How to verify JWT Token in CodeIgniter 3.x for every request from Client

php codeigniter jwt restful-authentication

then load or auto load this helper.

This will give you the token

helper_name::encode(data, secure_key)

To verify you need to use

helper_name::decode(token,secure_key,true)

it will give you data which you have encoded or it will give you false if token is not valid.

php codeigniter jwt restful-authentication

Important Update:

I updated the repository to CodeIgniter 4. Developers who want to use CodeIgniter 3, use following command:

git checkout CI3

Original Answer:

I have created a repository which contains this code including helper class.

Since this is a sample code, I am not expecting any username or password.

GET auth token

URL: http://host/CodeIgniter-JWT-Sample/auth/tokenMethod: GET

Check decoded token

URL: http://host/CodeIgniter-JWT-Sample/auth/tokenMethod: POSTHeader Key: AuthorizationValue: Auth token generated in GET call
