Github Actions：检查步骤状态

Question

我在 CI 的工作中有一些可能会引发错误的步骤。我不希望在出现错误的每一步都重新启动工作流程，并希望转到检查这些步骤的最后一步并以失败的方式完成此工作。但我无法在之前的步骤中获取状态信息。

name: CI
on: [pull_request]
jobs:
  myjob:
    runs-on: ubuntu-latest
    steps:
      - name: Step 1
        id: hello
        run: <any> 
        continue-on-error: true
      - name: Step 2
        id: world
        run: <any> 
        continue-on-error: true
      - name: Check on failures
        if: job.steps.hello.status == failure() || job.steps.world.status == failure()
        run: exit 1

当我在“if”或“run”中使用下一个构造时，将得到：steps -> {}, job.steps -> null。

如何获取状态信息？

更新：steps上下文现在包含有关默认情况下每个步骤执行的详细信息。使用outcome每个步骤的属性，我们可以检查其执行的结果。

name: CI
on: [pull_request]
jobs:
  myjob:
    runs-on: ubuntu-latest
    steps:
      - name: Step 1
        id: hello
        run: <any> 
        continue-on-error: true
      - name: Step 2
        id: world
        run: <any> 
        continue-on-error: true
      - name: Check on failures
        if: steps.hello.outcome != 'success' || steps.world.outcome != 'success'
        run: exit 1

原始答案 查看步骤上下文的文档，它似乎不包含有关步骤以外的任何信息outputs。这些必须由步骤明确定义。这就是步骤上下文为空的原因{}。

不幸的是，据我所知，可以访问的步骤没有默认状态。该解决方案涉及从每个步骤手动定义状态输出变量。

name: CI
on: [pull_request]
jobs:
  myjob:
    runs-on: ubuntu-latest
    steps:
      - name: Step 1
        id: hello
        run: echo ::set-output name=status::failure
        continue-on-error: true
      - name: Step 2
        id: world
        run: echo ::set-output name=status::success
        continue-on-error: true
      - name: Dump steps context
        env:
          STEPS_CONTEXT: ${{ toJson(steps) }}
        run: echo "$STEPS_CONTEXT"
      - name: Check on failures
        if: steps.hello.outputs.status == 'failure' || steps.world.outputs.status == 'failure'
        run: exit 1

这将创建以下上下文输出并且作业失败。

{
  "hello": {
    "outputs": {
      "status": "failure"
    }
  },
  "world": {
     "outputs": {
      "status": "success"
    }
  }
}

您可以使用setps.STEPNAME.outcome 属性获取状态，该属性与 success() 或 failure() 检查相关联

name: CI
on: [pull_request]
jobs:
  myjob:
    runs-on: ubuntu-latest
    steps:
      - name: Step 1
        id: hello
        run: <any> 
        continue-on-error: true
      - name: Step 2
        id: world
        run: <any> 
        continue-on-error: true
      - name: Check on failures
        if: (${{ success() }} || ${{ failure() }}) && (${{ steps.hello.outcome }} == 'failure' || ${{ steps.world.outcome }} == 'failure')
        run: exit 1
