超图微服务云套件大版本升级时，有时候会涉及服务的迁移或重新发布，此时需要对服务进行备份，以免重新发布服务出现漏的，便于核对。本文通过fetch实现了服务的备份，备份成果以数组对象形式存储在txt里下载下来存储。

    <!--    设计2个变量：urls列表，Authorization-->
    //Authorization：打开云套件服务实例，点击编辑，从抓到的请求头里获取Authorization值
    //urls：NGINX代理到本地后直接切换页面一次抓取所有内容。

    //待备份的服务列表
    const urls = [
        //形如 'http://localhost:31111/dashboard/web/api/service/instances?componentName=spatialanalysis-JKC_MLX&interfaceName=restjsr'
    ];
    //服务配置文件具体内容数组对象myservice，也就是供下载的txt文件内容
    const myservice = []
    // json1为分页里抓取到的含url信息的json，需要提取到urls里面
    let json1 = {
        "total": 169,
        "list": [
            {
