[ABP框架]动态web Api的拦截用法。

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。

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

<?xml version="1.0" encoding="utf-8"?>

</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：

[ABP框架]动态web Api的拦截用法。-LMLPHP

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：
