MinimalAPI---使用扩展类实现分类管理

1.Restful风格

Program.cs的代码

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
WebApplication app = builder.Build();
app.UseSwagger();
app.UseSwaggerUI();

app.MapGet("GetRequest",()=>"This is a Get Request");
app.MapPost("PostRequest", () => "This is a Post Request");
app.MapPut("PutRequest", () => "This is a Put Request");
app.MapDelete("DeleteRequest", () => "This is a Delete Request");
app.MapMethods("AllRequest",new string[] { "GET","POST","PUT","DELETE","OPTIONS","HEAD"},()=> "This is a ALL Request");

app.Run();

2.分类来写API

如果api过多，全部写在program.cs中显得过于复杂，这时可以使用扩展类实现分类写API

（1）项目结构

 

 （2）PhoneApiExtensions.cs

namespace Advanced.NET6.WebApi
{
    public static class PhoneApiExtensions
    {
        public static void PhoneApi(this WebApplication app)
        {
            app.MapGet("/GetOPPO", () =>
            {
                return new
                {
                    Port = app.Configuration["Port"],
                    Name = "OPPO手机",
                    Remark = $"数据来自于：{app.Configuration["Port"]}的服务器"
                };
            }).WithTags("Phone");

            app.MapPost("/AddOPPO", () =>
            {
                return new
                {
                    Result = true,
                    Message = "操作成功"
                };
            }).WithTags("Phone");

            app.MapPut("/AddOPPONew", () =>
            {
                return new
                {
                    Result = true,
                    Message = "操作成功"
                };
            }).WithTags("Phone");

            app.MapDelete("/DelOPPO", () =>
            {
                return new
                {
                    Result = true,
                    Message = "操作成功"
                };
            }).WithTags("Phone");
        }
    }
}

（3）ProductApiExtensions.cs

namespace Advanced.NET6.WebApi
{
    public static class ProductApiExtensions
    {
        public static void ProductApi(this WebApplication app)
        {
            app.MapGet("/GetIPhone13", () =>
            {
                return new
                {
                    Id = 123,
                    Name = "IPhone13"
                };
            }).WithTags("Product");

            app.MapGet("/test/GetHuaWeiP40", () =>
            {
                return new
                {
                    Port = app.Configuration["Port"],
                    Name = "华为P40",
                    Remark = $"当前这条信息来自于：{app.Configuration["Port"]}的服务器",
                    Date = DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss")
                };
            }).WithTags("Product");
        }
    }
}

（4）Program.cs

using Advanced.NET6.WebApi;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

app.UseSwagger();
app.UseSwaggerUI();



#region 自定义的api
//如果api一旦过多，api过于复杂
//解决方案：
//1.还是使用带有控制器的weapi
//2.如果使用MinimalApi--分类来写API --扩展类的方式
app.ProductApi();
app.PhoneApi();

#endregion

app.Run();

（5）Swagger显示
