net core 在windows 下部署服务

参考来源 https://www.jb51.net/article/265865.htm

首先要 指定配置文件，否则运行的时候找不到appsettings.json ,

在使用 sc create 创建 Windows 服务时，确实存在一个问题，即服务的默认工作目录是 C:\Windows\System32，而不是服务的可执行文件所在的目录。这就是为什么你的服务找不到 appsettings.json 文件的原因。

然后要安装 依赖 Microsoft.Extensions.Hosting.WindowsServices包

示例代码如下

using System.Diagnostics;
using System.Reflection;
using System.Text.Json.Serialization;
using ApiHelper.ext;
using ApiHelper.middleware;
using Microsoft.EntityFrameworkCore;
using pointserver.api;
using pointserver.dbcontext;
using pointserver.impl;
using pointserver.lifecycle;
using TDEngineHelper;

var assemblyName = Assembly.GetExecutingAssembly().GetName().Name;
var scCMD = $"sc create {assemblyName} binpath= \"{Process.GetCurrentProcess().MainModule!.FileName}\" start= auto";
Console.WriteLine($"创建服务语句为 {scCMD}");


var builder = WebApplication.CreateBuilder(args);

IConfiguration configuration = null; //so it can be used on other configuration functions bellow


var baseDirectory = AppContext.BaseDirectory;
//load config file, build it, give it to WebApplication and keep the config variable for further use.
// 必须指定配置文件，否则做成服务 读取不到配置文件
builder.WebHost.ConfigureAppConfiguration(
    (hostingContext, config) =>
    {
        var path = Path.Combine(baseDirectory,builder.Environment.IsDevelopment()?"appsettings.Development.json"
            : "appsettings.json");
        config.AddJsonFile(path, optional: false, reloadOnChange: true);
        config.AddEnvironmentVariables();
        configuration = config.Build();
    });
Console.WriteLine($"当前工作目录为 {baseDirectory}, 将其设置为配置文件目录");
builder.Configuration.SetBasePath(baseDirectory); // 设置配置文件路径 不加这行，sc 创建服务 默认工作目录是 C:\Windows\System32 会找不到配置文件
builder.UseLog();

var mysqlConnectionString = builder.Configuration["ConnectionStrings:MySQL"];
Console.WriteLine($"mysql 连接字符串为 {mysqlConnectionString}");
var tdEngineHost = builder.Configuration.GetConnectionString("TDEngineHost");
var tdEnginePort = builder.Configuration.GetConnectionString("TDEnginePort");
var tdEngineUser = builder.Configuration.GetConnectionString("TDEngineUser");
var tdEnginePass = builder.Configuration.GetConnectionString("TDEnginePassword");
var tdEngineDb = builder.Configuration.GetConnectionString("TDEngineDatabase");
// port to short 
short.TryParse(tdEnginePort, out var tdEnginePortShort);



// Add services to the container.


builder.Services.AddControllers()
    .AddJsonOptions(x => x.JsonSerializerOptions.ReferenceHandler = ReferenceHandler.IgnoreCycles); // 防止Json 循环引用

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
builder.Services.AddScoped<IPointRepo, PointRepo>();
builder.Services.AddScoped<IPointGroupRepo, PointGroupRepo>();
builder.Services.AddScoped<IPointGroupRltPointRepo, PointGroupRltPointRepo>();
builder.Services.AddScoped<IUnitRepo, UnitRepo>();
builder.Services.AddScoped<ISystemRepo, SystemRepo>();
builder.Services.AddSingleton<IHostedService, HostService>(); // 程序启停服务 
// tdEngine service 依赖注入
builder.Services.AddSingleton<ITDEngineRepo>(new TDEngineRepo(tdEngineHost, tdEngineUser, tdEnginePass, tdEngineDb,
    tdEnginePortShort));


builder.Services.AddDbContext<PointServerDbContext>();
builder.Services.AddAutoMapper(AppDomain.CurrentDomain.GetAssemblies());

builder.Services.AddWindowsService(o => { o.ServiceName = assemblyName; }); // 必须加上这个，不然报错  windows 无法启动pointsrever 服务 错误 1053 ： 服务没有及时响应启动或控制请求 
var app = builder.Build();

app.UseCustomExceptionHandler(); // 异常中间件

app.UseSwagger();
app.UseSwaggerUI();
// 允许所有跨域
app.UseCors(x => x
    .AllowAnyMethod()
    .AllowAnyHeader()
    .SetIsOriginAllowed(origin => true) // allow any origin
    .AllowCredentials());

app.UseStaticFiles();

app.MapControllers();


app.Run();
