kvdata多个key时应该怎么写啊？~~
我这么写会报错，说“KVDataList must be an Array”
let kvdata =new Array();
let data1={key:rankString,value:this.rankScore};
let data2={key:rankTimeString,value:date.getTime()};
kvdata.push(data1);
kvdata.push(data2);
wx.setUserCloudStorage(kvdata);
let gameScoreData = {wxgame: {score:16,update_time:newDate().getTime(),},cost_ms:36500}let userKVData = {key:"score",value: JSON.stringify(gameScoreData),}wx.setUserCloudStorage({KVDataList: [userKVData],success:function(res) {console.log('--success res:', res);},fail:function(res) {console.log('--fail res:', res);},complete:function(res) {console.log('--complete res:', res);},});测过了，能用。
setUserCloudStorage 的调用写错了，应该是这样
wx.setUserCloudStorage({KVDataList: yourKVDataList,success: res => console.log(res),fail: res => console.log(res)})至于拉取为 0，应该就是你之前 set 失败所以没有数据写入。
还有，要拉取的时候要怎么写呢？
wx.getFriendCloudStorage(
{
keyList: ["rankScore","rankTime"],
success: res => {
let data = res.data
this.drawRankList(data)
},
})
这么写得到的KVDataList元素个数是0 （KVDataList: Array(0)）
