我正在使用下面的代码连接到sharepoint，目的是将文件上传到网站。所有的auth东西都很好，由于某种原因，我得到了一个json解码错误。这里有什么明显的吗？假设流从函数“getSharepointContext（）”开始。我已经通过了许多其他教程和问题，关于这一点，一切似乎都很好，一致。
目的是循环访问本地文件夹中的每个文件并上载到sharepoint站点/文件夹。
很明显，请求和json.loads有问题，但是如果有更多处理这样的文件的经验的人看到了一些东西，我会很感激的！

import os
from office365.runtime.auth.client_credential import ClientCredential
from office365.sharepoint.client_context import ClientContext
from logger import Logger

def getSharepointContext():
    sharepointUrl = 'https://url.sharepoint.com/site/folder/'
    clientCredentials = ClientCredential('a79f867e-3138-4qwdqwdqwdqwdqwdffe3', '_vp8Q~05OqwdqwdqwdqwdyCb_gQppjen8czP')
    ctx = ClientContext(sharepointUrl).with_credentials(clientCredentials)
    targetFolder = ctx.web.get_folder_by_server_relative_url(sharepointUrl)
    uploadFiles(targetFolder)

def uploadFiles(targetFolder):
    wd = os.getcwd()
    td = wd+'/toUpload'
    for fn in os.listdir(td):
        f = os.path.join(td, fn)
        if os.path.isfile(f):
            with open(f, 'rb') as k:
                Logger.log('Uploading: ' + f, 1, True)
                file_content = k.read()
                print(file_content)
                targetFolder.upload_file(f, file_content).execute_query()

if __name__ == "__main__":
    getSharepointContext()
