上传表格:
<form asp-action="Upload" asp-controller="Uploads" enctype="multipart/form-data">
<input type="file" name="file" maxlength="64" />
<button type="submit">Upload</button>
Controller /文件上传:
public void Upload(IFormFile file){
using (WebClient client = new WebClient())
{
client.Credentials = new NetworkCredential("xxxx", "xxxx");
client.UploadFile("ftp://xxxx.xxxx.net.uk/web/wwwroot/images/", "STOR", file.FileName);
}
}
问题:
出现错误“找不到文件 xxxx”。我知道问题是它试图在 FTP 服务器上查找 "C:\path-to-vs-files\examplePhoto.jpg"
文件,这显然不存在。我一直在看这里的许多问题/答案,我认为我需要某种 FileStream
读/写 cod。但我目前还没有完全理解这个过程。
使用IFormFile.CopyTo
或 IFormFile.OpenReadStream
访问上传文件的内容。
将其与 WebClient.OpenWrite
合并:
public void Upload(IFormFile file)
{
string url = "ftp://ftp.example.com/remote/path/file.zip";
using (WebClient client = new WebClient())
{
client.Credentials = new NetworkCredential("xxxx", "xxxx");
using (var ftpStream = client.OpenWrite(url))
{
file.CopyTo(ftpStream);
}
}
}
或者,使用 FtpWebRequest
:
public void Upload(IFormFile file)
{
string url = "ftp://ftp.example.com/remote/path/file.zip";
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(url);
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.UploadFile;
using (Stream ftpStream = request.GetRequestStream())
{
file.CopyTo(ftpStream);
}
}
