在 Windows 上分多个步骤运行后台进程

Question

在我下面的工作中，我尝试在一个步骤中本地启动一台服务器，并在下一步中连接到该服务器。这在 Linux 上工作得很好，但在 Windows 上，看起来所有后台进程都在执行下一步之前被终止。在名为 再次连接到服务器 (Windows) 的步骤上失败。

有什么解决办法吗？

解决方案似乎是在 Windows 上也使用 bash。服务器将在以下步骤中可用。

name: Test

on:
  push:
    branches:
      - '*'
  workflow_dispatch:

jobs:
  micro-server:
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ubuntu-latest, windows-latest]

    steps:
      - name: Create index.html
        run: echo "<h1>Hello world!</h1>" > index.html

      - name: Install dotnet-serve
        run: dotnet tool install --global dotnet-serve
 
      - name: Start server and connect to server 
        shell: bash
        run: |
            dotnet serve --port 5100 &
            BASE_URL=http://localhost:5100/
            
            timeout=30  # Timeout in seconds
            start_time=$(date +%s)  # Get current timestamp in seconds

            while true; do
                current_time=$(date +%s)
                elapsed_time=$((current_time - start_time))

                if (( elapsed_time >= timeout )); then
                    echo "Timeout reached. Server not available after $elapsed_time seconds."
                    exit 1  # Exit with non-zero status indicating failure
                fi

                # Check if server is reachable with curl
                if curl -f $BASE_URL &> /dev/null; then
                    echo "Server is now available at $BASE_URL after $elapsed_time seconds."
                    break
                else
                    echo "Waiting for server to become available at $BASE_URL... Elapsed time: $elapsed_time seconds"
                    sleep 1  # Wait for 1 second before checking again
                fi
            done

      - name: Connect to server again
        run: |
            curl http://localhost:5100
