ASP.NET Core中的ConfigureServices()和Configure()之间有什么区别? [英] What are the differences between ConfigureServices() and Configure() in ASP.NET Core?

问题描述

docs.microsoft.com上的文档规定以下内容:

The documentation on docs.microsoft.com states the following:

使用ConfigureServices方法将服务添加到容器中.

Use ConfigureServices method to add services to the container.

使用Configure方法配置HTTP请求管道.

Use Configure method to configure the HTTP request pipeline.

有人可以用简单的例子来说明，向容器添加服务是什么意思，以及配置HTTP请求管道是什么意思?

Can someone explain with simple examples, what is meant by adding services to container and what is meant by configuring HTTP request pipeline?

推荐答案

简而言之:

ConfigureServices用于配置依赖注入

public void ConfigureServices(IServiceCollection services)
{
    // register MVC services
    services.AddMvc();

    // register configuration
    services.Configure<AppConfiguration>(Configuration.GetSection("RestCalls")); 

    // register custom services
    services.AddScoped<IUserService, UserService>();
    ...
}

Configure用于设置中间件，路由规则等

Configure is used to set up middlewares, routing rules, etc

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    // configure middlewares
    app.UseMiddleware<RequestResponseLoggingMiddleware>();
    app.UseMiddleware<ExceptionHandleMiddleware>();

    app.UseStaticFiles();

    // setup routing
    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "Default",
            template: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = 1 });

    });
}
