See more Facebook Examples

Demonstrates how to get the photos that the user has uploaded. Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- This example assumes a previously obtained an access token
local oauth2 = chilkat.OAuth2.new()
oauth2.access_token = "FACEBOOK-ACCESS-TOKEN"

local rest = chilkat.Rest.new()

-- Connect to Facebook.
local success = rest:connect("graph.facebook.com", 443, true, true)
if not success then
    print(rest.last_error_text)
    return
end

-- Provide the authentication credentials (i.e. the access key)
rest:set_auth_oauth2(oauth2)

-- Indicate that we only want the photos the user has personally uploaded.
rest:add_query_param("type", "uploaded")

-- We could limit the number of photos by setting a limit.
rest:add_query_param("limit", "5")

-- Gets the 1st page of photos. (Not the actual image data, but the information about each photo.)
-- See https://developers.facebook.com/docs/graph-api/reference/user/photos/ for more information.
local responseJson = rest:full_request_no_body("GET", "/v2.7/me/photos")
if not rest.last_method_success then
    print(rest.last_error_text)
    return
end

local json = chilkat.JsonObject.new()
json.emit_compact = false
json:load(responseJson)
print(json:emit())

-- A sample JSON response is shown below.
-- This is the code to parse the JSON response.

local dtime = chilkat.DateTime.new()
local bLocalTime = true

local dt = chilkat.DtObj.new()
local i = 0
local numItems = json:size_of_array("data")
while i < numItems do
    json.i = i
    print("--- " .. i)
    local name = json:string_of("data[i].name")
    if json.last_method_success then
        print("name: " .. name)
    end

    print("id: " .. json:string_of("data[i].id"))

    -- We can load the created_time into a CkDateTime...
    dtime:set_from_timestamp(json:string_of("data[i].created_time"))
    dtime:to_dt_obj(bLocalTime, dt)

    print(dt.month .. "/" .. dt.day .. "/" .. dt.year .. "  " .. dt.hour .. ":" .. dt.minute)
    i = i + 1
end

-- We can get the paging information as follows:
print("URL for next page: " .. json:string_of("paging.next"))
print("before cursor: " .. json:string_of("paging.cursors.before"))
print("after cursor: " .. json:string_of("paging.cursors.after"))
