实际上，我收到 System.OutOfMemoryException for blob trigger azure function.Do I need to scale up or Scale out App Service Plan 来解决这个问题。

这两者有什么区别？

我们将Identity Server4与.NET Core结合使用，并将该应用程序部署为AWS无服务器lambda函数。当调用令牌端点以生成访问令牌时，我们收到以下错误消息：

{
"message": "Authorization header requires 'Credential' parameter. Authorization header requires 'Signature' parameter. Authorization header requires 'SignedHeaders' parameter. Authorization header requires existence of either a 'X-Amz-Date' or a 'Date' header. Authorization=Basic Y2xpZW50OnNlY3JldA=="

}

这是Identity Server应用程序中的ConfigurationServices方法：

 public void ConfigureServices(IServiceCollection services)
    {
        services.AddSingleton<IConfiguration>(Configuration);

        //connection string
        string connectionString = Configuration.GetConnectionString("IdentityServer");

        var rsaProvider = new RSACryptoServiceProvider(2048);

        SecurityKey key = new RsaSecurityKey(rsaProvider);

        var credentials = new Microsoft.IdentityModel.Tokens.SigningCredentials
              (key, SecurityAlgorithms.RsaSha256Signature);


        var migrationsAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;

        services.AddIdentityServer()
           .AddSigningCredential(credentials)
            // this adds the config data from DB …

我们正在使用EntityFrameworkCore与Identity Server4.初始设置后,身份server(localhost:6000/.well-known/openid-configuration)的发现端点工作正常.当我们尝试connect/token从邮递员调用端点时,它会给出400个错误的请求响应.这是我们的客户:

public static IEnumerable<Client> GetClients()
{
    return new List<Client>
    {
        new Client
        {
            ClientId = "client",

            // no interactive user, use the clientid/secret for authentication
            AllowedGrantTypes = GrantTypes.HybridAndClientCredentials,

            // secret for authentication
            ClientSecrets =
            {
                new Secret("secret".Sha256())
            },

            // scopes that client has access to
            AllowedScopes = { ApiResourceName.Sup_Api.Description() }
        },
        new Client
        {
            ClientId = "client2",

            // no interactive user, use the clientid/secret for authentication
            AllowedGrantTypes = GrantTypes.HybridAndClientCredentials,

            // secret for authentication
            ClientSecrets = …

我已经创建了 Http 触发器 Azure Function，其默认返回类型是Task<IActionResult>.

如果我改成有什么区别吗Task<HttpResponseMessage>？

具有返回类型的 Azure 函数Task<IActionResult>：

 public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "post", Route = null)] HttpRequest req,

Azure 函数具有Task<HttpResponseMessage>

 public static async Task<HttpResponseMessage> Run(
            [HttpTrigger(AuthorizationLevel.Function, "post", Route = null)]
            HttpRequestMessage message,

我正在尝试使用本地设置将新项目添加到 cosmos 数据库中。

这是我的批量插入代码：

private async Task AddSubscription(EnableOrDisableSubscriptionCommand command, SubscriptionAction subscriptionAction, IList<int> notificationCategoryTypes)
        {
            List<Task> bulkOperations = new List<Task>();
            foreach (var notificationCategory in notificationCategoryTypes)
            {
                var notificationTypes = Utility.GetNotificationTypes((NotificationCategoryType)notificationCategory);

                foreach (var notificationType in notificationTypes)
                {
                    foreach (var payerAccountSubscriptions in command.Subscriptions)
                    {
                        if (payerAccountSubscriptions.AccountNumbers?.Any() ?? false)
                        {
                            foreach (var accountNumber in payerAccountSubscriptions.AccountNumbers.Where(a => !string.IsNullOrEmpty(a)))
                            {
                                bulkOperations.Add(_repository.Create(subscriptionAction, notificationType,
                                      payerAccountSubscriptions.ColCoId, payerAccountSubscriptions.PayerNumber, accountNumber, command.UserRole,
                                      command.UserId));
                            }
                        }
                        else
                        {
                            bulkOperations.Add(_repository.Create(subscriptionAction, notificationType,
                                payerAccountSubscriptions.ColCoId, payerAccountSubscriptions.PayerNumber, null, command.UserRole,
                                command.UserId));

                        }
                    }
                }
            }
            await Task.WhenAll(bulkOperations);
        }
