如何以编程方式将 Youtube 上的视频上传到 Android 上的特定 youtube 帐户

Question

这是我的用例： 我希望用户能够将视频内容从他们的设备直接上传到我的 youtube 或专用的 youtube 帐户，而无需离开我的应用程序。首先，这可能吗？请我欣赏代码示例。谢谢

This 展示了如何使用 HTTP 请求上传视频。

code snippets 在 java 中也可用（和 kotlin 非常相似）。

要查看如何上传视频，请转到https://developers.google.com/youtube/v3/code_samples/code_snippets，在Resource 下选择Videos，在方法下选择insert。

如果你然后点击Show code并选择顶部的JAVA，你会得到这个示例代码：

        // Define the Video object, which will be uploaded as the request body.
        Video video = new Video();
        
        // Add the snippet object property to the Video object.
        VideoSnippet snippet = new VideoSnippet();
        snippet.setCategoryId("22");
        snippet.setDescription("Description of uploaded video.");
        snippet.setTitle("Test video upload.");
        video.setSnippet(snippet);
        
        // Add the status object property to the Video object.
        VideoStatus status = new VideoStatus();
        status.setPrivacyStatus("private");
        video.setStatus(status);

        // TODO: For this request to work, you must replace "YOUR_FILE"
        //       with a pointer to the actual file you are uploading.
        //       The maximum file size for this operation is 137438953472.
        File mediaFile = new File("YOUR_FILE");
        InputStreamContent mediaContent =
            new InputStreamContent("application/octet-stream",
                new BufferedInputStream(new FileInputStream(mediaFile)));
        mediaContent.setLength(mediaFile.length());

        // Define and execute the API request
        YouTube.Videos.Insert request = youtubeService.videos()
            .insert("snippet,status", video, mediaContent);
        Video response = request.setKey(DEVELOPER_KEY).execute();
        System.out.println(response);
    }
}

你也可以看看另一个example java code for uploading a video to YouTube on GitHub。

请注意，您需要对此进行一些更改：

在 android 下，您没有 main。您将需要 (1) 将该代码放在您需要的任何位置，并且您可能希望 ro (2) 异步执行。

在使用 kotlin 时，您还 (3) 需要相应地修改语法。
