如何从管理页面导出模型与用户名，而不是用户id？

async function exportUsernames() {
    try {
        const response = await fetch('/api/export-usernames');
        if (!response.ok) {
            throw new Error('Network response was not ok ' + response.statusText);
        }
        const data = await response.blob();
        const url = window.URL.createObjectURL(data);
        const a = document.createElement('a');
        a.href = url;
        a.download = 'usernames.csv';
        document.body.appendChild(a);
        a.click();
        a.remove();
    } catch (error) {
        console.error('There has been a problem with your fetch operation:', error);
    }
}

async function fetchUsernames(userIds) {
    try {
        const response = await fetch('/api/users', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json'
            },
            body: JSON.stringify({ userIds })
        });
        const users = await response.json();
        return users.map(user => user.username);
    } catch (error) {
        console.error('Error fetching usernames:', error);
    }
}
