title: Invalid authorization code when trying to get access token in spotipy
body: <p>I am trying to authenticate my python app to a specific user using spotipy.  I have done this before with a few other users with no problems.  This user however each time I try I keep getting '{"error":"invalid_grant","error_description":"Invalid authorization code"}'</p>
  
  <p>I have also tried manually a couple different ways including curl:</p>
  
  <blockquote>
    <p>curl -H "Authorization: Basic OTQxNDliNjI3...WRhMzk5YTY2ZTliZWY=" -d grant_type=authorization_code -d code=AQByvdq4Vr9-L_ZLrySeTOx...pm1vmb8vwGe2GUXcmTY#<em>=</em> -d redirect_uri=http%3A%2F%2Flocalhost%3A8888%2Fcallback <a href="https://accounts.spotify.com/api/token" rel="nofollow">https://accounts.spotify.com/api/token</a>
    {"error":"invalid_grant","error_description":"Invalid authorization code"}</p>
  </blockquote>
  
  <p>I have tried both putting the client_code and client_secret in the header (as shown above) and in the post body both with the same error</p>
  
  <p>keep in mind I am using the exact code I get from my callback url as soon as I can (cut and paste) and like I said before, this method has worked with other users with no problems.  Can anyone think of anything else I can try?</p>
