Cyclops.FrameWork

Cyclops.FrameWork 基于aspnetcore封装的api框架，集成了一线开发的常用设置和基础功能；可以用较少的时间代价，让开发人员将精力更多地集中在业务上。

• [√] 全局api调用和框架级异常日志，支持Knife4j接口文档的查看、调试和代码生成
• [√] 接口入参校验，Cyclops.FrameWork中的接口参数校验完全基于System.ComponentModel.DataAnnotations，且在此基础上提供了验证数据是否存在ExistAttribute等扩展功能
• [√] 统一返回值，无论是使用Cyclops.FrameWork中的Result及其子类，或者CSharp中的裸类型都自动返回全局统一值，从框架上避免对接混乱
• [√] 标准化快捷文件上传、下载和excel的导入、导出，支持MS Azure和阿里OSS
• [√] 在安全方面集成jwt认证和SafeComparisonFilter防重放攻击，并且支持多租户权限
• [√] 标准化配置，支持Nacos

一、配置示例

{
  "HostingOptions": {
    "ServiceName": "Cyclops.WebApplication1",
    "AppOptions": {
      "Urls": [ "https://127.0.0.1:7000" ],
      "DisableSwagger": false,
      "HideConsoleLog": false,
      //jwt TokenManagement
      "JWTAuthConfig": {
        "Secret": "base64:HU8MlQQDHfGaQ+k+0q3z4HKJvNQUTjK5uRGodDATyKc=",
        "Issuer": "yswenli.cnblogs.com",
        "Audience": "Cyclops.FrameWork.WebApi",
        "AccessExpiration": 30
      },
      "MaxRequestSize": 5242880, //5242880,
      "UserStaticPath": true,
      "StaticPaths": [ "upload" ],
      "DisableSafeComparisonFilter": false,
      "SafeComparisonExpired": 5,
      "GloabVerifyCode": "9365"
    },
    "Domain": "https://dev.cyclops.com",
    "NacosConfig": {
      "Listeners": [
        {
          "Optional": false,
          "DataId": "Common",
          "Group": "DEFAULT_GROUP"
        },
        {
          "Optional": false,
          "DataId": "OperationService",
          "Group": "DEFAULT_GROUP"
        }
      ],
      "Namespace": "dev",
      "ServerAddresses": [ "http://127.0.0.1:8848" ],
      "UserName": "",
      "Password": "",
      "ConfigUseRpc": false,
      "NamingUseRpc": false
    }
  }
}

AppConfig节点以下的可以与nacos集成

二、初始化代码示例

public class Program
{
    public static void Main(string[] args)
    {
        WebApp.OnStarted += WebApp_OnStarted;
        WebApp.OnStopped += WebApp_OnStopped;
        WebApp.RunWebHost<Startup>(args);
    }


    static void WebApp_OnStarted()
    {
        Logger.Info($"{WebApp.ServiceName}应用已启动");
    }


    static void WebApp_OnStopped()
    {
        Logger.Info($"{WebApp.ServiceName}应用已停止");
    }
}

    /// <summary>
    /// Startup
    /// </summary>
    public class Startup : BaseStartup
    {
        /// <summary>
        /// Startup
        /// </summary>
        /// <param name="configuration"></param>
        public Startup(IConfiguration configuration) : base(configuration)
        {

        }
    }

三、控制器示例

继承基类即可

public class AuthController : BaseApiController

方法示例

    /// <summary>
    /// Login
    /// </summary>
    /// <param name="input"></param>
    /// <returns></returns>
    [AllowAnonymous, HttpPost, DisplayName("Login")]
    public async Task<Result> Login([Required(ErrorMessage = "请输入用户名或密码"), FromBody] UserLoginInput input)
    {
        var user = new SysUser();
        return SuccessResult(await CreateToken(user));
    }

    /// <summary>
    /// 获取验证码
    /// </summary>
    /// <returns></returns>
    [AllowAnonymous]
    [SuppressMonitor]
    [DisplayName("获取验证码"), HttpGet]
    public Result GetCaptcha()
    {
        ICaptcha captcha = ServiceProviderUtil.GetRequiredService<ICaptcha>();
        var codeId = YitIdHelper.NextId().ToString();
        var captchas = captcha.Generate(codeId, 180);
        return SuccessResult(new { Id = codeId, Img = captchas.Base64 });
    }

四、集成数据校验

/// <summary>
/// 登录信息
/// </summary>
public class UserLoginInput
{
    /// <summary>
    /// 请输入用户名
    /// </summary>
    [Required(ErrorMessage = "请输入用户名"), Exists("用户名不存在", TableName = "bus_user", ColumnName = "user_name")]
    public string UserName { get; set; }
    /// <summary>
    /// 请输入密码
    /// </summary>
    [Required(ErrorMessage = "请输入密码"), Custom<UserLoginInput>("密码不正确", "Valide")]
    public string Password { get; set; }

    /// <summary>
    /// 验证密码
    /// </summary>
    /// <param name="input"></param>
    /// <returns></returns>
    public bool Valide(object? input)
    {
        if (input == null) return false;
        if (input is string password && password == "123456")
        {
            return true;
        }
        return false;

    }
}

五、防重放攻击示例

    /// <summary>
    /// 接口安全参数校验测试
    /// </summary>
    [SafeComparisonFilter]
    public class SafeController : BaseApiController
    {
        /// <summary>
        /// Test
        /// </summary>
        /// <param name="testInfo"></param>
        /// <returns></returns>
        [HttpPost]
        public Result Test([FromBody] TestInfo testInfo)
        {
            return SuccessResult(testInfo);
        }

        /// <summary>
        /// test2
        /// </summary>
        /// <returns></returns>
        [HttpGet, AllowAnonymous, NoSafeComparisonFilter]
        public Result Test2()
        {
            return SuccessResult();
        }
    }

