oauth2cli 
This is a Go package for better user experience with OAuth 2.0 or OpenID Connect (OIDC) on command line interface. It allows simple and easy user interaction with the Authorization Code Grant Flow using a local server.
See the example using oauth2cli.
Why
Typical implementation of the OAuth 2.0 Authorization Code Grant requires complicated user interaction, for example:
- User runs the command on a terminal.
- User opens the URL shown on the command.
- User logs in to the provider.
- User copies the code shown on the browser.
- User pastes the code on the terminal.
- User can access to the API using the token.
By using oauth2cli, user interaction becomes simple and easy as follows:
- User runs the command on a terminal.
oauth2cliopens the browser automatically.- User logs in to the provider.
oauth2cligets a token from the provider.- User can access to the API using the token.
How it works
oauth2cli performs the following steps:
- Start a local server at the port.
- Open a browser and navigate it to the local server.
- Wait for the user authorization.
- Receive a code via an authorization response (HTTP redirect).
- Exchange the code and a token.
- Return the code.
