【问题描述】：
我有一个jsp页面，它在get参数mystring中接受一个字符串：
http://localhost:8080/MyApp/index.jsp?mystring=
我正在尝试将此字符串放在 <pre> 标记内。
<body>
<pre>
<%= request.getParameter("mystring") %>
</pre>
</body>
当我调用http://localhost:8080/MyApp/index.jsp?mystring=<html> 时，没有打印任何内容。
然后我尝试了URLUTF8Encoder，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>

});
</script>
我没有得到任何回应。
url编码后是这样的：

我在这里做错了什么？有什么方法可以不编码就显示html？
- 我只需要发送一个 GET 请求。不是 POST 请求。
- 没有javascript。
【问题讨论】：
-
你意识到你已经在使用javascript了，对吧？
-
我的 jsp 中没有脚本。我只需要像文本一样在 pre 标签中显示它。
-
所以你想像文本一样显示html，对吧？
-
@Raman 。是的..但只在前标签内..
-
也许你可以看看这个答案：stackoverflow.com/questions/4526502/…Cheers！
