WebRequest from Unity project

本文关键字：project Unity from WebRequest | 更新日期: 2023-09-27 18:21:06

我有一个Unity项目，在其中我将数据存储到本地文件夹中。我想使用ftp客户端将这些数据发送到服务器。我怎么能在Unity做到这一点？这是一种方法吗？有没有像filezilla这样的库或软件可以让我执行？

我遇到了webRequest类，但我不确定如何使用它。我从答案中找到了建议的代码，但我也不确定该如何使用。我从位于onGUI()函数内的FTPupload函数中得到了一个错误。

你走在了正确的轨道上。我想这就是你想要的用法：https://github.com/mminer/ftpuploader-unity/blob/master/Editor/Uploader.cs

向下滚动到Upload方法；我用了很多次，效果很好。

[编辑]以下是可以直接在Unity项目中使用的上述代码示例：

            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)
            {

                // Write content from file stream to FTP upload stream.
