PC端免登.Net实现，调不了JS，急啊！！！

<script type="text/javascript" src="http://g.alicdn.com/dingding/dingtalk-pc-api/2.3.1/index.js" ></script>
//jsapi的配置。
                DingTalkPC.config({
                    appId: _config.appId,
                    corpId: _config.corpId,
                    timeStamp: _config.timeStamp,
                    nonceStr: _config.nonce,
                    signature: _config.signature,
                    jsApiList: ['runtime.info',
                        'biz.contact.choose',
                        'device.notification.confirm',
                        'device.notification.alert',
                        'device.notification.prompt',
                        'biz.ding.post',
                    'runtime.permission.requestAuthCode',
                    'device.geolocation.get',
                    'biz.ding.post',
                    'biz.contact.complexChoose']
                });



                DingTalkPC.ready(function (res) {

                    //获取免登授权码
                    DingTalkPC.runtime.permission.requestAuthCode({
                        corpId: _config.corpId,
                        onSuccess: function (result) {
                            location.href = "ServerApi.aspx?code=" + result["code"];
                        },
                        onFail: function (err) { }

                    });


                    //这里写一个简单的jsapi的弹用，其它api的调用请参照钉钉开发文档-客户端开发文档
                    DingTalkPC.device.notification.alert({
                        message: "测试弹窗",
                        title: "提示",//可传空
                        buttonName: "收到",
                        onSuccess: function () {
                            /*回调*/
                        },
                        onFail: function (err) { }
                    });

                });

DingTalkPC.ready(function (res) 没有执行。
