Need the json lua library (Dkjson)
This library is based on : https://www.dropbox.com/developers/core/
Some examples :
-- Tools
function table.print(tbl, indent)
if not indent then indent = 0 end
for k, v in pairs(tbl) do
local formatting = string.rep(" ", indent) .. k .. ": "
if type(v) == "table" then
print(formatting)
table.print(v, indent+1)
else
print(formatting .. to string(v))
end
end
end
function showResult(data,status,headers)
if data and type(data) == "table" then
table.print(data)
else
print(data)
end
print(status)
table.print(headers)
end
function setup()
-- Create your app in dropbox developer
-- (for the examples, app_key and app_secret is visible vars but in real, you need to hide them with save...Data)
app_key = "..."
app_secret = "..."
-- System for Oauth2 identification
tween.delay(2, function()
DropboxAPI.OAuth2.authorize("code", app_key)
end)
parameter.text("Code")
parameter.text("Submit", function()
if Code == "" then return end
DropboxAPI.OAuth2.token(Code, app_key, app_secret, function(data, status, headers)
-- data is a lua tables like : {"access_token": "ABCDEFG", "token_type": "bearer", "uid": "12345"}
-- save the access_token (and the uid)
end)
-- for use the library, you need just to set DropboxAPI.token with the access token
DropboxAPI.token = read...Data("access_token")
-- example1
DropboxAPI.files.get("dropbox", "Apps/Codea/img.png", function(data)
saveImage("Documents:img", data)
end)
-- example2
DropboxAPI.metadata("dropbox", "Apps/Codea", showResult)
