NET 5.0独立Azure函数未激发代码-超时

Question

引用这些指令：

功能-单网-5

独立功能

我创建了一个。NET 5.0的隔离函数，最初一切看起来都还可以。当我运行它时，它只会超时：

它检测到函数并触发，但实际函数没有运行(调试器没有附加(。

[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 blobn 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));
}

和启动(调试器确实连接正常(：

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试试吗？

进程外意味着您的函数主机和运行时在不同的进程中运行，因此您必须将调试器附加到进程以进行调试。

1. 在Visual Studio中，在函数项目的csproj的属性上设置此参数来运行函数(这样做很方便，这样您就不必在将来的运行中重复该命令(：

主机启动--dotnet隔离调试--详细

你可以在VS中通过右键单击项目来做到这一点>属性>调试>Application Arguments，并将此命令粘贴到那里(或者，在命令行中，cd到函数项目中，然后运行相同的命令，再加上命令开头的关键字func(。

2. 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或按启动

3. 接下来，您等待函数运行，并在函数的控制台中显示进程ID(PID(。收到。

4. 返回VS，点击Ctrl+Alt+p附加到进程(搜索dotnet以筛选出其他机器进程(

在此之后，您将立即看到函数反应，表示它已附加到进程。现在您可以调试了。这将阻止函数在本地计算机上超时，并在函数执行路径中需要的任何断点处停止。干杯=(
