在ASP.NET Core 2.2中，您可以使用Swagger来定义特定的安全定义。下面是一个示例解决方法，其中包含了相关代码示例：

步骤1：安装Swagger和相关包 在您的项目中，打开NuGet包管理器控制台，并运行以下命令安装Swagger和相关包：

Install-Package Swashbuckle.AspNetCore -Version 4.0.1
Install-Package Swashbuckle.AspNetCore.Annotations -Version 4.0.1

步骤2：在Startup.cs文件中配置Swagger 在ConfigureServices方法中，添加以下代码来配置Swagger和定义安全定义：

using Microsoft.OpenApi.Models;

public void ConfigureServices(IServiceCollection services)
{
    // ...

    services.AddSwaggerGen(c =>
    {
        c.SwaggerDoc("v1", new OpenApiInfo { Title = "Your API", Version = "v1" });
        
        // 定义安全定义
        c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
        {
            Description = "JWT Authorization header using the Bearer scheme",
            Type = SecuritySchemeType.Http,
            Scheme = "bearer"
        });
        
        // 添加必要的安全要求
        c.AddSecurityRequirement(new OpenApiSecurityRequirement
        {
            {
                new OpenApiSecurityScheme
                {
                    Reference = new OpenApiReference
                    {
                        Type = ReferenceType.SecurityScheme,
                        Id = "Bearer"
                    }
                },
                new string[] {}
            }
        });
        
        // 添加注释以显示在Swagger UI中
        c.EnableAnnotations();
    });

    // ...
}

步骤3：在Startup.cs文件的Configure方法中启用Swagger中间件：

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    // ...

    app.UseSwagger();
    app.UseSwaggerUI(c =>
    {
        c.SwaggerEndpoint("/swagger/v1/swagger.json", "Your API V1");
    });

    // ...
}

步骤4：在您的Controller类或方法上使用Swagger注释 在您的Controller类或方法上添加Swagger注释，以定义安全要求：

using Microsoft.AspNetCore.Authorization;
using Swashbuckle.AspNetCore.Annotations;

[Authorize] // 添加身份验证特性
[SwaggerOperation(Summary = "Your summary", Description = "Your description", Tags = new[] { "Your tag" })]
[SwaggerResponse(200, "Success")]
[SwaggerResponse(401, "Unauthorized")]
[SwaggerResponse(500, "Internal server error")]
public class YourController : ControllerBase
{
    [HttpGet]
    [SwaggerOperation(OperationId = "YourOperation", Summary = "Your summary", Description = "Your description")]
    [SwaggerResponse(200, "Success")]
    [SwaggerResponse(401, "Unauthorized")]
    [SwaggerResponse(500, "Internal server error")]
    public ActionResult> Get()
    {
        // ...
    }

    // ...
}

希望这个解决方法对您有所帮助！
