如何在FTP服务器上传文件和加密 [英] How to upload files and encrypt in FTP server

问题描述

已编写下面的代码将文件从本地系统复制到ftp服务器，同样我需要选择多个文件并将其上传到服务器中。当我上传文件时，它应该被转换为加密文件，任何建议，我也写了加密代码。



我尝试过：

公共类WebRequestGetExample 
 {
 public static void Main（）
 {
 //获取用于与服务器通信的对象。 
 FtpWebRequest request =（FtpWebRequest）WebRequest.Create（ftp：//192.1....../ftp.txt）; request.Method = WebRequestMethods.Ftp.UploadFile; 
 //此示例假定FTP站点使用匿名登录。 
 request.Credentials = new NetworkCredential（username，password）; 
 //将文件内容复制到请求流。 
 byte [] fileContents; 
使用（StreamReader sourceStream = new StreamReader（E：\\Anusha \\\\\ [@]）
 {
 fileContents = Encoding.UTF8.GetBytes（sourceStream.ReadToEnd） （））; 
} 
 request.ContentLength = fileContents.Length; 
 using（Stream requestStream = request.GetRequestStream（））
 {
 requestStream.Write（fileContents，0，fileContents.Length）; 
} 
使用（FtpWebResponse response =（FtpWebResponse）request.GetResponse（））
 {
 Console.WriteLine（上传文件完成，状态{0}，response.StatusDescription ）; 
} 
} 
} 

解决方案

WebClient 提供简单易用使用FTP上传和下载的方法，请参阅： c＃ - 从上传文件和下载文件FTP - 堆栈溢出 [ ^ ]

您可以使用.NET中的 System.Security.Cryptography 命名空间进行加密。

这是一篇关于CodeProject加密的好文章： C＃中的Swanky加密/解密 [ ^ ]

have written below code to copy file from local system to ftp server , similarly i need to select multiple files and upload them in server . While i upload the files it should be converted as encrypted files, any suggestions, i have written code for encryption also.

What I have tried:

public class WebRequestGetExample  
{  
public static void Main ()  
{  
// Get the object used to communicate with the server.  
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://192.1....../ftp.txt"); request.Method =WebRequestMethods.Ftp.UploadFile;  
// This example assumes the FTP site uses anonymous logon.  
request.Credentials = new NetworkCredential("username", "password");  
// Copy the contents of the file to the request stream.  
byte[] fileContents;  
using (StreamReader sourceStream = new StreamReader("E:\\Anusha\\ftp.txt"))  
{  
fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());  
}  
request.ContentLength = fileContents.Length;  
using (Stream requestStream = request.GetRequestStream())  
{  
requestStream.Write(fileContents, 0, fileContents.Length);  
}  
using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())  
{  
Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);  
}  
}  
}

解决方案

WebClient offers an easy way to upload and download using FTP, see: c# - Upload file and download file from FTP - Stack Overflow[^]
You can encrypt using the System.Security.Cryptography namespace in .NET.
Here is a good article about encryption on CodeProject: Swanky Encryption/Decryption in C#[^]
