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?

删除“#_=_”(PHP)的最简单和干净的解决方案:

用“echo(”Location .php)代替“header("Location: xxx.php");"Href = 'xxx.php';");"

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>

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。

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>";        
}

不知道他们为什么这样做,但是,你可以通过重置页面顶部的哈希来解决这个问题:

if (window.location.hash == "#_=_")
  window.location.hash = "";

博士TL;

if (window.location.hash === "#_=_"){
    history.replaceState 
        ? history.replaceState(null, null, window.location.href.split("#")[0])
        : window.location.hash = "";
}

完整版本与一步一步的说明

// Test for the ugliness.
if (window.location.hash === "#_=_"){

    // Check if the browser supports history.replaceState.
    if (history.replaceState) {

        // Keep the exact URL up to the hash.
        var cleanHref = window.location.href.split("#")[0];

        // Replace the URL in the address bar without messing with the back button.
        history.replaceState(null, null, cleanHref);

    } else {

        // Well, you're on an old browser, we can get rid of the _=_ but not the #.
        window.location.hash = "";

    }

}

循序渐进:

We'll only get into the code block if the fragment is #_=_. Check if the browser supports the HTML5 window.replaceState method. Clean the URL by splitting on # and taking only the first part. Tell history to replace the current page state with the clean URL. This modifies the current history entry instead of creating a new one. What this means is the back and forward buttons will work just the way you want. ;-) If the browser does not support the awesome HTML 5 history methods then just clean up the URL as best you can by setting the hash to empty string. This is a poor fallback because it still leaves a trailing hash (example.com/#) and also it adds a history entry, so the back button will take you back to #_-_.
