python程序将jpg文件插入谷歌幻灯片演示文稿答案

【问题标题】：python program to insert jpg files into a google slides presentationpython程序将jpg文件插入谷歌幻灯片演示文稿

【问题描述】：

下一次尝试：假设我有一个包含 jpg 图像文件的目录，并且最早的图像（时间戳）应该是幻灯片 #1，而最新的图像幻灯片 #N 要插入到谷歌幻灯片演示文稿中。我正在使用the API Windows 10 上的安装显然没问题。之前报告的问题已经修复，感谢帮助我的人。

接下来，这段 python 代码是为了检查 API 是否适合我：（与我第一次创建这篇文章相比修改了）

请注意，我已将代码包含在 https://github.com/googleworkspace/python-samples/blob/master/slides/snippets/slides_snippets.py 如下：

import library_JP

现在有一个新问题：

【问题讨论】：

从你的报错信息中，发现你报错信息的原因是https://www.googleapis.com/auth/presentations.readonly的范围。当你想使用presentations().create()的方法时，需要使用https://www.googleapis.com/auth/presentations。但我无法理解您的脚本与Assume that I have a directory with jpg image files, and the oldest image (time stamp) should be slide #1, and the newest image slide #N to be inserted in a google slides presentation. 之间的关系。我可以问你这个问题的目标吗？
感谢您的建议，我可以解决问题。然后我发布了导致下一个异常的代码的修改版本
感谢您的回复。我很高兴你的问题得到了解决。当您的问题解决后，您可以将其发布为答案吗？这样，它对遇到相同问题的其他用户很有用。
这里的问题似乎是请求中缺少 field 参数。但是，我并不是你想要达到的目标？

【解决方案1】：

此代码有效；删除 token.pickle 并具有以下条目很重要：

SCOPES = ['https://www.googleapis.com/auth/presentations']

而不是

SCOPES = ['https://www.googleapis.com/auth/presentations.readonly'] ```

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/presentations.readonly']
SCOPES = ['https://www.googleapis.com/auth/presentations']

# The ID of a sample presentation.
PRESENTATION_ID = '1EAYk18WDjIG-zp_0vLm3CsfQh_i8eXc67Jo2O9C6Vuc'

def main():
    """Shows basic usage of the Slides API.
    Prints the number of slides and elments in a sample presentation.
    """
    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(
                '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('slides', 'v1', credentials=creds)

    # Call the Slides API
    title = 'JP_february13-2021 '
    body = {
    'title': title
    }
#    presentation = slides_service.presentations() \
    presentation = service.presentations() \
    .create(body=body).execute()
    print('Created presentation with ID: {0}'.format(
    presentation.get('presentationId')))

#    print('The presentation contains {} slides:'.format(len(slides)))
#    for i, slide in enumerate(slides):
#        print('- Slide #{} contains {} elements.'.format(
#            i + 1, len(slide.get('pageElements'))))


if __name__ == '__main__':
    main()

但是，我尝试在演示文稿中包含图像的下一个版本确实不工作。
