Drive API-使用Python保存文件ID

问题描述

我正在尝试使用Google Drive API快速入门来使用Python保存所有文件ID。

我想将文件ID保存在txt文档中

这是我的代码

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/drive.Metadata.readonly']



def main():
    """Shows basic usage of the Drive v3 API.
    Prints the names and ids of the first 10 files 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(
                '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('drive','v3',credentials=creds)

    # Call the Drive v3 API
    results = service.files().list(
        pageSize=10,fields="nextPagetoken,files(id,name)").execute()
    items = results.get('files',[])

    if not items:
        print('No files found.')
    else:
        print('Files:')
        for item in items:
            print(u'{0} ({1})'.format(item['name'],item['id']))
        archivo = open("Prueba.txt","a")
        archivo.write(item['id'])
        archivo.close()
    
           
            

if __name__ == '__main__':
    main()
    

我想保存所有文件ID，但是我的程序无法正常运行，只能保存最后一个文件ID

发生了什么事？

解决方法

从（对于项目中的项目：）删除到（archivo.close（））

然后复制并粘贴：

 for item in items:
            print(u'{0} ({1})'.format(item['name'],item['id']))
            archivo = open("Prueba.txt","a")
            archivo.write(item['id'])
            archivo.close()

这应该有效
