带Azure功能的温莎城堡(v3)

Question

我要绕着这个圈子转。有什么方法可以使用Castle Windsor依赖项注入适配器吗(https://github.com/volosoft/castle-windsor-ms-adapter)使用Azure Function应用程序？

适配器github页面上的代码示例是针对ASP.NET Core的，但我想也有一种方法可以指定函数应用程序使用的服务提供商？

没有关于这方面的官方文件，但DavidJFowler 提出了一个功能请求

请从上述功能请求中找到示例代码。

IJobActivatorEx实现：

public class CastleWindsorJobActivator : IJobActivatorEx
{
private readonly WindsorContainer container;
public CastleWindsorJobActivator(WindsorContainer container) => this.container = container;
public T CreateInstance<T>(IFunctionInstanceEx functionInstance)
{
var disposer = functionInstance.InstanceServices.GetRequiredService<ScopeDisposable>();
disposer.Scope = container.BeginScope();
return container.Resolve<T>();
}
// Ensures a created Castle.Windsor scope is disposed at the end of the request
public sealed class ScopeDisposable : IDisposable
{
public IDisposable Scope { get; set; }
public void Dispose() => this.Scope?.Dispose();
}
public T CreateInstance<T>()
{
var disposer = container.Resolve<ScopeDisposable>();
disposer.Scope = container.BeginScope();
return container.Resolve<T>();
}
}

启动类别：

[assembly: FunctionsStartup(typeof(FunctionApp2.Startup))]
namespace FunctionApp2
{
public class Startup: FunctionsStartup
{
public override void Configure(IFunctionsHostBuilder builder)
{
var container = new WindsorContainer();
container.Register(Component.For<IScoped1>().ImplementedBy<Scoped1>().LifestyleScoped())
.Register(Component.For<IScoped2>().ImplementedBy<Scoped2>().LifestyleScoped())
.Register(Component.For<ISingleton1>().ImplementedBy<Singleton1>())
.Register(Component.For<ISingleton2>().ImplementedBy<Singleton2>());
// register function classes in container
var functions = Assembly.GetExecutingAssembly().GetTypes().Where(t =>
t.GetMethods().Any(m => m.GetCustomAttributes(typeof(FunctionNameAttribute), false).Any()));
foreach (var function in functions)
{
container.Register(Component.For(function).LifestyleScoped());
}
builder.Services.AddScoped<CastleWindsorJobActivator.ScopeDisposable>()
.AddSingleton<IJobActivator>(new CastleWindsorJobActivator(container));
container.AddServices(builder.Services);
}
}
}

示例函数：

public class Function1
{
public Function1(IScoped1 scoped1, IScoped2 scoped2, ISingleton1 singleton1, ISingleton2 singleton2)
{

}
[FunctionName("Function1")]
public async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
string name = req.Query["name"];
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
name = name ?? data?.name;
return name != null
? (ActionResult)new OkObjectResult($"Hello, {name}")
: new BadRequestObjectResult("Please pass a name on the query string or in the request body");
}
}

目前，此功能尚未正式发布，但您可以遵循其他依赖注入模式。您可以从Microsoft QnA或Azure门户提出功能请求。
