net core 写一段页面FTP下载文件的代码
以下是一个使用.NET Core编写的简单示例代码,用于从FTP服务器下载文件:
using System;
using System.IO;
using System.Net;
namespace FTPDownloadExample
{
class Program
{
static void Main(string[] args)
{
string ftpUrl = "ftp://example.com/file.txt";
string ftpUsername = "username";
string ftpPassword = "password";
string localFilePath = "C:\\Downloads\\file.txt";
try
{
// 创建FTP请求对象
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftpUrl);
request.Method = WebRequestMethods.Ftp.DownloadFile;
request.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
// 发送FTP请求并获取响应
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
// 打开本地文件用于写入
using (Stream responseStream = response.GetResponseStream())
using (FileStream fileStream = new FileStream(localFilePath, FileMode.Create))
{
// 从FTP响应流中读取数据并写入本地文件
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = responseStream.Read(buffer, 0, buffer.Length)) > 0)
{
fileStream.Write(buffer, 0, bytesRead);
}
}
Console.WriteLine("文件下载完成");
}
catch (Exception ex)
{
Console.WriteLine($"发生错误: {ex.Message}");
}
}
}
}
在上述代码中,你需要将ftpUrl替换为实际的FTP文件路径,ftpUsername和ftpPassword替换为FTP服务器的凭据,以及localFilePath替换为要保存下载文件的本地路径。然后,运行代码即可下载文件
