钉钉客户端开发dd.biz.util.openLink执行无反应，不太明白dingtalk.js中的相关代码

这是js中的相关代码：

!function(a){"use strict";
    function b(a,b,c){
    for(var d in b)c?a[d]=b[d]:a[d]=void 0!==a[d]?a[d]:b[d]}
function c(a,c){if("undefined"==typeof WebViewJavascriptBridge)return console.log("WebViewJavascriptBridge未定义，请在钉钉app打开该页面");
var d=c||{}
e=function(b){console.log("默认成功回调",a,b)}
f=function(b){console.log("默认失败回调",a,b)}
g=function(){};d.onSuccess&&(e=d.onSuccess,delete d.onSuccess)
d.onFail&&(f=d.onFail,delete d.onFail),d.onCancel&&(g=d.onCancel,delete d.onCancel);
var h=function(a){var b=a||{},c=b.errorCode,d=b.result;"0"===c?e&&e.call(null,d):"-1"===c?g&&g.call(null,d):f&&f.call(null,d,c)},i=!1;
switch(a){
    case"device.notification.alert":b(d,{title:"",buttonName:"确定"});break;
    case"device.notification.confirm":case"device.notification.prompt":b(d,{title:"",buttonLabels:["确定","取消"]});break;
    case"device.notification.vibrate":b(d,{duration:300});break;
    case"device.accelerometer.watchShake":o.ios&&(i=!0,d.sensitivity=3.2);break;
    case"biz.util.openLink":b(d,{credible:!0,showMenuBar:!0});break;
