调用 GetAzureADAppOnlyAuthenticatedContext 时无法加载文件或程序集“Microsoft.IdentityModel.Clients.ActiveDirectory”

Question

我正在使用证书在函数应用程序 (V1) 中获取 ClientContext 这是代码：

ClientContext newClientContext;
            try
            {
                newClientContext = new AuthenticationManager().GetAzureADAppOnlyAuthenticatedContext(SiteUrl, appId, tenant, certificate);
                newClientContext.ExecuteQuery();
                return newClientContext;
            }
            catch (Exception ex)
            {
                newClientContext = null;
                if (_logHelper != null)
                {
                    _logHelper.writeLog("GetAzureADContextError:"+ex.Message, TraceLevel.Error, ex);
                }
                return null;
            }

我的包裹是：

在本地visual studio环境下运行良好，但部署到应用服务后获取失败信息

Could not load file or assembly 'Microsoft.IdentityModel.Clients.ActiveDirectory, Version=2.29.0.1078, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Answer 1

关于错误，您的 Azure 函数中的 SDK SharePointPnPCoreOnline requests Microsoft.IdentityModel.Clients.ActiveDirectory 2.29.0.1078, but the sdk Microsoft.Azure.Services.AppAuthentication needs Microsoft.IdentityModel.Clients.ActiveDirectory version higher than 3.14.2. According to the situation, I suggest you use key vault reference。在我们这样做之后，我们可以删除 sdk Microsoft.Azure.Services.AppAuthentication 并将 sdk Microsoft.IdentityModel.Clients.ActiveDirectory 降级到版本 2.29。

详细步骤如下。

Configure MSI for Azure Function
为 Azure Function 应用程序标识创建一个 access policy in Key Vault
获取证书url

将 url 保存在 Azure function Application settings 中。它的甲酸盐应该像 @Microsoft.KeyVault(SecretUri=<your url>)

删除 SDK Microsoft.Azure.Services.AppAuthentication 并降级 SDK Microsoft.IdentityModel.Clients.ActiveDirectory
更新代码

 var s = Environment.GetEnvironmentVariable("cert");



            var cert = new X509Certificate2(Convert.FromBase64String(s),
                     (string)null,
                     X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable);
            try
            {
                using (var cc = new OfficeDevPnP.Core.AuthenticationManager().GetAzureADAppOnlyAuthenticatedContext(
                        SiteUrl, appId, tenant,
                        cert))
                {
                    cc.Load(cc.Web, p => p.Title);
                    cc.ExecuteQuery();
                    log.Info("Via PnP, we have site: " + cc.Web.Title);
                };
            }
            catch (Exception ex) {



                log.Info(ex.Message);
            }
