I have function for uploading a file to ftp and I woud like to know the equivalent function for downloading and renaming the file. I have no experience with c# I only use this functions to post them to azure function and then consume them in BC. I would be thankful is anyone could show or guide me to have the equivalent function for the download and the one for rename; Below is the upload function :
Share
Report [FunctionName("FtpStor")]
public static async Task Run(
[HttpTrigger(AuthorizationLevel.Anonymous, "post", Route = null)] HttpRequest req,
ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
string fileUri = data.fileUri;
string username = data.username;
string password = data.password;
string filename = data.filename;
string ContentFileToBase64String = data.ContentFileToBase64String;
var bytes = Convert.FromBase64String(ContentFileToBase64String);
Stream fileStream = new MemoryStream(bytes);
//Upload to FTP
FtpWebRequest ftpWebRequest = (FtpWebRequest)WebRequest.Create(fileUri);
ftpWebRequest.Method = WebRequestMethods.Ftp.UploadFile;
ftpWebRequest.Credentials = new NetworkCredential(username,password);
ftpWebRequest.UsePassive = true;
using (Stream requestStream = ftpWebRequest.GetRequestStream())
{
await fileStream.CopyToAsync(requestStream);
}
fileStream.Dispose();
using (FtpWebResponse response = (FtpWebResponse)await ftpWebRequest.GetResponseAsync())
{
string result = response.StatusDescription;
return response.StatusCode == FtpStatusCode.ClosingData
? (ActionResult)new OkObjectResult(result)
: new BadRequestObjectResult(result);
}
}
And this the function that i'm using to call the ftp download :
RequestContent.Clear();
Client.Clear();
fileuri := 'ftp://*****:21/TEST/file.txt';
uri := 'https://*****.azurewebsites.net/api/FtpDownload?';
RequestBody := '{';
RequestBody = 'fileUri:"' fileUri '",';
RequestBody = 'username:"******",';
RequestBody = 'password:"*****",';
RequestBody = '}';
RequestContent.WriteFrom(RequestBody);
RequestContent.GetHeaders(RequestHeaders);
RequestHeaders.Clear();
RequestHeaders.Add('Content-Type', 'application/json');
RequestMessage.Content := RequestContent;
Client.Post(uri, RequestContent, ResponseMessage);
ResponseMessage.Content().ReadAs(OutputString);
tempblob.CreateInStream(FromInStream);
FromInStream.Read(OutputString);
Fromfile := 'file.txt';
DownloadFromStream(FromInStream, '', '', '', Fromfile);
It's probably not possible with Fluent FTP.
There's FtpClient.Download method which takes Stream.

public bool Download(Stream outStream, string remotePath, IProgress<double> progress = null)
But it does not look like there's API to get "blob upload Stream".
Conversely, you cannot get "FTP download Stream" from FluentFTP (which you would be able to use with blob API).
But you can use native .NET FtpWebRequest FTP client, which has API to get "FTP download Stream":
public static async System.Threading.Tasks.Task RunAsync([TimerTrigger("0 */1 * * * *")]TimerInfo myTimer, ILogger log)
{
var ftpUserName = "xxxxxx";
var ftpPassword = "xxxxxxxxx";
var filename = "test.png";
string blobConnectionString = "xxxxxxx";
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(blobConnectionString);
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
CloudBlobContainer container = blobClient.GetContainerReference("myblobcontainer");
FtpWebRequest fileRequest = (FtpWebRequest)WebRequest.Create("">ftp://xxxxxx/" + filename);
fileRequest.Method = WebRequestMethods.Ftp.DownloadFile;
fileRequest.Credentials = new NetworkCredential(ftpUserName, ftpPassword);
FtpWebResponse fileResponse = (FtpWebResponse)fileRequest.GetResponse();
Stream fileStream = fileResponse.GetResponseStream();
CloudBlockBlob blockBlob = container.GetBlockBlobReference(filename);
await blockBlob.UploadFromStreamAsync(fileStream);
log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
}
