我使用了联表查询，读取出了1个想要的数据，相关代码如代码1所示。然后我借用变量i想要让它显示在屏幕上，相关代码如代码2所示。 但是尽管我已经把读取的数据量降低到了1个，在屏幕上显示的还是i的位置显示的是[object Object]，我想知道正确的显示方法是什么呢？ 代码2： queryData:function(){ wx.cloud.callFunction({ name: "connect", }).then(res=>{ console.log(res) this.setData({ i: res }) }) 代码1： // 云函数入口文件 const cloud = require('wx-server-sdk') cloud.init({ env: cloud.DYNAMIC_CURRENT_ENV }) // 使用当前云环境 const db = cloud.database() const _ = db.command const $ = _.aggregate // 云函数入口函数 exports.main = async (event, context) => { return await db.collection('books').aggregate() .lookup({ from:"author", // localField: 'authorid', // foreignField: 'number', // as: 'newlist' }) .match({ name: "《小王子》" }) .replaceRoot({ newRoot: $.mergeObjects([$.arrayElemAt(['$newlist', 0]), '$$ROOT']) }) .project({ _id:0, authorname:1, }) .end() // return db.collection("books").aggregate() // // .lookup({ // from:"author", // // localField: 'author', // // foreignField: 'number', // // as: 'newlist' // // }).end({ // success:function(res){ // return res.data.name; // }, // fail(error) { // return error; // } // }) }
