Signalr-Core Hub中带有参数的构造函数 [英] constructor with parameters in a signalr-core hub

问题描述

我想在集线器中注入一些东西.

I would like to inject something into my hub.

基本上，我正在尝试等效于本教程 https://docs.microsoft.com/zh-cn/aspnet/signalr/overview/advanced/dependency-injection ，但适用于SignalR-Core.我对这部分最感兴趣

Basically I am trying to the equivalent of this tutorial https://docs.microsoft.com/en-us/aspnet/signalr/overview/advanced/dependency-injection, but for SignalR-Core. I am mostly interested in the part

public void Configuration(IAppBuilder app)
{
    GlobalHost.DependencyResolver.Register(
        typeof(ChatHub), 
        () => new ChatHub(new ChatMessageRepository()));

    App.MapSignalR();

    // ...
}

我该如何使用Net Core和SignalR-Core?

How do I do this Net Core and SignalR-Core?

推荐答案

在DI容器中使用以下方法注册您的 ChatMessageRepository :

Register your ChatMessageRepository in the DI container with:

services.AddTransient(typeof(ChatMessageRepository), typeof(ChatMessageRepository));

，然后在ctor中注入您的集线器:

and then inject into your hub in the ctor:

public ChatHub : Hub
{
    private readonly ChatMessageRepository _repository;
    public ChatHub(ChatMessageRepository repository)
    {
        _repository = repository;
    }
    ...
}
