怎么把接口请求回来的数据同步到data，我用的官方Promise写法。求大神指点。。。

分类：uni-app

data() {
return {
classdata:""
}
}
created() {
this.getdata()
console.log(this.classdata)//这里打印是空的
},
methods: {
getdata: async function () {
let CLASS = {}
CLASS.token = this.user.token
CLASS.orgid = this.user.id
CLASS.class = this.workData.clsid
let err,res;
[err,res] = await uni.request({
method: 'POST',
url: this.Url+'/getclass',
data: CLASS
});
this.classdata = res.data
console.log(this.classdata)//这里确有内容
console.log(res);
}
}
