docsify是一个很神奇的文档生成工具，利用markdown文档动态生成文档网站。与 GitBook 不同，它不会生成静态的 HTML 文件。相反，它会智能地加载并解析Markdown 文件，并将它们展示为一个网站。这里简要介绍一下一个实例，在官方配置的基础上增加一个手动切换主题的功能，官方文档（https://docsify.js.org/#/zh-cn/)。

})因为配置了密码登陆，所以需要后端nginx配置一下：
yum install httpd-tools htpasswd -c /etc/nginx/.htpasswd your_username
注意目录/etc/nginx要存在，your_username是账户，执行上述命令后，系统会提示你输入密码，并将其加密存储到 .htpasswd 文件中。
然后是具体的nginx配置，http段：
http{
# 其他配置
map $status $auth_realm {
~^4 "Restricted_$request_time"; # 动态生成 realm
}
}server段：
add_header Vary "Cookie,Authorization"; # 确保不同凭证得到不同缓存副本
add_header X-Content-Type-Options "nosniff"; # 阻止 MIME 类型嗅探
auth_basic $auth_realm; # 使用动态 realm
location / {
auth_basic "Restricted Access"; # 提示信息
auth_basic_user_file /etc/nginx/.htpasswd; # 密码文件路径
try_files $uri $uri/ /index.html;
}
location = /logout {
# 生成动态 realm 使浏览器认为这是新认证域
add_header WWW-Authenticate 'Basic realm="Restricted_$request_time"';
# 阻止浏览器缓存认证状态
add_header Cache-Control "no-cache, no-store, must-revalidate";
add_header Pragma "no-cache";
add_header Expires "0";
# 清除浏览器数据（部分浏览器生效）
add_header Clear-Site-Data '"cache", "storage"';
# 返回 401 触发浏览器认证弹窗
return 401;
