php - 如何使用PHP中的YouTube API在特定 channel 上载视频？

Question

我想为用户提供无需身份验证即可在我的 channel 上上传视频的功能(如果需要)。可能吗 ？

请帮我 。

谢谢

是的，有可能

您将需要适用于PHP的Google API客户端库。

您还需要在以下位置创建一个项目
https://console.developers.google.com/并获取凭据(即
客户 secret 和客户ID)。

最后，您需要为特定 channel 生成访问 token 。
请看这个链接
(https://youtube-eng.googleblog.com/2013/06/google-page-identities-and-youtube-api_24.html)
生成访问 token 。

准备好所有这些东西之后，就可以使用现成的
Google API客户端库中提供的示例代码供PHP上传
YouTube上的视频。

注意:这不是详细过程，无法详细说明堆栈溢出的所有过程。但是，一旦您接近解决方案，就可以重新发布或发表评论以寻求进一步的帮助。

这是在YouTube上上传视频的示例代码。希望对您有帮助

            // with ->execute(); instead of making the API call immediately.
            $client->setDefer(true);

            // Create a request for the API's videos.insert method to create and upload the video.

            fclose($handle);
