acurl 🔓
A simple authentication wrapper for cURL
Usage
Usage is exactly like curl, with one exception. If the first argument equals one of the blocks in the config file, it will not be sent to curl, but rather load the configuration.
acurl <curl args>will use default configuration.acurl test <curl args>will use default + test configuration.
Example:
acurl test https://example.com/ -iXPOST -H 'Content-Type: application/json' -d '{"x": 10}'
Configuration
acurl requires a config at ~/.config/acurl/config.json with a few fields.
Currently only json responses are supported. Here is an example where we fetch tokens from auth0:
{
"default": {
"authorization_url": "https://example.eu.auth0.com/oauth/token",
"request_body": {
"grant_type": "client_credentials",
"client_id": "default_client_id",
"client_secret": "default_client_secret",
"audience": "api_identifier"
},
"token_field": "access_token",
"expiration_field": "expires_in"
}
}Configuration overriding
Any other names than default can be used to override default configuration when calling acurl.
Example:
acurl test https://example.com/ -XPOST -H 'Content-Type: application/json' -d '{"x": 1}'
Will use configuration from test block to override.
It will use test_client_id and test_client_secret in the request body, and still keep all the other settings from the default block (Including other fields in the request body).
