调试Python Instagram API客户端 - 'NoneType'没有len（） [英] Debugging Python Instagram API client - 'NoneType' has no len()

问题描述

我试图使用 Instagram API的API客户端，并且在将令牌传递到InstagramAPI构造函数时输入有效的访问令牌和用户ID（是的，我正在运行代码我的访问令牌和用户ID被插入，但遗漏了发布问题）：

  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）
 in recent_media：
 print media.caption.text 
  

但在终端我不断得到这个错误：

解决方案
您正面临一个错误，因为github上的doc（readme）不是最新的。仔细阅读此问题以找到您的解决方案
 
 
 
  InstagramAPI对象实例的参数缺失 
 
 
 
  OAuth签名在1.3.1中被破坏 
 
 
 
你的代码应该是：
 
 
 $ _ code从instagram.client导入InstagramAPI 
 
 access_token =YOUR_ACCESS_TOKEN
 client_secret =YOUR_CLIENT_SECRET
 api = InstagramAPI（client_secret = client_secret，access_token = access_token）
  

newbie to Python here, so bear with me...

I'm trying to use the Python client for Instagram API, and am entering a valid access token and user ID when passing the token into the InstagramAPI constructor (yes, I'm running the code with my access token and user ID inserted, but left out for posting the question):

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

but in terminal I keep getting this error:

Traceback (most recent call last):

    if len(key) > blocksize:
TypeError: object of type 'NoneType' has no len()

Any advice on how to debug this error? Specifically, what is the possible source of this error?

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

解决方案

you are facing a bug because the doc (readme) on github is not up-to-date. Read this issue carefully to find your solution

Missing argument for InstagramAPI object instance

OAuth Signing is broken in 1.3.1

your code should be:

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)
