未启用安全浏览的用户无法看到我的Facebook应用

Question

I have created a simple FB app using PHP. To meet the new regulation imposed by FB, I have already installed SSL certificates on my server. However, the app can only be seen when secure browsing is enabled, else it will show only a blank canvas.

I know secure browsing is not enabled by default on FB. Is there any reason why this is happening?

Answer 1

You can forward users to use HTTPS when you see HTTP in the Request URI .

// forced HTTPS mechanism used in heroku Facebook App
if (substr(AppInfo::getUrl(), 0, 8) != 'https://' && $_SERVER['REMOTE_ADDR'] != '127.0.0.1') {
    header('Location: https://'. $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
    exit();
}

Answer 2

In your login url make sure you gave url http:// not https://

     $loginUrl=$facebook->getLoginUrl(array(
    'scope'         => 'scopes',
    'redirect_uri'  =>'http://apps.facebook.com/YOURAPPNAMESPACE/'
      ));

Answer 3

在开发人员页面上检查应用程序设置，您可能在Canvas URL设置了HTTPS URL Canvas URL
