這次給大家?guī)?lái)FTP的文件管理，對(duì)FTP文件進(jìn)行管理的
注意事項(xiàng)有哪些，下面就是實(shí)戰(zhàn)案例，一起來(lái)看一下。
因?yàn)榫W(wǎng)站有下載文件需要和網(wǎng)站分離，使用到了FTP管理文件，這里做一個(gè)簡(jiǎn)單的整理。
1.安裝FTP
和安裝iis一樣。全部勾選。
設(shè)置站點(diǎn)名稱和路徑。
設(shè)置ip。
身份授權(quán)選擇所有用戶，可以讀寫(xiě)。
完成之后 IIS就會(huì)出現(xiàn)：
2.添加FTP用戶
計(jì)算機(jī)-->管理-->本地用戶和組。 添加用戶，描述為FTP。
這里要設(shè)置用戶的密碼方式，去掉“用戶下次登錄時(shí)必須更改密碼”的選項(xiàng)。
不然會(huì)登錄不成功。報(bào)530錯(cuò)誤。
3.測(cè)試登錄
ftp ip 就可以訪問(wèn)。顯示230 user logged in 表示登錄成功。
4.上傳下載

主要是通過(guò)創(chuàng)建FtpRequest來(lái)處理Ftp相關(guān)請(qǐng)求。
public static FtpWebRequest FtpRequest(string requstUrl,string method,bool closedResponse=false)
{ var reqFtp = (FtpWebRequest) WebRequest.Create(new Uri(requstUrl)); //設(shè)置連接到FTP的帳號(hào)密碼
reqFtp.Credentials = new NetworkCredential(Username, Password); //設(shè)置請(qǐng)求完成后是否保持連接
reqFtp.KeepAlive = false; //指定執(zhí)行命令
reqFtp.Method = method; //指定數(shù)據(jù)傳輸類(lèi)型
reqFtp.UseBinary = true; if (closedResponse)
{ var resp=reqFtp.GetResponse();
resp.Close();
} return reqFtp;
}因?yàn)樵贛VC網(wǎng)站中使用的文件流的方式。
下載：
public static Stream Download(string remoteFile)
{ var ftpRequest = FtpRequest(Path + remoteFile, WebRequestMethods.Ftp.DownloadFile); var response = (FtpWebResponse)ftpRequest.GetResponse();
Stream ftpStream = response.GetResponseStream(); return ftpStream;
}調(diào)用：
public ActionResult DownloadFileFromFtp()
{ var filepath = "DIAView//simple.png"; var stream = FtpHelper.Download(filepath); return File(stream, FileHelper.GetContentType(".png"),"test.png");
}上傳：
public static bool UpLoad(Stream localFileStream, string remoteFile)
{ bool result = true; try
{ var ftpRequest = FtpRequest(Path + remoteFile, WebRequestMethods.Ftp.UploadFile); var ftpStream = ftpRequest.GetRequestStream(); var byteBuffer = new byte[bufferSize]; int bytesSent = localFileStream.Read(byteBuffer, 0, bufferSize); try
{ while (bytesSent != 0)
{
ftpStream.Write(byteBuffer, 0, bytesSent);
bytesSent = localFileStream.Read(byteBuffer, 0, bufferSize);
}
} catch (Exception ex)
{
Console.WriteLine(ex.ToString());
result = false;
}
localFileStream.Close();
ftpStream.Close();
} catch (Exception ex)
{
Console.WriteLine(ex.ToString());
result = false;
} return result;
}調(diào)用：
[HttpPost] public JsonResult UploadFile(HttpPostedFileBase fileData)
{ if (fileData != null)
{ string fileName = Path.GetFileName(fileData.FileName);// 原始文件名稱
string saveName = Encrypt.GenerateOrderNumber() +"_"+fileName;
FtpHelper.UpLoad(fileData.InputStream, "DIAView" + "/" + saveName); return Json(new { Success = true, FileName = fileName, SaveName = saveName}, JsonRequestBehavior.AllowGet);
} return Json(new { Success = false, Message = "請(qǐng)選擇要上傳的文件！" }, JsonRequestBehavior.AllowGet);
}Ftp還可以設(shè)置不同用戶有不同的目錄，是以為記
