Я новичок, чтобы реагировать, и мне было интересно, как внутренне перенаправить ваши страницы в reactjs. У меня есть две страницы, называемые register и register2. На странице регистрации я просто проверяю, существует ли электронное письмо в базе данных или нет, и если оно не существует, оно перенаправляет на страницу register2 для создания полной учетной записи с именем пользователя и паролем. Однако в адресной строке выглядит некрасиво, чтобы показать что-то вроде register2. Поэтому мне было интересно, есть ли способ, с помощью которого я могу внутренне перенаправить, не меняя адрес в адресной строке на register2, чтобы он оставался регистром на протяжении всего процесса создания учетной записи.
Я создал codeandbox для отображения проблемы
