在 github 操作脚本中迭代 github.event.commits

Question

我已经在 Github actions 中编写了action。在推送事件中，GitHub 提供了一个以 github 开头的变量。

变量的 Json 预览是：

{
    "event_name": "push",
    "event": {
      "after": "aaaaaaaaaaaaaaaaa",
      "base_ref": null,
      "before": "bbbbbbbbbbbbbbbb",
      "commits": [
        {
          "author": {
            "username": "myUser"
          },
          "id": "bbbbbbbbbbbbbbbb",
          "message": "myCommitMessage",
          "url": "https://github.com/myUser/myRepo/commit/bbbbbbbbbbbbbbbb"
        }
      ],
      "compare": "https://github.com/myUser/myRepo/compare/" 
      }
  }

我想编写一个在 github.event.commits 上迭代的脚本并创建如下内容：

commits=${{github.event.commits}}
length=${#commits[@]}
for (( i = 0; i < length; i++ )); do
  commit=${{github.event.commits[i]}}
  echo url=${{commit.url}}
  echo sha=${{commit.id}}
  echo actor=${{commit.author.username}}
  echo message=${{commit.message}}
done

但是 id 不起作用。我收到这个错误：

Unrecognized named-value: 'i'. Located at position 22 within expression: github.event.commits[i]

一定要bash吗？您可以使用 jq，但是如果它变得更复杂，这可能会变得有点难看：

- run: echo '${{ toJSON(github.event.commits) }}' | jq ".[0].author"

否则我可以推荐 github-script 操作 这应该会让你的代码变得更好：

- uses: actions/github-script@v6
  with:
    script: |
      const commits = ${{ toJSON(github.event.commits) }}
      for (const commit of commits) {
        console.log(commit);
      }
