小编点评

**Biwen.QuickApi项目介绍** **简介** Biwen.QuickApi是一个简单易用的Minimal Web API交互模块，它遵循了 REPR 设计理念，提供最简单的使用体验。 **使用方式** 1. **NuGet 安装**：`dotnet add package Biwen.QuickApi` 2. **使用 BiwenQuickApisBuilder.Services.AddBiwenQuickApis** 方法添加 QuickApi 3. **定义请求和响应**：定义 `HelloApiRequest` 和 `HelloApiResponse` 类，继承 `BaseRequest` 和 `BaseResponse` 4. **定义 QuickApi**：定义 `HelloApi` 类，继承 `BaseQuickApi`，其中包含以下方法： - `Execute`：处理请求并返回响应 - `HandlerBuilder`：构建路由器 **示例** ```csharp // HelloApiRequest public class HelloApiRequest : BaseRequest & HelloApiRequest { public string? Name { get; set; } public HelloApiRequest() { RuleFor(x => x.Name).NotNull().Length(5, 10); } } // HelloApiResponse public class HelloApiResponse : BaseResponse { public string Message { get; set; } } ``` **配置** 可以使用 `app.MapGet("/from-quickapi", async (IBusiness business) => {...})` 方法映射 QuickApi 到一个 `IBusiness` 接口。 **其他** - 支持多个参数的绑定，但通过使用复杂化的 `Request` 对象。 - 支持全局中间件和拦截器，重写 `HandlerBuilder` 方法。

使用方式

Step0 Nuget Install

dotnet add package Biwen.QuickApi

Step1 UseBiwenQuickApis

builder.Services.AddBiwenQuickApis(o =>
{
    o.RoutePrefix = "quick";
    //不需要驼峰模式设置为null
    //o.JsonSerializerOptions.PropertyNamingPolicy = null;
});

//....
app.MapBiwenQuickApis();

Step2 Define Request and Response

    public class HelloApiRequest : BaseRequest<HelloApiRequest>
    {
        public string? Name { get; set; }

        /// <summary>
        /// 别名绑定字段
        /// </summary>
        [AliasAs("a")]
        public string? Alias { get; set; }

        public HelloApiRequest()
        {
            RuleFor(x => x.Name).NotNull().Length(5, 10);
        }
    }

    /// <summary>
    /// 模拟自定义绑定的Request
    /// </summary>
    public class CustomApiRequest : BaseRequest<CustomApiRequest>
    {
        public string? Name { get; set; }

        public CustomApiRequest()
        {
            RuleFor(x => x.Name).NotNull().Length(5, 10);
        }
    }

    /// <summary>
    /// 自定义的绑定器
    /// </summary>
    public class CustomApiRequestBinder : IReqBinder<CustomApiRequest>
    {
        public async Task<CustomApiRequest> BindAsync(HttpContext context)
        {
            var request = new CustomApiRequest
            {
                Name = context.Request.Query["c"]
            };
            await Task.CompletedTask;
            return request;
        }
    }

    public class HelloApiResponse : BaseResponse
    {
        public string? Message { get; set; }
    }

Step3 Define QuickApi

    /// <summary>
    /// get ~/admin/index
    /// </summary>
    [QuickApi("index", Group = "admin", Verbs = Verb.GET | Verb.POST, Policy = "admin")]
    public class NeedAuthApi : BaseQuickApi
    {
        public override EmptyResponse Execute(EmptyRequest request)
        {
            return EmptyResponse.Instance;
        }
    }

    /// <summary>
    /// get ~/hello/world/{name}
    /// </summary>
    [QuickApi("world/{name}", Group = "hello", Verbs = Verb.GET | Verb.POST)]
    public class HelloApi : BaseQuickApi<HelloApiRequest, HelloApiResponse>
    {
        private readonly HelloService _service;
        private readonly IHttpContextAccessor _httpContextAccessor;

        public Hello4Api(HelloService service,IHttpContextAccessor httpContextAccessor)
        {
            _service = service;
            _httpContextAccessor = httpContextAccessor;
        }

        public override HelloApiResponse Execute(HelloApiRequest request)
        {
            var hello = _service.Hello($"hello world {_httpContextAccessor.HttpContext!.Request.Path} !");
            return new HelloApiResponse
            {
                Message = hello
            };
        }
    }

