   或下载到本地安装：

declare let cordova:any;

initJpush() {
window.plugins.jPushPlugin.init();
window.plugins.jPushPlugin.setAlias({"sequence":1,"alias":this.identifierNumber}, (okData)=> {
this.utils.showToast({msg: 'jpush ok'});
},
(failData)=> {
this.utils.showToast({msg: 'jpush fail '+failData});
});
}
