Laravel 5.4 Passport-API无法设置30天到期令牌

I am Using Laravel 5.4 Passport Authentication. I have a problem to set API token expire date for 30 days. I have tried given code in Laravel documentation but it's not working. In the database, it's showing one year default token expiration date.

I have used

public function boot(){

    $this->registerPolicies();

    Passport::routes();

    Passport::tokensExpireIn(Carbon::now()->addDays(30));

}

if there is any solution please suggest me.

Thanks

i also got same issue so.. i used like that

try to change directly in PassportServiceProvider.php

go to PassportServiceProvider.php path should be like this

projectName/vendor/laravel/passport/src/PassportServiceProvider.php

and fine this line

new PersonalAccessGrant, new DateInterval('P1Y')

for example set expiry 1 month then

new PersonalAccessGrant, new DateInterval('P1M')

for example set expiry 1 week then

new PersonalAccessGrant, new DateInterval('P1W')

for example set expiry 5 DAYS then

new PersonalAccessGrant, new DateInterval('P5D')

for more DateInterval see
