关于FTP、FTPS 与 SFTP 简介见另外一篇转载的文章,讲的比较详细,此文不在另外描述.

FTPS在微软官网寥寥数笔,看完也一头雾水,无奈找了一通,找了到了一份开源代码,研究了一通发觉可用,至此记录.

一句未改得原始代码上传至,以便哪天找不到国外网站资源.

第一步:打开源码,VS报弹框不用理,直接确定即可.在原始代码中直接rebuild编译FTPSClient,生成"AlexPilotti.FTPS.Client.dll"和“AlexPilotti.FTPS.Client.XML" 这两个文件导入至所需得项目路径下,直接引用就可.
第二步:编译FTPSClientCmdApp,生成ftps.exe,打开cmd命令窗口查看工具是否可正常使用
ftps -h 10.131.128.6 -U user -P password -ssl CredentialsRequired -g /Modules/ZW01TLAA.IMZ C:\Users\XXX\Desktop\mytest第三步:在自己的项目中,导入"AlexPilotti.FTPS.Client.dll"和“AlexPilotti.FTPS.Client.XML"后,需要修改代码才能正确使用.核心代码修改如下:
using System; using System.Data; using System.IO; using BaseLibrary.ExecutionResults; using System.Text; using System.Net; using System.Net.Security; using System.Security.Cryptography.X509Certificates; using BaseLibrary.Config; using AlexPilotti.FTPS.Client; public class readfile { public string strServerPath; public FTPSClient client; public void initFTPS() { CCfg ccfg = new CCfg(); strServerPath = ccfg.GetValue("serverPath");//modules string user = ccfg.GetValue("user");//"ftpsuser" string password = ccfg.GetValue("password");//"password" string ip = ccfg.GetValue("ip");//"192.168.1.1" client = new FTPSClient(); NetworkCredential credential = new NetworkCredential(user, password); ESSLSupportMode sslRequestSupportMode = ESSLSupportMode.DataChannelRequested; X509Certificate x509ClientCert = null; string sslClientCertPath = null; int sslMinKeyExchangeAlgStrength = 0; int sslMinCipherAlgStrength = 0; int sslMinHashAlgStrength = 0; int timeout = 120; bool useCtrlEndPointAddressForData = false; EDataConnectionMode dataConnectionMode = EDataConnectionMode.Passive; if (sslClientCertPath != null) { x509ClientCert = X509Certificate.CreateFromCertFile(sslClientCertPath); } client.Connect(ip, 21, credential, sslRequestSupportMode, new RemoteCertificateValidationCallback(ValidateTestServerCertificate), x509ClientCert, sslMinKeyExchangeAlgStrength, sslMinCipherAlgStrength, sslMinHashAlgStrength, timeout * 1000, useCtrlEndPointAddressForData, dataConnectionMode); } enum EInvalidSslCertificateHandling { Refuse, Accept, Prompt } private bool ValidateTestServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { bool certOk = false; EInvalidSslCertificateHandling sslInvalidServerCertHandling = EInvalidSslCertificateHandling.Prompt; if (sslPolicyErrors == SslPolicyErrors.None) certOk = true; else { Console.Error.WriteLine(); if ((sslPolicyErrors & SslPolicyErrors.RemoteCertificateChainErrors) > 0) Info("WARNING: SSL/TLS remote certificate chain warning"); if ((sslPolicyErrors & SslPolicyErrors.RemoteCertificateNameMismatch) > 0) Info("WARNING: SSL/TLS remote certificate name mismatch"); if ((sslPolicyErrors & SslPolicyErrors.RemoteCertificateNotAvailable) > 0) Info("WARNING: SSL/TLS remote certificate not available"); if (sslInvalidServerCertHandling == EInvalidSslCertificateHandling.Accept) certOk = true; } if (!certOk) { Info("SSL/TLS Server certificate details:"); Info(GetCertificateInfo(certificate)); } if (!certOk && sslInvalidServerCertHandling == EInvalidSslCertificateHandling.Prompt) { //certOk = Utility.ConsoleConfirm("Accept invalid server certificate? (Y/N)"); certOk = true; } return certOk; } public static string GetCertificateInfo(X509Certificate certificate) { StringBuilder certInfo = new StringBuilder(); //Note: certificate.ToString() returns just the class name in Mono 2.0 // Simulate the .Net frameworks 2.0 ToString() certInfo.AppendLine("[Subject]"); certInfo.AppendLine(certificate.Subject); certInfo.AppendLine(""); certInfo.AppendLine("[Issuer]"); certInfo.AppendLine(certificate.Issuer); certInfo.AppendLine(""); certInfo.AppendLine("[Serial Number]"); certInfo.AppendLine(certificate.GetSerialNumberString()); certInfo.AppendLine(""); certInfo.AppendLine("[Not Before]"); certInfo.AppendLine(certificate.GetEffectiveDateString()); certInfo.AppendLine(""); certInfo.AppendLine("[Not After]"); certInfo.AppendLine(certificate.GetExpirationDateString()); certInfo.AppendLine(""); certInfo.AppendLine("[Thumbprint]"); certInfo.AppendLine(certificate.GetCertHashString()); return certInfo.ToString(); } public void Download(string strServerFile,string strLocalFile) { if (!File.Exists(strLocalFile)) { if (client == null) { initFTPS(); } Info($"{strServerFile} is copying."); client.GetFile($"/{strServerPath}/{strServerFile}", strLocalFile); } else { Info($"{strServerFile} is already existed!"); } } }是不是相当简单呢?
