} else {
uni.navigateTo({
url: '/pages/blind_box/open_blind?blindId=' + that.blindId +
'&parentOrderNo=' + that.parentOrderNo + '&price=' + that.price
})
}

          },  
          fail: function(res) {  
            console.log('支付过程失败:' + JSON.stringify(res))  
            that.$api.msg('支付取消')  
          },  
          complete: function(res) {  
            console.log('支付过程结束')  
          }  
        })

调用后端微信支付下单接口后，调用uni.requestPayment后报错了
