从GoogleClassroomApi[403]Python检索类工作

我正试图从谷歌课堂API中检索每门课程的课堂作业。我已经成功地获得了所有课程，但我仍停留在课程作业上：

这是我正在使用的代码：

from __future__ import print_function
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

# If modifying these scopes, delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/classroom.coursework.students.readonly']


def main():
    """Shows basic usage of the Classroom API.
    Prints the names of the first 10 courses the user has access to.
    """
    creds = None
    # The file token.pickle stores the user's access and refresh tokens, and is
    # created automatically when the authorization flow completes for the first
    # time.
    if os.path.exists('token.pickle'):
        with open('token.pickle', 'rb') as token:
            creds = pickle.load(token)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                r"\test\credentials.json", SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.pickle', 'wb') as token:
            pickle.dump(creds, token)

    service = build('classroom', 'v1', credentials=creds)

    # Call the Classroom API
    course_work_results = service.courses().courseWork().list(courseId="167997334462").execute()
    
    [...]

if __name__ == '__main__':
    main()

我已使用管理员帐户生成凭据；我还尝试了几种不同的作用域，但都是相同的错误

你们能帮帮我吗

我正在使用Python 3.9

谢谢， 亚历山大

因为您正在使用范围

https://www.googleapis.com/auth/classroom.coursework.students.readonly

我想你是个学生

学生仅允许在其被接受为课程参与者的情况下访问课程的课程作业

尝试检索其他课程的课程作业将导致403错误

如果你不是学生，而是谷歌工作区域的管理员，你应该使用更广泛的范围，例如。

https://www.googleapis.com/auth/classroom.coursework.me.readonly

请注意，在更改源代码中的作用域后，您需要删除令牌文件以触发新的身份验证流
