使用 Google Apps 脚本（WooCommerce Webhook）获取 JSON 数组中的 object 值

Question

我有一个 WooCommerce 网上商店，它使用 webhook 将创建的订单发送到 Google 电子表格。 我设法使它工作，除了一个（关键）步骤：我似乎无法正确循环遍历行项目的元数据。

在这里提供更多背景信息：它是一家销售蛋糕和馅饼等（行项目）的网上商店。 一个订单可以有多个产品，每个产品可以有多个元数据。 例如：产品（行项目）：蛋糕，元数据：蛋糕（键）尺寸：（值）小，（键）蛋糕上的文字：（值）蓝色文本，（键）蛋糕上的文字：“Hello World” （价值）。

我需要实现的是以下电子表格中的顺序示例（简化）：

姓名、email地址、取件日期、取件时间、取件地点、订单

Joe Deer，joe@deer.com，2020 年 10 月 10 日，10:00，面包店，1 x 红色天鹅绒蛋糕，小蛋糕，蛋糕上的蓝色文字，“Hello World”。 1 x 海龟蛋糕，大蛋糕蛋糕上没有文字。

请在下面找到 JSON Object 的示例以获取概览。 Object 的名称是 myData，因此可以使用 myData.line_items 访问行项目。

"line_items": [
{
  "id": 61458,
  "name": "Cupcake Mix 12 stuks",
  "product_id": 627,
  "variation_id": 0,
  "quantity": 1,
  "tax_class": "gereduceerd-tarief",
  "subtotal": "27.52",
  "subtotal_tax": "2.48",
  "total": "27.52",
  "total_tax": "2.48",
  "taxes": [
    {
      "id": 2,
      "total": "2.477064",
      "subtotal": "2.477064"
    }
  ],
  "meta_data": [
    {
      "id": 540340,
      "key": "Vanilla Buttercream Cupcake",
      "value": "yes"
    },
    {
      "id": 540341,
      "key": "Vanilla Confetti Cupcake",
      "value": "yes"
    },

我（相信我）需要实现的是在循环中添加一个循环，该循环遍历 line_items object 的 meta_data。 但是，我尝试了它（使用下面的代码），但无法使其工作。

    //this is a function that fires when the webapp receives a GET request
function doGet(e) {
  return HtmlService.createHtmlOutput("request received");
  Logger.log('GET received at: ' + timestamp);
}

//this is a function that fires when the webapp receives a POST request
function doPost(e) {
  var myData                 = JSON.parse([e.postData.contents]);
  var order_number           = myData.number;
  var order_created          = myData.date_created;
  var order_status           = myData.status;
  var product_name           = myData.line_items[0].name;
  var product_qty            = myData.line_items[0].quantity;
  var product_total          = myData.line_items[0].total;
  var order_total            = myData.total;
  var billing_email          = myData.billing.email;
  var billing_first_name     = myData.billing.first_name;
  var billing_last_name      = myData.billing.last_name;
  var payment_method         = myData.payment_method_title;
  var shipping_method        = myData.shipping_lines[0].method_title;
  var pick_up_location       = myData.meta_data[0]["value"];
  var pick_up_date           = myData.meta_data[1]["value"];
  var pick_up_time           = myData.meta_data[2]["value"];

  var pick_up_time_array     = pick_up_time.split(" - ");
  var pick_up_time_start     = pick_up_time_array[0];
  var pick_up_time_end       = pick_up_time_array[1];
  var shipping_total         = myData.shipping_lines[0].total;

  var lineitems=""
  for (i in myData.line_items)
  {
    var product_name         = myData.line_items[i].name;
    var itemName             = myData.line_items[i].name;
    var quantity             = myData.line_items[i].quantity;

     for (j in myData.line_items[1][j]) {
        var decorationitems = "Item: " + myData.line_items[1][j].key + " Optie: " + myData.line_items[1][j].value + '\n';
        var decoration = decoration+decorationitems; 
      }

    var product_items = quantity + " x " + itemName + '\n' + decoration + '\n';  
    var lineitems = lineitems+product_items;
}

var timestamp = new Date();
  var sheetActive = SpreadsheetApp.openById("<ID>");
  var sheet = sheetActive.getSheetByName("<NAME>");
  sheet.appendRow([timestamp,order_number,order_created,product_name,product_qty,product_total,order_total,billing_email,billing_first_name,billing_last_name,payment_method,shipping_method,pick_up_location,pick_up_date,pick_up_time,pick_up_time_start,pick_up_time_end,shipping_total,lineitems]);

