abp 在 .net core web 应用中接管请求

abp里面每个中间件都可以配置自己的依赖注入容器(重写 ConfigureServices ，然后通过上下文的 Services 属性获取ioc容器)和请求管道（重写 OnApplicationInitialization，然后通过上下文的GetApplicationBuilder 获取 applicationBuilder）

    [DependsOn(typeof(AbpAspNetCoreMvcModule))]    public class App1Module : AbpModule    {        // 这里配置模块自己的容器        public override void ConfigureServices(ServiceConfigurationContext context)        {            IServiceCollection services = context.Services;            //services.AddTransient<IService1, Service1>();            base.ConfigureServices(context);        }        // 这里配置模块自己的管道        public override void OnApplicationInitialization(ApplicationInitializationContext context)        {            var app = context.GetApplicationBuilder();            app.UseRouting();            app.UseEndpoints(endpoint => {                endpoint.MapGet("/guid", async context => {                    await context.Response.WriteAsync(Guid.NewGuid().ToString());                });            });            base.OnApplicationInitialization(context);        }    }

项目结构图

1 创建 asp.net core mvc 项目，添加 Volo.Abp.AspNetCore.Mvc 包

项目Module类如下：

using ClassLibrary1;using Microsoft.AspNetCore.Builder;using Microsoft.Extensions.Hosting;using Volo.Abp;using Volo.Abp.AspNetCore.Mvc;using Volo.Abp.Modularity;namespace AbpHelloworldWebMvc{    [DependsOn(typeof(AbpAspNetCoreMvcModule))]    [DependsOn(typeof(App1Module))]    public class AbpHelloworldWebMvcModule : AbpModule    {        // 在模块里面写自己的管道        public override void OnApplicationInitialization(ApplicationInitializationContext context)        {            var app = context.GetApplicationBuilder();            var env = context.GetEnvironment();            if (env.IsDevelopment())            {                app.UseDeveloperExceptionPage();            }            else            {                app.UseExceptionHandler("/Home/Error");            }            app.UseStaticFiles();            app.UseRouting();            app.UseAuthorization();            // 使用 abp 的扩展方法配置默认路由            app.UseConfiguredEndpoints(options => {                options.MapControllerRoute("default", "{controller=Home}/{action=privacy}/{id?}");            });        }    }}

Startup类如下：

using Microsoft.AspNetCore.Builder;using Microsoft.AspNetCore.Hosting;using Microsoft.Extensions.Configuration;using Microsoft.Extensions.DependencyInjection;using Microsoft.Extensions.Hosting;using System;using System.Collections.Generic;using System.Linq;using System.Threading.Tasks;namespace AbpHelloworldWebMvc{    public class Startup    {        // This method gets called by the runtime. Use this method to add services to the container.        public void ConfigureServices(IServiceCollection services)        {            services.AddApplication<AbpHelloworldWebMvcModule>();        }        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.        public void Configure(IApplicationBuilder app)        {            app.InitializeApplication();        }    }}

2 创建项目 ClassLibrary1

模块类如下：

using Microsoft.AspNetCore.Builder;using Microsoft.AspNetCore.Http;using Microsoft.Extensions.DependencyInjection;using System;using Volo.Abp;using Volo.Abp.AspNetCore.Mvc;using Volo.Abp.Modularity;namespace ClassLibrary1{    [DependsOn(typeof(AbpAspNetCoreMvcModule))]    public class App1Module : AbpModule    {        // 这里配置模块自己的容器        public override void ConfigureServices(ServiceConfigurationContext context)        {            IServiceCollection services = context.Services;            //services.AddTransient<IService1, Service1>();            base.ConfigureServices(context);        }        // 这里配置模块自己的管道        public override void OnApplicationInitialization(ApplicationInitializationContext context)        {            var app = context.GetApplicationBuilder();            app.UseRouting();            app.UseEndpoints(endpoint => {                endpoint.MapGet("/guid", async context => {                    await context.Response.WriteAsync(Guid.NewGuid().ToString());                });            });            base.OnApplicationInitialization(context);        }    }}

添加服务 IService1

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using Volo.Abp.DependencyInjection;namespace ClassLibrary1{    public interface IService1         : ITransientDependency    {        string Ping();    }    public class Service1 : IService1    {        public string Ping()        {            return "App1 Pong";        }    }}

在项目 ClassLibrary1 添加控制器 App1Controller

using Microsoft.AspNetCore.Mvc;using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using Volo.Abp.AspNetCore.Mvc;namespace ClassLibrary1{    public class App1Controller : AbpController    {        IService1 _service1;        public App1Controller(IService1 service1)        {            _service1 = service1;        }        public IActionResult Ping()        {            var resStr = _service1.Ping();            return Content(resStr);        }    }}

3 测试

这时 web 项目为启动页

输入一下两个地址，访问 App1Module 里面配置的控制器和管道

http://localhost:5000/app1/ping

http://localhost:5000/guid
