用于从 Gmail 中提取数据并在 Google 表格中填写多个匹配行的 Google Apps 脚本

Question

从Google Apps Script to extract data from Gmail and fill in matching row in Google Sheets 开始，还有另一封电子邮件，其中包含在一封电子邮件中的多个跟踪号。示例...

Your order is ready to be redeemed/ delivered. 
Order No. 91401111 
Tracking No. (Actual Weight／Chargeable Weight) JK5SD8F4M6 (2.1lb) 
J6HDO9L665 (2.1lb) 
J3SDG76435 (9.8lb) 
Courier UPS
Shipment No. 23879924905

我想提取电子邮件中的数据并填写正确的单元格，例如这样...

目前脚本是这样的……

function extractDetails(message){

  var emailData = {
    body: "Null",
    trackingno: "Null",
    weight: "Null",
    orderno: "Null",
    courier: "Null",
    shipmentno: "Null"
  }

  emailData.body = message.getPlainBody();
  emailData.trackingno = emailData.body.match(/(?<=Tracking No. \(Actual Weight／Chargeable Weight\) ).*/).toString().trim();
  emailData.weight = emailData.body.match(/????????/).toString().trim();
  emailData.orderno = emailData.body.match(/(?<=Order No. ).*/).toString().trim();
  emailData.courier = emailData.body.match(/(?<=Courier ).*/).toString().trim();
  emailData.shipmentno = emailData.body.match(/(?<=Shipment No. ).*/).toString().trim();

  var activeSheet = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = activeSheet.getSheetByName('Sheet1');
  var range = sheet.getRange("A2:A" + sheet.getLastRow()).createTextFinder(emailData.trackingno).findNext();

  if (range) {
    range.offset(0, 3).setValue(emailData.weight);
    range.offset(0, 4).setValue(emailData.orderno);
    range.offset(0, 5).setValue(emailData.courier);
    range.offset(0, 6).setValue(emailData.shipmentno);
  } else {
    sheet.appendRow([emailData.trackingno, '', '', emailData.weight, emailData.orderno, emailData.courier, emailData.shipmentno]);
  }
}

我知道上述脚本中几乎没有错误。首先，我不知道如何编写正则表达式来找到权重。然后，我不知道如何提取所有跟踪号。我可能应该将提取的跟踪号存储在一个数组中，然后使用 for 循环进行匹配。请帮忙。谢谢。

我相信你的目标如下。

• 您想从以下文本中检索 Order No、Courier、Shipment No、Parcel Weight 和 Tracking No 的值。

    Your order is ready to be redeemed/ delivered. 
    Order No. 91401111 
    Tracking No. (Actual Weight／Chargeable Weight) JK5SD8F4M6 (2.1lb) 
    J6HDO9L665 (2.1lb) 
    J3SDG76435 (9.8lb) 
    Courier UPS
    Shipment No. 23879924905
  

• 您想通过搜索跟踪编号将值放入电子表格。

• 您希望使用 Google Apps 脚本实现此目的。

在这种情况下，下面的示例脚本怎么样？在这种情况下，我使用您的示例文本来测试脚本。

示例脚本：

我认为在您的脚本中，我的示例脚本中的text 与emailData.body 相同。

function myFunction(){
  // This text is from your question.
  const text = `Your order is ready to be redeemed/ delivered. 
Order No. 91401111 
Tracking No. (Actual Weight／Chargeable Weight) JK5SD8F4M6 (2.1lb) 
J6HDO9L665 (2.1lb) 
J3SDG76435 (9.8lb) 
Courier UPS
Shipment No. 23879924905`;

  // 1. Retrieve each value you want to retrieve.
  const obj1 = text.split("\n").reduce((o, e) => {
    const regex = new RegExp("([A-Z0-9]+) \\(([0-9.]+)lb\\)");
    if (e.includes("Order")) {
      o.orderNo = Number(e.trim().split(" ").pop());
    } else if (e.includes("Courier")) {
      const t = e.trim().split(" ");  // Modified
      t.shift();  // Modified
      o.courier = t.join(" ");  // Modified
    } else if (e.includes("Shipment")) {
      o.shipmentNo = Number(e.trim().split(" ").pop());
    } else if (regex.test(e)) {
      const [, trackingNo, parcelNo] = e.match(regex);
      o.trackingNo.push({trackingNo: trackingNo, parcelNo: parcelNo});
    }
    return o;
  }, {orderNo: "", courier: "", shipmentNo: "", trackingNo: []});

  // 2. Create an object for searching tracking No.
  const obj2 = obj1.trackingNo.reduce((o, {trackingNo, parcelNo}) => Object.assign(o, {[trackingNo]: [parcelNo, obj1.orderNo, obj1.courier, obj1.shipmentNo]}), {});

  // 3. Retrieve existing values from Spreadsheet and creating new values for putting to Spreadsheet.
  var activeSheet = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = activeSheet.getSheetByName('Sheet1');
  var range = sheet.getRange("A2:G" + sheet.getLastRow());
  var newValues = range.getValues().map(([a, b, c, ...efg]) => {  // Modified
    var temp = [];
    if (obj2[a]) {
      temp = [a, b, c, ...obj2[a]];
      delete obj2[a];
    } else {
      temp = [a, b, c, ...efg];  // Modified
    }
    return temp;
  });

  // 4. If the tracking No is not found, the values are appended to the last row.
  var tempAr = Object.entries(obj2);
  if (tempAr.length > 0) {
     newValues = newValues.concat(tempAr.map(([k, v]) => [k, "", "", ...v]));
  }

  // 5. Clear sheet and put the new values to the sheet.
  range.clearContent();
  sheet.getRange(2, 1, newValues.length, newValues[0].length).setValues(newValues);
}

注意：

• 在此示例脚本中，当您的文本与问题中的文本不同时，可能无法使用该脚本。所以请注意这一点。
