python - 调试 Python Instagram API 客户端 - 'NoneType' 没有 len()

Question

这里是 Python 新手，所以请耐心等待...

我正在尝试使用 Python client for Instagram API ，并且在将 token 传递到 InstagramAPI 构造函数时输入有效的访问 token 和用户 ID(是的，我正在运行插入了访问 token 和用户 ID 的代码，但没有发布问题):

from instagram.client import InstagramAPI

access_token = "YOUR_ACCESS_TOKEN"
api = InstagramAPI(access_token=access_token)
recent_media, next_ = api.user_recent_media(user_id="userid", count=10)
for media in recent_media:
   print media.caption.text

但在终端中我不断收到此错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/instagram/bind.py", line 196, in _call

    if len(key) > blocksize:

关于如何调试此错误有什么建议吗？具体来说，这个错误的可能来源是什么？

TypeError: object of type 'NoneType' has no len()

您遇到了一个错误，因为 github 上的文档(自述文件)不是最新的。仔细阅读此问题以找到您的解决方案

Missing argument for InstagramAPI object instance

OAuth Signing is broken in 1.3.1

你的代码应该是:

from instagram.client import InstagramAPI 

access_token = "YOUR_ACCESS_TOKEN" 
client_secret = "YOUR_CLIENT_SECRET"
api = InstagramAPI(client_secret=client_secret, access_token=access_token)
