如何自动获取文件夹中所有文件的共享点链接（Link for 'People with existing access'）？

Question

我的 Sharepoint 文件夹中有大量文件，我需要与组织外部有权访问该文件夹的人员共享 link 一些单独的文件。我可以通过手动选择每个文件来获取 link，将 link 选项更改为 'People with existing access' 并单击应用。这会给我一个看起来像这样的 link： <https://.sharepoint.com/:p:/r/sites/Marketing/Shared%20Documents/Branding%20Elements.pptx?d=w1bae13735fdb4b1d9dd0ae217bc2d911&csf=1&e=aojURR>

但是，对数百个文件执行此操作是不切实际的。有人可以帮忙 easier/quicker solution/automation 吗？

非常感谢！

您可以使用 SharePoint 客户端对象模型 (CSOM) 使用您的用户凭据获取共享 links（如果网站启用了 MFA，您将需要使用应用程序凭据，如所述here):

using Microsoft.SharePoint.Client;
using OfficeDevPnP.Core;
using System;
using System.Security;
static void Main()
{
    string siteUrl = "https://contoso.sharepoint.com/sites/demo";

    SecureString password = new SecureString();
    foreach (char c in "password".ToCharArray()) password.AppendChar(c);

    using (var cc = new AuthenticationManager().GetSharePointOnlineAuthenticatedContextTenant(siteUrl, "username", password))
    {
        string folderUrl = @"https://contoso.sharepoint.com/sites/demo/Shared Documents/TestFolder";
        Uri folderUri = new Uri(folderUrl);

        Folder folder = cc.Web.GetFolderByServerRelativeUrl(folderUri.AbsolutePath);
        cc.ExecuteQuery();

        cc.Load(folder.Files);
        cc.ExecuteQuery();
        FileCollection fileCol = folder.Files;
        foreach (File file in fileCol)
        {
            Console.WriteLine(file.LinkingUrl);
        }
    }
}

上面的代码应该给你“具有现有访问权限的人”link。下面的代码显示了如何创建其他类型的 links:

using Microsoft.SharePoint.Client;
using OfficeDevPnP.Core;
using System;
using System.Security;
static void Main()
{
    string siteUrl = "https://contoso.sharepoint.com/sites/demo";
    SecureString password = new SecureString();
    foreach (char c in "password".ToCharArray()) password.AppendChar(c);

    //Use the commented out line for App Only Authentication
    //using (var cc = new AuthenticationManager().GetAppOnlyAuthenticatedContext(siteUrl, "ClientID", "ClientSecret"))
    using (var cc = new AuthenticationManager().GetSharePointOnlineAuthenticatedContextTenant(siteUrl, "username", password))
    {
        string fileUrl = @"https://contoso.sharepoint.com/sites/demo/Shared Documents/TestFolder/File.xlsx";
        Uri fileUri = new Uri(fileUrl);

        Microsoft.SharePoint.Client.File file = cc.Web.GetFileByServerRelativeUrl(fileUri.AbsolutePath);
        cc.Load(file);

        //Existing Access Link (i.e. "People with existing access")
        //file.LinkingUrl

        //Organization Link (i.e. "People in org with link")
        bool isEdit = true;
        var orgEditLink = Microsoft.SharePoint.Client.Web.CreateOrganizationSharingLink(cc, fileUrl, isEdit);

        //Anonymous Link (i.e. "Anyone with the link")
        ClientResult<String> anonEditLink = Microsoft.SharePoint.Client.Web.CreateAnonymousLink(cc, fileUrl, isEdit);
        string anonEditLink2 = cc.Web.CreateAnonymousLinkForDocument(fileUrl, ExternalSharingDocumentOption.Edit);

        //Anonymous Link with Expiration (not available in GUI)
        DateTime five_days = DateTime.Now.AddDays(5);
        ClientResult<String> anonExpEditLink = Microsoft.SharePoint.Client.Web.CreateAnonymousLinkWithExpiration(cc, fileUrl, isEdit, five_days.ToString("yyyy-MM-ddThh:mm:ssZ"));
        string anonExpEditLink2 = cc.Web.CreateAnonymousLinkWithExpirationForDocument(fileUrl, ExternalSharingDocumentOption.Edit, five_days);

        //User Share Link (i.e. "People you specify can edit")
        String target_email = "email@example.com";
        bool send_email = false;
        SharingResult userEditLink = cc.Web.ShareDocument(fileUrl, target_email, ExternalSharingDocumentOption.Edit, send_email);

        cc.ExecuteQuery();

        Console.WriteLine(file.LinkingUrl);
        Console.WriteLine(orgEditLink.Value);
        Console.WriteLine(anonEditLink.Value);
        Console.WriteLine(anonEditLink2);
        Console.WriteLine(anonExpEditLink.Value);
        Console.WriteLine(anonExpEditLink2);
        foreach (SPInvitationCreationResult invuser in userEditLink.InvitedUsers)
        {
            Console.WriteLine(invuser.InvitationLink);
        }

    }

}
