以编程方式将客户端Web部件（应用程序部件）添加到sharepoint页面

Question

我需要将一个客户端Webpart从提供商托管的应用程序添加到其部署到的主机Web中的页面上。我尝试使用客户端对象模型的有限WebPart管理器来实现此目的，但这仅适用于属于.dwp或.webpart文件的xml数据。我使用了以下代码。有没有解决方法，从站点获取应用程序部分文件并将它们添加到Sharepoint页面？

        ClientContext clientconteext = new ClientContext("My Server URL");
        Microsoft.SharePoint.Client.File page = clientconteext.Web.GetFileByServerRelativeUrl("/sites/MySite/SitePages/Home.aspx");

        clientconteext.Load(clientconteext.Web);
        clientconteext.Load(page);
        clientconteext.ExecuteQuery();
        LimitedWebPartManager lwp= page.GetLimitedWebPartManager(PersonalizationScope.Shared);
        string webpartxml = "<?xml version=\"1.0\" encoding=\"utf-8\"?><Elements xmlns=\"http://schemas.microsoft.com/sharepoint/\"><WebPartPages:ClientWebPart runat=\"server\" FeatureId=\"5b1a14dd-8dbe-4963-8612-e7918e7fbc9a\" ProductWebId=\"5b1a14dd-8dbe-4963-8612-e7918e7fbc9a\" WebPartName=\"HomePageAppPart\" Title=\"Home App Part\" Description=\"WebPart Description\" WebPart=\"true\"></WebPartPages:ClientWebPart></Elements>";
        WebPartDefinition wpd = lwp.ImportWebPart(webpartxml);
        lwp.AddWebPart(wpd.WebPart, "Right", 1);
        clientconteext.ExecuteQuery();

Answer 1

这是您需要执行的步骤。

1. 您需要将自己的应用部分添加到浏览器的任何页面
2. 在“Web部件属性”窗格中，展开“高级”部分，将“导出模式”设置为“导出所有数据”，然后单击“确定”。



1. 在应用程序部分中，单击Web部件标题旁边的下拉箭头，然后单击“导出”



1. 将.webpart文件复制到项目（EX：模板文件夹）

2. 添加此方法以创建发布页面并将应用程序部分添加到其中

   /// <summary>
   /// Create a Publising Page
   /// </summary>
   /// <param name="clientContext">Client context</param>
   /// <param name="pageName">Page Name</param>
   /// <param name="pagelayoutname">Page Layout Name</param>
   public static File CreatePublishingPage(ClientContext clientContext, string pageName, string pagelayoutname)
   {
       var publishingPageName = pageName + ".aspx";
   
       Web web = clientContext.Web;
       clientContext.Load(web);
   
       List pages = web.GetListByUrl("/Pages/");
       clientContext.Load(pages.RootFolder, f => f.ServerRelativeUrl);
       clientContext.ExecuteQuery();
   
       Microsoft.SharePoint.Client.File file =
           web.GetFileByServerRelativeUrl(pages.RootFolder.ServerRelativeUrl + "/" + pageName + ".aspx");
       clientContext.Load(file, f => f.Exists);
       clientContext.ExecuteQuery();
       if (file.Exists)
       {
           file.DeleteObject();
           clientContext.ExecuteQuery();
       }
       PublishingWeb publishingWeb = PublishingWeb.GetPublishingWeb(clientContext, web);
       clientContext.Load(publishingWeb);
   
       if (publishingWeb != null)
       {
           List publishingLayouts = clientContext.Site.RootWeb.GetListByUrl("/_catalogs/masterpage/");
   
           ListItemCollection allItems = publishingLayouts.GetItems(CamlQuery.CreateAllItemsQuery());
           clientContext.Load(allItems, items => items.Include(item => item.DisplayName).Where(obj => obj.DisplayName == pagelayoutname));
           clientContext.ExecuteQuery();
   
           ListItem layout = allItems.Where(x => x.DisplayName == pagelayoutname).FirstOrDefault();
           clientContext.Load(layout);
   
           PublishingPageInformation publishingpageInfo = new PublishingPageInformation()
           {
               Name = publishingPageName,
               PageLayoutListItem = layout,
           };
   
           PublishingPage publishingPage = publishingWeb.AddPublishingPage(publishingpageInfo);
           publishingPage.ListItem.File.CheckIn(string.Empty, CheckinType.MajorCheckIn);
           publishingPage.ListItem.File.Publish(string.Empty);
           clientContext.Load(publishingPage);
           clientContext.ExecuteQuery();
           return publishingPage.ListItem.File;
       }
       return null;
   }
   
   /// <summary>
   /// Adds the Web Part to the page
   /// </summary>
   /// <param name="clientContext">Client Context</param>
   /// <param name="newWeb">New Web</param>
   public static void AddWebpartToWebPartPage(ClientContext clientContext, File file)
   {
       file.CheckOut();
   
       //Get webparts xml
       string webpart = System.IO.File.ReadAllText(System.Web.Hosting.HostingEnvironment.MapPath(string.Format("~/{0}", "Template/RegistroDeSolicitudes.webpart")));
   
       // Requires Full Control permissions on the Web
       LimitedWebPartManager wpmgr = file.GetLimitedWebPartManager(PersonalizationScope.Shared);
       WebPartDefinition wpd = wpmgr.ImportWebPart(webpart);
       wpmgr.AddWebPart(wpd.WebPart, "Header", 0);
       file.CheckIn(String.Empty, CheckinType.MajorCheckIn);
       file.Publish(string.Empty);
       clientContext.ExecuteQuery();
   }
   

并调用方法：

Microsoft.SharePoint.Client.File publishingPage = Helpers.CreatePublishingPage(cc, "Solicitudes", "BlankWebPartPage");
Helpers.AddRegistroDeSolicitudesWebpartToWebPartPage(cc, publishingPage);
