JESAI.ClamAV.NetScanner

介绍

本项目是一个互联网云查杀方案,主要是利用TCP通信和ClamAV服务器交互,从而进行一些文件或者需要查杀的东西在云端杀毒,当然了,ClamAV也可以本地杀毒,使用本项目的前提,你要学会搭建ClamAV服务器。详情请看:https://www.clamav.net/。本类库目前是netcore3.1平台。

clamav

clamav是思科开源的一个杀毒引擎。ClamAV的®是一个开源(GPL)的各种情况,包括电子邮件扫描,Web扫描和终点的安全使用防病毒引擎。它提供了许多实用程序,包括灵活且可扩展的多线程守护程序,命令行扫描程序和用于自动数据库更新的高级工具。官网有完善的文档和工具,具体请自行研究。 输入图片说明

安装教程

  1. 首先你要去官网下载ClamAV程序,并在服务器或者本地部署ClamAV服务,然后启动服务。如下是启动效果。 输入图片说明
  2. nuget 包管理器搜索 JESAI.ClamAV.NetScannerCore 或者使用命令:Install-Package JESAI.ClamAV.NetScannerCore

使用说明

  1. Starup ConfigureServices里面添加 如果服务器配置,则添加
services.AddClamAVNetScanner();

如果需要自定义配置信息,则增加如下代码

 //IClamAvScannerConfiguration不配置的话,会默认
            //Host = "127.0.0.1",
            //Port = 3310,
            //MaxChunkSize = 2014,
            //MaxStreamSize = 26214400
            IClamAvScannerConfiguration configuration = new ClamAvScannerConfiguration()
            {
                Host="127.0.0.1",
                Port=3310,
                MaxChunkSize=2014,
                MaxStreamSize= 26214400
            };
            services.AddClamAVNetScanner(configuration);
            //也可以这样用
            //services.AddClamAVNetScanner((s) => { s.AddSingleton<IClamAvScannerConfiguration>(configuration); });

然后在services.AddControllersWithViews();后面加上services.AddClamAVNetScannerDynamicWebApi();可以不加,不加的话WebApi不会生效。

services.AddControllersWithViews();
services.AddClamAVNetScannerDynamicWebApi();

输入图片说明

  1. Starup Configure里面配置,这个主要是swagger用,如果不使用WebApi,也可以不配置。
app.UseClamAVNetScanner();
  1. 注入Client服务。
 private readonly IClamAVScannerClient ClamAVScannerClient;
 public HomeController(ILogger<HomeController> logger, IClamAVScannerClient clamAVScannerClient)
 {
       _logger = logger;
      ClamAVScannerClient = clamAVScannerClient;
 }

3.1 获取ClamAV服务器版本 GetVersionAsync;

3.2 在ClamAV服务器上执行PING命令。 PingAsync;

3.3 扫描ClamAV服务器上的文件/目录。 ScanFileOnServerAsync;

3.4 使用服务器上的多个线程扫描ClamAV服务器上的文件/目录。 ScanFileOnServerMultithreadedAsync;

3.5 将数据作为流发送到ClamAV服务器(Byte)。 SendAndScanFileAsync;

3.6 将数据作为流发送到ClamAV服务器(Byte)。 SendAndScanBytesAsync;

3.6 将数据作为流发送到ClamAV服务器(Stream)。 SendAndScanFileAsync;

3.7 从路径读取文件,然后将其作为流发送到ClamAV服务器。 SendAndScanFileAsync;
