Boxsdk JWTAuth keeps giving me this error: 'NoneType' object has no attribute 'encode'
Boxsdk JWTAuth keeps giving me this error: 'NoneType' object has no attribute 'encode'
我正在尝试在 python 中编写一个小脚本来连接到 BOX，但它一直给我这个错误：'NoneType' object has no attribute 'encode'
一开始我以为是我对Passphrase进行编码造成的，但好像不是这样。当我尝试使用 access_token = auth.authenticate_instance() 进行身份验证时，脚本失败。如果我 运行 脚本没有它似乎工作。可能是什么原因造成的？
在此先感谢您提供的任何帮助。
这是我的：

我根本不知道你用的是什么 API，但是根据查看代码的一些想法：
自下而上处理堆栈跟踪，您有：

password_encrypted = self.encrypt(password.encode('utf-8'), assoc)
AttributeError: 'NoneType' object has no attribute 'encode'
那个代码在https://github.com/jaraco/keyrings.alt/blob/master/keyrings/alt/file_base.py，而密码（我们知道是None）是最后传入set_password函数的参数。调用自：
File "/home/Marketscale/.virtualenvs/myvirtualenv/lib/python3.5/site-packages/keyring/core.py", line 48, in set_password
_keyring_backend.set_password(service_name, username, password)
该代码位于 https://github.com/jaraco/keyring/blob/master/keyring/core.py，密码也是 set_password 函数的最后一个参数。接下来，我们有：
File "/home/Marketscale/Tests/JWTTest.py", line 22, in store_tokens
keyring.set_password('Box_Refresh', 'mybox@box.com', refresh_token)
..这是你的代码，所以 refresh_token 一定是 None。这意味着您的 store_tokens 必须使用 None 的 refresh_token 调用。下一篇：

self._store_tokens_callback(access_token, refresh_token)
这是在 https://github.com/box/box-python-sdk/blob/master/boxsdk/auth/oauth2.py，再次意味着调用 _store_tokens 时 refresh_token 设置为 None。继续...
File "/home/Marketscale/.virtualenvs/myvirtualenv/lib/python3.5/site-packages/boxsdk/auth/oauth2.py", line 298, in send_token_request

代码与上一个页面相同，但现在更有趣了：

headers = {'content-type': 'application/x-www-form-urlencoded'}

self._store_tokens(access_token, refresh_token)
return self._access_token, self._refresh_token
所以我们知道调用 self._store_tokens 时 refresh_token 设置为 None，这意味着 expect_refresh_token 一定是 False，否则 BoxOAuthException 会被提出。事实上，如果我们查看堆栈跟踪中的下一行，我们可以看到：

return self.send_token_request(data, access_token=None, expect_refresh_token=False)[0]
这向我表明，当您使用 JWT Auth 时，您不应该期待刷新令牌。并且考虑到当您将 None 作为密码传递给它时密钥环的文件后端会爆炸，听起来您需要以不同的方式处理 None 情况。因此，我建议更改您提供的 store_tokens 函数，以便它在 None 时忽略刷新令牌，即：
def store_tokens(access_token, refresh_token):
"""Callback function when Box SDK refreshes tokens"""
# Use keyring to store the tokens
keyring.set_password('Box_Auth', 'mybox@box.com', access_token)
if refresh_token is not None:
keyring.set_password('Box_Refresh', 'mybox@box.com', refresh_token)
...或者这样它将 None 转换成密钥环文件后端可以优雅处理的东西——也许一个空字符串就可以做到这一点：
def store_tokens(access_token, refresh_token):
"""Callback function when Box SDK refreshes tokens"""
# Use keyring to store the tokens
keyring.set_password('Box_Auth', 'mybox@box.com', access_token)
if refresh_token is None:
refresh_token = ""
keyring.set_password('Box_Refresh', 'mybox@box.com', refresh_token)
