Question

如何重写Laravel 的attempt方法

Answer 1

默认是使用eloquent作为认证驱动器，所以看看Illuminate\Auth\EloquentUserProvider里面的实现
public function validateCredentials(UserContract $user, array $credentials)
{
$plain = $credentials['password'];

return $this->hasher->check($plain, $user->getAuthPassword());
}

所以如果要改验证的逻辑，可以继承原有的驱动器，然后重写validateCredentials里面的逻辑
class TestUserProvider extend EloquentUserProvider
{
public function validateCredentials(UserContract $user, array $credentials)
{
$plain = $credentials['password'];

return md5($plain) == $user->getAuthPassword();
}
}

最后设置驱动器，建议加载AppServiceProvider的boot()里面
Auth::setProvider(new TestUserProvider());
