MUI开发APP过程中遇到的扫码广播问题（Zebra斑马PDA）

mui.plusReady(function(){
scanReady();
})
function scanReady() {
var main = plus.android.runtimeMainActivity(); //获取activity
var context = plus.android.importClass('android.content.Context'); //上下文
var receiver = plus.android.implements('io.dcloud.feature.internal.reflect.BroadcastReceiver', {
onReceive: getReceive //实现onReceiver回调函数
});
var IntentFilter = plus.android.importClass('android.content.IntentFilter'); //引入过滤器
var Intent = plus.android.importClass('android.content.Intent');
var filter = new IntentFilter();
// filter.addAction("lachesis_barcode_value_notice_broadcast"); //监听扫码广播 //com.android.scanservice.scancontext
filter.addAction("com.android.scanservice.scancontext");
//filter.addAction("android.intent.action.SCANRESULT");
main.registerReceiver(receiver, filter); //注册监听
}
function getReceive(context, intent) {
//console.log(intent.getStringExtra("data"));
var mgs = intent.getStringExtra("data");
console.log(plus.device.model);
alert(mgs);
}
斑马PDA中没有设置广播数据标签的选项，请问intent.getStringExtra("data");这其中的参数改怎么设置？
