Question

我正试图通过直接将图像文件写入DropBox来减少我的SD卡上的读/写。我将图像捕获到流中，但我不知道如何将其写入Dropbox。这是覆盆子pi。

dbx = dropbox.Dropbox('token')
stream = io.BytesIO()

with picamera.PiCamera() as camera:
    camera.resolution = (1280,960)
    camera.capture(stream,format='jpeg')
stream.seek(0)
im = Image.open(stream)
dbx.files_upload(im,"/test.jpg",mute=True)

我收到以下错误，但不确定它的含义或如何修复它。

Traceback (most recent call last):
  File "./camera.py", line 25, in <module>
    dbx.files_upload(im,"/test.jpg",mute=True)

  File "/usr/local/lib/python2.7/dist-packages/dropbox/base.py", line 1225, in files_upload

    type(request_binary))

TypeError: expected request_binary as binary type, got <type 'instance'>

如何直接将图像写入Dropbox？
