1、問題出現場景javascript
項目從http升級到https後,jsp頁面存在發送http請求的狀況下就會出現該異常。由於HTTPS 是 HTTP over Secure Socket Layer,以安全爲目標的 HTTP 通道,因此在 HTTPS 承載的頁面上不容許出現 http 請求。html
2、解決辦法java
在jsp頁面中,添加下面的meta頭就能夠了安全
<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests" />jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests"> </head> <body> <script type="text/javascript"> </script> </body> </html>
