unicloud云数据库，获取json格式时输出为："__ob__": {"dep": {...

问题

使用云函数获取云数据库的数据时，发现json对象没有赋值前打印出来是正常的，但是赋值之后打印出来就变成了如下：

{  
    "affectedDocs": 2,  
    "data": [{  
        "__ob__": {  
            "dep": {  
                "id": 672,  
                "subs": [{

                    "before": "function before () {\n      if (vm._isMounted && !vm._isDestroyed) {\n        callHook(vm, 'beforeUpdate');\n      }\n    }",

    }]

解决办法

事实上这个是vue的ob: Observer这些数据是vue这个框架对数据设置的监控器。不能够直接打印但是也是可以获取数据的

const va = uniCloud.importObject("getques")  
const ans = await va.getList()  
this.res = ans.data//给本地的res对象赋值  
console.log(ans)//这样打印出来就是如上代码一样是看不到数据的

console.log(this.res.data[0].que)//这样打印就可以打印出正常的数据了打印结果是

其实可以正常操作了，在v-for中遍历

得到结果
