你可以利用login_redirect 滤器

文档中的示例与您的问题非常相似：

/**
 * Redirect user after successful login.
 *
 * @param string $redirect_to URL to redirect to.
 * @param string $request URL the user is coming from.
 * @param object $user Logged user\'s data.
 * @return string
 */

function wpse306427_login_redirect( $redirect_to, $request, $user ) {
    //is there a user to check?
    if (isset($user->roles) && is_array($user->roles)) {
        //check for subscribers
        if (in_array(\'subscriber\', $user->roles)) {
            // redirect them to another URL, in this case, the homepage 
            $redirect_to =  home_url();
        }
    }

    return $redirect_to;
}

add_filter( \'login_redirect\', \'wpse306427_login_redirect\', 10, 3 );
