.NET Core 3.0 WebApi 使用Swagger

1、安装指定版本： Swashbuckle.AspNetCore 5.0.0-rc4（目前稳定版本4.0.1在AspNetCore3.0中会报错误）

2、后台C#代码要严格格式必须加[HttpPost]或者[HttpGet]

3、Startup类中配置如下代码

     

     public void ConfigureServices(IServiceCollection services)

      {

            services.AddControllers();

            services.AddRazorPages();

            #region Swagger配置

            services.AddSwaggerGen(c =>

            {

                c.SwaggerDoc("v1", new Microsoft.OpenApi.Models.OpenApiInfo { Title = "My API", Version = "v1" }); c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First()); }); 

           #endregion 
           services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Latest); 
      }

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}

app.UseRouting();
app.UseStaticFiles();//启动静态文件
app.UseAuthorization();

#region session配置
app.UseSession();
#endregion

#region Swagger配置
//启用中间件服务生成Swagger作为JSON终结点
app.UseSwagger();
//启用中间件服务对swagger-ui，指定Swagger JSON终结点
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
});
#endregion

app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
endpoints.MapAreaControllerRoute(
name: "areas", "Admin",
pattern: "{area:exists}/{controller=Users}/{action=Index}/{id?}");
endpoints.MapRazorPages();
});

}

4、地址栏输入地址（注意端口每个人的机器上的端口不一样）：http://localhost:56534/swagger/v1/swagger.json

5、地址栏输入地址：http://localhost:56534/swagger/index.html
