uni-app 蘋果內購支付及獲取蘋果支付成功信息

先在頭部定義商品id 全部商品id (在蘋果商店申請的真實商品id)

let iapChannel = null;
var productId = 'lvbi_a';
var productIds = ['lvbi_a'];

進入頁面就判斷

//1.獲取支付渠道
            plus.payment.getChannels((channels) => {
                for (var i in channels) {
                    var channel = channels[i];
                    //蘋果支付
                    if (channel.id === 'appleiap') {
                        iapChannel = channel;
                        this.requestOrder(); //關鍵
                    }
                }
                if (!iapChannel) {
                    that.errorMsg()
                }
            }, (error) => {
                that.errorMsg()
            });

requestOrder() {
    iapChannel.requestOrder(productIds,     
              (orderList) => { //必須調用此方法才能進行 iap 支付
        uni.hideLoading();
    }, (e) => {
        uni.hideLoading();
            this.errorMsg()
    });
},        

調接口獲取真實的商品id

                        // 獲取頁面內容
            getAppleProducts() {
                AppleProducts({
                    openid:this.openid,
                    token:this.tpken
                }).then(res =>{
                    if(res.code == 1){
                        this.data = res.data;
                        this.price = this.data.products[0];
                        productId = 
                                                this.data.products[0].product_id;
                        productIds =     
                                                this.data.products_ids;
                    }
                })
            },    

確定支付

topupprice() {
                let that = this;
                uni.showLoading({});
                uni.requestPayment({
                    provider: 'appleiap',
                    orderInfo: {
                        productid: productId
                    },
                    success: (e) => {
                        uni.hideLoading();
                         var  statement = {  
                                productid: productId  
                            }  
                            // 支付成功查詢訂單
                            plus.payment.request(iapChannel, statement, function(res){
                                paysuccers({
                                    data:{

                                        receipt_data:JSON.stringify(res)
                                    }
                                }).then(tow =>{

                                    if(tow.code == 1){
                                        uni.showToast({
                                            title:tow.msg,
                                            icon:'none'
                                        })
                                    }else{

                    },
                    fail: (e) => {
