GitHub Actions 如果包含不适用于 env.VARIABLE 的函数答案

【问题描述】：

我已经设置了一个环境变量：

echo "::set-env name=PROJECT_TO_TEST::$(sh scripts/test.sh)"

test.sh 只是回显“SomeString, MoreString”

我确实看到 PROJECT_TO_TEST 变量通过以下操作正确设置：

echo "env.PROJECT_TO_TEST = ${{ env.PROJECT_TO_TEST }}"

输出“env.PROJECT_TO_TEST = SomeString, MoreString”

在接下来的一步中，我正在执行 if 检查以查看 PROJECT_TO_TEST 变量是否包含一些字符串，如下所示：

- name: Conditionally Run
  if: contains('${{ env.PROJECT_TO_TEST }}', 'SomeString')
  run: |
    echo "SomeString did exist and should run"
- name: Conditionally Run
  if: contains('${{ env.PROJECT_TO_TEST }}', 'ShouldNotRun')
  run: |
    echo "ShouldNotRun"

在这种情况下，应该只打印“SomeString did exist and should run”，但也打印“ShouldNotRun”。

if 中不需要${{}}，因为它可以直接访问env 上下文。

  - run:  echo PROJECT_TO_TEST=SomeString,MoreString >> $GITHUB_ENV
  - name: Conditionally Run
    if:   contains(env.PROJECT_TO_TEST, 'SomeString')
    run:  echo "SomeString did exist and should run"
  - name: Conditionally Run
    if:   contains(env.PROJECT_TO_TEST, 'ShouldNotRun')
    run:  echo "ShouldNotRun"

【解决方案2】：

Github 已弃用“set-env”。

set-env 命令已禁用。请升级到使用环境文件或通过将ACTIONS_ALLOW_UNSECURE_COMMANDS 环境变量设置为true 来选择不安全的命令执行。更多信息请见：https://github.blog/changelog/2020-10-01-github-actions-deprecating-set-env-and-add-path-commands/

您应该改用以下语法：

   - name: set env variable
     run: |
       echo "PROJECT_TO_TEST=$(sh scripts/test.sh)" >> $GITHUB_ENV
  
   # Then you can use it in your if statement like so 
   - name: Conditionally Run
     if: contains(env.PROJECT_TO_TEST, 'SomeString')
     run: |
       echo "let's run"
