批量上载文档示例 SharePoint 外接程序
注意
示例将一个文件上载到文档库。 若要上载多个文件,需要扩展此示例。
Core.BulkDocumentUploader 示例外接程序使用控制台应用程序,通过使用 REST API 调用上载文件。 配置设置在 XML 和 CSV 文件中指定。
如果需要执行以下操作,请使用此解决方案:
- 将文件上载到 SharePoint Online。
- 迁移到 Office 365 并使用自定义迁移工具移动文件。
准备工作
若要开始,请从 GitHub 上的 Office 365 开发人员模式和做法项目下载 Core.BulkDocumentUploader 示例外接程序。
注意
本文中的代码按原样提供,不提供任何明示或暗示的担保,包括对特定用途适用性、适销性或不侵权的默示担保。
在运行代码示例之前,请执行以下操作:
使用下列信息编辑 OneDriveUploader.xml 文件:
- 您要在其中保存您的文本和 CSV 日志文件的位置。
- CSV 映射文件的文件路径(例如 C:\PnP\Samples\Core.BulkDocumentUploader\Input\SharePointSites.csv)。
- 要上载的公司策略文件的位置(例如 C:\PnP\Samples\Core.BulkDocumentUploader\Input\OneDriveFiles)。
- 您的 SharePoint Online 凭据。
- 要执行的文档操作(上载或删除)。
- 文件上载到文档库之后应用于文件的新文件名(例如 COMPANY POLICY DOCUMENT.xlsx)。
在 SharePointSites.csv 映射文件中,列出要将文件上载到的文档库 URL 以及要上载的公司策略文件的名称。
添加 OneDriveUploader.xml 文件的文件路径作为命令行参数。 要执行此操作,请在解决方案资源管理器中打开 Core.BulkDocumentUploader 项目属性,然后选择“属性”>“调试”。
使用 Core.BulkDocumentUploader 示例外接程序
从 Program.cs 的 Main 方法中,RecurseActions 方法在 OneDriveMapper.cs 中调用 Run 方法。 Run 方法从 SharePointSites.csv 获取要上载的文件的位置,然后调用 IterateCollection 方法。
public override void Run(BaseAction parentAction, DateTime CurrentTime, LogHelper logger)
{
CsvProcessor csvProcessor = new CsvProcessor();
logger.LogVerbose(string.Format("Attempting to read mapping CSV file '{0}'", this.UserMappingCSVFile));
using (StreamReader reader = new StreamReader(this.UserMappingCSVFile))
{
csvProcessor.Execute(reader, (entries, y) => { IterateCollection(entries, logger); }, logger);
}
}
SharePointSite.csv 文件列出要上载的文件以及要将该文件上载到的文档库。 然后 ,IterateCollection 方法执行以下操作,将文件上传到文档库:
获取要上载的文件。
确保用户有权限添加项目。
创建具有身份验证 Cookie 的 HttpWebRequest 对象、上载文档的 REST 字符串请求以及 HTTP 请求操作方法。
执行文件上载。
注意
使用 OneDriveUploader.xml 中指定的 FileUploadName 值覆盖文件名。
