使用Topshelf部署.net core windows服务

首先新建一个.net core的模板worker程序

过程 略

打开Program.cs

namespace TopshelfDemo{ public class Program {  public static void Main(string[] args)  {   CreateHostBuilder(args).Build().Run();  }  public static IHostBuilder CreateHostBuilder(string[] args) =>   Host.CreateDefaultBuilder(args)    .ConfigureServices((hostContext, services) =>    {     services.AddHostedService<Worker>();    }); }}

nuget 安装Topshelf

略

改写下Program.cs

 public class Program {  public static void Main(string[] args)  {   HostFactory.Run(x =>   {    x.Service<IHost>(s =>    {     s.ConstructUsing(() => CreateHostBuilder(args).Build());     s.WhenStarted(service =>     {      service.Start();     });     s.WhenStopped(service =>     {      service.StopAsync();     });    });    x.StartAutomatically();    x.RunAsLocalSystem();    x.SetServiceName("TopshelfDemo.ServiceName");    x.SetDisplayName("TopshelfDemo.DisplayName");    x.SetDescription("TopshelfDemo.Description");   });  }  public static IHostBuilder CreateHostBuilder(string[] args) =>   Microsoft.Extensions.Hosting.Host.CreateDefaultBuilder(args)    .ConfigureServices((hostContext, services) =>    {     services.AddHostedService<Worker>();    }); }

该写法的实现原理：通过通用主机方法 IHost 实现管理主机生存期

写法如下：

public class Program{ private IHost _host; public Program() {  _host = new HostBuilder()   .Build(); } public async Task StartAsync() {  _host.StartAsync(); } public async Task StopAsync() {  using (_host)  {   await _host.StopAsync(TimeSpan.FromSeconds(5));  } }}

打包

安装 TopshelfDemo

找到相应的文件夹
TopshelfDemo.exe install

启动 TopshelfDemo

TopshelfDemo.exe start

卸载 TopshelfDemo

TopshelfDemo.exe uninstall

.NET 通用主机通用配置

配置Configuration

Host.CreateDefaultBuilder(args) .ConfigureHostConfiguration(configHost => {  configHost.SetBasePath(Directory.GetCurrentDirectory());  configHost.AddJsonFile("hostsettings.json", optional: true);  configHost.AddEnvironmentVariables(prefix: "PREFIX_");  configHost.AddCommandLine(args); });

环境名称

Host.CreateDefaultBuilder(args) .UseEnvironment("Development") //...

logging引入

    .ConfigureLogging((context, logger) =>    {     logger.AddConsole();     //logger.AddLog4Net();     logger.SetMinimumLevel(LogLevel.Information);    })

依赖注入

 public class ToDoWork {  public string TimeNow()  {   return DateTime.Now.ToString();  } }program.cs    .ConfigureServices((hostContext, services) =>    {     services.AddScoped<ToDoWork>();     services.AddHostedService<Worker>();    });

program.cs 最终如下

using System.IO;using Microsoft.Extensions.Configuration;using Microsoft.Extensions.DependencyInjection;using Microsoft.Extensions.Hosting;using Microsoft.Extensions.Logging;using Topshelf;namespace TopshelfDemo{ public class Program {  public static void Main(string[] args)  {   HostFactory.Run(x =>   {    x.Service<IHost>(s =>    {     s.ConstructUsing(() => CreateHostBuilder(args).Build());     s.WhenStarted(service =>     {      service.Start();     });     s.WhenStopped(service =>     {      service.StopAsync();     });    });    x.StartAutomatically();    x.RunAsLocalSystem();    x.SetServiceName("TopshelfDemo.ServiceName");    x.SetDisplayName("TopshelfDemo.DisplayName");    x.SetDescription("TopshelfDemo.Description");   });  }  public static IHostBuilder CreateHostBuilder(string[] args) =>   Microsoft.Extensions.Hosting.Host.CreateDefaultBuilder(args)    .UseEnvironment(Environments.Development)    //.UseEnvironment(Environments.Production)    //.UseEnvironment(Environments.Staging)    .ConfigureHostConfiguration(configHost =>    {     configHost.SetBasePath(Directory.GetCurrentDirectory());     configHost.AddJsonFile("hostsettings.json", optional: true);     configHost.AddEnvironmentVariables(prefix: "PREFIX_");     configHost.AddCommandLine(args);    })    .ConfigureLogging((context, logger) =>    {     logger.AddConsole();     //logger.AddLog4Net();     logger.SetMinimumLevel(LogLevel.Information);    })    .ConfigureServices((hostContext, services) =>    {     services.AddScoped<ToDoWork>();     services.AddHostedService<Worker>();    }); }}
