如何通过YAML将Azure WebJob部署至App Service正确路径？

问题描述 #

需将Worker Service控制台应用构建并部署为Azure App Service中的持续型WebJob，目标路径为site->jobs->continuous->$(webJobName)。当前YAML流水线构建、部署流程均执行成功，但WebJob被错误部署到site->wwwroot->$(webJobName)路径，不符合预期。手动上传工件至Azure App Service的WebJobs功能可正常运行，需修正自动化部署逻辑以部署到正确路径。

问题根源 #

1. 重复的publish任务干扰目录结构：第二个DotNetCoreCLI@2的publish操作直接将输出写入publish_output根目录，覆盖了第一个publish任务构建的App_Data/jobs/continuous/$(webJobName)标准WebJob目录结构，导致部署包内的层级不符合Azure WebJob的要求。
2. ArchiveFiles打包范围错误：当前打包根目录为$(Build.ArtifactStagingDirectory)，会将无关文件也纳入包中，破坏WebJob所需的目录层级。

修复步骤 #

• 移除重复的第二个DotNetCoreCLI@2 publish任务，保留第一个按WebJob标准目录结构输出的publish操作。
• 调整ArchiveFiles@2任务的rootFolderOrFile参数为$(Build.ArtifactStagingDirectory)/publish_output，确保仅打包符合WebJob目录要求的内容。
• 保持AzureWebApp@1任务参数不变，确认webJobType为Continuous、webJobName配置正确。
