c# - Azure 函数(dotnet-isolated)无法启动，并出现 Grpc.Core.RpcException : StatusCode ="Unavailable" - Mac M1

Question

我最近获得了一台 Mac M1，并且正在设置我的计算机以进行 Azure Function(dotnet-isolated)开发。

我按照以下文档进行操作，该文档在我的 Windows 10 计算机上运行得非常好。 https://learn.microsoft.com/en-us/azure/azure-functions/create-first-function-cli-csharp?tabs=azure-cli%2Cisolated-process

以下是 Mac 中的设置，

% func --版本4.0.4895

% dotnet --list-sdks6.0.403 [/usr/local/share/dotnet/sdk]

% azure-functions-core-tools@4

% az --版本azure-cli 2.42.0

核心2.42.0遥测1.0.8

依赖关系:MSAL 1.20.0 azure 管理资源21.1.0b1

完成上述安装后，使用以下命令创建一个新函数

% func new --template "Http Trigger"--name MyHttpTrigger

然后当我尝试使用启动该功能时% 函数开始

我收到以下错误......

MyHttpTrigger: [GET,POST] http://localhost:7071/api/MyHttpTrigger
For detailed output, run func with --verbose flag.

请对我在这里缺少的内容有任何意见吗？

Answer 1

我知道这已经晚了，但是，我最近也遇到了这个问题，结果是我的 Program.cs 中的调用顺序问题。简而言之，我在 ConfigureAppConfiguration 之前调用了 ConfigureFunctionsWorkerDefaults。在这件事上，我用头撞墙的时间比我愿意承认的要长得多。一旦我改变了调用顺序，一切都很好。例如:

var host = new HostBuilder()
.ConfigureAppConfiguration(builder => builder.AddEnvironmentVariables())
.ConfigureFunctionsWorkerDefaults()
.Build();

希望这对其他人有帮助。
