我正在尝试使用Simple Access API（API密钥）在我的YouTube帐户中上传视频。

我得到了这个例外。

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

有什么问题？

使用youtube-API的简单访问API（API密钥）的文档很差。 有谁可以帮助我？

我的简单访问API：

Simple API Access

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

Key for server apps (with IP locking)
API key:   AIzaSxxxxxxxxxxxxxxxxxxxxxxx-bVE8jRlzXY
IPs:   Any IP allowed

答案 0 :(得分：0)

正如您在发布的代码段中所看到的，当您不需要访问用户数据时，简单访问API密钥旨在识别您的项目（即为了配额）。将视频上传到帐户是一种访问用户数据的形式，因此您需要使用oauth2，请求范围“https://www.googleapis.com/auth/youtube.upload”，然后使用访问令牌执行上传。

一旦你运行了oauth2流并且你的用户授予了对作用域的访问权限，你的代码的其余部分看起来似乎是正确的（但我不是Java专家所以不要让我这么做！）
