Does anyone know why? What is the solution?

推荐答案

通过 Facebook的平台更新：

更改会话重定向行为

Change in Session Redirect Behavior

本周，当
此字段留空时，我们开始向redirect_uri添加片段＃____ = ____。请确保您的应用程序可以处理此
行为。

This week, we started adding a fragment #____=____ to the redirect_uri when this field is left blank. Please ensure that your app can handle this behavior.

为了防止这种情况，请在登录URL请求中设置redirect_uri，如所以:(使用Facebook php-sdk）

To prevent this, set the redirect_uri in your login url request like so: (using Facebook php-sdk)

$facebook->getLoginUrl(array('redirect_uri' => $_SERVER['SCRIPT_URI'],'scope' => 'user_about_me'));

更新

以上正如文档所述，以解决这个问题。但是，Facebook的文档化解决方案无效。请考虑对 Facebook平台更新博客文章发表评论，并按照这个bug 得到一个更好的答案。在此之前，将以下内容添加到头标中以解决此问题：

The above is exactly as the documentation says to fix this. However, Facebook's documented solution does not work. Please consider leaving a comment on the Facebook Platform Updates blog post and follow this bug to get a better answer. Until then, add the following to your head tag to resolve this issue:

<script type="text/javascript">
    if (window.location.hash && window.location.hash == '#_=_') {
        window.location.hash = '';
    }
</script>

或更详细的选择（谢谢 niftylettuce ）：

Or a more detailed alternative (thanks niftylettuce):

<script type="text/javascript">
    if (window.location.hash && window.location.hash == '#_=_') {
        if (window.history && history.pushState) {
            window.history.pushState("", document.title, window.location.pathname);
        } else {
            // Prevent scrolling by storing the page's current scroll offset
            var scroll = {
                top: document.body.scrollTop,
                left: document.body.scrollLeft
            };
            window.location.hash = '';
            // Restore the scroll offset, should be flicker free
            document.body.scrollTop = scroll.top;
            document.body.scrollLeft = scroll.left;
        }
    }
</script>
