AuthenticationError when connecting to Reddit

[kriss6557]

Hi,

I’m using gallery-dl within docker and it works perfectly with Pinterest.


I tried to do the same with Reddit, but run into an authentication error.

Here are the steps:
I have a created a script application on reddit (Script for personal use. Will only have access to the developers accounts) called my_appname which provides a client-id and a client-secret.

Then I used a python script which asks Reddit to allow my_appname to

• Access posts and comments through my account.
• Maintain this access indefinitely (or until manually revoked).
  Once allowed it sends me back to the redirect URL with a code at the end.
This code ends with some characters (#_) that seems to be excluded to generate the refresh-token
  I add this refresh token to my gallery-dl.conf file below



{
    "extractor": {
        "reddit": {
            "video": true,
            "comments": false,
            "client-id": "qGXXXXXXXXXXXXXX",
            "client-secret": "3XXXXXXXXXXXXXXXXXX",
            "user-agent": "Python:my_appname:v1.0 (by /u/my_username)",
            "refresh-token": "287XXXXXXXXXXXXXXXXXXXXXXXX"
        }
    },
    "output": {
        "mode": "auto",
        "path": "/gallery-dl",
        "progress": true
    },
    "downloader": {
        "http": {
            "rate": "500k",
            "timeout": 30,
            "retries": 4,
            "verify": true
        }
    }
}

Then when running with a URL like https://www.reddit.com/user/my_username/saved I receive:

What am I missing? Can you please help.
Thank you

You most likely forgot the select "installed app" step when registering a new application. There shouldn't be a client-secret, only client-id and user-agent.

Thank you there is progress now.
I reach:

gallery-dl    | Waiting for response. (Cancel with Ctrl+c)
gallery-dl    | [oauth][info] Please open this URL in your browser:

but as this is a standalone docker container, I'm not sure this is feasible / automatable.
I believe this where the scriopt application at Reddit was made for (my initial configuration)

It appears you ran gallery-dl oauth:reddit.
You managed to get a refresh-token with it before. Just do the same thing again as you did the first time.

Only client-id, user-agent, and (optionally) refresh-token are necessary for authentication and they are all static, constant values once they are set up.

Hi,
So I had use the gallery-dl executable for windows because it has a web browser, I miss on my docker server.
Then run :

gallery-dl --clear-cache reddit
gallery-dl oauth:reddit -c ./gallery-dl.conf

It open the web browser and asks to allow the reddit app then displays the refresh-token

I had to add the refresh-token field and value in my gallery-dl.conf file so that it can work.

Thank you very much for your help.
