在 Azure 应用服务和 Visual Studio 中自动化应用脱机

Question

我想让 App_Offline.htm 自定义和可更新我正在使用 MSDeploy 以便从 Azure Pipeline 和 Visual Studio 2019 发布。在两者中发布 Works 鳍。我的 Web 项目在 .Net Core 2.2 上

我的问题是我想使用 MSDeploy 使应用程序脱机，在发布前和删除 app_offline.htm 在发布后。目前，我启用MSDeployAppOffline，它显示默认的“维护中”秒。直到 App_offline.htm 上传到应用服务中。然后我用 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 中以纯文本格式保存我的密码，以各种方式“批处理脚本，PowerShell 脚本......”。

为了避免 Kudu 问题，我要做的就是：

在我的 Azure 应用服务中添加应用程序设置

并将 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>

并在 Azure Release Pipeline 中勾选 Take App Offline: Deploy Azure App Service Task
