廢話不多說直接來看

第一步：安裝nuget包：Swashbuckle.AspNetCore.Swagger

安裝好後就可以看到啦

第二步：找到Startup開始在^{ConfigureServices} 配置

1  public void ConfigureServices(IServiceCollection services)
2         {
3             services.AddControllers();
4          //swagger註冊
5             services.AddSwaggerGen(m => {
6                 m.SwaggerDoc("
 
v1",new Microsoft.OpenApi.Models.OpenApiInfo { Title="code_first",Version="v1"});
7             }); 
8        }

第三步：繼續在Startup的Configure配置

 1  public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
 2         {
 3             if (env.IsDevelopment())
 4             {
 5
 
                 app.UseDeveloperExceptionPage();
 6             }
 7 
 8             app.UseRouting();
 9             //swagger
10             app.UseSwagger();
11            app.UseSwaggerUI(s => {
12                 s.SwaggerEndpoint("/swagger/v1/swagger.json","v1");
13             });
14             app.UseAuthorization();
 
15 
16             app.UseEndpoints(endpoints =>
17             {
18                 endpoints.MapControllers();
19             });
20  
21          
22          }
