                    uni.requestPayment({  
                     provider: 'alipay',  
                     orderInfo: result.data.data,  
                     success: function (res) {  

                      console.log('success:' + JSON.stringify(res));  
                     },  
                     fail: function (err) {  
                      console.log('fail:' + JSON.stringify(err));  
                      // console.log(orderInfo);  
                     }  
                    });