}

你们能帮我解决for循环的部分吗？ 我真诚地希望我把我的问题说清楚了。 如果您还有任何问题，请告诉我！

Answer 1

这是一个循环，它根据您提供的代码遍历 line_items object 的 meta_data。

  var lineitems="";
  var decoration = "";
  for (var i in myData.line_items)
  {
    var product_name = myData.line_items[i].name;
    var itemName = myData.line_items[i].name;
    var quantity = myData.line_items[i].quantity;
    var metaData = myData.line_items[i].meta_data;

     for (var j in metaData) 
     {
       for (var key in metaData[j])
       {
         var decorationitems = "Item: " + key + " Optie: " + metaData[j][key] + '\n';
         decoration = decoration + decorationitems; 
       }
     }
    var product_items = quantity + " x " + itemName + '\n' + decoration + '\n';  
    lineitems = lineitems + product_items;

  }

//this is a function that fires when the webapp receives a GET request
function doGet(e) {
  return HtmlService.createHtmlOutput("request received bla");
}

//this is a function that fires when the webapp receives a POST request
function doPost(e) {
  var myData             = JSON.parse([e.postData.contents]);

  var shipping_address   = myData.shipping.address_1 +  ", " + myData.shipping.address_2 ;
  var shipping_post_code = myData.shipping.postcode;
  var payment_method     = myData.payment_method_title;
  var shipping_total     = (myData.shipping_lines.length > 0) ? myData.shipping_lines[0].total : '0';
  var product_total      = (myData.line_items.length>1) ? myData.line_items[0].meta_data[3].value.total_payable_amount : '-';
  var total_amount       = myData.total;
  var remaining_amount   = (myData.line_items.length>1) ? myData.line_items[0].meta_data[3].value.remaining_payable_amount : '-';
  var coupon_name        = (myData.coupon_lines.length>0) ? myData.coupon_lines[0].code : '-';

  var next_payment_date  = (myData.line_items.length>1) ? myData.line_items[0].meta_data[3].value.next_payment_date : '-';
  

  for (var i = 0; i < myData.line_items.length; i++){

  var product_id = myData.line_items[i].product_id;
  var product_name = myData.line_items[i].name;
  var product_qty = myData.line_items[i].quantity;
  var variation_id = myData.line_items[i].variation_id;
   

 }

  if (currency == 'SGD')
  sheet = SpreadsheetApp.getActive().getSheetByName('sg');
  else if (currency == 'MYR')
  if(product_id =='8348')
  sheet = SpreadsheetApp.getActive().getSheetByName('msia_else');
  else if(product_id =='8108 ')
  sheet = SpreadsheetApp.getActive().getSheetByName('msia_else');

  else
  sheet = SpreadsheetApp.getActive().getSheetByName('msia');
  else //if (currency == 'THB')
  sheet = SpreadsheetApp.getActive().getSheetByName('thai');

  if (order_status == "pending") return '';



 sheet.appendRow([order_number,order_created,order_status,billing_name,username,billing_email,billing_phone,billing_country,city,billing_address,shipping_address,shipping_post_code,payment_method,product_name,shipping_total,product_qty,product_total,total_amount,remaining_amount,coupon_name,payment_plan,next_payment,next_payment_date,product_id,variation_id]);

}

有人可以帮我吗？我正在尝试获取多个产品名称和产品 ID，但我没有使用上面的代码。我做错了什么
