GitHub Action部署Azure WebApp后wwwroot目录为空问题求助

我尝试通过GitHub Action将Web应用部署到Azure，但部署完成后site/wwwroot目录完全为空，相关情况如下：

• 流水线执行无任何失败
• 发布的产物包含正确的文件
• 手动通过FTP将文件上传至wwwroot可正常运行

排查与解决思路 #

• 修正路径分隔符：当前AZURE_WEBAPP_PACKAGE_PATH使用Windows反斜杠\，建议改为正斜杠/（Name/publish），避免跨步骤的路径解析异常。
• 验证artifact内容：在deploy步骤中添加run: dir "${{ env.AZURE_WEBAPP_PACKAGE_PATH }}"命令，确认下载后的目录存在文件，排除上传/下载过程中的文件丢失问题。
• 调整部署包路径：尝试将azure/webapps-deploy的package参数改为${{ env.AZURE_WEBAPP_PACKAGE_PATH }}/**，确保工具能识别到目录下所有待部署文件。
• 检查App Service运行模式：确认Azure门户中App Service的“常规设置”是否开启“从包运行”，开启后文件不会解压到wwwroot，而是直接从包运行，此时wwwroot为空属于正常情况，但应用应能正常启动。
• 查看详细部署日志：访问日志中的log_url，查看OneDeploy的具体执行记录，排查是否存在静默失败或文件上传遗漏的情况。
