Python 3.x 将文件发送到dropbox时出错

大家好， 我正试图用以下代码向dropbox发送文件：

import dropbox

f = open('test.txt')

dbx = dropbox.Dropbox('ACCESS TOKEN')

dbx.files_upload(f, '/uploaded.csv')

f.close()

Traceback (most recent call last):
  File "C:\Users\Erim\Desktop\aa.py", line 7, in <module>
    dbx.files_upload(f, '/uploaded.csv')
  File "C:\Users\Erim\AppData\Local\Programs\Python\Python35-32\lib\site-packages\dropbox\base.py", line 1267, in files_upload
    f,
  File "C:\Users\Erim\AppData\Local\Programs\Python\Python35-32\lib\site-packages\dropbox\dropbox.py", line 234, in request
    timeout=timeout)
  File "C:\Users\Erim\AppData\Local\Programs\Python\Python35-32\lib\site-packages\dropbox\dropbox.py", line 325, in request_json_string_with_retry
    timeout=timeout)
  File "C:\Users\Erim\AppData\Local\Programs\Python\Python35-32\lib\site-packages\dropbox\dropbox.py", line 369, in request_json_string
    type(request_binary))
TypeError: expected request_binary as binary type, got <class '_io.TextIOWrapper'>

但是，我收到了以下错误消息：

import dropbox

f = open('test.txt')

dbx = dropbox.Dropbox('ACCESS TOKEN')

dbx.files_upload(f, '/uploaded.csv')

f.close()

Traceback (most recent call last):

有人知道我做错了什么吗？

看起来你没有正确验证你的应用程序

# Include the Dropbox SDK
import dropbox

# Get your app key and secret from the Dropbox developer website
app_key = 'INSERT_APP_KEY'
app_secret = 'INSERT_APP_SECRET'

flow = dropbox.client.DropboxOAuth2FlowNoRedirect(app_key, app_secret)
