手机应用多页方式实现时，钉钉认证时间过长，求解决方案？

有两个页面，一个是my,一个是detail
通过调试日志时间戳看：
dd.config 到完成 dd.requestAuthCode完成耗时都将近1秒和超过1秒。尤其是：requestAuthCode 耗时较长。
请教，应用在多页实现过程中，这种问题怎么处理？
Util.log("Before dd config", location.href.substring(location.href.lastIndexOf('/')+1));
dd.config({
    agentId: _config.agentId,
    corpId: _config.corpId,
    timeStamp: _config.timeStamp,
    nonceStr: _config.nonceStr,
    signature: _config.signature,

Util.log("End dd config", location.href.substring(location.href.lastIndexOf('/')+1));

dd.ready(function () {

    dd.runtime.info({

            Util.log("dd ready runtime success", location.href.substring(location.href.lastIndexOf('/')+1));
        },
        onFail: function (err) {
            Util.log("dd ready runtime failed", location.href.substring(location.href.lastIndexOf('/')+1));
        }
    });
    setTimeout(dd.runtime.permission.requestAuthCode({
        corpId: _config.corpId,

            Util.log("dd ready requestAuthCode success", location.href.substring(location.href.lastIndexOf('/')+1));
            dd.ui.pullToRefresh.disable();
            $.ajax({
                url: '/authUser',
                type: "GET",
                data: {"access_token": _config.token, "code": info.code},
                dataType: 'json',
                timeout: 9000,
                success: function (data, status, xhr) {
                    Util.log("dd ready ajax success", location.href.substring(location.href.lastIndexOf('/')+1));
