C# 如何使用.NET Core配置带有AWS Lambda函数的DI容器?
我想将DI容器连接到AWS lambda函数。如果有一个基类体系结构来促进AWS Lambda中的可靠原则,那就太好了。显然,没有startup.cs类或其他.NET核心初始化工具可用 这种方法将允许服务于更大的lambda函数的可测试部分C# 如何使用.NET Core配置带有AWS Lambda函数的DI容器?,c#,amazon-web-services,.net-core,aws-lambda,C#,Amazon Web Services,.net Core,Aws Lambda,我想将DI容器连接到AWS lambda函数。如果有一个基类体系结构来促进AWS Lambda中的可靠原则,那就太好了。显然,没有startup.cs类或其他.NET核心初始化工具可用 这种方法将允许服务于更大的lambda函数的可测试部分 public class Function : Startup { private IFooService _fooService; public Function(IFooService fooService) {

我一直在使用AutoFac执行此操作,每次函数调用都会创建一个新的作用域:
public class Functions
{
public static Lazy<ILifetimeScope> LifetimeScope { get; set; } = new Lazy<ILifetimeScope>(CreateContainer);
private static ILifetimeScope CreateContainer()
{
var containerBuilder = new ContainerBuilder();
containerBuilder.RegisterType<ServerAbc>()
.AsImplementedInterfaces();
return containerBuilder.Build();
}
/// <summary>
/// A Lambda function
/// </summary>
public async Task Handle(ILambdaContext context)
{
using (var innerScope = LifetimeScope.Value.BeginLifetimeScope())
{
var service = innerScope.Resolve<IServerAbc>();
await service.GoDoWork()
.ConfigureAwait(false);
}
}
}

也是这样,我可以在测试中模拟它
