KeyError: 'data' with Python Instagram API client

问题

I'm using this client python-instagram with Python 3.4.3 on MacOS.

Here are my steps:

Registered a new client on instagram, received client_id and client_secret
Pip install python-instagram
Copy sample_app.py to my mac

I followed the instructions on Sample app, I successfully authorized my app via instagram and tried this list of examples, but none of them worked. After my click the <h2> header and counter of API requests changes and I see Remaining API Calls = 486/500.

If I try to get User Recent Media an exception KeyError: 'data' shows in my terminal. If I delete try - except construction, leaving block in try, when I'll see 'Error: 500 Internal Server Error'.

Here is the traceback:

KeyError: 'data'

All the code I used is from the sample of the official python API client by Instagram.

There is an open Github issue for this bug, a fix was sent, but it's not merged yet.

Add the one line fix to models.py on your installed package.

Open with sudo:

sudo vi /Library/Python/2.7/site-packages/instagram/models.py  # Use relevant python version

On line 99, add this:

if "data" in entry["comments"]:

Correct indentation on next two lines:

       for comment in entry['comments']['data']: 
           new_media.comments.append(Comment.object_from_dictionary(comment))

回答2:

It appears that there is a bug in models.py. If you comment out line 99 and 100 in that file, the "sample app" will work, or at least appears to work. Obviously, this is not a "real" fix but it does show that it is not a problem with the sample Python program, or Instagram.

    Line 99  #  for comment in entry['comments']['data']:
    Line 100 #      new_media.comments.append(Comment.object_from_dictionary(comment))

+1 for answer from @forge

For docker users (as asked in a comment), fork the python-instagram repo, edit, and then pip install via github.

Or just use someone else's fork with the following line in your Dockerfile:

pip install git+https://github.com/zgazak/python-instagram

pythoninstagram-api docker

回答4:

This is not really an answer just a quick workaround based on the answer by @forge when you are working in environments like docker or an environment that doesn't have a readable terminal.

sed -i '99,100 s/^/#/' /usr/local/lib/python3.5/site-packages/instagram/models.py