    /// <summary>
    /// get ~/custom?c=11112222
    /// </summary>
    [QuickApi("custom", Verbs = Verb.GET)]
    public class CustomApi : BaseQuickApi<CustomApiRequest>
    {
        public CustomApi()
        {
            UseReqBinder<CustomApiRequestBinder>();
        }

        public override async Task<EmptyResponse> ExecuteAsync(CustomApiRequest request)
        {
            await Task.CompletedTask;
            Console.WriteLine($"获取自定义的 CustomApi:,从querystring:c绑定,{request.Name}");
            return EmptyResponse.New;
        }

        /// <summary>
        /// 提供minimal扩展
        /// </summary>
        /// <param name="builder"></param>
        /// <returns></returns>
        public override RouteHandlerBuilder HandlerBuilder(RouteHandlerBuilder builder)
        {
            //自定义描述
            builder.WithOpenApi(operation => new(operation)
            {
                Summary = "This is a summary",
                Description = "This is a description"
            });

            //自定义标签
            builder.WithTags("custom");

            //自定义过滤器
            builder.AddEndpointFilter(async (context, next) =>
            {
                Console.WriteLine("自定义过滤器!");
                return await next(context);
            });

            //自定义Api版本
            //默认为版本1.0,如果需要访问其他版本,需要在querystring中添加?api-version=2.0 :)
            builder.HasApiVersion(1.0).WithGroupName("1.0");
            builder.HasApiVersion(2.0).WithGroupName("2.0");

            return builder;
        }

    }

Step4 Enjoy !

//直接访问
// GET ~/hello/world/biwen
// GET ~/hello/world/biwen?name=biwen
// POST ~/hello/world/biwen
// GET ~/custom?c=11112222

//你也可以把QuickApi当Service使用
app.MapGet("/fromapi", async (Biwen.QuickApi.DemoWeb.Apis.Hello4Api api) =>
{
    //通过你的方式获取请求对象
    var req = new EmptyRequest();
    //验证请求对象
    var result = req.RealValidator.Validate(req);
    if (!result.IsValid)
    {
        return Results.BadRequest(result.ToDictionary());
    }
    //执行请求
    var x = await api.ExecuteAsync(new EmptyRequest());
    return Results.Ok(x);
});

Step5 OpenApi 以及Client代理

• 你可以全局配置版本号,以及自定义的OpenApi描述
• 你可以重写QuickApi的HandlerBuilder方法,以便于你自定义的OpenApi描述
• 我们强烈建议您使用Refit风格直接撸接口,以便于您的客户端和服务端保持一致的接口定义
• 因为遵循REPR风格,所以不推荐SwaggerUI或使用SwaggerStudio生成代理代码,除非您的QuickApi定义的相当规范(如存在自定义绑定,别名绑定等)!

/// <summary>
/// refit client
/// </summary>
public interface IBusiness
{
    [Refit.Get("/fromapi")]
    public Task<TestRsp> TestPost();
}

//Refit
builder.Services.AddRefitClient<IBusiness>()
    .ConfigureHttpClient(c => c.BaseAddress = new Uri("http://localhost:5101"));

var app = builder.Build();

app.MapGet("/from-quickapi", async (IBusiness bussiness) =>
{
    var resp = await bussiness.TestPost();
    return Results.Content(resp.Message);
});

Q&A

• 为什么不支持多个参数的绑定?
  -- 因为我认为这样的Api设计是不合理的,我们遵循REPR设计理念,如果你需要多个参数,请使用复杂化的Request对象

• QuickApi中如何拿到HttpContext对象?
  -- 请在构造函数中注入IHttpContextAccessor获取

• 是否支持Minimal的中间件和拦截器?
  -- 支持的,本身QuickApi就是扩展了MinimalApi,底层也是Minimal的处理机制,所以请考虑全局的中间件和拦截器,以及重写QuickApi的HandlerBuilder方法
