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 
 });

因此，我在租户中创建了仅应用程序注册，然后尝试了此代码，并说我未经授权。

我得到的错误是：

Answer 1

根据this issue，到目前为止无法使用PnP。尽管在Dev分支中有代码更改来解决它，所以您可以复制它并创建自己的CreateSiteAsync扩展方法，然后将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。

的ClientId和Cert方法

Answer 2

您不能执行该PnP。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创建CreateSiteAsync扩展方法，然后将sitecollction.cs复制到您的项目中。
