【已解决】Hexo NexT使用Gitalk未找到相关的Issues进行评论Error:Validation Failed

本文主要解决了以下问题

  • 使用Github账户登陆评论区时会返回首页或者404报错
  • 使用Github账户登陆评论区时401报错
  • 未找到相关的Issues进行评论，请联系XXX进行创建
  • Error Not Found错误
  • Error: Validation Failed错误

什么是Gitalk

Gitalk：一个基于 Github Issue 和 Preact 开发的评论插件

安装教程

我是参考asdfv1929撰写的如何在Hexo NexT主题中集成Gitalk评论系统搭建的，有需要的同学可以移步看一下。

本文主要解决了以下问题

  • 使用Github账户登陆评论区时会返回首页或者404报错
  • 使用Github账户登陆评论区时401报错
  • 未找到相关的Issues进行评论，请联系XXX进行创建
  • Error Not Found错误
  • Error: Validation Failed错误

配置前最好确认你使用的主题当前是否集成了Gitalk，如果支持，请按主题教程配置。否则可能会出现以外的冲突和错误。

使用Github账户登陆评论区时会返回首页或者404报错

  1. 如果设置的有域名解析，请到GitHub Setting中检查Application设置中的回调地址，也就是Authorization callback URL选项，将其设置为域名解析的地址(地址要用http://或 https://开头)

  2. 如果你的评论仓库或者GitHub Page仓库是private的也是会出现404错误的。改成public即可解决。

使用Github账户登陆评论区时401报错

这个问题是由于Application设置中的Homepage地址填写错误引起的，请到GitHub Setting->Application中检查Homepage的地址填写是否正确。确保地址是https协议。（据@blacklisten反馈）

未找到相关的Issues进行评论，请联系XXX进行创建

这个问题则需要检查安装过程中某些步骤是否出错了，重点检查主题的_config.yml的gitalk配置是否出错

# gitalk Comments
gitalk:
  enable: true #是否开启
  githubID: JunzhouLiu #你的Github用户名
  repo: JunzhouLiu.github.io #Github仓库名称
  ClientID: c2xxxxxxxxxd5 #创建的Application ClientID
  ClientSecret: 2dxxxxxxxf42 #创建的Application ClientSecret
  adminUser: JunzhouLiu # 评论初始化账户(GitHub ID)
  distractionFreeMode: true # 是否开启分心自由模式 也就是免打扰

如果你的Hexo所在的仓库未开启Issues选项也是会报这个错误的。据@PeTu反馈

Error Not Found

由于部分主题集成了Gitalk功能，或者你使用的主题后续支持了Gitalk，并且你升级了主题，此时则可能会出现Error Not Found错误，原因是在主题_config.yml文件中Gitalk配置选项的字段发生了改变，此时请检查你的Gitalk配置字段是否和本文配置的字段一致，如果不一致，请按照你主题的配置填写信息。
例如NexT主题的集成的Gitalk字段配置是:

# Gitalk
gitalk:
  enable: false
  github_id:  # Github repo owner
  repo:  # Repository name to store issues.
  client_id:  # Github Application Client ID
  client_secret:  # Github Application Client Secret
  admin_user:  # GitHub repo owner and collaborators, only these guys can initialize github issues
  distraction_free_mode: true # Facebook-like distraction free mode

很明显githubID变成了github_id,ClientID变成了client_id,此时就会出现该错误。

Error: Validation Failed

这个问题就比较复杂了，部分文章的评论区会报Error: Validation Failed,具体原因是由于 Github 限制 labal 长度不能超过 50引起的，该问题解决方案来自Gitalk项目仓 Issues115，通过MD5加密ID来缩短labal长度。
具体操作如下

  1. 创建md5.min.js文件

创建或者从GitHub下载md5.min.js文件，放置到themes\next\source\js\src\目录。点此下载
