详解：基于WEB API实现批量文件由一个服务器同步快速传输到其它多个服务器功能

文件同步传输工具比较多，传输的方式也比较多，比如：FTP、共享、HTTP等，我这里要讲的就是基于HTTP协议的WEB API实现批量文件由一个服务器同步快速传输到其它多个服务器这样的一个工具（简称：一端到多端的文件同步工具）

一、设计原理：

1.使用的技术：WinForm、WebApi

1.1 WinForm：为程序主界面，作为一端（一个源文件服务器）同步传输到多端（多个目的文件服务器）文件的业务处理中介；程序内部主要通过System.Timers.Timer+HttpClient来实现定时执行文件同步传输业务；

1.2 WebApi：实现通过HTTP协议批量下载或批量上传多个文件（文件同步传输的核心业务逻辑）；MultipartContent作为批量下载或批量上传的唯一媒介。

2.实现思路：

2.1客户端（WinForm程序主界面）通过HttpClient向源文件服务器目录URL发送GET请求；

2.2源文件服务器服务端（WebApi）的GetFiles方法接收到GET请求后，按照web.config中配置的源文件路径递归获取所有文件的字节信息并转换成MultipartFormDataContent对象后返回；（即：实现了批量下载）

2.3客户端（WinForm程序主界面）将响应的结果显式转换并生成对应的目的文件服务器数量的多文件流内容（MultipartContent）对象列表，以便后续用于批量上传；

2.4客户端（WinForm程序主界面）启用并行循环（Parallel.ForEach）来遍历目的文件服务器目录URL（采用并行循环是为了达到同时向多个目的文件服务器批量上传文件的效果，从而提高运行效率），在循环遍历中，每次将2.3中获得的多文件流内容（MultipartContent）通过HttpClient向目的文件服务器目录URL发送POST请求；

2.5目的文件服务器服务端（WebApi）的SaveFiles方法接收到POST请求后，解析2.4中POST过来的多文件流内容（MultipartContent），并循环遍历文件流，在循环遍历中，按照web.config中配置的上传文件路径，将文件流输出保存到指定的文件路径下，同时生成文件保存成功与失败的日志信息字典，最后返回该字典。（即：实现了批量上传保存）

2.6客户端（WinForm程序主界面）将响应的结果显式转换成保存成功与失败的日志信息字典，并添加到线程安全的无序集合对象中；（采用线程安全的无序集合对象是因为存在多线程并发更新的风险）

2.7客户端（WinForm程序主界面）等待所有并行循环同步上传执行完毕后，根据最后得到的保存成功与失败的日志信息无序集合对象，获得所有目的文件服务器全部保存成功文件名列表及保存成功与失败的日志信息列表（判断是否全部上传成功：若某个文件应上传到5个目的文件服务器，实际成功上传5个，则视为成功，否则有一个未上传成功则视为失败），然后通过HttpClient向源文件服务器目录URL发送PUT请求删除源文件服务器中的同名文件，向源文件服务器LOG URL发送POST请求将此次文件同步传输的日志保存到源文件服务器目录中

2.8源文件服务器服务端（WebApi）RemoveFiles方法接收到PUT请求后，循环遍历PUT过来的保存成功文件名列表，依次删除同名文件（含子目录），WriteLog方法接收到POST请求后，直接将POST过来的日志信息列表输出保存至源文件服务器web.config中配置的LOG文件路径；为了避免日志无限增大及考虑日志的使用价值，日志文件每天重新覆盖生成新的文件；

3.业务流程图：

序列图：

二、使用说明：

1.将KyFileSyncTransfer.Api项目分别发布到源文件服务器、目的文件服务器；

2.修改源文件服务器服务端（WebApi）web.config中的AppSettings节点，配置FileSyncDirectory（源文件存放目录）、LogDirectory（日志文件保存路径，仅限源文件服务器服务端配置），这两个路径支持当前项目的子目录（即：配置时使用~/）或其它路径（其它路径则需直接配置完整的物理路径）；修改目的文件服务器服务端（WebApi）web.config中的AppSettings节点，配置FileSyncDirectory（上传文件存放目录），这个路径支持当前项目的子目录（即：配置时使用~/）或其它路径（其它路径则需直接配置完整的物理路径）

注：为了能够支持大文件批量上传，同时需修改请求内容长度限制，如下设置成最大批量上传1.9G：

3.将客户端（WinForm程序主界面）部署到某台服务器上（只要能够访问源文件服务器、目的文件服务器即可，也可以他们服务器上的任意一台），然后开启客户端（WinForm程序主界面），将上述的源文件服务器服务端URL（http://源文件服务器Host/Api/Files）及多个目的文件服务器服务端URL（http://目的文件服务器Host/Api/Files）录入到程序预设的地方，设置好时间间隔，最后点击开启即可（需保持该程序一直处于运行中，可以最小化到任务栏，双击图标可以显示界面）；若需停止文件同步，点击停止按钮即可；若需查看运行日志，可以切换到运行日志页签浏览。

4.以上3步是完成了文件自动定时同步传输的所有工作，后续只需要将需要同步的文件放到源文件服务器服务端web.config中的AppSettings节点设置的FileSyncDirectory（源文件存放目录）即可。

运行效果如下：

三、贴出主要的源代码

WebApiConfig：（增加全局token验证及全部采用json数据返回）

using System;
using System.Collections.Generic;
using System.Linq;

            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }

            config.Services.Replace(typeof(IContentNegotiator), new JsonContentNegotiator(jsonFormatter));
        }

JsonContentNegotiator：

    public class JsonContentNegotiator : IContentNegotiator

            return result;
        }
    }

TokenAuthentificationAttribute：

    public class TokenAuthentificationAttribute : AuthorizationFilterAttribute
    {
        public override void OnAuthorization(System.Web.Http.Controllers.HttpActionContext actionContext)
        {
            if (actionContext.ActionDescriptor.GetCustomAttributes<AllowAnonymousAttribute>().Count > )

                return;
            }

            //HttpContextBase context = (HttpContextBase)actionContext.Request.Properties["MS_HttpContext"];//获取传统context
            //HttpRequestBase request = context.Request;//定义传统request对象  

            IEnumerable<string> requestToken = null;
            if (actionContext.Request.Headers.TryGetValues("token", out requestToken) && BaseUtility.ValidateToken(requestToken.ElementAt()))
            {
                base.OnAuthorization(actionContext);
            }
            else
            {
                actionContext.Response = actionContext.Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "token验证未通过。");
                return;
            }

        }

特别说明：若客户端需要直接使用ReadAsAsync<T>将响应的结果反序列化成对象，则Newtonsoft.Json应采用6.0.0.0版本，这个是WebApi框架默认使用的版本，若单独通过NuGet引用可能是最新的9.0版本，会报错，这点注意；

另外文中为何采用Winform作为客户端，目的是可以实时查看运行结果，若没有这个需求，那么就可以采用Windows服务程序即可,看个人意愿了。

还有人可能认为，批量上传与下载采取打包上传与打包下载更快，这个我认为看各人的实际需求。

看到大家都想要源代码，其实源代码上面都有复制到项目中即可，但为了便于大家测试，故我也将GIT仓库地址告诉给大家：[e-mail]:zuowj/KyFileSyncTransfer.git，大家如有需要可以下载或查看。
