"<h2>防御XSS攻击的一般原理</h2> \n" +
"<p>cleaner是Jsoup的重要功能之一，我们常用它来进行富文本输入中的XSS防御。</p> \n" +
"<p>我们知道，XSS攻击的一般方式是，通过在页面输入中嵌入一段恶意脚本，对输出时的DOM结构进行修改，从而达到执行这段脚本的目的。对于纯文本输入，过滤/转义HTML特殊字符<code>&lt;</code>,<code>&gt;</code>,<code>&quot;</code>,<code>'</code>是行之有效的办法，但是如果本身用户输入的就是一段HTML文本(例如博客文章)，这种方式就不太有效了。这个时候，就是Jsoup大显身手的时候了。</p> \n" +
"<p>在前面，我们已经知道了，Jsoup里怎么将HTML变成一棵DOM树，怎么对DOM树进行遍历，怎么对DOM文档进行输出，那么其实cleaner的实现方式，也能猜出大概了。使用Jsoup进行XSS防御，大致分为三个步骤:</p> \n" +
"<ol> \n" +
" <li><p>将HTML解析为DOM树</p> <p>这一步可以过滤掉一些企图搞破坏的非闭合标签、非正常语法等。例如一些输入，会尝试用<code>&lt;/textarea&gt;</code>闭合当前Tag，然后写入攻击脚本。而根据前面对Jsoup的parser的分析，这种时候，这些非闭合标签会被当做错误并丢弃。</p></li> \n" +
" <li><p>过滤高风险标签/属性/属性值</p> <p>高风险标签是指<code>&lt;script&gt;</code>以及类似标签，对属性/属性值进行过滤是因为某些属性值里也可以写入javascript脚本，例如<code>onclick='alert(&quot;xss!&quot;)'</code>。</p></li> \n" +
" <li><p>重新将DOM树输出为HTML文本</p> <p>DOM树的输出，在前面(Jsoup代码解读之三)已经提到过了。</p></li> \n" +
"</ol> \n" +
"<span id=\"OSC_h2_2\"></span>\n" +
"<h2>Cleaner与Whitelist</h2> \n" +
"<p>对于上述的两个步骤，1、3都已经分别在parser和输出中完成，现在只剩下步骤 2：过滤高风险标签等。</p> \n" +
"<p>Jsoup给出的答案是白名单。下面是<code>Whitelist</code>的部分代码。</p> \n" +
"<pre class=\"brush: java\">public class Whitelist {\n" +
" private Set&lt;TagName&gt; tagNames; // tags allowed, lower case. e.g. [p, br, span]\n" +
" private Map&lt;TagName, Set&lt;AttributeKey&gt;&gt; attributes; // tag -&gt; attribute[]. allowed attributes [href] for a tag.\n" +
" private Map&lt;TagName, Map&lt;AttributeKey, AttributeValue&gt;&gt; enforcedAttributes; // always set these attribute values\n" +
" private Map&lt;TagName, Map&lt;AttributeKey, Set&lt;Protocol&gt;&gt;&gt; protocols; // allowed URL protocols for attributes\n" +
" private boolean preserveRelativeLinks; // option to preserve relative links\n" +
"}</pre> \n" +
"<p>这里定义了标签名/属性名/属性值的白名单。</p> \n" +
"<p>而<code>Cleaner</code>是过滤的执行者。不出所料，Cleaner内部定义了<code>CleaningVisitor</code>来进行标签的过滤。CleaningVisitor的过滤过程并不改变原始DOM树的值，而是将符合条件的属性，加入到<code>Element destination</code>里去。</p> \n" +
"<pre class=\"brush: java\">private final class CleaningVisitor implements NodeVisitor {\n" +
" private int numDiscarded = 0;\n" +
" private final Element root;\n" +
" private Element destination; // current element to append nodes to\n" +
"\n" +
" private CleaningVisitor(Element root, Element destination) {\n" +
" this.root = root;\n" +
" this.destination = destination;\n" +
" }\n" +
"\n" +
" public void head(Node source, int depth) {\n" +
" if (source instanceof Element) {\n" +
" Element sourceEl = (Element) source;\n" +
"\n" +
" if (whitelist.isSafeTag(sourceEl.tagName())) { // safe, clone and copy safe attrs\n" +
" ElementMeta meta = createSafeElement(sourceEl);\n" +
" Element destChild = meta.el;\n" +
" destination.appendChild(destChild);\n" +
"\n" +
" numDiscarded += meta.numAttribsDiscarded;\n" +
" destination = destChild;\n" +
" } else if (source != root) { // not a safe tag, so don't add. don't count root against discarded.\n" +
" numDiscarded++;\n" +
" }\n" +
" } else if (source instanceof TextNode) {\n" +
" TextNode sourceText = (TextNode) source;\n" +
" TextNode destText = new TextNode(sourceText.getWholeText(), source.baseUri());\n" +
" destination.appendChild(destText);\n" +
" } else { // else, we don't care about comments, xml proc instructions, etc\n" +
" numDiscarded++;\n" +
" }\n" +
" }\n" +
"\n" +
" public void tail(Node source, int depth) {\n" +
" if (source instanceof Element &amp;&amp; whitelist.isSafeTag(source.nodeName())) {\n" +
" destination = destination.parent(); // would have descended, so pop destination stack\n" +
" }\n" +
" }\n" +
"}</pre> \n" +
"<span id=\"OSC_h2_3\"></span>\n" +
"<h2>结束语</h2> \n" +
"<p>至此，Jsoup的全部模块都已经写完了。Jsoup源码并不多，只有14000多行，但是实现非常精巧，在读代码的过程中，除了相关知识，还验证几个很重要的思想：</p> \n" +
"<ul> \n" +
" <li><p>最好的代码抽象，是对现实概念的映射。</p> <p>这句话在看《代码大全》的时候印象很深刻。在Jsoup里，只要有相关知识，每个类的作用都能第一时间明白其作用。</p></li> \n" +
" <li><p>不要过度抽象</p> <p>在Jsoup里，只用到了两个接口，一个是<code>NodeVisitor</code>，一个是<code>Connection</code>，其他都是用抽象类或者直接用实现类代替。记得有次面试的时候被问到我们开发中每逢一个功能，都要先定义一个接口的做法是否必要？现在的答案是没有必要，过度的抽象反而会降低代码质量。</p> <p>另外，Jsoup的代码内聚性都很高，每个类的功能基本都定义在类的内部，这是一个典型的充血模型。同时有大量的facade使用，而避免了Factory、Configure等类的出现，个人感觉这点是非常好的。</p></li> \n" +
