我需要启动使用ASP.NET Core Web API进行通信的工作进程。我需要知道何时可以开始向该进程发送请求。到目前为止,我唯一看到的选择是让工作程序在完成父进程API的配置或通过“您还活着”请求轮询工作程序时进行调用。
是否有内置的机制?有更好的图案或设计吗?

通常,在成功启动应用程序之后,您将能够发送请求。
对于应用程序启动事件,您可以在.net core 3.0中尝试IHostApplicationLifetime
,如果使用的是以前的版本,则可以尝试IApplicationLifetime
,在以后的版本中将不再使用。
这是一个演示,用于在启动应用程序时注册事件。
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews().AddNewtonsoftJson();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env, IHostApplicationLifetime hostApplicationLifetime)
{
hostApplicationLifetime.ApplicationStarted.Register(() => {
Console.WriteLine("Application is Started");
});
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
// The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
});
}
}
