GithubAction学习

触发Action构建

curl -X POST https://api.github.com/repos/$用户/$仓库名/dispatches -H "Accept: application/vnd.github.everest-preview+json" -H "Authorization: token $YOUR_API_TOKEN" --data '{"event_type": "StartAction"}'

GITHUB设置Secrets

构建示例

构建触发

#定时任务触发构建
on:
  schedule:
    - cron: "0 0 * * *"

#通过接口触发构建
on:
  repository_dispatch:
    types:
      - StartAction

#通过 push 代码触发构建
on:
  push:
    branches:
      - master

# 当 push 到 master 分支，或者创建以 v 开头的 tag 时触发
on:
  push:
    branches:
      - master
    tags:
      - v*

Dependabot实现更新项目中的依赖项

当你在项目中使用很多第三方库（例如JavaScript项目中的npm包）时，这些库会不断更新，有时是为了添加新功能，有时是为了修复安全漏洞。手动跟踪和更新这些库可能既费时又容易出错。这就是Dependabot发挥作用的地方。
