如何：自定义已中断的方案的部署
上次修改时间： 2010年9月22日
适用范围： SharePoint Server 2010
当源场和目标场之间的明文连接总是可用时，内容部署将正常运行。但是，源创作场和目标生产场之间的可靠的功能连接并不总是可用。例如，当存在地理障碍、阻止访问的防火墙或网络中断时，使用网络连接将导出包传输到目标生产场是不可靠的。在这些情况下，Microsoft 建议您使用 Microsoft SharePoint Server 2010 对象模型和 SharePoint Foundation 内容迁移 API 以编程方式完成内容迁移的导出和导入步骤，并找出用于将导出包传输到目标生产场的替代方式，然后运行自定义导入代码。
如部署服务器之间的内容中所述，每个内容部署都包含三个步骤：导出、传输和导入。在此方案中，通过手动而不是以编程方式处理传输。例如，可能通过便携媒体传输导出的内容包或使用 FTP 客户端将数据上载到可从其中导入的单独的文件共享。
使用内容迁移 API 导出内容包
调用带有要指定的选项的内容迁移 API。
存储更改标记。
应用程序将运行导出、检查异常并根据需要报告异常。如果运行成功，则应用程序将创建带有提供的名称的导出包并将其存储到提供的位置。
备注
在导出完成并创建内容包之后，可以使用 FTP、便携媒体等来传输已导出的包。在将数据传输到导入过程可以访问的文件位置之后，可以开始导入。
使用内容迁移 API 导入内容包
在导出过程中使用对象模型查找创建的文件。如果正在使用提供的代码示例，则文件名为 export.cmp。
运行导入代码。导入代码将执行以下操作：
使用代码中定义的属性集来创建 SPImportSettings 对象。
创建新的 SPImport 对象并管理预先导入和导入后更改标记、内容版本控制、缓存设置和针对新部署的内容的安排。
备注
由于性能方面的原因，默认情况下，SharePoint Server 2010 不调用事件接收器。默认情况下，当内容部署创建内容时不会触发侦听器。但是，如果使用的是第三方应用程序或要求在导入过程中触发事件接收器的自定义代码，则可将 SuppressAfterEvents 属性设置为 false。在设置此标志之后，可能会遭受重大的性能损失，但是会接收到导入中指定的所有要求。
备注
在源服务器上调用内容迁移 API 并将特定选项（例如，RetainObjectIdentity 属性）设置为 true。
示例
为了帮助您将 SharePoint Foundation 内容迁移 API 与 SharePoint Server 2010 内容部署功能一起使用，本主题包含一个将内容迁移 API 与 SharePoint Server 2010 内容部署一起使用的代码示例。此示例演示如何将内容部署功能与内容迁移 API 进行交互以创建导出；在使用内容迁移 API 完成导出、导入和路径时所需的概念和语法；以及 SharePoint Server 2010 内容部署的作业定义和执行步骤。
示例代码划分为两个较小的应用程序：导出应用程序和导入应用程序。
