基本功能 - Gihub Actions

使用变量

jobs:
  example-job:
      steps:
        - name: Connect to PostgreSQL
          run: node client.js
          env:
            POSTGRES_HOST: postgres
            POSTGRES_PORT: 5432

添加脚本到工作流程

jobs:
  example-job:
    steps:
      - name: Run build script
        run: ./.github/scripts/build.sh
        shell: bash

在作业之间共享数据

jobs:
  example-job:
    name: Save output
    steps:
      - shell: bash
        run: |
          expr 1 + 1 > output.log
      - name: Upload output file  # 上传
        uses: actions/upload-artifact@v3
        with:
          name: output-log-file
          path: output.log
      - name: Download a single artifact  # 下载
        uses: actions/download-artifact@v3
        with:
          name: output-log-file

表达式

steps:
  - uses: actions/hello-world-javascript-action@e76147da8e5c81eaf017dede5645551d4b94427b
      if: ${{ <expression> }}

运算符(JS 通用)

函数

• contains( search, item )

• startsWith( searchString, searchValue )

• endsWith( searchString, searchValue )

• format( string, replaceValue0, replaceValue1, …, replaceValueN)

• join( array, optionalSeparator )

• toJSON(value)

• fromJSON(value)

• hashFiles(path)

• success() 如果前面的步骤都没有失败或被取消，则返回 true。

• always()

• cancelled()

• failure()

• * 对象过滤器

[
  { "name": "apple", "quantity": 1 },
  { "name": "orange", "quantity": 2 },
  { "name": "pear", "quantity": 1 }
]

筛选器 fruits.*.name 返回数组 [ “apple”, “orange”, “pear” ]。
