如何让Omniauth使用弹出窗口？

Question

如果你在现有窗口中打开Omniauth,默认情况下效果很好,但是不确定它在弹出上下文中是如何工作的,你通过javascript处理很大一部分交互

Answer 1

var newwindow;
function login(provider_url, width, height) {
  var screenX     = typeof window.screenX != 'undefined' ? window.screenX : window.screenLeft,
      screenY     = typeof window.screenY != 'undefined' ? window.screenY : window.screenTop,
      outerWidth  = typeof window.outerWidth != 'undefined' ? window.outerWidth : document.body.clientWidth,
      outerHeight = typeof window.outerHeight != 'undefined' ? window.outerHeight : (document.body.clientHeight - 22),
      left        = parseInt(screenX + ((outerWidth - width) / 2), 10),
      top         = parseInt(screenY + ((outerHeight - height) / 2.5), 10),
      features    = ('width=' + width + ',height=' + height + ',left=' + left + ',top=' + top);

      newwindow = window.open(provider_url, 'Login', features);

  if (window.focus)
    newwindow.focus();

  return false;
}

将provider_url替换为'/ auth/facebook'或'/ auth/twitter'应该有效.

在你的回调网址,

<script type="text/javascript">
  window.opener.location = '<%= @redirect_to %>';
  window.close();
</script>

您可以使用@redirect_to指向要将父窗口刷新到的页面随意刷新页面.
