Working
The authentication class checks for the token in two locations:

HTTP_AUTHORIZATIONenvironment variable:It first checks if token is passed using
Authorizationrequest header. The value should be of formBearer <token>. TheAuthorizationheader name and token prefixBearercan be customzied using optionsheaderandprefixrespectively.Note: Some servers don't populate
$_SERVER['HTTP_AUTHORIZATION']whenAuthorizationheader is set. So it's upto you to ensure that either$_SERVER['HTTP_AUTHORIZATION']or$_ENV['HTTP_AUTHORIZATION']is set.For e.g. for apache you could use the following:
-
The query string variable specified using
parameterconfig:Next it checks if the token is present in query string. The default variable name is
tokenand can be customzied by using theparameterconfig shown above.
Token Generation
You can use \Firebase\JWT\JWT::encode() of the firebase/php-jwt
lib, which this plugin depends on, to generate tokens.
The payload should have the "sub" (subject) claim whos value is used to query the Users model and find record matching the "id" field.
You can set the queryDatasource option to false to directly return the token's
payload as user info without querying datasource for matching user record.
