            var IAPOrders;  
            var _this = this;  
            // 获取支付通道  
            plus.payment.getChannels(  
                function(channels) {  
                    console.log(channels);  
                    for (var i in channels) {  
                        if (channels[i].id == 'appleiap') {  
                            console.log(channels[i]);  
                            var iapChannel = channels[i];  
                            iapChannel.requestOrder(  
                                ['monthVips','fanyin.year.vip'],  
                                function(event) {  
                                    console.log('--------------');  
                                    console.log(event);  
                                },  
                                function(errormsg) {  
                                    console.log('获取支付通道失败：' + errormsg.message);  
                                }  
                            );  
                        }  
                    }  
                },  
                function(e) {  
                    console.log('获取支付通道失败：' + e.message);  
                }  
            );  
        },
