TimeTrigger异常“无法为ScheduleMonitor创建BlobContainerClient。

Question

当我使用TimeTrigger运行我的azure函数时，我遇到这个错误：Microsoft.Azure.WebJobs.Extensions.Timers.Storage：无法为SchrementMonitor创建BlobContainerClient。

我使用主机生成器：

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
        )
        {
           [...]
        }

csproj：

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

    <ItemGroup>
        <Content Include="**\*.json" Exclude="bin\**\*;obj\**\*" CopyToOutputDirectory="Always" />
    </ItemGroup>

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

local.settings.json

{ "IsEncrypted": false，" Values ":{ " azurewebjobstorage ":" UseDevelopmentStorage = true "，" MessageQueuerOccurence ":" 0 */15 * * * * "，" FUNCTIONS _ WORKER _ RUNTIME ":" dot net-isolated " } }

我错过了什么？

我遇到了这个问题，因为我没有运行存储模拟器...

一旦我安装并运行azurite，它就可以工作了，这是正在维护的存储模拟器（Azure存储资源管理器已停产）。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扩展的最简单解决方案。安装完成后，我只需要编辑扩展设置，以便设置位置设置（任何文件夹都应该有效）。之后，我能够通过运行Azurite：从VS Code命令面板开始来启动azourite。

根据注释，可能还需要编辑local.settings.json文件并将AzureWebJobStorage值更改为UseDevelopmentStorage=true。
