在 Azure 应用服务和 Visual Studio 中自动化应用程序离线

Question

我想使 App_Offline.htm 自定义且可更新，我正在使用 MSDeploy 以便从 Azure Pipeline 和 Visual Studio 2019 进行发布。Publish Works fins 在两者中。我的 Web 项目基于 .Net Core 2.2

我的问题是我想使用 MSDeploy 在发布之前使应用程序脱机并在发布之后删除 app_offline.htm。目前，我启用MSDeployAppOffline，它显示默认的“正在维护”秒数。直到App_offline.htm上传到应用服务中。然后我使用 Kudu 在线删除它。

后来我决定使用 MSDeploy CMDLine 远程添加和删除文件 app_offline.htm、beforePublish 和 AfterPublish ...这也有效，我必须在发布管道和 Visual Studio 中以纯文本形式保存我的密码方式“批处理脚本、PowerShell 脚本...”。

为了避免 Kudu 问题，我所要做的就是：

在我的 Azure 应用服务中添加应用程序设置

并将 < EnableMSDeployAppOffline >true 添加到我的发布配置文件中。

    <Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
      <PropertyGroup>
        <WebPublishMethod>MSDeploy</WebPublishMethod>
        <PublishProvider>AzureWebSite</PublishProvider>
        <LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration>
        <LastUsedPlatform>Any CPU</LastUsedPlatform>
        <SiteUrlToLaunchAfterPublish>mySiteUrl</SiteUrlToLaunchAfterPublish>
        <LaunchSiteAfterPublish>True</LaunchSiteAfterPublish>
        <ExcludeApp_Data>False</ExcludeApp_Data>
        <ProjectGuid>GUID</ProjectGuid>
        <MSDeployServiceURL>myapp.scm.azurewebsites.net:443</MSDeployServiceURL>
        <DeployIisAppPath>increditing-preview</DeployIisAppPath>
        <RemoteSitePhysicalPath />
        <SkipExtraFilesOnServer>True</SkipExtraFilesOnServer>
        <MSDeployPublishMethod>WMSVC</MSDeployPublishMethod>
        <EnableMSDeployBackup>True</EnableMSDeployBackup>
        <UserName>$myapp</UserName>
        <_SavePWD>True</_SavePWD>
        <_DestinationType>AzureWebSite</_DestinationType>
        /// EnableMSDeployAppOffline 
        <EnableMSDeployAppOffline>true</EnableMSDeployAppOffline>
        <MSDeployUseChecksum>true</MSDeployUseChecksum>

</Project>
