I have the same issue, any solution yet?

Curly brackets are not required!!!!! clientId: 1111 clientSecret: nddfdf7979df

silpol commented 9 years ago

@kjgarza curly brackets cause issue #2 Once I have removed them, I got towards login and after login I bumped into issue described in this report, literally (minus hashes and other possible ephemerals).

silpol commented 9 years ago

@smidm , @akselx and @kjgarza - have you managed to get down the bottom of this bug? or do we have to disturb @MendeleyStack to help us?

Hello,

I'm trying to find someone with Ubuntu installed in our team. Stand by.

Joyce-Stack commented 9 years ago

I am currently looking into this but I need to fix this issue first as I can't proceed until then - https://github.com/Mendeley/mendeley-api-python-example/issues/4

Joyce-Stack commented 9 years ago

I have had colleagues run this example and get successful responses using:-

I re-cloned this project on my Macbook and was able to rerun it successfully. Also, I went to the developer portal and regenerated my secret.

Can you try and do a pip uninstall all - http://stackoverflow.com/questions/11248073/what-is-the-easiest-way-to-remove-all-packages-installed-by-pip

livia-b commented 8 years ago

I also came across this problem, and somehow it worked after regenerating the secret, clearing cookies, changing browser ... hope that helps (mac, python 2.7, chrome and firefox)

This is due to redirect url. If you are running locally like I am your site runs on: http://127.0.0.1:5000/ but your redirect URL is set to http://localhost:5000/oauth which are two sites in terms of cookies so cookies can't be found and hence the key error. Change it to http://127.0.0.1:5000/oauth

michaelplews commented 8 years ago

@StankoPalko do you mean change the URI to http://1270.0.1:5000/oauth in the mendeley-example.py file? or on dev.mendeley.com?

This solved the issue for me:
