Conclusion : en comparaison de l’API Twitter, l’API linkedin semble moins bien document\u00e9. L’authentification est plus contraignante sans doute parce les donn\u00e9es y sont peut-\u00eatre plus sensibles sur cette plate-forme professionnelle mais enfin on parvient finalement \u00e0 ces fins. La bonne nouvelle c’est que si vous faites les modifications n\u00e9cessaires pour le partage sur Facebook, les donn\u00e9es Open Graph Protocol<\/code> seront utilis\u00e9es \u00e0 l’identique sur Linkedin<\/b><\/p>\n\tUn script d’authentification et de rapatriement des donn\u00e9es de votre compte Linkedin.<\/b><\/p>\n\r\n\t <?php\r\n \/\/ Change these\r\n \/\/ define('API_KEY', 'YOUR_API_KEY_HERE' );\r\n \/\/ define('API_SECRET', 'YOUR_API_SECRET_HERE' );\r\n \/* To change with your own credentials *\/\r\n define('API_KEY', 'msqi8kmf9dy4' );\r\n define('API_SECRET', 'RP71sq5fGWwLMbsN' );\r\n\r\n\r\n\r\n define('REDIRECT_URI', 'http:\/\/' . $_SERVER['SERVER_NAME'] . $_SERVER['SCRIPT_NAME']);\r\n define('SCOPE', 'r_fullprofile r_emailaddress rw_nus' );\r\n\r\n \/\/ You'll probably use a database\r\n session_name('linkedin');\r\n session_start();\r\n\r\n \/\/ OAuth 2 Control Flow\r\n if (isset($_GET['error'])) {\r\n \/\/ LinkedIn returned an error\r\n print $_GET['error'] .
