网站部署https后,浏览器提示不安全, 不出现绿色小锁图标?
访问网站后,按f12,浏览器提示:
Mixed Content: The page at \’https://www.xxx.com/\’\’ was loaded over HTTPS, but requested an insecure image \’http://www.xxx.com/uploads/2018/12/3.png\’. This content
原因是在https页面中，如果调用了http资源，那么浏览器就会抛出一些错误,
解决办法:在header中加入Upgrade-Insecure-Requests,会告诉浏览器可以把所属本站的所有http连接升级为https连接,外站请求保持默认;
添加header方法:
1.iis7
或直接在网站根目录web.config中定义
<?xmlversion=\”1.0\”encoding=\”UTF-8\”?><configuration><system.webServer><httpProtocol><customHeaders><addname=\”Content-Security-Policy\”value=\”upgrade-insecure-requests\”/></customHeaders></httpProtocol></system.webServer></configuration>
2.apache
可直接在网站根目录.htaccess中定义
<IFModulemod_headers.c>HeaderaddContent-Security-Policyupgrade-insecure-requests</IFModule>
3. nginx
server{listen80;server_name(myservername);add_headerContent-Security-Policy\”upgrade-insecure-requests\”;location/{proxy_passhttp://localhost:5000;}}
