ASP.NET Core 3.1使用Swagger

1、添加Swagger

直接在NuGet里面搜索Swashbuckle.AspNetCore包进行安装：

2、添加服务

在Startup类的ConfigureServices方法里面注入服务：  验证授权和 注释信息

 public void ConfigureServices(IServiceCollection services)
        {
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new OpenApiInfo { Title = "sukcore后台Api", Version = "v1" });
                var security = new Dictionary<string, IEnumerable<string>>
                { { "sukcore", new string[] { } }};
                c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme()
                {
                    Description = "JWT授权token前面需要加上字段Bearer与一个空格,如Bearer token",
                    Name = "Authorization",
                    In = ParameterLocation.Header,
                    Type = SecuritySchemeType.ApiKey,
                    BearerFormat = "JWT",
                    Scheme = "Bearer"
                });

                c.AddSecurityRequirement(new OpenApiSecurityRequirement
                {
                    {
                        new OpenApiSecurityScheme
                        {
                            Reference = new OpenApiReference {
                                Type = ReferenceType.SecurityScheme,
                                Id = "Bearer"
                            }
                        },
                        new string[] { }
                    }
                });

                // 获取xml文件名
                var xmlFile = $"{System.Reflection.Assembly.GetExecutingAssembly().GetName().Name}.xml";
                // 获取xml文件路径
                var xmlPath = System.IO.Path.Combine(AppContext.BaseDirectory, xmlFile);
                // 添加控制器层注释，true表示显示控制器注释
                c.IncludeXmlComments(xmlPath, true);
            });

        }

3、添加中间件

在Startup类的Configure方法里面添加Swagger有关的中间件：

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // 添加Swagger有关中间件
    app.UseSwagger();
    app.UseSwaggerUI(c =>
    {
        c.SwaggerEndpoint("/swagger/v1/swagger.json", "API Demo v1");
    });
}

4、让Swagger能够显示实体模型的注释

如果你的实体不在asp.net core项目内需要把所使用实体的项目也设置xml文档生成，并在swagger中设置，xml文档为多个；
