如何将上传的文件移动到远程服务器上的文件夹 [英] How to move uploaded file to a folder on remote server

问题描述

我正在使用vs2008.我需要将文件上传到远程服务器.我的站点上有一个名为文件"的文件夹，我应该将所有上传的文件移到那里.

当前，当我使用

Hi,
I''m using vs2008. I need to upload a file to a remote server.there is a folder called ''Files'' on my site and I''m supposed to move all uploaded files there.

Currently, when I use the

myFile.PostedFile.SaveAs()

方法时，所有方法在本地都可以正常工作.但是当我上传到远程服务器时，就会出现问题.

我已授予该文件夹适当的权限，但是myFile.PostedFile.SaveAs()似乎总是可以看到我的本地目录.

这是:

method, all works well locally. But when I upload to my remote server, there goes the issue.

I have given the folder appropriate permissions, but myFile.PostedFile.SaveAs() seems to always see my local directory.

Here it is:

Dim dirPath As String = AppDomain.CurrentDomain.BaseDirectory + "Files"
myFile.PostedFile.SaveAs(dirPath & "/" & strFileNameOnly).

注意:myFile是上传文件控件的ID.

感谢任何帮助

Note: myFileis the id of the upload file control

Any help appreciated

推荐答案

我认为您应该通过证书来验证
例如: uploadRequest.Credentials = new NetworkCredential(user，pswd);

我已经用C Sharp编写了代码.我留给你翻译:

参见以下代码:

Hi,

I think you should pass a credential to validate
eg.: uploadRequest.Credentials = new NetworkCredential(user, pswd);

I have written a code in c sharp. I leave it to you to translate it:

See below code:

     public string Upload(string domainName, string targetRemoteUploadUrl, string fileName, string user, string pswd)
     {
         string result = string.Empty;
         Stream requestStream = null;
         FileStream fileStream = null;
         System.Net.FileWebResponse uploadResponse = null;
         try
         {
             string uriFile = HyperLinkToUrl(targetRemoteUploadUrl) + fileName.Substring((fileName.LastIndexOf("\\")));
             Uri processFile = new Uri(uriFile);

             System.Net.FileWebRequest uploadRequest = (System.Net.FileWebRequest)WebRequest.Create(processFile);

             if (!System.IO.Directory.Exists(targetRemoteUploadUrl))
             {
                  return "Error: " + "Target server/folder not exist...";
             }
             uploadRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile;

             //Since the FTP you are downloading to is secure, send
             //in user name and password to be able upload the file
             if (user != string.Empty && pswd == string.Empty)
             {
                    return "Error: " + "Password should not empty...";
             }
             if (user == string.Empty && pswd != string.Empty)
             {
                  return "Error: " + "User ID should not empty...";
             }

             if (user != string.Empty && pswd != string.Empty)
             {
                 uploadRequest.Credentials = new NetworkCredential(user, pswd);
                 bool valid = false;
                 PrincipalContext context = new PrincipalContext((ContextType.Domain), domainName);
                 valid = context.ValidateCredentials(user, pswd);
                 if (!valid)
                 {
                     return "Error: " + "Invalid User Id and/or Password...";
                 }
             }
             //UploadFile is not supported through an Http proxy
             //so we disable the proxy for this request.
             uploadRequest.Proxy = null;
             requestStream = uploadRequest.GetRequestStream();
             fileStream = File.Open(fileName, FileMode.Open);
             byte[] buffer = new byte[1024];
             int bytesRead;
             while (true)
             {
                 bytesRead = fileStream.Read(buffer, 0, buffer.Length);
                 if (bytesRead == 0)
                     break;
                 requestStream.Write(buffer, 0, bytesRead);
             }
             //The request stream must be closed before getting
             //the response.
             requestStream.Close();

         }
         finally
         {
             if (uploadResponse != null)
                 uploadResponse.Close();
             if (fileStream != null)
                 fileStream.Close();
             if (requestStream != null)
                 requestStream.Close();

         }
         return string.Empty;
     }

我已经尝试了全部转换，但在带下划线的地方出现了此错误.

I''ve tried converting all but I get this error at the underlined.

Dim context As PrincipalContext = New PrincipalContext((ContextType.DomainUnknown), domainName)
                valid = Context.ValidateCredentials(user, pswd)

PrincipalContext未定义

PrincipalContext not defined
