passport-oauth | OAuth 1.0 and 2.0 authentication strategies | Authentication library

Here's the code i typed.

On reading the logs it seems as if there is a problem in google OAuth because its callback URL is localhost:3000. So I am not unable to fix it.

These are the heroku logs

I would like to use Oauth1.o to get credentials from a provider but I am halfway stuck. I am using passportjs for the implementation.

Here is the brief code:

1. oauth.js

I'm trying to authorize my node application via fusionauth with passport and express and I'm getting a node error from the fusionauth Callback "Failed to obtain access token" after login to fusionauth. I'm not sure why the fusionauth response doesn't include the token?

fusionauth authorize link with callback fusion_auth_server:9011/oauth2/authorize?response_type=code&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Foauth2%2Fcallback&client_id=42a5####-####-####-####-########

So I'm trying to save an access token to the state within Koa, just for use later and saving having to pass it around the client.

Following the passport oauth2 documentation for Koa, I'm struggling to persist anything to ctx.state...

Koa / passport oauth2 setup:

I'm trying to embed google authentication in Node.js using passport and google passport-google-oauth20. The problem is that when the google callback route opens up I get:

I am using the following library:

passport-oauth2-password-grant

What I'm trying to do is the following:

1. Authenticate to the API (username / password)
2. Get the Access token
3. Get the user profile from the API
4. Log the user in using passport

I'm using the following implementation:

I am implementing Apostropecms authentication with fusionauth. For this I use the apostrophe-passport and passport-oauth2 modules. I am having problems at a step in the flow where I must obtain user information. I don't get user information from fusionauth by /oauth2/userinfo or /api/user.

I modified the passport-oauth2 strategy to adapt it to the fusionauth flow.

This is the error: InternalOAuthError: Failed to fetch user profile

I have a stand alone oauth2 identity provider that is working. Now I'm developing a consumer that will authenticate users with this stand alone provider.

I'm following this tutorial about passport and Google Auth:

I'm trying to use this information to use passport-oauth2 to work as a client. I have made some changes in the code provided in the tutorial above by following the official documentation on passoprt-oauth2.

I think that I have some problem in the callback function where expressjs receive the confirmation of authentication and info about the user. I don't understand how to use this information.

Here is the code of my app.js
