使用 Office Pnp Sites Core 使用 App-Only 创建新式网站时出现 401

Question

所以，我在这里使用方法 2： https://www.vrdmn.com/2019/01/working-with-application-permissions.html

我的代码如下：

string siteUrl = "https://xx.sharepoint.com/sites/test212/";
            string siteUrl2 = "https://xx.sharepoint.com/sites/test2122/";

            //Client id and Client secret created through appregnew.aspx and permissions granted through appinv.aspx
            var authManager = new OfficeDevPnP.Core.AuthenticationManager();

            //PnP Core method
            ClientContext clientContext = authManager.GetAppOnlyAuthenticatedContext(siteUrl, "xx", "xx");

            var teamNoGroupSiteResult = await clientContext.CreateSiteAsync(new OfficeDevPnP.Core.Sites.TeamNoGroupSiteCollectionCreationInformation()
            {
                Url = siteUrl,
                Title = "Team no group Site Test",
                Description = "Site description",
                Lcid = 1033
            });

            var communicationSiteResult = await clientContext.CreateSiteAsync(new OfficeDevPnP.Core.Sites.CommunicationSiteCollectionCreationInformation()
            {
                Url = siteUrl2,
                Title = "Modern no group Site Test",
                Description = "Site description",
                Lcid 
 });

所以，我在我的租户中创建了应用程序仅注册，然后我尝试了这段代码，它说我未经授权。

我得到的错误是：

Answer 1

根据 this issue，目前尚无法使用 PnP。尽管在 Dev 分支中有代码更改来解决它，因此您可以复制它并创建您自己的 CreateSiteAsync 扩展方法并将 sitecollection.cs 复制到您自己的项目中。

无法根据相关 CreateAsync 方法中的代码自行调用 Rest API。

编辑：我永远无法让仅具有 ClientId 和机密的应用程序运行。试用概述的 ClientId 和 Cert 方法 here

Answer 2

你不能那样做即插即用。您可以尝试在 dev 分支中更改它的代码。这将允许您复制它并制作一个 CreateSiteAsync 扩展方法，然后只需将 sitecollction.cs 复制到您的项目。
