为什么要使用Api分组

1. 同一个项目各端接口分离
2. 前端更好的查询各端Api接口
3. 后端更好的管理接口分组

本文使用的是.Net6项目

SwaggerApiInfo.cs

using Microsoft.OpenApi.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Lotus.Blog.TNT.Swagger
{
    internal class SwaggerApiInfo
    {
        /// <summary>
        /// URL前缀
        /// </summary>
        public string UrlPrefix { get; set; }

        /// <summary>
        /// 名称
        /// </summary>
        public string Name { get; set; }

        /// <summary>
        /// <see cref="Microsoft.OpenApi.Models.OpenApiInfo"/>
        /// </summary>
        public OpenApiInfo OpenApiInfo { get; set; }
    }
}

如何使用

[ApiExplorerSettings(GroupName = SwaggerExtensions.Grouping.GroupName_v2)]

Program.cs使用

注意! 如果不是.Net项目 需要在startup.cs 文件中注册

实现效果

这样就达到了Swagger分组，将各个端接口分离开来，方便前端开发工程师查询

Swagger Controller 注释

在SwaggerExtensions.cs 文件中修改代码

            var xmlFiles = System.IO.Directory.GetFiles(AppContext.BaseDirectory, "*.XML");
                foreach (var file in xmlFiles)
                {
                    if (file.Contains("Lotus.Blog.Api.xml"))
                    {
                        options.IncludeXmlComments(file,true);
                    }
                    else
                    {
                        options.IncludeXmlComments(file, true);
                    }

                }
               

Logtus.Blog.Api.xml 为你Controller项目的名称

Controller增加注释

实现效果
