先进行配置

首先这种需求，一般发生在APP端，我们给APP，不会给所有项目系统的接口给他们用。我们系统有200个接口，但是APP的需求只会用20个。那么这个需求也就应运而生了。

项目结构.png

以上为API文件夹中为项目接口，没有啥特别复杂的东西存在。

首先创建好，一个网站项目，进行模块的配置。
首先引入以下的nuget包：
以下是WebApp项目中的packages.config

</packages>

新建一个'AbpProjectTemplateWebAppModule.cs' 的类文件：

  [DependsOn(
        typeof(AbpWebMvcModule),
        typeof(AbpZeroOwinModule),
        typeof(AbpProjectTemplateDataModule),
           typeof(AbpProjectTemplateWebAppApiModule),

        typeof(AbpProjectTemplateApplicationModule)

    )]
    public class AbpProjectTemplateWebAppModule : AbpModule
    {
        public override void PreInitialize()
        {
           
        }
        public override void Initialize()
        {
            //进行以来注入
            IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());

            IocManager.IocContainer.Register(
                Component
                    .For<IAuthenticationManager>()
                    .UsingFactoryMethod(() => HttpContext.Current.GetOwinContext().Authentication)
                    .LifestyleTransient()
            );
            //Areas
            AreaRegistration.RegisterAllAreas();

            //Routes
            RouteConfig.RegisterRoutes(RouteTable.Routes);

            //Bundling
            BundleTable.Bundles.IgnoreList.Clear();
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }
 
    }

对Global.asax文件进行修改，修改后：

    public class WebApiApplication : AbpWebApplication<AbpProjectTemplateWebAppModule>
    {
        protected override void Application_Start(object sender, EventArgs e)
        {
            //Use UTC clock. Remove this to use local time for your application.
             
            //Log4Net configuration
            AbpBootstrapper.IocManager.IocContainer
                .AddFacility<LoggingFacility>(f => f.UseAbpLog4Net()
                    .WithConfig("log4net.config")
                );

            base.Application_Start(sender, e);
        }

       
    }

不要尝试在webapp中，直接引入abp.webapi。我失败了两次，但是之前的0.97版本又是可以的。。

然后创建一个webappapi的类库：
引入如下的nuge包
这个是webAppApi项目中的package.config:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Abp" version="1.5.1" targetFramework="net452" />
  <package id="Abp.AutoMapper" version="1.5.1" targetFramework="net452" />
  <package id="Abp.Web" version="1.5.1" targetFramework="net452" />
  <package id="Abp.Web.Api" version="1.5.1" targetFramework="net452" />
  <package id="Abp.Web.Common" version="1.5.1" targetFramework="net452" />
  <package id="Abp.Zero" version="1.5.1" targetFramework="net452" />
  <package id="Abp.Zero.Owin" version="1.5.1" targetFramework="net452" />
  <package id="AutoMapper" version="5.2.0" targetFramework="net452" />
  <package id="Castle.Core" version="3.3.3" targetFramework="net461" />
  <package id="Castle.LoggingFacility" version="3.4.0" targetFramework="net452" />
  <package id="Castle.Windsor" version="3.4.0" targetFramework="net452" />
  <package id="JetBrains.Annotations" version="10.4.0" targetFramework="net452" />
  <package id="Microsoft.AspNet.Identity.Core" version="2.2.1" targetFramework="net452" />
  <package id="Microsoft.AspNet.Identity.Owin" version="2.2.1" targetFramework="net452" />
  <package id="Microsoft.AspNet.WebApi" version="5.2.3" targetFramework="net452" />
  <package id="Microsoft.AspNet.WebApi.Client" version="5.2.3" targetFramework="net452" />
  <package id="Microsoft.AspNet.WebApi.Core" version="5.2.3" targetFramework="net452" />
  <package id="Microsoft.AspNet.WebApi.Owin" version="5.2.3" targetFramework="net452" />
  <package id="Microsoft.AspNet.WebApi.WebHost" version="5.2.3" targetFramework="net452" />
  <package id="Microsoft.Bcl" version="1.1.10" targetFramework="net452" />
  <package id="Microsoft.Bcl.Async" version="1.0.168" targetFramework="net452" />
  <package id="Microsoft.Bcl.Build" version="1.0.21" targetFramework="net452" />
  <package id="Microsoft.Owin" version="3.1.0" targetFramework="net461" />
  <package id="Microsoft.Owin.Security" version="3.1.0" targetFramework="net461" />
  <package id="Microsoft.Owin.Security.Cookies" version="3.0.1" targetFramework="net461" />
  <package id="Microsoft.Owin.Security.OAuth" version="3.0.1" targetFramework="net461" />
  <package id="Newtonsoft.Json" version="9.0.1" targetFramework="net452" />
  <package id="Nito.AsyncEx" version="4.0.1" targetFramework="net452" />
  <package id="Owin" version="1.0" targetFramework="net452" />
  <package id="Swashbuckle.Core" version="5.5.3" targetFramework="net452" />
  <package id="System.Collections.Immutable" version="1.3.1" targetFramework="net452" />
  <package id="System.Linq.Dynamic" version="1.0.7" targetFramework="net452" />
</packages>

然后下面就是创建一个"AbpProjectTemplateWebAppApiModule.cs"

 /// <summary>
    /// 在系统中进行WebApi的配置
    /// </summary>
    [DependsOn(typeof(AbpWebApiModule), typeof(AbpProjectTemplateApplicationModule))]
    public class AbpProjectTemplateWebAppApiModule : AbpModule
    {
       
        public override void Initialize()
        {
            IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());           
            Configuration.Modules.AbpWebApi().DynamicApiControllerBuilder
                .ForAll<IApplicationService>(typeof(AbpProjectTemplateApplicationModule).Assembly, "app")
                .Build();
            Configuration.Modules.AbpWebApi().HttpConfiguration.Filters.Add(new HostAuthenticationFilter("Bearer"));      
        }        
    }

然后就是配置EnableSwaggerUi了。这里的教程，请去看：ABP教程-给项目添加SwaggerUI,生成动态webapi

跑起来了后的截图：

API截图

接口太多了。那么我们就来折腾下
首先在application层创建一个

  /// <summary>
    /// 使用该特性进行app过滤
    ///  
    /// </summary>
    public class WebAppApiAttribute:System.Attribute
    {
        
    }

对AbpProjectTemplateWebAppApiModule中的配置方法进行改造下

Configuration.Modules.AbpWebApi().DynamicApiControllerBuilder
    .ForAll<IApplicationService>(Assembly.GetExecutingAssembly(), "app")
    .ForMethods(builder =>
    {
           if (!a.Method.IsDefined(typeof(WebAppApiAttribute)))
                        {
                            a.DontCreate = true;
                        }
    })
    .Build();

然后在特定的方法上打上标记。

 public interface ICachingAppService : IApplicationService
    {
        [WebAppApi]
        ListResultDto<CacheDto> GetAllCaches();

        Task ClearCache(EntityDto<string> input);
        [WebAppApi]
        Task ClearAllCaches();
    }

然后我们运行项目，看到如下结果：
