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

我需要将提供商托管应用程序中的客户端Web部件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其添加到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. 您需要将应用程序部件从浏览器添加到任何页面
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”并单击“确定”。

3. 在应用程序部件中，单击Web部件标题旁边的下拉箭头，然后单击“导出”

4. 将.webpart文件复制到项目（EX：Template文件夹）

5. 添加此方法以创建发布页面并将应用程序部件添加到其中

    /// <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);
