TimeTrigger 异常“无法为 ScheduleMonitor 创建 BlobContainerClient。”

Question

当我使用 TimeTrigger 运行我的 azure 函数时，出现以下错误： Microsoft.Azure.WebJobs.Extensions.Timers.Storage：无法为 ScheduleMonitor 创建 BlobContainerClient。

我使用主机构建器：

public static async Task Main()
        {
            var host = CreateHostBuilder().Build();

            using (host)
            {
                await host.RunAsync();
            }

        static IHostBuilder CreateHostBuilder() => new HostBuilder()
            .UseServiceProviderFactory(new AutofacServiceProviderFactory())
            .ConfigureFunctionsWorkerDefaults()
            .ConfigureHostConfiguration(configHost =>
            {
                configHost.SetBasePath(Directory.GetCurrentDirectory());
                configHost.AddJsonFile("host.json", optional: true);
                configHost.AddEnvironmentVariables();
            })
            .ConfigureAppConfiguration((hostContext, configApp) =>
            {
                var env = hostContext.HostingEnvironment;
                configApp.AddJsonFile("appsettings.json", optional: true);
                configApp.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);
                configApp.AddEnvironmentVariables();
                configApp.AddApplicationInsightsSettings(developerMode: !env.IsProduction());
            })
            .ConfigureServices((hostContext, services) =>
            {
               [...]
            })
            .ConfigureContainer<ContainerBuilder>(builder =>
            {
                builder.RegisterModule<MessagerModule>();
            })
            .ConfigureLogging((hostContext, configLogging) =>
            {
                if (hostContext.HostingEnvironment.IsDevelopment())
                {
                    configLogging.AddConsole();
                    configLogging.AddDebug();
                }
            })
            .UseConsoleLifetime();

这是函数：

[Function("QueueMessage")]
        public async Task QueueMessageAsync(
            [TimerTrigger("%MessageQueuerOccurence%", RunOnStartup = true)] TimerInfo timer
        )
        {
           [...]
        }

项目：

<PropertyGroup>
        <TargetFramework>net6.0</TargetFramework>
        <AzureFunctionsVersion>v4</AzureFunctionsVersion>
        <OutputType>Exe</OutputType>
    </PropertyGroup>

    <ItemGroup>
        <Content Include="**\*.json" Exclude="bin\**\*;obj\**\*" CopyToOutputDirectory="Always" />
    </ItemGroup>
    
    <ItemGroup>
        <PackageReference Include="Autofac.Extensions.DependencyInjection" Version="7.2.0" />
        <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.20.0" />
        <PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Http" Version="3.0.13" />
        <PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Timer" Version="4.1.0" />

        <PackageReference Include="Microsoft.Azure.Functions.Worker" Version="1.6.0" />
        <PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="6.0.0" />
        <PackageReference Include="Microsoft.Extensions.Configuration.EnvironmentVariables" Version="6.0.0" />
    </ItemGroup>

本地.settings.json：

{ "IsEncrypted": false, "Values": { "AzureWebJobsStorage": "UseDevelopmentStorage=true", "MessageQueuerOccurence": "0 */15 * * * *", "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated" } }

我错过了什么？

我遇到这个问题是因为我没有运行存储模拟器......

一旦我安装并运行azurite，它就可以工作，这是正在维护的存储模拟器（Azure Storage Emulator已停止使用）。您可以在此处找到有关如何安装和使用它的更多信息。

我在 Mac OS 上使用 VS Code，我找到了在 VS Code 上安装azurite扩展的最简单的解决方案。安装后，我只需编辑扩展设置，即可设置该location设置（任何文件夹都可以）。之后，我可以从 VS Code 命令面板azurite运行开始。Azurite: Start

根据评论，可能还需要编辑local.settings.json文件并将AzureWebJobsStorage值更改为UseDevelopmentStorage=true.
