Demonstrates how to retrieve information about the current Facebook user. This is the most basic thing to get working first (after obtaining an access token). Tcl

load ./chilkat.dll

set success 0

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

# This example assumes we previously obtained an access token
set oauth2 [new_CkOAuth2]

CkOAuth2_put_AccessToken $oauth2 "FACEBOOK-ACCESS-TOKEN"

set rest [new_CkRest]

# Connect to Facebook and send the following GET request:

# GET /v2.7/me HTTP/1.1
# Host: graph.facebook.com
set bAutoReconnect 1
set success [CkRest_Connect $rest "graph.facebook.com" 443 1 $bAutoReconnect]
if {$success != 1} then {
    puts [CkRest_lastErrorText $rest]
    delete_CkOAuth2 $oauth2
    delete_CkRest $rest
    exit

# Provide the authentication credentials (i.e. the access key)
CkRest_SetAuthOAuth2 $rest $oauth2

    delete_CkRest $rest
    exit

# The responseJson looks like this:
