⚙️ Using

Example using json payload inside your jwt token. Don't forget that the more payload in your token, the more it weighs

// jwt tokens
jwt::token jwt_access("access", "secret", "quarkpunk", 5);
jwt::token jwt_refresh("refresh", "secret", "quarkpunk", 1500);

// your json payload data
const json data = {
    { "id", "68b1a86e5bfc86a7fc048623" },
    { "session", "ab8214302e" },
    { "role", "admin" }
};

// export tokens to string
jwt_access.to_string("data", data);
jwt_refresh.to_string("data", data);

Token verification, everything is simple, verification returns true or false, as well as json payload in case of successful validation

// this is for example your http request
const std::string token_string = req.body();

// result validate json payload
json json_data;

// validate tokens
bool valid_access = jwt_access.validate(token_string, "data", json_data);
bool valid_refresh = jwt_refresh.validate(token_string, "data", json_data);

There is also an easier way if you only need the id in your token

// export tokens to string
// insert only id field
std::string access = jwt_access.to_string("68b1a86e5bfc86a7fc048623");
std::string refesh = jwt_refresh.to_string("68b1a86e5bfc86a7fc048623");

// validate tokens
// check only id field
std::string return_id;
jwt_access.validate(access, return_id);
jwt_access.validate(refesh, return_id);
