Python 3 With Requests Trying To Use Tumblr API, I Get Error 401?

I have Python 3 and I am trying to post to Tumblr via API link to API documentation. I keep getting an error 401 despite feeling like I am doing everything correctly. There is an o

Solution 1:

Instead of doing this:

print(client_key)

What is the output of this?

print(repr(client_key))

You're using readline, which includes a newline character at the end of each line:

$ cat foo.txt
key
secret
blabla

$ python3.4
>>> f = open("foo.txt")
>>> print(repr(f.readline()))
'key\n'
>>> print(repr(f.readline()))
'secret\n'
>>> print(repr(f.readline()))
'blabla\n'

Have you tried stripping the newline character off of each line?

Edit: Updating my post based on @user2853325's comments. Your code works for me under Python 3.4, requests==2.5.2, and requests-oauthlib==0.4.2.

API.json (redacted the keys/secrets):

{
    "client_key": "XXXXXXXXXXXXXXXXXXXXdG7zXIMcDidwQ5pMHuQTbxyhNINrCE",
    "client_secret": "XXXXXXXXXXXXXXXXXXXX72A5HQO1axydP5nlOWCTQx4ECfXfyX",
    "oauth_token": "XXXXXXXXXXXXXXXXXXXX8WAnqMBWaAdnGhnc4gWhJ4j6cufK1W",
    "oauth_token_secret": "XXXXXXXXXXXXXXXXXXXX8Kf82k65JzIcMU7QUp54ssPEzJd7my"
}

tumblr.py:

import json

import requests
from requests_oauthlib import OAuth1

#gets the values for the variables
with open("API.json") as f:
    credentials = json.load(f)

#prints them to double check they are being read correctly
print(credentials)

#sets oauth for the connection
oauth = OAuth1(
    credentials['client_key'],
    credentials['client_secret'],
    credentials['oauth_token'],
    credentials['oauth_token_secret']
)

#check post that should return various blog stats
r = requests.get("http://api.tumblr.com/v2/user/info", auth=oauth)
print(r)
print(r.content)

Output (redacted the oauth stuff):

$ bin/python tumblr.py
{'oauth_token_secret': 'XXXXXXXXXXXXXXXXXXXX8Kf82k65JzIcMU7QUp54ssPEzJd7my', 'client_secret': 'XXXXXXXXXXXXXXXXXXXX72A5HQO1axydP5nlOWCTQx4ECfXfyX', 'client_key': 'XXXXXXXXXXXXXXXXXXXXdG7zXIMcDidwQ5pMHuQTbxyhNINrCE', 'oauth_token': 'XXXXXXXXXXXXXXXXXXXX8WAnqMBWaAdnGhnc4gWhJ4j6cufK1W'}

So now that I've tested your code out for myself:

• How did you get the oauth_token and oauth_token_secret? I got mine by clicking "Explore API" on the Applications developer page.
• You don't need to call readAPI.close(), as the with block automatically closes the file for you (see the official docs).
• I used JSON for storing and reading the credentials, that way I'm 100% sure that I'm getting the correct strings. The code is cleaner too. I'm still suspicious about the way you're reading lines from the file and slicing them.
• Try printing r.content in your code the same way I am. Does it give you a more descriptive error message than "401 Unauthorized"?
