setUserStorage 接口签名错误 - WXOPEN Club

setUserStorage 签名内容为{“kv_list”:[{“value”:{“wxgame”:{“update_time”:1529744189901,“grade”:10,“vip”:0}},“key”:“freeMode”}]}

value是string类型

const strValue = JSON.stringify({"wxgame":{"update_time":1529744189901,"value":10})

const kvList = {"kv_list":[{"key":"freeMode", "value":strValue}]}
