前端实现的方法：

let temPrams = data.info
               temPrams.timestamp = parseInt(data.info.timestamp)
               plus.payment.request(
                 this.channel,
                 temPrams,
                 res => {
                   plus.nativeUI.alert('支付成功！', function() {
                   
                   })
                 },
                 error => {
                   plus.nativeUI.alert('支付失败：' + error.code)
                 }
               )