六、文件上传下载Excel导入导出示例

   public class FileAdminController : BaseApiController
   {
       /// <summary>
       /// 导入
       /// </summary>
       /// <returns></returns>
       [HttpPost]
       [NoLoginAuth, AllowAnonymous]
       public Result Import(IFormCollection collection)
       {
           var data = collection.SaveAsDataTable();
           return SuccessResult(data);
       }


       /// <summary>
       /// 导出
       /// </summary>
       /// <returns></returns>
       [HttpPost]
       [NoLoginAuth, AllowAnonymous]
       public IActionResult Export()
       {
           return _env.Download("export.png");
       }

       /// <summary>
       /// 导出数据文件
       /// </summary>
       /// <returns></returns>
       [HttpGet]
       [NoLoginAuth, AllowAnonymous]
       public IActionResult ExportFile([FromQuery] bool isExcel = false)
       {
           var fileName = "export.xlsx";
           if (!isExcel)
           {
               fileName = "export.csv";
           }
           var dt = new DataTable();
           //return _env.ExportFile(dt, fileName);
           return Export(dt, fileName);
       }


       /// <summary>
       /// 导出数据文件
       /// </summary>
       /// <returns></returns>
       [HttpGet]
       [NoLoginAuth, AllowAnonymous]
       public IActionResult ExportDataFile([FromQuery] bool isExcel = false)
       {
           var fileName = "export.xlsx";
           if (!isExcel)
           {
               fileName = "export.csv";
           }
           var list = new List<BusUser>
           {
               new BusUser()
               {
                   Id = 1,
                   UserName = "张三"
               }
           };
           //return _env.ExportFile(list, fileName);
           return Export(list, fileName);
       }



       /// <summary>
       /// 测试上传文件大小
       /// </summary>
       /// <returns></returns>
       [HttpPost]
       public async Task<IActionResult> UploadFile(IFormCollection form)
       {
           var fileStream = await form.SaveAsStreamsAsync();

           return fileStream.First().Value.Download("test.jpg");
       }

       /// <summary>
       /// 测试限制上传文件大小
       /// </summary>
       /// <param name="form"></param>
       /// <returns></returns>

       [HttpPost, RequestSizeLimit(2 * 1024 * 1024)]
       public async Task<IActionResult> UploadFileByLimit(IFormCollection form)
       {
           var fileStream = await form.SaveAsStreamsAsync();

           return fileStream.First().Value.Download("test.jpg");
       }

       /// <summary>
       /// 测试不限制上传文件大小
       /// </summary>
       /// <param name="form"></param>
       /// <returns></returns>

       [HttpPost, DisableRequestSizeLimit]
       public async Task<IActionResult> UploadFileByNonLimit(IFormCollection form)
       {
           var fileStream = await form.SaveAsStreamsAsync();

           return fileStream.First().Value.Download("test.jpg");
       }       

      /// <summary>
      /// 示例获取流
      /// </summary>
      /// <returns></returns>
      [HttpGet]
      public async Task<Stream> GetStream()
      {
          var ms = new MemoryStream(RandomUtil.GetBytes(1024));
          return await Task.FromResult(ms);
      }

      /// <summary>
      /// 示例获取字节数组
      /// </summary>
      /// <returns></returns>
      [HttpGet]
      public async Task<byte[]> GetBytes()
      {
          return await Task.FromResult(RandomUtil.GetBytes(1024));
      }
   }

七、支持非api接口内容

        /// <summary>
        /// 返回指定内容结果
        /// </summary>
        /// <param name="controller"></param>
        /// <param name="text"></param>
        /// <param name="contentType"></param>
        /// <param name="statusCode"></param>
        /// <returns></returns>
        public async Task<IActionResult> ContentAsync(string text, string contentType = "text/plain", int statusCode = 200)
        {
            var contentResult = new ContentResult()
            {
                Content = text,
                ContentType = contentType,
                StatusCode = statusCode
            };
            return await Task.FromResult(contentResult);
        }

        /// <summary>
        /// 返回空结果
        /// </summary>
        /// <param name="controller"></param>
        /// <returns></returns>
        public async Task<IActionResult> EmptyAsync()
        {
            return await Task.FromResult(new EmptyResult());
        }

        /// <summary>
        /// 返回下载结果
        /// </summary>
        /// <param name="controller"></param>
        /// <param name="fileContent">下载时的文件名称</param>

        /// <returns></returns>
        public async Task<IActionResult> DownloadAsync(string fileDownloadName,
            byte[] fileContent,
            string contentType)
        {
            return await Task.FromResult(new FileContentResult(fileContent, contentType) { FileDownloadName = fileDownloadName });
        }

        /// <summary>
        /// 返回下载结果
        /// </summary>
        /// <param name="controller"></param>
        /// <param name="fileName">内容文件地址</param>

        /// <returns></returns>
        public async Task<IActionResult> DownloadAsync(string fileName,
            string contentType)
        {
            return await Task.FromResult(new VirtualFileResult(fileName, contentType)
            {
                EnableRangeProcessing = true,
                FileDownloadName = PathUtil.GetFileName(fileName)
            });
        }
        /// <summary>
        /// 返回流结果
        /// </summary>

        /// <returns></returns>
        public async Task<IActionResult> DownloadAsync(string fileDownloadName,
            Stream fileStream,
            string contentType
            )
        {
            return await Task.FromResult(new FileStreamResult(fileStream, contentType)
            {
                EnableRangeProcessing = true,
                FileDownloadName = fileDownloadName
            });
        }

        public async Task<IActionResult> RedirectAsync(string url)
        {
            return await Task.FromResult(new RedirectResult(url));
        }
