如何处理驱动器 api 的最大导出限制大小文件

Question

我正在尝试下载一些 google doc 文件，但是在它之后我需要使用导出方法转换为 microsoft word mimetype，它可以正常工作，直到它找到一个大小超过 10 mb 的文件，api 文档说这个是导出文档的限制大小，但我真的需要下载这些文件，我的脚本中的所有内容都可以正常工作，除了抛出的错误是

“此文件太大，无法导出。”。详细信息：“此文件太大，无法导出。” 那么，是否有办法避免这种限制或将文档导出到内容文件夹中

编辑：我要下载的文档不是公开的，所以我认为我需要对获取内容的请求进行身份验证

编辑 2：脚本：

SCOPES = ['https://www.googleapis.com/auth/drive.file','https://www.googleapis.com/auth/drive','https://www.googleapis.com/auth/spreadsheets']


  
def main():
    
   
    #----------------------Google drive auth-----------------------------
    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 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)

    # Call the Drive v3 API
    service = build('drive', 'v3', credentials=creds)
    sheets_service = build('sheets', 'v4', credentials=creds)

    # Call the Sheets API
    sheet = sheets_service.spreadsheets()
    
   
    
    # ID of folder that contain the wanted files
    query = "'[ID OF THE FOLDER]' in parents"

    response = service.files().list(q=query,
                                spaces='drive',
                                fields='files(id, name, parents, webViewLink,exportLinks)').execute()
    
    baseURL="https://docs.google.com/document/d/"
    for document in response['files']:
        
        
        
        downloadURL=baseURL+document["id"]+"/export?format=doc"
        

            
        r = requests.get(downloadURL)  
        
        with open('pathtosabe, 'wb') as f:

            f.write(r.content)
            
   
  
        

            
        
main()

来自您的以下replying，

好吧，这就是我不知道如何在下载文件的请求中使用访问令牌的问题，但内容显示为已损坏我尝试使用公共文档并且内容可见

我认为当您的 Google 文档未公开共享时，当访问令牌用于您的 r = requests.get(downloadURL) 脚本时，它可能会起作用。所以在这个答案中，我想使用从脚本的授权脚本中检索到的访问令牌来提议修改后的脚本。

修改脚本：

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 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)

# Call the Drive v3 API
service = build('drive', 'v3', credentials=creds)
sheets_service = build('sheets', 'v4', credentials=creds)

# Call the Sheets API
sheet = sheets_service.spreadsheets()

# ID of folder that contain the wanted files
query = "'[ID OF THE FOLDER]' in parents"
response = service.files().list(q=query,
                            spaces='drive',
                            fields='files(id, name, parents, webViewLink,exportLinks)').execute()

access_token = creds.token # Added
baseURL="https://docs.google.com/document/d/"
for document in response['files']:
    downloadURL=baseURL+document["id"]+"/export?format=doc"
    r = requests.get(downloadURL, headers={'Authorization': 'Bearer ' + access_token})  # Modified
    with open('pathtosabe', 'wb') as f:  # Modified
        f.write(r.content)

• 在您的脚本中，with open('pathtosabe, 'wb') as f: 中的'pathtosabe, 没有用单引号括起来。请注意这一点。如果要使用pathtosabe作为变量，请声明并修改为with open(pathtosabe, 'wb') as f:。
