Panda.DynamicWebApi

Panda.DynamicWebApi 是一个动态生成WebApi的组件,生成的API符合Restful风格,受启发于ABP。它可以根据符合条件的类来生成WebApi,由MVC框架直接调用逻辑,无性能问题,完美兼容Swagger来构建API说明文档,与手动编写Controller相比并无区别。

应用场景:DDD架构中的应用逻辑层,可使用本组件来直接生成WebApi,而无需再用Controller来调用。

Latest version

1.快速入门

(1)新建一个 ASP.NET Core WebApi(或MVC) 项目

(2)通过Nuget安装组件

Install-Package Panda.DynamicWebApi

(3)创建一个类命名为 AppleAppService,实现 IDynamicWebApi 接口,并加入特性 [DynamicWebApi]

[DynamicWebApi]
public class AppleAppService: IDynamicWebApi
{
    private static readonly Dictionary<int,string> Apples=new Dictionary<int, string>()
    {
        [1]="Big Apple",
        [2]="Small Apple"
    };

    /// <summary>
    /// Get An Apple.
    /// </summary>
    /// <param name="id"></param>
    /// <returns></returns>
    [HttpGet("{id:int}")]
    public string Get(int id)
    {
        if (Apples.ContainsKey(id))
        {
            return Apples[id];
        }
        else
        {
            return "No Apple!";
        }
    }

    /// <summary>
    /// Get All Apple.
    /// </summary>
    /// <returns></returns>
    public IEnumerable<string> Get()
    {
        return Apples.Values;
    }

    public void Update(UpdateAppleDto dto)
    {
        if (Apples.ContainsKey(dto.Id))
        {
            Apples[dto.Id] =dto.Name;
        }
    }

    /// <summary>
    /// Delete Apple
    /// </summary>
    /// <param name="id">Apple Id</param>
    [HttpDelete("{id:int}")]
    public void Delete(int id)
    {
        if (Apples.ContainsKey(id))
        {
            Apples.Remove(id);
        }
    }

}

(4)在 Startup 中注册 DynamicWebApi

public void ConfigureServices(IServiceCollection services)
{
    // 默认配置
    services.AddDynamicWebApi();

    // 自定义配置
    services.AddDynamicWebApi((options) =>
    {
        // 指定全局默认的 api 前缀
        options.DefaultApiPrefix = "apis";
    
        /**
         * 清空API结尾,不删除API结尾;
         * 若不清空 CreatUserAsync 将变为 CreateUser
         */
        options.RemoveActionPostfixes.Clear();
    
        /**
         * 自定义 ActionName 处理函数;
         */
        options.GetRestFulActionName = (actionName) => actionName;
    
        /**
         * 指定程序集 配置 url 前缀为 apis
         * 如: http://localhost:8080/apis/User/CreateUser
         */
        options.AddAssemblyOptions(this.GetType().Assembly, apiPreFix: "apis");
    
        /**
         * 指定程序集 配置所有的api请求方式都为 POST
         */
        options.AddAssemblyOptions(this.GetType().Assembly, httpVerb: "POST");
    
        /**
         * 指定程序集 配置 url 前缀为 apis, 且所有请求方式都为POST
         * 如: http://localhost:8080/apis/User/CreateUser
         */
        options.AddAssemblyOptions(this.GetType().Assembly, apiPreFix: "apis", httpVerb: "POST");
    });
}

(5)添加 Swagger

(6)运行

运行浏览器以后访问 <你的项目地址>/swagger/index.html,将会看到为我们 AppleAppService 生成的 WebApi

本快速入门 Demo 地址:点我

2.更进一步

(1)要让类生成动态API需要满足两个条件,一个是该类直接间接实现 IDynamicWebApi,同时该类本身或者父抽象类或者实现的接口具有特性 DynamicWebApi

(2)添加特性 [NonDynamicWebApi] 可使一个类或者一个方法不生成API,[NonDynamicWebApi] 具有最高的优先级。

(3)会对符合规则的动态API类名进行后缀的删除,如:我们快速入门的 AppleAppService,会被删除 AppService 后缀,这个规则是可以动态配置的。

(4)会自动添加API路由前缀,默认会为所有API添加 api前缀

(5)默认的HTTP动词为POST,可以理解为API的 Http Method。但可以通过 HttpGet/HttpPost/HttpDelete 等等ASP.NET Core 内置特性来覆盖

