錯誤「401未經授權」使用Simple Access API（API密鑰）在我的YouTube帳戶中上傳視頻

Question

我試圖使用Simple Access API（API Key）在我的YouTube帳戶中上傳視頻。

我得到這個異常。

You chose src/resources/video.avi to upload. 
Initiation Started

出了什麼問題？

使用Simple API（API Key）和youtube-API的文檔非常差。 任何人都可以幫助我嗎？

我的簡單訪問API：

Simple API Access 

Use API keys to identify your project when you do not need to access user data.

正如你可以在您發佈的片段看到，簡單的訪問API密鑰的目的是確定項目（即配額的緣故），當你做不需要訪問用戶數據。將視頻上傳到帳戶是一種訪問用戶數據的形式，因此您需要使用oauth2，請求範圍'https://www.googleapis.com/auth/youtube.upload'，然後使用訪問令牌執行上傳。

一旦你的OAuth2流程運行和您的用戶訪問權限授予的範圍，似乎你的代碼的其餘部分看起來正確的（但我不是一個Java專家，所以不要抱着我的！）
