ioni3 http请求数据绑定时数组嵌套的显示问题

最近使用ionic3时，http请求之后，data返回来了，控制台可以console.log打印出来，但是挂不到页面上；

{
"city": "00000",
"code": "string0",
"flag": "0000",
"info": {
"contact": "13000000000",
"imgList": [
"0000000000"
],
"subject": "string",
"workTime": "9:00-21:000000"
},
"location": {
"x": 0,
"y": 0
},
"message": "0000......",
"name": "0000",
"provice": "string",
"shopImg": "assets/img/6.jpg",
"sid": "string",
"tags": [
"000000"
],
"workStatus":
"00000",
"zone": "string"
}

想要挂info里面的contact的电话号码，

http请求代码如下，都可以console.log，

ngOnInit(): void {
this.shops=this.http.get('assets/data/data.json');
this.shops
.map(res
=> res.json())
.subscribe(
data => {
console.log(data);
this.results =
data;
console.log(this.results.info);

console.log(this.results.info.contact);
})

html如下：

<p>{{ results.info.contact }}</p>

怎么样都不显示，弄了好久；

解决方法如下：

results: any = {
info:{} };

注意{},就是加上它就好了！
