下面是我正在尝试的代码

    define("FB_WEB_APP_ID","********");
    define("FB_WEB_SECRET","********");
    define("FB_WEB_REDIRECT_URI","<< redirect url >>");
    $GLOBALS["all_user_dir_path"]="/var/www/proj/web/video/user_videos/";
     define("FB_WEB_SCOPE","user_friends,email,public_profile,user_hometown,user_location,user_photos,user_videos,publish_actions,read_friendlists,publish_stream,offline_access");
    define("FB_WEB_RESPONSE_TYPE","code%20token");

    $GLOBALS["fb_app_creds"]=array();
    $GLOBALS["fb_app_creds"]['appId']= FB_WEB_APP_ID;
