來自Unity的WebRequest項目

Question

我有一個Unity項目，我在其中存儲數據到本地文件夾。我想使用ftp客戶端將這些數據發送到服務器。我如何在Unity中執行此操作？這是否是一種方式？任何圖書館或像我可以執行的filezilla軟件？

我碰到webRequest class但是我不確定如何使用它。我遇到了答案中的建議代碼，但我不確定我將如何使用它。我在onGUI()函數中的FTPupload函數中發生錯誤。

你在正確的軌道上。我想這是你正在尋找的用法： https://github.com/mminer/ftpuploader-unity/blob/master/Editor/Uploader.cs

向下滾動到Upload方法;我用了很多次，效果很好。

[編輯] 這裏的aboves代碼樣本比可以直接在統一項目中使用：
