FTP远程服务器返回错误:(530)未登录 [英] FTP The remote server returned an error: (530) Not logged in

问题描述

我已经尝试解决这个问题超过4个小时，这让我发疯了.

I have been trying to solve this problem more than 4 hours, it is getting me crazy.

我创建了一个FTP，我想使用c#代码读取一些数据.

I created an FTP, and I wanna read some data using c# code.

当FTP没有用户名/密码访问权限时，一切正常.但是当我输入用户名和密码时，出现以下错误信息:远程服务器返回错误:(530)未登录.

when the FTP has no username/password access, everything works perfectly. but when I put username and password, i got this error message: The remote server returned an error: (530) Not logged in.

我尝试了所有关于stackoverflow和互联网的问题，例如:使用 .Normalize()，并使用 @username ，但我一直收到该错误.

I tried all the questions on stackoverflow and internet like: using .Normalize(), and using @username, but I keep getting that error.

这是我的代码:

foreach (string fileNameInFTP in directories)
                {
                    //                string fileNameInFTP2 = Path.GetFileNameWithoutExtension(fileNameInFTP);
                    if ((!haveWeAlreadyParsedThisFile(fileNameInFTP)) && (fileNameInFTP.Contains("CustsExport")) && (!fileNameInFTP.EndsWith("Empty.xml")) && (!fileNameInFTP.Contains("DelCustsExport")))
                    {
                        string file = FTPAddress + "/" + fileNameInFTP;
                        Console.WriteLine(file);
                        List<Customer> customersList =
                        (
                            from e in XDocument.Load(file).Root.Elements("cust")
                            select new Customer
                            {
                                MemeberID = (int)e.Attribute("memberid"),
                                CustomerID = (int)e.Attribute("custid"),
                                FirstName = (string)e.Attribute("fname"),
                                LastName = (string)e.Attribute("lname"),
                                ShowsNumber = (int)e.Attribute("count_noshow"),
                                VisitNumber = (int)e.Attribute("count_resos"),
                                Cancellation = (int)e.Attribute("count_cancel"),
                                MobileNumber = (string)e.Element("phone").Attribute("phonenumber")
                                /*Projects =
                                (
                                    from p in e.Elements("projects").Elements("project")
                                    select new Project
                                    {
                                        ProjectCode = (string)p.Element("code"),
                                        ProjectBudget = (int)p.Element("budget")
                                    }).ToArray()*/
                            }).ToList();

:请注意

，我能够访问FTP，因为 directories 变量是FTP中文件的列表，并且在调试代码时，我可以看到它有个文件，但此行中出现异常:

:please note

that I am able to access the FTP because the directories variable is the list of the files in the FTP, and when I debug the code, I can see that it has the files, but the exception accurs in this line:

                    List<Customer> customersList =
                    (
                        from e in XDocument.Load(file).Root.Elements("cust")
                        select new Customer
                        {
                            MemeberID = (int)e.Attribute("memberid"),
                            CustomerID = (int)e.Attribute("custid"),
                            FirstName = (string)e.Attribute("fname"),
                            LastName = (string)e.Attribute("lname"),
                            ShowsNumber = (int)e.Attribute("count_noshow"),
                            VisitNumber = (int)e.Attribute("count_resos"),
                            Cancellation = (int)e.Attribute("count_cancel"),
                            MobileNumber = (string)e.Element("phone").Attribute("phonenumber")
                            /*Projects =
                            (
                                from p in e.Elements("projects").Elements("project")
                                select new Project
                                {
                                    ProjectCode = (string)p.Element("code"),
                                    ProjectBudget = (int)p.Element("budget")
                                }).ToArray()*/
                        }).ToList();

换句话说:我能够读取文件的名称，但不能读取文件的内容

推荐答案

您可以在FTP URL上提供用户名和密码.例如，如果要从 ftp://ftp.foo.com 下载/path/filename ，则可以对用户名和密码进行如下编码:

You can supply the user name and password on the FTP URL. For example, if you want to download /path/filename from ftp://ftp.foo.com, you can encode the user name and password like this:

ftp://username:[e-mail]/path/filename

您应该能够为要下载的文件构造这样的URL.然后将该URL传递给 XDocument.Load .

You should be able to construct such a URL for the file you're trying to download. Then pass that URL to XDocument.Load.

但是请注意，密码是以明文形式发送的(即未加密等).

Note, however, that the password is sent in the clear (i.e. no encryption, etc.).
