Question

我是Youtube数据API的新手，我试图在我的计算机上开发一个独立的Java应用程序来解析Youtube视频中的一些评论。 CommentThreads-list的示例代码在https://developers.google.com/youtube/v3/docs/commentThreads/list

上提供

// Sample Java code for user authorization

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.googleapis.json.GoogleJsonResponseException;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.util.store.FileDataStoreFactory;

import com.google.api.services.youtube.YouTubeScopes;
import com.google.api.services.youtube.model.*;
import com.google.api.services.youtube.YouTube;

import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.Arrays;
import java.util.Collection;
import java.util.HashMap;
import java.util.List;


public class ApiExample {

/** Application name. */
private static final String APPLICATION_NAME = "API Sample";

/** Directory to store user credentials for this application. */
private static final java.io.File DATA_STORE_DIR = new java.io.File(
System.getProperty("user.home"), ".credentials/java-youtube-api-tests");

/** Global instance of the {@link FileDataStoreFactory}. */
private static FileDataStoreFactory DATA_STORE_FACTORY;

/** Global instance of the JSON factory. */
private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();

/** Global instance of the HTTP transport. */
private static HttpTransport HTTP_TRANSPORT;

/** Global instance of the scopes required by this quickstart.
 *
 * If modifying these scopes, delete your previously saved credentials
 * at ~/.credentials/drive-java-quickstart
 */
private static final Collection<String> SCOPES = Arrays.asList("YouTubeScopes.https://www.googleapis.com/auth/youtube.force-ssl YouTubeScopes.https://www.googleapis.com/auth/youtubepartner");

static {
    try {
        HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
        DATA_STORE_FACTORY = new FileDataStoreFactory(DATA_STORE_DIR);
    } catch (Throwable t) {
        t.printStackTrace();
        System.exit(1);
    }
}

/**
 * Creates an authorized Credential object.
 * @return an authorized Credential object.
 * @throws IOException
 */
public static Credential authorize() throws IOException {
    // Load client secrets.
    InputStream in = ApiExample.class.getResourceAsStream("/client_secret.json");
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader( in ));

    // Build flow and trigger user authorization request.
    GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
    HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
        .setDataStoreFactory(DATA_STORE_FACTORY)
        .setAccessType("offline")
        .build();
    Credential credential = new AuthorizationCodeInstalledApp(
    flow, new LocalServerReceiver()).authorize("user");
    System.out.println(
        "Credentials saved to " + DATA_STORE_DIR.getAbsolutePath());
    return credential;
}

/**
 * Build and return an authorized API client service, such as a YouTube
 * Data API client service.
 * @return an authorized API client service
 * @throws IOException
 */
public static YouTube getYouTubeService() throws IOException {
    Credential credential = authorize();
    return new YouTube.Builder(
    HTTP_TRANSPORT, JSON_FACTORY, credential)
        .setApplicationName(APPLICATION_NAME)
        .build();
}

public static void main(String[] args) throws IOException {

    YouTube youtube = getYouTubeService();

    try {
        HashMap<String, String> parameters = new HashMap<>();
        parameters.put("part", "snippet,replies");
        parameters.put("videoId", "m4Jtj2lCMAA");

        YouTube.CommentThreads.List commentThreadsListByVideoIdRequest = youtube.commentThreads().list(parameters.get("part").toString());
        if (parameters.containsKey("videoId") && parameters.get("videoId") != "") {
            commentThreadsListByVideoIdRequest.setVideoId(parameters.get("videoId").toString());
        }

        CommentThreadListResponse response = commentThreadsListByVideoIdRequest.execute();
        System.out.println(response);


    } catch (GoogleJsonResponseException e) {
        e.printStackTrace();
        System.err.println("There was a service error: " + e.getDetails().getCode() + " : " + e.getDetails().getMessage());
    } catch (Throwable t) {
        t.printStackTrace();
    }
}
}

After I run the above sample code in eclipse, the browser opens but it shows "Error: invalid_scope". I've attached an image to show this.

至于我的OAuth客户端ID，我在youtube开发者控制台上创建了一个凭据，然后我选择了＆＃34;其他＆＃34;作为我的项目的应用程序类型。

我也尝试了＃34; Web应用程序＆＃34;我为授权重定向URI分配了我的localhost http：// localhost / Callback。这也没有用。

您应该在代码中指定正确的范围，请检查这些更改。

private static final Collection<String> SCOPES = Arrays.asList("https://www.googleapis.com/auth/youtube.force-ssl", 
"https://www.googleapis.com/auth/youtubepartner");

另外，我认为了解现有产品以检测您需要更多产品会更好。所有youtube范围都开始：https://www.googleapis.com/auth/（在范围示例中将忽略/跳过此部分以减少重复）

YouTube Analytics API v1：

auth/youtube
youtube.readonly
youtubepartner
yt-analytics-monetary.readonly
yt-analytics.readonly

YouTube Data API v3：

youtube
youtube.force-ssl
youtube.readonly
youtube.upload
youtubepartner
youtubepartner-channel-audit

YouTube Reporting API v1

yt-analytics-monetary.readonly
yt-analytics.readonly

Youtube API CommentThreads的范围无效 - java
