两个select2可以正常工作，但不能从ajax获取数据

$('#mySelect2').select2({
    ajax: {
        url: 'https://api.example.com/data', // 确保 URL 正确
        dataType: 'json',
        delay: 250,
        data: function (params) {
            return {
                q: params.term, // 搜索关键词
                page: params.page
            };
        },
        processResults: function (data, params) {
            params.page = params.page || 1;
            return {
                results: data.items,
                pagination: {
                    more: (params.page * 30) < data.total_count
                }
            };
        },
        cache: true
    },
    minimumInputLength: 1,
    templateResult: formatRepo,
    templateSelection: formatRepoSelection
});

function formatRepo(repo) {
    if (repo.loading) {
        return repo.text;
    }
    var markup = "<div class='select2-result-repository clearfix'>" +
        "<div class='select2-result-repository__title'>" + repo.name + "</div></div>";
    return markup;
}

function formatRepoSelection(repo) {
    return repo.name || repo.text;
}

{
    "items": [
        { "id": 1, "text": "Option 1" },
        { "id": 2, "text": "Option 2" }
    ],
    "pagination": {
        "more": true
    }
}

const express = require('express');
const cors = require('cors');
const app = express();

app.use(cors());
