update的时候明明用了where为啥还把所有的记录都更新了呢？ 前几天测试还是好的。前几天不会更新所有记录，

// 云函数入口文件

const cloud = require('wx-server-sdk')

cloud.init({

traceUser: true

})

// 云函数入口函数

exports.main = async(event, context) => {

try {

delete event.data_regist['__webviewId__']

delete event.data_regist.records_data['__webviewId__']

const db = cloud.database()

await db.collection('users_info').where({

openid: event.data_regist.openid

}).update({

data: event.data_regist,

}).then(res => {

console.log(res)

})

} catch (e) {

console.error(e);

}

return {

}

}
