我正在尝试将谷歌教室集成到我的 java 项目中使用 OAuth 2.0 进行服务器到服务器身份验证，此处给出了示例官方 Google 教室集成文档使用OAuth 同意屏幕身份验证，我更改了服务器到服务器身份验证的代码，并进行了一些更改

目前进展：

  • 创建了一个谷歌应用

  • 从仪表板启用 Google 课堂 API。

  • 为服务器到服务器身份验证创建服务帐户密钥 (.p12)（后来在代码中与应用程序名称一起使用）

    public class Quickstart2 {
    private static final String APPLICATION_NAME ="MY_APP_NAME";
    private static final JsonFactory JSON_FACTORY =
        JacksonFactory.getDefaultInstance();
    private static HttpTransport httpTransport;

    /** Global instance of the HTTP transport. */
    private static HttpTransport HTTP_TRANSPORT;
    private static final String SERVICE_ACCOUNT_EMAIL = "ID_CREADED_ON_GOOGLE_APP";
    /** Global instance of the scopes required by this quickstart.
     *
     * If modifying these scopes, delete your previously saved credentials
     * at ~/.credentials/classroom.googleapis.com-java-quickstart
     */
    private static final List<String> SCOPES =
        Arrays.asList(ClassroomScopes.CLASSROOM_COURSEWORK_ME);

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

    /**
     * Creates an authorized Credential object.
     * @return an authorized Credential object.
     * @throws IOException
     * @throws GeneralSecurityException 
     */
    public static Credential authorize() throws IOException, GeneralSecurityException {  
        /* Added this code in given sample code for Server-to-server authentication*/


      httpTransport = GoogleNetHttpTransport.newTrustedTransport();
      GoogleCredential credential = new GoogleCredential.Builder().setTransport(httpTransport)
          .setJsonFactory(JSON_FACTORY)
          .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
          .setServiceAccountScopes(SCOPES)
          .setServiceAccountPrivateKeyFromP12File(new File("BULB-1cb9e145138b.p12"))
           .setServiceAccountUser("bulb-88@bulb-173512.iam.gserviceaccount.com") 
          .build();
      return credential;
    }

    /**
     * Build and return an authorized Classroom client service.
     * @return an authorized Classroom client service
     * @throws IOException
     * @throws GeneralSecurityException 
     */
    public static com.google.api.services.classroom.Classroom
            getClassroomService() throws IOException, GeneralSecurityException {
        Credential credential = authorize();
        System.out.println("token   "+credential.getAccessToken());
        return new com.google.api.services.classroom.Classroom.Builder(
                HTTP_TRANSPORT, JSON_FACTORY, credential)
                .setApplicationName(APPLICATION_NAME)
                .build();
    }

    public static void main(String[] args) throws IOException, GeneralSecurityException {
        // Build a new authorized API client service.
        com.google.api.services.classroom.Classroom service =
            getClassroomService();

        Course course = new Course()
        .setName("10th Grade Biology")
        .setSection("Period 2")
        .setDescriptionHeading("Welcome to 10th Grade Biology")
        .setDescription("test descriptioon")
        .setRoom("301")
        .setOwnerId("me")
        .setCourseState("PROVISIONED");
         course = service.courses().create(course).execute(); /* here I am getting the exception */


       //  List the first 10 courses that the user has access to.

        ListCoursesResponse response = service.courses().list()
            .setPageSize(10)
            .execute();
        List<Course> courses = response.getCourses();
        System.out.println(courses);
        if (courses == null || courses.size() == 0) {
            System.out.println("No courses found.");
        } else {
            System.out.println("Courses:");
            for (Course course1 : courses) {
                System.out.printf("%s\n", course1.getName());
            }
        }
    }

    }

我相信身份验证没有任何问题，因为每当我运行这段代码时，都会在我的应用程序“ https://console.developers.google.com/apis/dashboard ”的仪表板中获得一个条目

这是我在仪表板上得到的图像

我是谷歌教室的新手，很长时间以来我一直在尝试整合这个到目前为止没有成功，需要帮助。

还有一件事它说必须拥有一个G套件帐户（我不知道它在哪里使用，但我还没有创建G套件帐户，这就是我得到例外的原因）

如果我想在上面的 senerio 上添加更多详细信息，请告诉我。

提前致谢

Gsuite 帐户可在此处找到。课堂 API 范围可在使用 OAuth 2.0 授权请求中找到
