Lua - Uploading to Pastebin - api

Question

Note that this is Roblox's version of lua.
I want to upload a table to Pastebin. Here is what I have for Pastebin.
h = game:GetService'HttpService'
JSON = h:JSONEncode(ImgScript) --ImgScript is a table formatted like {{x,y,z}, {x,y,z}, {x,y,z}, etc.}
h:PostAsync('http://pastebin.com/api/api_post.php','&api_dev_key=CensoredDevKey&api_option=paste&api_paste_code=' .. JSON)
This doesn't work, and I can't seem to figure out why.
EDIT:
I also tried this and it didn't work.
h = game:GetService'HttpService'
api_params = {
["api_dev_key"] = "CensoredDevKey",
["api_option"] = "paste",
["api_paste_code"] = ImgScript
}
api_params = h:JSONEncode(api_params)
h:PostAsync('http://www.pastebin.com/api/api_post.php', api_params)

I also tried this and it didn't work:
h = game:GetService'HttpService'
JSON = h:JSONEncode(ImgScript) --ImgScript is a table formatted like {{x,y,z}, {x,y,z}, {x,y,z}, etc.}
data = h:UrlEncode('&api_dev_key=CensoredDevKey&api_option=paste&api_paste_code=' .. JSON)
h:PostAsync('http://pastebin.com/api/api_post.php', data)

Answer 1

Try the following:
h = game:GetService'HttpService'
pasteData = h:UrlEncode( h:JSONEncode(ImgScript) )
h:PostAsync(
'http://pastebin.com/api/api_post.php',
'api_dev_key=CensoredDevKey&api_option=paste&api_paste_code=' .. pasteData,
2
)
The last parameter, 2 specifies that the data being sent is Application/Url-Encoded.
I think that this should do the trick. Do inform here if it doesn't.
PS: Where are you receiving the result from this POST request?

Answer 2

So I've finished the code, but sadly, Roblox limits the PostAsync size to 256 bytes so any upload larger than that will be GZIPed (up to 1024kb), which Pastebin doesn't know what to do with.
Anyhow, I've released the code here:
http://www.roblox.com/Pastebin-Upload-item?id=302297532
It is:
--Created by GShocked. PM me if you have questions!
h = game:GetService'HttpService'
api_dev_key = '' --Your Pastebin developer key goes here. Log in first, and then you can find it at pastebin.com/api
api_paste_code = '' --The content of your new paste
api_paste_private = '1' --0 public; 1 unlisted; 2 private
api_paste_name = '' --Name your new paste
api_paste_expire_date = 'N' --N for never expire, 10M for 10 minutes, etc.
api_paste_format = 'lua' --The syntax highlighting
api_user_key = '' --This is generated using the login info
api_paste_name = h:UrlEncode(api_paste_name)
api_paste_code = h:UrlEncode(api_paste_code)
username = '' --Your Pastebin username goes here
password = '' --Your Pastebin password goes here
api_user_key = h:PostAsync(
'http://pastebin.com/api/api_login.php',
'api_dev_key=' .. api_dev_key .. '&api_user_name=' .. username .. '&api_user_password=' .. password,
2
)
print(api_user_key) --DON'T DELETE THIS! IT IS ESSENTIAL FOR THE USER KEY TO BE GENERATED!
h:PostAsync(
'http://pastebin.com/api/api_post.php',
'api_option=paste&api_user_key=' .. api_user_key .. '&api_paste_private=' .. api_paste_private .. '&api_paste_name=' .. api_paste_name .. '&api_paste_expire_date=' .. api_paste_expire_date .. '&api_paste_format=' .. api_paste_format .. '&api_dev_key=' .. api_dev_key .. '&api_paste_code=' .. api_paste_code,
