Question

我有一个Unity项目，我将数据存储到本地文件夹。我想使用ftp客户端将这些数据发送到服务器。我如何在Unity中执行此操作？这是一种方法吗？我可以使用任何库或像filezilla这样的软件吗？

我遇到了webRequest class，但我不确定如何使用它。我从答案中看到了建议的代码但是我不确定我将如何使用它。我在FTPupload函数内的onGUI()函数中收到错误。

你走在正确的轨道上。我想这是你正在寻找的用法： https://github.com/mminer/ftpuploader-unity/blob/master/Editor/Uploader.cs

向下滚动到Upload方法;我使用了很多次，效果很好。

[编辑] 以下是上述代码的示例，可以直接在Unity项目中使用：

    {
        Upload("PATH_TO_YOUR_FILE", "YOUR_FTP_SERVER_ADRESS", "YOUR_USERNAME", "YOUR_PASSWORD", "ANY_SUB_FOLDER");
    }

    /// <summary>

    static void Upload(string filename, string server, string username, string password, string initialPath)
    {
        Debug.Log("Upload started.");

        var file = new FileInfo(filename);
        var address = new Uri("ftp://" + server + "/" + Path.Combine(initialPath, file.Name));
        var request = FtpWebRequest.Create(address) as FtpWebRequest;

        // Upload options:

        // Provide credentials
        request.Credentials = new NetworkCredential(username, password);

        // Set control connection to closed after command execution
        request.KeepAlive = false;

        // Specify command to be executed
        request.Method = WebRequestMethods.Ftp.UploadFile;

        // Specify data transfer type
        request.UseBinary = true;

        // Notify server about size of uploaded file
        request.ContentLength = file.Length;

        // Set buffer size to 2KB.
        var bufferLength = 2048;
        var buffer = new byte[bufferLength];
        var contentLength = 0;

        // Open file stream to read file
        var fs = file.OpenRead();

        try
        {
            // Stream to which file to be uploaded is written.
            var stream = request.GetRequestStream();

            // Read from file stream 2KB at a time.
            contentLength = fs.Read(buffer, 0, bufferLength);

            // Loop until stream content ends.
            while (contentLength != 0)
            {
                //Debug.Log("Progress: " + ((fs.Position / fs.Length) * 100f));
                // Write content from file stream to FTP upload stream.
                stream.Write(buffer, 0, contentLength);
                contentLength = fs.Read(buffer, 0, bufferLength);
            }

            // Close file and request streams
            stream.Close();
            fs.Close();
        }
        catch (Exception e)
        {
            Debug.LogError("Error uploading file: " + e.Message);
            return;
        }

        Debug.Log("Upload successful.");
    }
