python - pydrive上传文件400 "Bad Request"

Question

我正在使用 PyDrive 将文件从一个 GDrive 帐户上传到另一个帐户。我可以很好地下载该文件，但是当我上传它时，我得到了 400。

pydrive.files.ApiRequestError: <HttpError 400 when requesting https://www.googleapis.com/upload/drive/v2/files?alt=json&uploadType=resumable returned "Bad Request">

这是ListFolder代码:

def ListFolder(parent, drive1, drive2):
    filecount = 0 
    filelist=[]
    file_list = drive1.ListFile({'q': "'%s' in parents and trashed=false" % parent}).GetList()
    for f in file_list:
        filecount +=1
        print("Still working %s" % filecount)
        if f['mimeType']!='application/vnd.google-apps.folder': # if regular file
            print("I've found a file - passing %s to download" % f['title'])
            download_file(drive1, f, drive2) # Download the file

这里是下载文件代码:

def download_file(drive1, f, drive2):
    """This function will download a file from the source drive1 to the local hard drive, just before uploading it to the destination drive- i.e. drive2"""
    dirpath = tempfile.mkdtemp()
    print ("Downloading a file %s" % f['title'])
    filesource = drive1.CreateFile({'id': f['id']})
    filesource.GetContentFile(f['title'], f['mimeType'])
    upload_file(drive2, f)
    os.remove(f['title'])

drive2 是一个 GoogleDrive 实例(已通过身份验证)。 f 是 file_list 中的一项，但不是文件夹。

def upload_file(drive2, f):
    #Will copy files over until it detects a directory
    """"This function accepts the destination drive, filetitle (which has previously been downloaded from download_file function) and the file mimetype. This function uploads the local file to the destination drive"""
    filename = f['title']
    print("file title: %s" % f['title']) #filetitle)
    file = drive2.CreateFile()
    file.SetContentFile(f['title'])
    file.Upload()

我尝试使用字符串上传文件，但仍然得到相同的结果。我还应该寻找什么？

这是来自 export files guide 的下载片段:

file_id = '1ZdR3L3qP4Bkq8noWLJHSr_iBau0DNT4Kli4SxNc2YEo'
request = drive_service.files().export_media(fileId=file_id,
                                             mimeType='application/vnd.google-apps.document')
fh = io.BytesIO()
downloader = MediaIoBaseDownload(fh, request)
done = False
while done is False:
    status, done = downloader.next_chunk()
    print "Download %d%%." % int(status.progress() * 100)
