Mixed Content: The page at 'https://app1515.acapp.acwing.com.cn/' was loaded over HTTPS, 
but requested an insecure XMLHttpRequest endpoint 'http://120.78.237.34:8000/getinfo/?platform=WEB'. 
This request has been blocked; the content must be served over HTTPS.

GET https://120.78.237.34:8000/static/image/acwing-logo.png net::ERR_CONNECTION_RESET

=======================
起因：HTTPS页面里动态的引入HTTP资源，比如引入一个js文件，被直接block掉.在HTTPS页面里通过AJAX的方式请求HTTP资源，也被直接block掉。
修改：原本页面的资源链接部分以及ajax里我都是写的ip（http://120.78.237.34:8000），现在那部分改成https://app1515.acapp.acwing.com.cn/就没问题了。

重新启动nginx之后打开acapp，只刷出背景图。报错情况如下：
access to xmlhttprequest at ... from origin ... has been blocked by cors policy ...
Error 111 connecting to 127.0.0.1:6379. Connection refused.

=======================
重新启动redis：sudo redis-server /etc/redis/redis.conf 再uwsgi --ini scripts/uwsgi.ini
