.netcore grpc客户端工厂及依赖注入使用

一、客户端工厂概述

gRPC 与 HttpClientFactory 的集成提供了一种创建 gRPC 客户端的集中方式。
可以通过依赖包Grpc.Net.ClientFactory中的AddGrpcClient进行gRPC客户端依赖注入
AddGrpcClient函数提供了许多配置项用于处理一些其他事项；例如AOP、重试策略等

二、案例介绍

创建一个WPF客户端
在App.xaml.cs代码类里重写OnStartup方法，进行依赖注入；需要注意的是在方法内设立窗口调用需要把展示端属性 xmlns: StartupUri="FieldWindow.xaml 给去掉
引用ServiceCollection做为容器集
注入gRPC工厂，注入windows窗体，以及其他需要用到的服务类等

三、客户端代码展示

proto文件可以看我之前的文章这里就不放上来了

    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            IServiceCollection services = new ServiceCollection();
            // 注入
            services.AddWPFGrpc();

            AddWPFWindows(services);
            // 构建服务提供器
            var serviceProvider = services.BuildServiceProvider();

            var fieldWindow = serviceProvider.GetRequiredService<FieldWindow>();

            fieldWindow.Show();
        }

        private IServiceCollection AddWPFWindows(IServiceCollection services)
        {
            if (services == null)
            {
                throw new ArgumentNullException(nameof(services));
            }

            var windowType = typeof(Window);
            var types = Assembly.GetExecutingAssembly().GetTypes().Where(t => t.BaseType == windowType).ToList();
            foreach (var type in types)
            {
                services.AddScoped(type);
            }

            return services;
        }
    }

    public static class GrpcClient
    {
        /// <summary>

        /// <returns></returns>
        public static IServiceCollection AddWPFGrpc(this IServiceCollection services)
        {
            if (services == null)
            {
                throw new ArgumentNullException(nameof(services));
            }
            services.AddGrpcClient<FieldRpc.FieldRpcClient>(options => options.Address = new Uri("https://localhost:7188"));

            return services;
        }
    }
