我有一个 jsp 页面，它在 get 参数中接受一个字符串mystring：
http://localhost:8080/MyApp/index.jsp?mystring=
我正在尝试将此字符串放在<pre>标签内。
<body>
<pre>
<%= request.getParameter("mystring") %>
</pre>
</body>
当我打电话时，http://localhost:8080/MyApp/index.jsp?mystring=<html>什么都没有打印。然后我尝试了 URLUTF8Encoder并且它适用于大多数标签但是当我通过这样的东西时：
<script>window.serq=[];StackExchange={ready:function(f){serq.push(f)}}</script>
