生成PDF成功,添加二维码失败

Generating PDF Succesfully but I failed when I added Qr Code

我有 google 表格,回复如下 table(电子表格)。

此脚本无法生成二维码。 header中的二维码公式,所以它会自动在电子表格中的B列中使用D.I列中的数据生成二维码不知道如何解决。

var docTemplate = "doc ID"; 
var docName = "Vehicle check with images";

function onFormSubmit(e) {
  var replaceTextToImage = function(body, searchText, fileId) {
    var width = 300; // Please set this.
    var blob = DriveApp.getFileById(fileId).getBlob();
    var r = body.findText(searchText).getElement();
    r.asText().setText("");
    var img = r.getParent().asParagraph().insertInlineImage(0, blob);
    var w = img.getWidth();
    var h = img.getHeight();
    img.setWidth(width);
    img.setHeight(width * h / w);
  }

  //Get information from form and set as variables
  var email_address = "myemailaddress@here.com";
  var qrCode = e.values[1].split("=")[3];//I want to try
  var empName = e.values[2];
  var empId = e.values[3];
  var photo = e.values[4].split("=")[1];

  // Get document template, copy it as a new temp doc, and save the Doc’s id
  var copyId = DriveApp.getFileById(docTemplate)
  .makeCopy(docName+' for '+empName)
  .getId();
  // Open the temporary document
  var copyDoc = DocumentApp.openById(copyId);
  // Get the document’s body section
  var copyBody = copyDoc.getBody();

  replaceTextToImage(copyBody, 'qrcode', qrCode);//problem could not be generated
  copyBody.replaceText('name', empName);
  copyBody.replaceText('id', empId);
  replaceTextToImage(copyBody, 'photo', photo);

  copyDoc.saveAndClose();
  var pdf = DriveApp.getFileById(copyId).getAs("application/pdf");
  var subject = "sample attachment file";
  var body = "sample text: " + empName + "";
  MailApp.sendEmail(email_address, subject, body, {htmlBody: body, attachments: pdf});

  DriveApp.getFileById(copyId).setTrashed(true);
}

Timestamp ={"QR CODE";ARRAYFORMULA(IF(D2:D<>"";IMAGE("https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl="&D2:D);))} Name Id Photo
10/07/2021 8:35:24 QR CODE Robert 1234 https://drive.google.com/open?id=14SAL5EK8tqOESgZyAayScbTqhSEE89Wa

我没能重现问题。我或多或少地重复了所有步骤,它按预期工作。这是最小的可重现示例。

const doc_template_ID = 'template ID';
const ss_ID = 'spreadsheet ID';
const email_address = 'mail@gmail.com';

function make_doc_and_send_it_as_pdf() {

  // get data from spreadsheet
  const sheet = SpreadsheetApp.openById(ss_ID).getSheets()[0];
  const QR_text = sheet.getRange('B1').getValue();

  // make copy of the template and make changes in the doc
  const doc_file = DriveApp.getFileById(doc_template_ID).makeCopy('QR_code');
  const doc_ID = doc_file.getId()
  const doc = DocumentApp.openById(doc_ID);
  var body = doc.getBody();
  body = body.replaceText('{{text}}', QR_text);

  // insert a pic of the QR code
  const url   = "https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=" + QR_text; 
  const resp  = UrlFetchApp.fetch(url);
  const image = resp.getBlob();
  replaceTextToImage(body, '{{QR}}', image);

  doc.saveAndClose();
  
  // send the doc via email as pdf
  var pdf = doc_file.getAs("application/pdf");
  var subject = "QR pdf";
  var body = "sample text";
  MailApp.sendEmail(email_address, subject, body, {htmlBody: body, attachments: pdf});

  doc_file.setTrashed(true);
}

// modified Tataike's function from here
// https://tanaikech.github.io/2018/08/20/replacing-text-to-image-for-google-document-using-google-apps-script/
// now it takes image (blob) instead of fileId

function replaceTextToImage(body, searchText, image) {
    var next = body.findText(searchText);
    if (!next) return;
    var r = next.getElement();
    r.asText().setText('');
    r.getParent().asParagraph().insertInlineImage(0, image);
    return next;
  };

我的电子表格如下所示:

我的文档模板如下所示:

电子邮件中的 PDF 格式如下:

它从电子表格中获取数据,复制文档模板,更改文档中的文本,在文档中插入二维码图像(它替换所有包含“{{QR}}”的段落,我离开了照原样,可能它只能替换段落中的一个词)),然后通过邮件将文档以 PDF 格式发送。


在您的代码中,您可能需要这样更改函数 replaceTextToImage()

var replaceTextToImage = function(body, searchText, blob) {
    var width = 300; // Please set this.
    var r = body.findText(searchText).getElement();
    r.asText().setText("");
    var img = r.getParent().asParagraph().insertInlineImage(0, blob);
    var w = img.getWidth();
    var h = img.getHeight();
    img.setWidth(width);
    img.setHeight(width * h / w);
  }

它使函数采用 blob 而不是 fileId

并更改这两行:

var qrCode = e.values[3].split("=")[1];
var photo = e.values[4].split("=")[1];

有了这个:

var qrCode = UrlFetchApp.fetch(e.values[3].split("=")[1]).getBlob();
var photo = DriveApp.getFileById(e.values[4].split("=")[1]).getBlob();

我假设e.values[3].split("=")[1]包含二维码文本,e.values[4].split("=")[1]包含文件ID。但我可能是错的。