(6)可以通过HttpGet/HttpPost/HttpDelete 等内置特性来覆盖默认路由

(7)默认会根据你的方法名字来设置HTTP动词,如 CreateApple 或者 Create 生成的API动词为 POST,对照表如下,若命中(忽略大小写)对照表那么该API的名称中的这部分将会被省略,如 CreateApple 将会变成 Apple,如未在以下对照表中,将会使用默认动词 POST

方法名开头 动词
create POST
add POST
post POST
get GET
find GET
fetch GET
query GET
update PUT
put PUT
delete DELETE
remove DELETE

(8)强烈建议方法名称使用帕斯卡命名(PascalCase)规范,且使用以上对照表的动词。如:

添加苹果 → Add/AddApple/Create/CreateApple

更新苹果 → Update/UpdateApple

...

(9)[DynamicWebApi] 特性因为可被继承,所以为了父类被误识别,禁止放在除抽象类、接口以外的父类上。 (10)自定义 WebApi注册

1.基础功能

public void ConfigureServices(IServiceCollection services)
{
    // 自定义配置
    services.AddDynamicWebApi((options) =>
    {
        //自定义注册的WebApi
        options.SelectController = new ServiceLocalSelectController();
        //自定义WebApi路由地址
        options.ActionRouteFactory = new ServiceActionRouteFactory();
    });
}

根据 ServiceAttribute 注册WebApi和分配路由地址

[AttributeUsage(AttributeTargets.Class)]
public class ServiceAttribute : Attribute
{
    public ServiceAttribute()
    {
        ServiceName = string.Empty;
    }

    public ServiceAttribute(string serviceName)
    {
        ServiceName = serviceName;
    }

    public string ServiceName { get; }
}

实现 ISelectController 接口,通过查找类是否有ServiceAttribute特性为注册WebApi条件

internal class ServiceLocalSelectController : ISelectController
{
    public bool IsController(Type type)
    {
        return type.IsPublic && type.GetCustomAttribute<ServiceAttribute>() != null;
    }
}

实现 IActionRouteFactory 接口,生成路由规则 /api/ServiceName/Method

internal class ServiceActionRouteFactory : IActionRouteFactory
{
    public string CreateActionRouteModel(string areaName, string controllerName, ActionModel action)
    {
        var controllerType = action.ActionMethod.DeclaringType;
        var serviceAttribute = controllerType.GetCustomAttribute<ServiceAttribute>();

        var _controllerName = serviceAttribute.ServiceName == string.Empty ? controllerName.Replace("Service", "") : serviceAttribute.ServiceName.Replace("Service", "");

        return $"api/{_controllerName}/{action.ActionName.Replace("Async", "")}";
    }
}

ServiceAttribute.ServiceName为空时,controllerName 替换 "Service" 字符串为空,反之则 ServiceAttribute.ServiceName 替换 "Service" 字符串为空。 Method 名替换 "Async" 字符串为空。

2.外部动态 WebApi

创建一个 Other.Controller 实现 一个外部 Service

[Service("Other.Server")]
public class OtherService
{
    public int Show()
    {
        return 100;
    }

    public Task<int> TaskIntAsync()
    {
        return Task.FromResult(100);
    }
}
public void ConfigureServices(IServiceCollection services)
{
    // 自定义配置
    services.AddDynamicWebApiCore<ServiceLocalSelectController, ServiceActionRouteFactory>();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseDynamicWebApi((serviceProvider,options) =>
    {
        options.AddAssemblyOptions(typeof(OtherService).Assembly);
    });
}

3.配置

所有的配置均在对象 DynamicWebApiOptions 中,说明如下:

属性名 是否必须 说明
DefaultHttpVerb 默认值:POST。默认HTTP动词
DefaultAreaName 默认值:空。Area 路由名称
DefaultApiPrefix 默认值:api。API路由前缀
RemoveControllerPostfixes 默认值:AppService/ApplicationService。类名需要移除的后缀
RemoveActionPostfixes 默认值:Async。方法名需要移除的后缀
FormBodyBindingIgnoredTypes 默认值:IFormFile。不通过MVC绑定到参数列表的类型。
