if ($request_uri ~ ^(.*/)index.html$) {
    return 301 $1;
}
# non-www to www

# http to https
if ( $scheme = http ){
    return 301 https://$server_name$request_uri;
}

使用了cloudflare的https重定向设置

如果使用了cloudflare，http 到https的转向需要到cloudflare上面设置

How do I redirect all visitors to HTTPS/SSL?

20180307更新

添加两个page rules 301规则也行，之前的always https没这个选项了
