服务结构不止一个用于服务远程的通信侦听器 [英] Service fabric more than one communication listener for service remoting

问题描述

我正在使用Azure Service Fabric开发一些微服务.我有一些用例需要微服务之间的通信，并且阅读了有关服务远程处理的信息

I am developing few micro services using Azure Service Fabric. I have some use cases which need the communication between micro services and I read about service remoting https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-reliable-services-communication-remoting. I just wanted to know is it possible to support more than one listeners in a SF application. E.g. I have an existing stateless web api SF application which is having a listener like below

protected override IEnumerable<ServiceInstanceListener> CreateServiceInstanceListeners()
    {
        return new ServiceInstanceListener[]
        {
            new ServiceInstanceListener(serviceContext => new OwinCommunicationListener(Startup.ConfigureApp, serviceContext, ServiceEventSource.Current, "ServiceEndpoint"))
        };
    }

在上面的列表中，我需要添加一个ServiceRemotingListener，以便可以为其他人公开一些来自Micro服务的数据.方法是否可能或有任何错误.我已经完成了基于反向代理的通信，但是有点担心性能(因为我计划执行从服务1到服务2的实时读取操作).

To the above list, I need to add a ServiceRemotingListener so that I can expose some data from Micro service for others. Is it possible or anything wrong with approach. I have done the Reverse proxy based communication, but bit concerned with the performance(since I am planning to perform a real time read operation from Service 1 to Service 2).

推荐答案

在您的CreateServiceInstanceListeners方法中，您将返回一个侦听器数组.这意味着可以创建多个侦听器.只需像添加其他数组一样添加它即可:

In your CreateServiceInstanceListeners method you are returning an array of listeners. This means that it is possible to create multiple listeners. Just add it like you would with any other array:

protected override IEnumerable<ServiceInstanceListener> CreateServiceInstanceListeners()
{
    return new ServiceInstanceListener[]
    {
        new ServiceInstanceListener(serviceContext => this.CreateServiceRemotingListener(serviceContext), "RemotingListener"),
        new ServiceInstanceListener(serviceContext => new OwinCommunicationListener(Startup.ConfigureApp, serviceContext, ServiceEventSource.Current, "ServiceEndpoint"))
    };
}

请注意，即使侦听器名称是可选参数，您也必须必须为侦听器命名.服务代理尝试连接到另一个端点时，我也遇到了一些问题.为了解决此问题，请首先声明远程侦听器，然后再声明其他侦听器.

Note that even though the listener name is an optional parameter, you have to give your listeners a name. I've also experienced some problems with the service proxy trying to connect to the other endpoint. In order to solve this declare the remoting listener first and your other listeners second.
