本文執行個體講述了jsp實現防盜鏈的方法。分享給大家供大家參考，具體如下：
最近碰到盜鏈的問題，即複製一個url地址，在另一個地方也能訪問。
index.jsp頁面
<html> <head><title>Simple jsp page</title></head> <body>Place your content here here is index jsp get header info <a href="a.jsp">a.jsp</a> </body></html>
a.jsp頁面
<html> <head><title>Simple jsp page</title></head> <body>Place your content here here is a. jsp get header info <%=request.getHeader("Referer")%> <%if(null == request.getHeader("Referer") || request.getHeader("Referer").indexOf("yourdomain.com") < 0){%> 做人要厚道 <%}else{%> 合法訪問 <%}%> </body></html>
即從內部訪問可以，直接粘貼地址在另一個瀏覽器裡訪問禁止
希望本文所述對大家JSP程式設計有所協助。
