Facebook回调附加“#_=_”到返回URL

Facebook回调已经开始追加#_=_哈希下划线返回URL

有人知道为什么吗?解决方案是什么?

当前回答

主要恼人的，特别是应用程序解析URI，而不只是读取$_GET…这是我拼凑出来的……享受吧!

<html xmlns:fb='http://www.facebook.com/2008/fbml'>
<head>
        <script type="text/javascript">
        // Get rid of the Facebook residue hash in the URI
        // Must be done in JS cuz hash only exists client-side
        // IE and Chrome version of the hack
        if (String(window.location.hash).substring(0,1) == "#") {
                window.location.hash = "";
                window.location.href=window.location.href.slice(0, -1);
                }
        // Firefox version of the hack
        if (String(location.hash).substring(0,1) == "#") {
                location.hash = "";
                location.href=location.href.substring(0,location.href.length-3);
                }
        </script>
</head>
<body>
URI should be clean
</body>
</html>

将此添加到我的重定向页面解决了我的问题…

if (window.location.href.indexOf('#_=_') > 0) {
    window.location = window.location.href.replace(/#.*/, '');
}

如果你使用vue-router，你可以添加到路由列表:

{
  path: '/_=_',
  redirect: '/', // <-- or other default route
},

我知道这个回复晚了，但如果您正在使用passportjs，您可能想看到这个。

return (req, res, next) => {
    console.log(req.originalUrl);
    next();
};

我已经编写了这个中间件，并将其应用于表示服务器实例，我得到的原始URL没有“#_=_”。看起来，当我们将passporJS的实例作为中间件应用到服务器实例时，它不接受这些字符，而只在浏览器的地址栏上可见。

通过Facebook平台更新:

更改会话重定向行为本周，我们开始在redirect_uri中添加一个片段#____=____ 该字段为空。请确保您的应用程序可以处理这个问题的行为。

为了防止这种情况，在你的登录url请求中设置redirect_uri(使用Facebook php-sdk)

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

更新

上述内容正是文档中所述的修复此问题的方法。然而，Facebook记录的解决方案并不奏效。请考虑在Facebook平台更新博客上留下评论，并关注这个错误以获得更好的答案。在此之前，将以下内容添加到head标签以解决此问题:

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

或者一个更详细的选择(感谢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>

使用angular和angular ui router，你可以修复这个问题

    app.config(function ($stateProvider, $urlRouterProvider, $locationProvider) {

      // Make a trailing slash optional for all routes
      // - Note: You'll need to specify all urls with a trailing slash if you use this method.
      $urlRouterProvider.rule(function ($injector, $location) {
        /***
        Angular misbehaves when the URL contains a "#_=_" hash.

        From Facebook:
          Change in Session Redirect Behavior
          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.

        Fix:
          http://stackoverflow.com/questions/7131909/facebook-callback-appends-to-return-url#answer-7297873
        ***/
        if ($location.hash() === '_=_'){
          $location.hash(null);
        }

        var path = $location.url();

        // check to see if the path already has a slash where it should be
        if (path[path.length - 1] === '/' || path.indexOf('/?') > -1) {
          return;
        }
        else if (path.indexOf('?') > -1) {
          $location.replace().path(path.replace('?', '/?'));
        }
        else {
          $location.replace().path(path + '/');
        }
      });

      // etc ...
    });
});
