Question

在我的 buy.js 中，我首先检查用户之前是否购买了我的包裹。如果没有，我打电话给买方法开始购买。

我目前收到错误：

Error in event handler for (unknown): TypeError: Cannot read property 'details' of undefined
    at Object.onLicenseUpdate [as success] (buy.js:52:45)
    at buy.js:1:397

控制台中收到的数组的屏幕截图及错误：

以下是有问题的代码：

function onLicenseUpdate(response) {
        console.log("onLicenseUpdate", response);
        var licenses = response.response.details;
        var count = licenses.length;
        for (var i = 0; i < count; i++) {
          var license = licenses[i];
          purchasedPackages = licenses[i].response.details.sku;
          if (purchasedPackages == skuInit) {
            purchased = true;
          }
          addLicenseDataToProduct(license);

        }
        if (purchased == false) {
          buyProduct(skuInit);
        }
        //console.log("");
      }

完成Buy.js代码：

var prodButPrefix = "btnProdID-";
var statusDiv;

function init() {
  console.log("App Init");

我也知道这不是最有效的方法。有没有办法可以将所有购买的SKU存储在一个阵列中（或任何其他有效的方式）？

details数组没有response属性。该数组已经是包含sku属性的对象列表。

要解码response，您需要onLicenseUpdate()功能更像：

function onLicenseUpdate(response) {
  console.log("onLicenseUpdate", response);
  var purchased = false;
  var licenses = response.response.details;
  var count = licenses.length;
  for (var i = 0; i < count; i++) {
    var license = licenses[i];
    purchasedPackages = license.sku;
    if(purchasedPackages == skuInit){
      purchased = true;
    }
    addLicenseDataToProduct(license);
  }
  if (purchased == false){
    buyProduct(skuInit);
  }
  //console.log("");
}

虽然，我会使用forEach代替for：

function onLicenseUpdate(response) {
  console.log("onLicenseUpdate", response);
  var purchased = false;
  var licenses = response.response.details;
  licenses.forEach(license=>{
    purchasedPackages = license.sku;
    if(purchasedPackages == skuInit){
      purchased = true;
    }
    addLicenseDataToProduct(license);
  }
  if (purchased == false){
    buyProduct(skuInit);
  }
  //console.log("");
}
