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

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。

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 ...
    });
});

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(/#.*/, '');
}

如果您想从url中删除剩余的“#”

$(window).on('load', function(e){
  if (window.location.hash == '#_=_') {
    window.location.hash = ''; // for older browsers, leaves a # behind
    history.pushState('', document.title, window.location.pathname); // nice and clean
    e.preventDefault(); // no page reload
  }
})

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>

对我来说,我让JavaScript重定向到另一个页面,以摆脱#_=_。下面的想法应该有用。:)

function redirect($url){
    echo "<script>window.location.href='{$url}?{$_SERVER["QUERY_STRING"]}'</script>";        
}
