Question

我修改了一个内部错误页面，一旦URL被SquidGuard阻止，该页面就会显示给用户。以下是我需要一些帮助的脚本部分：

# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# IE displayed self-page, if them size > 1024
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
function get_error_page($er_code_id, $err_msg='') {
    global $err_code;
    global $cl;
    $str = Array();

    header("HTTP/1.1 " . $err_code[$er_code_id]);
    $str[] = '<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">';
    $str[] = '<html>';
    $str[] = '<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title></title></head>';
    $str[] = '<body style="background-color:#FFFFFF; font-family:verdana, arial, sans serif;">';

    $str[] = '<div style="padding:5px; background-color:#FFFFFF; text-align:center; font-weight:bold; font-family:verdana,arial,sans serif; color:#2F93D1; font-size:70%;"> <p>';
      if ($cl['n'])        $str[] = "Your Node Name: {$cl['n']} </p><p> ";
      if ($cl['a'])        $str[] = "Your Node IP: {$cl['a']} </p><p> ";
      if ($cl['i'])        $str[] = "Node User: {$cl['i']} </p><p> ";
      if ($cl['s'])        $str[] = "Group: {$cl['s']} </p><p> ";
      if ($cl['t'])        $str[] = "Blacklist Category: {$cl['t']} ";
    $str[] = '</p></div><div style="background-color:#FFFFFF; text-align:center; padding:20px;">';
    $str[] = '<p><img style="padding-top:20px;display: block;margin: 0px auto" src="https://lh4.googleusercontent.com/_aRy3rhrUl64/TaOzVHF01fI/AAAAAAAACVw/H__Us1P5ghc/s800/Untitled.jpg" alt="geblockt"></p></div></div>';
    $str[] = '<div style="padding:20px; margin-top:20px; background-color:#FFFFFF; text-align:center; color:#000000; font-family:verdana, arial, sans serif; font-size:80%;">';
            if ($err_msg) $str[] = '<p style="font-weight:bold; font-size:150%;"> '. $err_msg.' </p>';
            if ($cl['u']) $str[] = "<p><strong>URL: {$cl['u']}</strong></p>";
    $str[] = '<p>Because of access restrictions, your request to the above address is not allowed. </p>
    <p>Please contact <a href="mailto:firewall_support@iuass.org?subject=[HELP IS NEEDED HERE]&body=Please unblock this URL, thanks">IUASS firewall support</a> if you are of the opinion that this is not correct.</p><p>';
    $str[] = '</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p><img src="http://iuass.org/system/cms/themes/default/img/logo.gif" alt="geblockt" width="315" height="44" style="padding-top:20px;display: block;margin: 0px auto"></p></div></div>';
    $str[] = '<div style="width:70%; margin:20px auto; background-color:#FFFFFF; text-align:center; color:#000000; font-size:60%; font-family:verdana,arial,sans serif;">Web Filtering by <a style="color:#000000;">IUASS Firewall implementing pfSense with Squid and SquidGuard</div></div>';
    $str[] = "</body>";
    $str[] = "</html>";

    return implode("\n", $str);
}

我需要做的是将阻止的网址添加到

中的mailto主题

<a href="mailto:firewall_support@iuass.org?subject=[HELP IS NEEDED HERE]&body=Please unblock this URL, thanks">

据我了解，url由{$ cl ['u']}指针引用。如果我在“？subject =”之后添加它，则由于语法错误而无效。因此，有没有办法通过html或php或任何其他脚本，这将使用户一旦点击firewall_support@iuass.org链接打开一个新的电子邮件消息，其中主题字段已填写与任务中的网址？

对此方面的任何帮助表示高度赞赏。

提前致谢。

Answer 1

怎么样：

<?php echo "<a href='mailto:firewall_support@iuass.org?subject=" . $cl['u'] . "&body=Please unblock this URL, thanks'" ?>

这将创建一个超链接，其中包含您提到的mailto URI，插入$ cl ['u']的内容。

Answer 2

你有没有试过像：

if ($cl['u']) $str[] = "<p>Because of access restrictions, your request to the above address is not allowed. </p><p>Please contact <a href=\"mailto:firewall_support@iuass.org?subject={$cl['u']}&body=Please unblock this URL, thanks\">IUASS firewall support</a> if you are of the opinion that this is not correct.</p>";

它总是有用于粘贴代码，例如在pastebin上，以便我们可以查看它，特别是在语法错误的情况下。

此外请注意，如果你按照我建议的简单方式进行操作会遇到麻烦，因为网址会包含像＆amp;这样的字符。您将不得不更换所有出现的＆amp;首先是他们的好处。
