我需要与多个远程演员系统进行通信 [英] I need to communicate with multiple remote actor systems

问题描述

林用akka.Net开发一个插件架构即包含一个或多个插件每个DLL加载到自己的的AppDomain玩和新的演员系统初始化准备从主机收到消息。

Im playing with using akka.Net to develop a plugin architecture whereby each dll that contains one or more plugins is loaded into its own AppDomain and a new actor system is initialized ready to recieve messages from the "Host".

我成为脱胶试图让这个与多个插件工作。

I become unstuck trying to get this to work with multiple plugins.

所以主机的配置如下：

akka {
    actor {
        provider = ""Akka.Remote.RemoteActorRefProvider, Akka.Remote""
    }
    remote {
        helios.tcp {
            transport-class = ""Akka.Remote.Transport.Helios.HeliosTcpTransport, Akka.Remote""
            applied-adapters = []
            transport-protocol = tcp
            port = 50003
            hostname = localhost
        }
    }
}

和插件的配置如下：

akka {
    actor {
        provider = ""Akka.Remote.RemoteActorRefProvider, Akka.Remote""
    }
    remote {
        helios.tcp {
            transport-class = ""Akka.Remote.Transport.Helios.HeliosTcpTransport, Akka.Remote""
            applied-adapters = []
            transport-protocol = tcp
            port = 50004
            hostname = localhost
    }
}

（有许多这样的）

我的问题是我如何得到主机的消息给所有的插件？

My question is how do i get messages from the Host to all of the plugins?

推荐答案

最好的建议是使用Akka.Cluster。这里有一个证据充分的例子： https://github.com/petabridge/akkadotnet-code -samples /树/主/ Cluster.WebCrawler

The best recommendation is to use Akka.Cluster. Here's a well-documented example: https://github.com/petabridge/akkadotnet-code-samples/tree/master/Cluster.WebCrawler

让每个插件配置使用动态端口（ akka.remote.helios。 tcp.port = 0 ），然后定义一个集群路由器会谈演员系统履行特定角色。

Have each plugin config use a dynamic port (akka.remote.helios.tcp.port = 0) and then define a clustered router that talks to actor systems fulfilling specific roles.

/api/broadcaster {
  router = broadcast-group
  routees.paths = ["user/api"]
  cluster {
      enabled = on
      max-nr-of-instances-per-node = 1
      allow-local-routees = on
      use-role = crawler
  }
}

这路由器，部署在路径用户/ API /广播上的一些节点进行通信（通过广播路由策略）与作用在集群中部署在路径用户/ API 的任何节点上的任何演员履带无需查找IP地址，端口，或任何废话。

This router, deployed at the path user/api/broadcaster on some node can communicate (via the Broadcast routing strategy) with any actor deployed at path user/api on any node in the cluster with role crawler without needing to look up IP addresses, ports, or any of that crap.

您配置一个节点的集群通过在Akka.NET的配置以下部分的信息：

You configure a node's clustering information via the following section in Akka.NET's config:

cluster {
  #manually populate other seed nodes here, i.e. "akka.tcp://lighthouse@127.0.0.1:4053"
  seed-nodes = ["akka.tcp://webcrawler@127.0.0.1:4053"]
  roles = [crawler]
}

种子节点 - 已成为一个众所周知的，静态定义的端口和IP地址。阅读的文章为什么这是很重要的一个解释

Seed nodes - has to be a well-known, statically-defined port and IP address. Read the article for an explanation on why this is important.

角色 - 定义了这个特殊的节点的能力是逗号分隔字符串。它们更像是标签。您可以使用它们集群路由器内部（如我之前展示）阐明你想与之通信的类型的节点。

Roles - comma-delimited strings that define what this particular nodes' capabilities are. They're more like tags. You can use them inside clustered routers (like the one I showed earlier) to articulate which types of nodes you want to communicate with.
