java - 如何将 YouTube 链接设为嵌入？

Question

<%
String song = request.getParameter("songname");
String band = request.getParameter("band");
String url = request.getParameter("url");
%>
<div align="center">
    <br><br>  <% out.print(band + " - " + song); %><br><br>
    <iframe width="560" height="315" src="<%out.print(url);%>" frameborder="0" allowfullscreen></iframe>
</div>
<%
%>

假设我得到的网址是这样的 https://www.youtube.com/watch?v=kXYiU_JCYtU我想让它看起来像 https://www.youtube.com/embed/kXYiU_JCYtU这样我就可以把它放在 src=""
