如何用Android Studio通过YouTube Data V3 API上传视频

1. 添加依赖 #

在Maven项目中引入Google客户端库依赖：

<dependencies>
    <dependency>
        <groupId>com.google.apis</groupId>
        <artifactId>google-api-services-youtube</artifactId>
        <version>v3-rev20240215-2.0.0</version>
    </dependency>
    <dependency>
        <groupId>com.google.oauth-client</groupId>
        <artifactId>google-oauth-client-jetty</artifactId>
        <version>1.40.1</version>
    </dependency>
    <dependency>
        <groupId>com.google.http-client</groupId>
        <artifactId>google-http-client-gson</artifactId>
        <version>1.43.3</version>
    </dependency>
</dependencies>

2. 核心上传代码 #

以下是完整的视频上传实现，包含OAuth授权和视频元数据配置：

import com.google.api.client.auth.oauth2.Credential;
import com.google.api.client.extensions.java6.auth.oauth2.AuthorizationCodeInstalledApp;
import com.google.api.client.extensions.jetty.auth.oauth2.LocalServerReceiver;
import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow;
import com.google.api.client.googleapis.auth.oauth2.GoogleClientSecrets;
import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport;
import com.google.api.client.http.FileContent;
import com.google.api.client.json.gson.GsonFactory;
import com.google.api.services.youtube.YouTube;
import com.google.api.services.youtube.model.Video;
import com.google.api.services.youtube.model.VideoSnippet;
import com.google.api.services.youtube.model.VideoStatus;

import java.io.IOException;
import java.io.InputStreamReader;
import java.security.GeneralSecurityException;
import java.util.Arrays;
import java.util.List;

public class YouTubeUploader {
    // 定义API所需权限
    private static final List<String> SCOPES = Arrays.asList("https://www.googleapis.com/auth/youtube.upload");
    private static final String APPLICATION_NAME = "你的应用名称";
    // 客户端密钥文件路径（放在项目resources目录下）
    private static final String CLIENT_SECRETS_PATH = "/client_secrets.json";

    public static void main(String[] args) throws GeneralSecurityException, IOException {
        // 初始化HTTP传输和JSON工厂
        var httpTransport = GoogleNetHttpTransport.newTrustedTransport();
        var jsonFactory = GsonFactory.getDefaultInstance();

        // 加载客户端密钥
        var clientSecrets = GoogleClientSecrets.load(jsonFactory,
                new InputStreamReader(YouTubeUploader.class.getResourceAsStream(CLIENT_SECRETS_PATH)));

        // 构建授权流程
        var flow = new GoogleAuthorizationCodeFlow.Builder(
                httpTransport, jsonFactory, clientSecrets, SCOPES)
                .setAccessType("offline")
                .setApprovalPrompt("force")
                .build();

        // 启动本地服务器接收授权回调
        var receiver = new LocalServerReceiver.Builder().setPort(8080).build();
        Credential credential = new AuthorizationCodeInstalledApp(flow, receiver).authorize("user");

        // 初始化YouTube服务实例
        var youtubeService = new YouTube.Builder(httpTransport, jsonFactory, credential)
                .setApplicationName(APPLICATION_NAME)
                .build();

        // 配置视频元数据
        var videoSnippet = new VideoSnippet();
        videoSnippet.setTitle("测试上传视频标题");
        videoSnippet.setDescription("通过YouTube Data V3 API上传的测试视频");
        videoSnippet.setTags(Arrays.asList("测试", "API上传"));
        videoSnippet.setCategoryId("22"); // 分类ID，22对应People & Blogs，可按需修改

        // 设置视频隐私状态（public/private/unlisted）
        var videoStatus = new VideoStatus();
        videoStatus.setPrivacyStatus("unlisted");

        // 组装视频对象
        var video = new Video();
        video.setSnippet(videoSnippet);
        video.setStatus(videoStatus);

        // 指定待上传的视频文件
        var videoFile = new java.io.File("/path/to/your/video.mp4");
        var mediaContent = new FileContent("video/*", videoFile);

        // 执行上传请求
        var insertRequest = youtubeService.videos().insert(Arrays.asList("snippet", "status"), video, mediaContent);
        insertRequest.setNotifySubscribers(true); // 是否通知订阅者

        // 获取上传结果
        var uploadedVideo = insertRequest.execute();
        System.out.println("视频上传完成，视频ID：" + uploadedVideo.getId());
        System.out.println("视频链接：https://www.youtube.com/watch?v=" + uploadedVideo.getId());
    }
}

3. 关键注意事项 #

• 客户端密钥配置：将Google Cloud Console生成的对应Java应用类型的client id和secret保存为client_secrets.json，放在项目resources目录下；若适配安卓端，需调整为安卓授权流程。
• 权限申请：必须启用https://www.googleapis.com/auth/youtube.upload权限，否则无法完成上传操作。
• 视频格式要求：仅支持YouTube兼容格式（如MP4），文件大小不超过128GB、时长不超过12小时。
• OAuth授权流程：首次运行会自动打开浏览器引导授权，授权后生成凭证文件，后续运行无需重复授权。
