c#之来自 Unity 项目的 WebRequest

我有一个 Unity 项目，我在其中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类似 filezilla 的软件吗？

我遇到了 webRequest class但是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。我从位于 onGUI() 函数内的 FTPupload 函数中得到一个错误。

请您参考如下方法:

您走在正确的轨道上。我想这就是您正在寻找的用法: https://github.com/mminer/ftpuploader-unity/blob/master/Editor/Uploader.cs

向下滚动到上传方法；我用了很多次，效果很好。
