create = service.files().create(body=file_metadata, media_body=media, **create_params) 捕获超时异常

好的，您可以使用try-except语句来捕获超时异常，如下所示：

import google.auth
from google.auth.transport.requests import Request
from googleapiclient.errors import HttpError
from googleapiclient.discovery import build

# 创建服务对象
creds = None
if creds and creds.valid:
    service = build('drive', 'v3', credentials=creds)
else:
    creds = google.auth.default(scopes=['https://www.googleapis.com/auth/drive'])
    service = build('drive', 'v3', credentials=creds)

try:
    file_metadata = {'name': 'test.txt'}
    media = MediaFileUpload('test.txt',
                            mimetype='text/plain')
    create_params = {'fields': 'id'}
    create = service.files().create(body=file_metadata,
                                    media_body=media,
                                    **create_params)
    result = None
    while result is None:
        status, result = create.next_chunk()
        if status:
            print("上传进度: {}%".format(int(status.progress() * 100)))
    print('文件已上传，文件ID：{0}'.format(result.get('id')))

except HttpError as error:
    if error.resp.status == 429:
        print('请求频率过高，请稍后再试')
    elif error.resp.status == 500 or error.resp.status == 502 or error.resp.status == 503 or error.resp.status == 504:
        print('服务器错误，请稍后再试')
    else:
        print('An error occurred: %s' % error)
except TimeoutError:
    print('请求超时，请稍后再试')

在上面的代码中，我们使用try-except语句来包含文件上传代码，并使用HttpError来捕获其他异常，使用TimeoutError来捕获超时异常。如果发生超时异常，程序将打印出“请求超时，请稍后再试”的提示。
