我正在使用 HTMLPurifier 来转义我网站中的字符。有效地把所有的<
东西都>
变成它应该的样子。我还想在站点内显示代码,但是当使用 将代码放置到站点上时,而不是将和符号呈现为并且它们保持显示为编码的.>
<
<pre><code>...</code></pre>
>
<
<
>
>
我知道该 <pre>
标签旨在显示预先格式化的文本
仅当包装在标签中以使用 JS/JQuery呈现为 ( & ) 时,我将如何安全地转换这些符号 ( >
& )?<
<pre><code>...</code></pre>
<
>
<php 'default' => 'local'
转换成<php 'default' => 'local'
注意:渲染 HTML 标签时不会发生这种情况。我相信这是由 HTMLPurifier 引起的。
HTML 正确呈现为
<div>
...Some code here...
</div>
更新#1:
我在网站上使用 Markdown,我的 HTMLPurifier 配置如下:
<?php
/**
* Ok, glad you are here
* first we get a config instance, and set the settings
* $config = HTMLPurifier_Config::createDefault();
* $config->set('Core.Encoding', $this->config->get('purifier.encoding'));
* $config->set('Cache.SerializerPath', $this->config->get('purifier.cachePath'));
* if ( ! $this->config->get('purifier.finalize')) {
* $config->autoFinalize = false;
* }
* $config->loadArray($this->getConfig());
*
* You must NOT delete the default settings
* anything in settings should be compacted with params that needed to instance HTMLPurifier_Config.
*
* @link http://htmlpurifier.org/live/configdoc/plain.html
*/
return [
'encoding' => 'UTF-8',
'finalize' => true,
'cachePath' => storage_path('app/purifier'),
'cacheFileMode' => 0755,
'settings' => [
'default' => [

],
],
];
This is the method I'm using to call the Purifier
public function store(Request $request)
{
//Validate the data
$this->validate($request, array(
'title' => 'required|max:255',
'slug' => 'required|alpha_dash|min:5|max:255|unique:posts,slug',
'category_id' =>'required|integer',
'body' => 'required'
));
//Store in the database
$post = new Post;
$post->title = $request->title;
$post->slug = $request->slug;
$post->category_id = $request->category_id;
$post->body = Purifier::clean($request->body, "youtube");
$post->save();
$post->tags()->sync($request->tags, false);
Session::flash('success', 'AWESOMESAUCE! Your post was saved successfully!');
//redirect to another page
return redirect()->route('posts.show', $post->id);
}

这个问题导致我搜索以前的代码。问题来自 Markdown 解析器,它是Parsedown而不是 Purifier。净化器工作正常。我在下面添加了 Markdown 配置和使用代码:
