laravel 如何显示正确的html与mews/净化器?

在laravel 8中使用mews/purifier 3.4,我在我的blade文件中写了表定义的内容:

<div class="news-view-content">
    {!! \Purifier::clean($news->content) !!}
</div>

字符串
在我的浏览器中,我看到没有表定义的html代码:

<p>2014 b</p>
<p>1112131421222324</p>

<p>&nbsp;</p>


如果不使用\Purifier::clean方法,我会看到带有表定义的html代码:

<div class="news-view-content">
    <p>2014 b</p>
    <figure class="table">
        <table>
            <tbody>
            <tr>
                <td>11</td>
                <td>12</td>
                <td>13</td>
                <td>14</td>
            </tr>
            <tr>
                <td>21</td>
                <td>22</td>
                <td>23</td>
                <td>24</td>
            </tr>
            </tbody>
        </table>
    </figure>
    <p>&nbsp;</p>

</div>


我打开了config/purifier.php文件,在custom_definition=>elements块下添加了一行表格规则:

<?php

    'encoding'           => 'UTF-8',
    'finalize'           => true,

但是在清除该高速缓存后,我仍然看到html代码:

<div class="news-view-content">
    <p>2014 b</p>
    1112131421222324<p>&nbsp;</p>
</div>


我应该使用什么规则来渲染表格html?

这里主要的事情是你的HTML.Allowed定义目前是这样的:

div,b,strong,i,em,u,a[href|title],ul,ol,li,p[style],br,span[style],img[width|height|alt|src]

字符串
缺少,table,tbody,tr,td,figure
值得注意的是,HTML Purifier并不支持figure,因此即使您将其添加到allowlist,如果没有自定义定义定义,它仍然会被剥离,因为HTML Purifier只允许它知道的东西(出于安全原因)。
值得庆幸的是,figure已经在你的custom_definition => elements中了:

// http://developers.whatwg.org/grouping-content.html
                ['figure', 'Block', 'Optional: (figcaption, Flow) | (Flow, figcaption) | Flow', 'Common'],


所以一旦你把它添加到allowlist,它就应该工作了。
