 如何开发并一键发布WindowsService项目(netcore普通项目)

netcore下开发windows服务如果是web项目的话,由于aspnetcore本身是支持的,把默认的host.Run改为host.RunAsService就可以了。

但是普通的netcore的控制台项目我终于找到了如下方式来实现:

1. 打开vs 选择创建一个新的netcore 控制台项目

Nuget添加如下引用

  1. Microsoft.Extensions.Hosting
  2. System.ServiceProcess.ServiceController

新建一个ServiceBaseLifetime.cs 并将下面的内容复制进去

public class ServiceBaseLifetime : ServiceBase, IHostLifetime
{
private readonly TaskCompletionSource _delayStart = new TaskCompletionSource();

    public ServiceBaseLifetime(IApplicationLifetime applicationLifetime)
    {
        ApplicationLifetime = applicationLifetime ?? throw new ArgumentNullException(nameof(applicationLifetime));
    }

    private IApplicationLifetime ApplicationLifetime { get; }

    public Task WaitForStartAsync(CancellationToken cancellationToken)
    {
        cancellationToken.Register(() => _delayStart.TrySetCanceled());
        ApplicationLifetime.ApplicationStopping.Register(Stop);

        new Thread(Run).Start(); // Otherwise this would block and prevent IHost.StartAsync from finishing.
        return _delayStart.Task;
    }

    private void Run()
    {
        try
        {
            Run(this); // This blocks until the service is stopped.
            _delayStart.TrySetException(new InvalidOperationException("Stopped without starting"));
        }
        catch (Exception ex)
        {
            _delayStart.TrySetException(ex);
        }
    }

    public Task StopAsync(CancellationToken cancellationToken)
    {
        Stop();
        return Task.CompletedTask;
    }

    // Called by base.Run when the service is ready to start.
    protected override void OnStart(string[] args)
    {
        _delayStart.TrySetResult(null);
        base.OnStart(args);
    }

    // Called by base.Stop. This may be called multiple times by service Stop, ApplicationStopping, and StopAsync.
    // That's OK because StopApplication uses a CancellationTokenSource and prevents any recursion.
    protected override void OnStop()
    {
        ApplicationLifetime.StopApplication();
        base.OnStop();
    }
}

新建一个ServiceBaseLifetimeHostExtensions.cs 并将下面的内容复制进去

public static class ServiceBaseLifetimeHostExtensions
{
    public static IHostBuilder UseServiceBaseLifetime(this IHostBuilder hostBuilder)
    {
        return hostBuilder.ConfigureServices((hostContext, services) => services.AddSingleton<IHostLifetime, ServiceBaseLifetime>());
    }

    public static void RunAsService(this IHostBuilder hostBuilder)
    {
        hostBuilder.UseServiceBaseLifetime().Build().Run();
    }

    public static Task RunAsServiceAsync(this IHostBuilder hostBuilder)
    {
        return hostBuilder.UseServiceBaseLifetime().Build().RunAsync(CancellationToken.None);
    }
}

新建一个服务类 TestService.cs 并写入以下内容(该服务就是每1秒往d:\log.txt写入当前时间)

public class TestService: IHostedService,IDisposable
{
readonly System.Timers.Timer tmBak = new System.Timers.Timer();

    public TestService()
    {
        tmBak.Interval = 1000;//1秒执行1次
        tmBak.AutoReset = true;//执行1次false,一直执行true
        tmBak.Enabled = true;
        tmBak.Elapsed += (sender, eventArgs) =>
        {
            using (StreamWriter sw = new StreamWriter("D:\\log.txt",true))
            {
                sw.WriteLine($"AntDeploy Windows服务:{DateTime.Now:yyyy-MM-dd HH:mm:ss}");
            }
        };
    }


    public Task StartAsync(CancellationToken cancellationToken)
    {
        tmBak.Start();
        return Task.CompletedTask;
    }

    public Task StopAsync(CancellationToken cancellationToken)
    {
        tmBak.Stop();
        return Task.CompletedTask;
    }

    public void Dispose()
    {
        this.tmBak.Dispose();
    }
}

编辑 Program.cs 写入如下内容,保证既可以作为控制台打开又可以作为windows服务运行:

class Program
{
// P/Invoke declarations for Windows.
[DllImport("kernel32.dll")] static extern IntPtr GetConsoleWindow();
[DllImport("user32.dll")] static extern bool IsWindowVisible(IntPtr hWnd);
public static bool HaveVisibleConsole()
{
return RuntimeInformation.IsOSPlatform(OSPlatform.Windows) ?
IsWindowVisible(GetConsoleWindow())
:
Console.WindowHeight > 0;
}

    private static async Task Main(string[] args)
    {
        var pathToExe = Process.GetCurrentProcess().MainModule.FileName;
        var pathToContentRoot = Path.GetDirectoryName(pathToExe);
        Directory.SetCurrentDirectory(pathToContentRoot);

        var isService = !(Debugger.IsAttached || args.Contains("--console"));

        if (HaveVisibleConsole()) isService = false;
        var builder = new HostBuilder()
            .ConfigureServices((hostContext, services) =>
            {
                services.AddHostedService<TestService>();
            });

        if (isService)
        {
            await builder.RunAsServiceAsync();
        }
        else
        {
            await builder.RunConsoleAsync();
        }
    }
}

一键发布到服务器,在工程上点击右键 然后选择 AntDeploy

AntDeploy是我开发的一款开源一键部署vs插件(也是支持脱离vs单独使用的一个开源工具)

开源地址:https://github.com/yuzd/AntDeployAgent

配置AntDeploy

添加一个环境 名字叫 测试 然后 在 测试环境里面添加 windows服务器 这里我做测试就添加就是我本机,注意Host里面是填写格式为:ip:端口号

 注意:Token不是windows服务器的密码!!!是安装agent后,agent的配置文件里面配置的Token(你自己自定义配置的)
注意:Port不是你要发布的项目的端口号!!!是安装agent后,agent的配置文件里面配置的端口号(你自己自定义配置的)
点击【Connect Test】按钮进行确认agent可以成功链接,否则会发布失败
如果【Connect Fail】失败 请查看 #10

进入 WindowsService Tab界面

Sdk类型选择 netcore
ServiceName 填写上面我们设置的名称:[TestService]

点击 【Deploy】按钮进行发布

确认服务器无误 点击 【是】开始执行一键部署
如果发布出现错误会出现下图所示:

可以在Log里面查看失败原因是因为我部署agent没有用管路员权限 报权限不足失败 需要用管理员权限运行agent才行

 部署成功 如下图:

 查看D盘下是否log.txt是否正常每隔1秒写入了当前时间

这里演示的是windows服务上没有这个service
所以自动创建了。
如果service已存在的情况 Deploy 就会全量覆盖 不会重新创建site的。
如果想要覆盖时排除指定文件 可以在 Setting Tab界面的IgnoreList里面增加(支持正则)
