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?

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

我看不出这个问题与facebook AJAX有什么关系。事实上,禁用JavaScript和完全基于重定向的登录也会出现这个问题。

一个与facebook交换的例子:

1. GET <https://www.facebook.com/dialog/oauth?client_id=MY_APP_ID&scope=email&redirect_uri=MY_REDIRECT_URL> RESPONSE 302 Found Location: <https://www.facebook.com/connect/uiserver.php?[...]>  
2. GET <https://www.facebook.com/connect/uiserver.php?[...]> RESPONSE 302 Found MY_REDIRECT_URL?code=FB_CODE#_  
3. GET MY_REDIRECT_URL?code=FB_CODE#_  

我也只在火狐浏览器上遇到过这种情况。

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
  }
})

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>";        
}

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>
