网页版支付宝支付，提示“非法的时间戳参数”？

invalid-timestamp

api说是这样的格式，我是这样拼接的,

---

new Date().toLocaleTimeString()
--> "下午3:18:20"

---

var date = new Date();
var dateStr = date.getFullYear()+'-'+(date.getMonth()+1)+'-'+date.getDate()+' '+date.getHours()+':'+date.getMinutes()+':'+date.getSeconds();
alert(dateStr)
