我创建了一个 .NET 5.0 独立函数，最初一切正常。当我运行它时，它只是超时:

它检测到函数并触发触发器，但实际函数未运行(调试器未附加)。

[Function(nameof(MediaUploadProcessorFunction))]
public async Task Run([BlobTrigger(containerName + "/{name}", Connection = "AzureWebJobsStorage")] Stream myBlob, string name, ILogger log)
{
    System.Diagnostics.Debugger.Launch();
    System.Diagnostics.Debugger.Break();

    log.LogInformation($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");
}

public MediaUploadProcessorFunction(IEmailService emailService, IMediaRepository mediaRepository, IOptions<ErrorEmailOptions> errorEmailOptions, IOptions<ValuesOptions> valuesOptions, IGroupRepository groupRepository)
{
    System.Diagnostics.Debugger.Launch();
    System.Diagnostics.Debugger.Break();

    _emailService = emailService ?? throw new ArgumentNullException(nameof(emailService));
    _mediaRepository = mediaRepository ?? throw new ArgumentNullException(nameof(mediaRepository));
    _errorEmailOptions = errorEmailOptions?.Value ?? throw new ArgumentNullException(nameof(errorEmailOptions));
    _values = valuesOptions?.Value ?? throw new ArgumentNullException(nameof(valuesOptions));
    _groupRepository = groupRepository ?? throw new ArgumentNullException(nameof(groupRepository));
}

启动(调试器确实附加正常):

static Task Main(string[] args)
{
    System.Diagnostics.Debugger.Launch();

    var config = new ConfigurationBuilder()
        .SetBasePath(Directory.GetCurrentDirectory())
        .AddJsonFile("local.settings.json", optional: true, reloadOnChange: true)
        .AddEnvironmentVariables()
        .Build();

    var host = new HostBuilder()
        .ConfigureAppConfiguration(configurationBuilder =>
        {
            configurationBuilder.AddCommandLine(args);
        })
        .ConfigureFunctionsWorkerDefaults()
        .ConfigureServices(services =>
        {
            services.AddLogging();

            services.Configure<ValuesOptions>(config.GetSection("Values"));
            services.AddScoped<IMediaRepository, MediaRepository>();
            services.Configure<ErrorEmailOptions>(config.GetSection("ErrorEmail"));
            services.AddScoped<IEmailService, EmailService>();
            services.AddScoped<IGroupRepository, GroupRepository>();

            services.AddDbContext<Context>(opts =>
            {
                var conn = config.GetConnectionString("Context");
                opts.UseSqlServer(conn);
            });
        })
        .Build();

    return host.RunAsync();
}

有人有什么想法我可以尝试吗？

进程外意味着您的函数宿主和运行时运行在不同的进程中，因此您必须将调试器附加到进程中才能进行调试。

1. 在 Visual Studio 中，使用在保存该函数的函数项目 csproj 的属性上设置的此参数来运行函数(这样做很方便，这样您就不必在以后的运行中重复该命令):

主机启动 --dotnet-isolated-debug --verbose

您可以在 VS 中执行此操作，方法是右键单击项目 > 属性 > 调试 > 应用程序参数，然后将此命令粘贴到此处(或者，在命令行中，cd 进入函数项目并运行相同的命令加上关键字命令开头的 func)。

将函数项目作为启动项目运行。右键单击功能项目 > 设置为启动。然后使用 f5 或按开始

接下来等待函数运行并在函数的控制台中显示进程 ID (PID)。复制该内容。

返回 VS，点击 Ctrl + Alt + P 附加到进程(搜索dotnet以过滤掉其他机器进程)

在此之后，您将立即看到该函数使用react，表示它附加到了一个进程。现在你可以调试了。这应该会阻止函数在本地计算机上超时，并在函数执行路径中所需的任何断点处停止。干杯=)
