部署https后浏览器提示不安全,不出现绿色小锁?

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 ' 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

<?xml version="1.0" encoding="UTF-8"?>

<configuration>

<system.webServer>

<httpProtocol>

<customHeaders>

<add name="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

<IFModule mod_headers.c>

Header add Content-Security-Policyupgrade-insecure-requests

</IFModule>

3. nginx

server {

listen 80;

server_name (myservername);

add_header Content-Security-Policy "upgrade-insecure-requests";

location / {

proxy_pass http://localhost:5000;

}

}

通过这些设置后绿色小锁就重新出现了。
