转换为＆amp;(& converted to & sometimes on request.getParameter(“url”) in jsp servlet)

转换为＆amp;(& converted to & sometimes on request.getParameter(“url”) in jsp servlet)

我在JSP上输入非常简单的HTML：

<input type="text" name="url" value="" />

用户在上面的输入中输入以下值：

http://www.example.com/param1=a&param2=b

在servlet方面，当我执行request.getParameter("url")我得到以下内容：

http://www.example.com/param1=a&amp;param2=b

如何在没有&amp;情况下获取原始网址 来自request.getParameter ？

I have very simple input on HTML on JSP:

<input type="text" name="url" value="" />

User enters following value in above input:

http://www.example.com/param1=a&param2=b

On servlet side, when I do request.getParameter("url") I am getting following :

http://www.example.com/param1=a&amp;param2=b

How can I get original URL without &amp; from request.getParameter?

最满意答案

我终于找到了解决方案。 只需使用org.apache.commons.lang.StringEscapeUtils.unescapeHtml(url)来逃避任何“＆a mp;” （因为html编码而逃避任何字符）

I finally found the solution. Just use org.apache.commons.lang.StringEscapeUtils.unescapeHtml(url) to escape any "&a m p;" (for that matter to escape any characters due to html encoding)
