在 Github Actions 中读取 JSON 文件 [英] Read JSON file in Github Actions

问题描述

我想读取 JSON 文件并使用 Github Actions YAML 文件中字符串中的属性.我该怎么做呢?(我想要package.json的版本)

I want to read a JSON file and use a property in a string in a Github Actions YAML file. How do I do this? (I want the version of the package.json)

推荐答案

使用内置的 fromJson(value)(请参阅此处:https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions#fromjson)

Use the built-in fromJson(value) (see here: https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions#fromjson)

读取文件取决于您使用的 shell.以下是 sh 的示例:

Reading a file depends on the shell you're using. Here's an example for sh:

name: Test linux job
on:
  push

jobs:
  testJob:
    name: Test
    runs-on: ubuntu-latest
    steps:
      - id: set_var
        run: |
          content=`cat ./path/to/package.json`
          # the following lines are only required for multi line json
          content="${content//'%'/'%25'}"
          content="${content//$'\n'/'%0A'}"
          content="${content//$'\r'/'%0D'}"
          # end of optional handling for multi line json
          echo "::set-output name=packageJson::$content"
      - run: |
          echo "${{fromJson(steps.set_var.outputs.packageJson).version}}"
