Question

当我尝试使用Azure WebJobs的FTP发送文件时，我遇到1个问题。交替抛出“远程服务器返回错误：（530）未登录。”，我的代码在localhost（在开发计算机上）上运行良好。

我已经阅读了所有这些文章，但没有找到方法：

FTPWebRequest 530 Error: Not Logged in issue

FTP The remote server returned an error: (530) Not logged in

Fetching files from FTP server via Azure webjobs

Ftp to external server in azure webjob not working

其他，但是我的应用程序服务中只有1个webjobs，并且在作业运行时CPU占30％。 File download from FTP fails only in Azure web app

编辑：代码制作目录

CMake Error: The source directory "C:/Users/pro12/Desktop/libwebsockets/build" does not appear to contain CMakeLists.txt.

代码发送文件：

[ngStyle]="{'height': 'calc(100% - 57px)'"}

并在Azure WebApp WebJobs中运行代码时记录日志（失败）： https://pastebin.com/vgTxqT5p

并在我在本地计算机上运行代码时记录（工作出色）： https://pastebin.com/hBpum8T0

我认为解决方法是针对WebJobs应用程序样式的，而正常功能并未等待。我将更改我的代码，以对所有WebJobs程序使用Async Await方法。

有什么办法吗？提前谢谢。

不好的方式（我不喜欢这样），但是它是有效的.....：

像这样更改Make Directory功能：

public static void MakeFTPDir(string publishUrl, string userName, string userPWD, string directory)
    {
        FtpWebRequest reqFTP = null;
        Stream ftpStream = null;

        string[] subDirs = directory.Split('/');

        string currentDir = publishUrl;

        foreach (string subDir in subDirs)
        {
            bool isNotCreated = true;
            int iTentative = 0;
            currentDir = currentDir + "/" + subDir;
            while (isNotCreated)
            {
                iTentative++;
                try
                {
                    reqFTP = (FtpWebRequest)FtpWebRequest.Create(currentDir);
                    reqFTP.Method = WebRequestMethods.Ftp.MakeDirectory;
                    reqFTP.UseBinary = true;
                    reqFTP.UsePassive = true;
                    reqFTP.KeepAlive = true;
                    reqFTP.Credentials = new NetworkCredential(userName, userPWD);
                    FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
                    ftpStream = response.GetResponseStream();
                    ftpStream.Close();
                    response.Close();
                }
                catch(WebException webException)
                {
                    FtpWebResponse excWebResponse = (FtpWebResponse)webException.Response;
                    if(excWebResponse.StatusCode == FtpStatusCode.NotLoggedIn)
                    {
                        Console.WriteLine("WebException ==> NotLoggedIn >> Tentative :" + iTentative);
                        isNotCreated = true;
                    }
                    else
                    {
                        Console.WriteLine(webException.Message);
                        isNotCreated = false;
                    }
                }
                catch (Exception exception)
                {
                    FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
                    if (response.StatusCode == FtpStatusCode.NotLoggedIn)
                    {
                        Console.WriteLine("Exception ==> NotLoggedIn >> Tentative :" + iTentative);
                        isNotCreated = true;
                    }
                    else
                    {
                        Console.WriteLine(exception.Message);
                        isNotCreated = false;
                    }
                }
            }
        }
    }

更改发送文件功能

 public static bool SendFtpFile(string publishUrl, string userName, string userPWD, string localFileName)
    {
        bool isNotCreated = true;
        int iTentative = 0;
        while (isNotCreated)
        {
            iTentative++;
            try
            {
                using (WebClient client = new WebClient())
                {
                    client.Credentials = new NetworkCredential(userName, userPWD);
                    client.UploadFile(publishUrl, "STOR", localFileName);
                    return true;
                }
            }
            catch (WebException webException)
            {
                FtpWebResponse excWebResponse = (FtpWebResponse)webException.Response;
                if (excWebResponse.StatusCode == FtpStatusCode.NotLoggedIn)
                {
                    Console.WriteLine("WebException ==> NotLoggedIn >> Tentative :" + iTentative);
                    isNotCreated = true;
                }
                else
                {
                    Console.WriteLine(webException.Message);
                    return false;
                }
            }
            catch (Exception exception)
            {
                Console.WriteLine(exception.Message);
                return false;
            }
        }
        return true;
    }

更改IfFileExistOnServer：

public static bool CheckIfFileExistsOnServer(string publishUrl, string userName, string userPWD, string fileName)
    {
        bool isNoCheck = true;
        int iTentative = 0;
        string azureBotUrl = publishUrl + "/" + fileName;

        while (isNoCheck)
        {
            iTentative++;
            try
            {
                var request = (FtpWebRequest)WebRequest.Create(azureBotUrl);
                request.Credentials = new NetworkCredential(userName, userPWD);
                request.UseBinary = true;
                request.UsePassive = true;
                request.KeepAlive = true;
                request.Method = WebRequestMethods.Ftp.GetFileSize;
                FtpWebResponse response = (FtpWebResponse)request.GetResponse();
                return true;
            }
            catch (WebException webException)
            {
                FtpWebResponse excWebResponse = (FtpWebResponse)webException.Response;
                if (excWebResponse.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable)
                    return false;
                if (excWebResponse.StatusCode == FtpStatusCode.NotLoggedIn)
                {
                    Console.WriteLine("WebException ==> NotLoggedIn >> Tentative :" + iTentative);
                    isNoCheck = true;
                }
                else
                {
                    return false;
                }
            }
        }
        return false;
    }

并更改RenameFileOnServer：

public static bool RenameFileOnServer(string publishUrl, string userName, string userPWD, string sourceFileName, string newFileName)
    {
        bool isNoRenameFile = true;
        int iTentative = 0;
        FtpWebRequest ftpRequest = null;
        FtpWebResponse ftpResponse = null;
        string azureBotUrl = publishUrl + "/" + sourceFileName;
        while (isNoRenameFile)
        {
            iTentative++;
            try
            {
                ftpRequest = (FtpWebRequest)WebRequest.Create(azureBotUrl);
                ftpRequest.Credentials = new NetworkCredential(userName, userPWD);
                ftpRequest.UseBinary = true;
                ftpRequest.UsePassive = true;
                ftpRequest.KeepAlive = true;
                ftpRequest.Method = WebRequestMethods.Ftp.Rename;
                ftpRequest.RenameTo = newFileName.Split('\\')[newFileName.Split('\\').Length - 1];
                ftpResponse = (FtpWebResponse)ftpRequest.GetResponse();
                ftpResponse.Close();
                ftpRequest = null;
                return true;
            }
            catch (WebException webException)
            {
                FtpWebResponse excWebResponse = (FtpWebResponse)webException.Response;
                if (excWebResponse.StatusCode == FtpStatusCode.NotLoggedIn)
                {
                    Console.WriteLine("WebException ==> NotLoggedIn >> Tentative :" + iTentative);
                    isNoRenameFile = true;
                }
                else
                {
                    return false;
                }
                Console.WriteLine(webException.Message);
            }
            catch (Exception)
            {
                return false;
            }
        }
        return false;
    }
