return { event, xm: 2, sushe: userinfos['sushe'], openid: wxContext.OPENID, appid: wxContext.APPID, unionid: wxContext.UNIONID, } |
我想获取查询到的结构，然后赋值到userinfos中，然后再用return返回userinfos中的数据，但是在括号外输出的结果为undefinded，该怎么写才能获取到userinfos['sushe']的值。
let p = new Promise((resolve, reject) => {
db.collection('user').where({
_openid: wxContext.OPENID
}).get({
success: res => {
resolve(res)
},
fail: err => {
reject(err)
}
})
})
return await p;
哈哈，来晚了。看描述解决了。
let { data = [{}] } = await db.collection('user').where({
_openid: wxContext.OPENID
}).get(),
sushe = data[0]
event = sushe
return {
event,
xm: 2,
sushe: sushe,
openid: wxContext.OPENID,
appid: wxContext.APPID,
unionid: wxContext.UNIONID,
}
