/docs/android/getting-started/#release-key-hash

-!! If the app said hashcheck failure, then simply just copy what in the eclipse log by searching "hash", get the hash value and add it to the Android hashkey. Do not remove the old one. This probably only happen after you wrongly doing the things on developer's device.


4. Before you deploy the game with eclipse,
-delete asset folder inside asset Folder
By doing that, you created a player, which work like the real app (considering plug-in, or bundle if you export)

@tkhnoman

It took me a while but now I have my Gideros player for Android with FB plugin, thanks to this link you gave me: http://docs.giderosmobile.com/deployment.html

No I can test this code on my device

facebook:graphRequest("me")   facebook:addEventListener(Event.REQUEST_COMPLETE, function(e) --print(e.response) print("request complete:", e.type) print( ) for k,v in pairs(e) do print(k,v) end if e.type == "me" then if e.response then local tableGet = Json.Decode(e.response) -- this is from other function, not native API   if tableGet then print(tableGet.id) end end end end)

Which prints on my output:

request complete: nil

__target table: 0x623c0a00
__type requestComplete
__userdata userdata: 0x623c1640
response {"id":"580168967","education":[{"school":{"id":"106383376064698","name":"Colegio los Pirineos Don Bosco"}, etc, etc, etc.

I could print my data, which is nice :-bd I can work with that. However, e.type is always nil. I'm not sure if I understood what you said before; If I download the new Gideros 2014.10, will it support e.type?

I'm using Gideros 2014.01
I used this SDK: https://developers.facebook.com/docs/android
And followed this steps: https://developers.facebook.com/docs/android/getting-started

tkhnoman

I'm also using 2014.01.

Probably, the difference here is that i'm using this :
http://giderosmobile.com/labs/facebook

The API is a little bit different, but it works better.

somezombiegm

@tkhnoman I'm sorry I still don't undertand what do you mean by that...

tkhnoman

In that page, you can see Login to view button at the left.
Just log in, and go to that page again, it would turn into Download.
And you would get newer plugin for Android at that

somezombiegm

@tkhnoman Instead of Download I see "Upgrade to Get it". Since I have a free licence I can't have it I guess.

somezombiegm

Sorry for bothering you so much, but when I comment

--if e.type == "me" then

I get an error on

local tableGet = Json.Decode(e.response)

main.lua:55: attempt to index global 'Json' (a nil value)

tkhnoman

Hmm.. I wonder about that.
I though they open up all Labs for all member.
Let's just mention @ar2rsawseen


That Json is not native API.
There are many json parser on lua that you can get online.

---
There are also native json, but i never use that. Probably worth to try :

require "json"   local tableGet = json.decode(e.response)

Is this run for you?

somezombiegm

1. Ok

2. I added json.lua and now works fine. Thanks

ar2rsawseen

All plugins that were in Labs now available on Github:
https://github.com/gideros/giderosplugins


and yes e.type is only in new facebook plugin version, which uses Facebook SDK 3+, the old one was using second FB sdk, which was deprecated quite a while ago.
