注册Leancloud账号：https://www.leancloud.cn

注册完以后需要创建一个应用，名字可以随便起，然后 进入应用->设置->应用key

拿到你的appid和appkey之后，打开主题配置文件（我是…\themes\next_config.yml）搜索 valine，填入appid 和 appkey

valine:
  enable: true # When enable is set to be true, leancloud_visitors is recommended to be closed for the re-initialization problem within different leancloud adk version
  appid: XO7jV马赛克zGzoHsz # Your leancloud application appid
  appkey: Amg1Fl马赛克2NfhcO # Your leancloud application appkey
  notify: false # Mail notifier. See: https://github.com/xCss/Valine/wiki
  verify: false # Verification code
  placeholder: Just go go # Comment box placeholder
  avatar: mm # Gravatar style
  guest_info: nick,mail,link # Custom comment header
  pageSize: 10 # Pagination size
  language: # Language, available values: en, zh-cn
  visitor: false # leancloud-counter-security is not supported for now. When visitor is set to be true, appid and appkey are recommended to be the same as leancloud_visitors' for counter compatibility. Article reading statistic https://valine.js.org/visitor.html
  comment_count: true # If false, comment count will only be displayed in post page, not in home page
  #post_meta_order: 0

最后在Leancloud -> 设置 -> 安全中心 -> Web 安全域名把你的域名加进去
