# Demo

# 📚 快速开始

# 🚀安装包

以下为使用Swashbuckle.AspNetCore.Swagger底层组件

1.Install the standard Nuget package into your ASP.NET Core application.

Package Manager : 

Install-Package Swashbuckle.AspNetCore.Swagger
Install-Package Swashbuckle.AspNetCore.SwaggerGen
Install-Package IGeekFan.AspNetCore.Knife4jUI

OR

CLI :

dotnet add package Swashbuckle.AspNetCore.Swagger
dotnet add package Swashbuckle.AspNetCore.SwaggerGen
dotnet add package IGeekFan.AspNetCore.Knife4jUI

2.In the ConfigureServices method of Startup.cs, register the Swagger generator, defining one or more Swagger documents.

using Microsoft.AspNetCore.Mvc.Controllers
using Microsoft.OpenApi.Models;
using Swashbuckle.AspNetCore.SwaggerGen;
using IGeekFan.AspNetCore.Knife4jUI;

# 🚁 ConfigureServices

3.服务配置，CustomOperationIds和AddServer是必须的。

   services.AddSwaggerGen(c =>
    {
        c.SwaggerDoc("v1",new OpenApiInfo{Title = "API V1",Version = "v1"});
        c.AddServer(new OpenApiServer()
        {
            Url = "",
            Description = "vvv"
        });
        c.CustomOperationIds(apiDesc =>
        {
            var controllerAction = apiDesc.ActionDescriptor as ControllerActionDescriptor;
            return  controllerAction.ControllerName+"-"+controllerAction.ActionName;
        });
    });

# 💪 Configure

中间件配置

app.UseSwagger();

app.UseKnife4UI(c =>
{
    c.RoutePrefix = ""; // serve the UI at root
    c.SwaggerEndpoint("/v1/api-docs", "V1 Docs");
});

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllers();
    endpoints.MapSwagger("{documentName}/api-docs");
});

5.更多功能

为文档添加注释在项目上右键--属性--生成

在AddSwaggerGen方法中添加如下代码

c.IncludeXmlComments(Path.Combine(AppContext.BaseDirectory, "SwaggerDemo.xml"),true);

最后一个参数设置为true，代表启用控制器上的注释

运行后如看不到控制器上注释显示，请点开文档管理->个性化设置，开启分组tag显示description说明属性

# NSwag.AspNetCore

（请参考目录test/WebSites/NSwag.Swagger.Knife4jUI）

public void ConfigureServices(IServiceCollection services)
 {
    // 其它Service
     services.AddOpenApiDocument();
 }

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
            // 其它 Use
          app.UseOpenApi();
          app.UseKnife4UI(c =>
         {
               c.RoutePrefix = "";
               c.SwaggerEndpoint("/swagger/v1/swagger.json");
          });
}

即可使用 Knife4jUI
