salesforce前端的Map属性赋值问题
在Lightning前端画面中，有Map属性，从Apex取值之后，即使返回的是Map，也不能直接赋值，要循环变换一下赋值。
如有理解错误，请赐教哈。
代码如下：
Lightning前端：
Account:
{!rec.key}:{!rec.value}
Lightning前端Controller.js：
({
doInit : function(component, event, helper) {
const service = component.find('service');
let objectAPINameList = ['Account','Contact'];
let objectFieldAPINameMap = {'Account':['Name','Type']};
service.getFieldLabel(objectAPINameList,objectFieldAPINameMap,function(result){
console.log(JSON.stringify(result)); -->这句就是要测试一下能不能返回下面那个Apex返回的Map
//本来是想这一句应该就可以给前端Map变量赋值了，但是死活赋值不上
//component.set('v.contactFieldLabelMap',result['Account']);
//后来在这个上面看到，说不能直接搞，要转换一下
//https://salesforce.stackexchange.com/questions/140608/how-to-iterate-over-map-in-salesforce-lightning-component
var accountFieldLabelMap = [];
var retAccount = result['Account'];
for(var key in retAccount){
accountFieldLabelMap.push({value:retAccount[key], key:key});
}
component.set('v.accountFieldLabelMap',accountFieldLabelMap);
});
}
})
Apex后端：
这个有点儿复杂哈，代码贴出来可能意义也不大。
大概就是返回一个这个的Map：

"Name": "Account Name",
"Type": "Account Type"
