如何通过电子邮件发送内容以 table 格式显示的 PDF？

How to send a PDF via email with the contents displayed in table like format?

这是我现在使用的代码：

function emailQuestionnaireAsPDF(questionnaireKey) {
  if (app.getActiveUserRoles().indexOf(app.roles.Admins) === -1) {
    throw new Error('You don\'t have permissions to perform this operation');
  }

  var questionnaire = app.models.Questionnaire.getRecord(questionnaireKey);

  if (!questionnaire) {
    throw new Error('Questionnaire was not found');
  }

  var tmpDoc = DocumentApp.create(FILE_NAME + ' ' + Date.now());
  var body = tmpDoc.getBody();
  var title = questionnaire.FirstName + '\'s Questionnaire';
  var fields = app.metadata.models.Questionnaire.fields;

  body.insertParagraph(0, title)
    .setHeading(DocumentApp.ParagraphHeading.HEADING1)
    .setAlignment(DocumentApp.HorizontalAlignment.CENTER);

  appendField_(body, fields.FirstName.displayName,
               questionnaire.FirstName);
  appendField_(body, fields.LastName.displayName,
               questionnaire.LastName);
  appendField_(body, fields.LikeIceCream.displayName,
               questionnaire.LikeIceCream);
  appendField_(body, fields.FavoriteMovie.displayName,
               questionnaire.FavoriteMovie);
  appendField_(body, fields.FavoriteColor.displayName,
               questionnaire.FavoriteColor);
  appendField_(body, fields.LuckyNumber.displayName,
               questionnaire.LuckyNumber);

  tmpDoc.saveAndClose();

  var blob = tmpDoc.getAs(MimeType.PDF);
  var pdfFile = DriveApp.createFile(blob);

  Drive.Files.remove(tmpDoc.getId());
  pdfFile.setName(FILE_NAME);

  sendEmail_(Session.getActiveUser().getEmail(), FILE_NAME, pdfFile.getUrl());
}

我正在尝试将与调查问卷相关的模型中的所有字段附加到 "pdfFile"。这是如何以一种方式完成的，所有关联的字段和值都以类似 table 的格式粘贴到 pdfFile 中？

根据您的描述，我是这样做的：

  1. 创建了一个名为 问卷 的模型，其中包含以下字段：

    • 名字
    • 姓氏
    • 喜欢冰淇淋
    • 最喜欢的电影
    • 最喜欢的颜色
    • 幸运数

我添加了一些测试记录。然后在服务器脚本上我添加了两个函数。第一个发送电子邮件的人如下所示：

function sendEmail(recipient, fileUrl, fileName){

  var pdfBlob = UrlFetchApp.fetch(fileUrl).getAs("application/pdf");

  MailApp.sendEmail({
    to: recipient,
    subject: "PDF Email Sample",
    htmlBody: "Attached the PDF File",
    attachments: [pdfBlob]
  });  

}

生成文档的第二个函数如下所示：

function emailQuestionnaireAsPDF(questionnaireKey){

  if (app.getActiveUserRoles().indexOf(app.roles.Admins) === -1) {
    throw new Error('You don\'t have permissions to perform this operation');
  }

  var questionnaire = app.models.questionnaire.getRecord(questionnaireKey);

  if (!questionnaire) {
    throw new Error('Questionnaire was not found');
  }

  //Start generating the HTML template
  var htmlData = "";
  htmlData += "<h1 style='text-align:center'>" + questionnaire.firstName + "'s Questionnaire </h1><br>"; //Title of the document

  //Create table start tag
  htmlData += "<table style='border:none;'>";

  //Create headers and append to table
  var headers = ["QUESTION", "RESPONSE"];
  var hRowStyle = "background-color:#efefef"; //style for table header row
  var hCellStyle = "font-weight:bold; padding-top:4px; padding-bottom: 3px; border-bottom:1px solid #bebebe;"; //style for table header cells
  htmlData += "<tr style='"+hRowStyle+"'><td style='"+hCellStyle+"'>" + headers.join("</td><td style='"+hCellStyle+"'>") + "</td></tr>";

  //Define row cell styles
  var tdSytle = "border-bottom: 1px solid #bebebe; border-left:0px; border-right:0px; padding-top:7px; padding-bottom: 6px;";

  //Create table rows
  var rows = [];
  rows.push(["First Name:", questionnaire.firstName]); // Add firstName
  rows.push(["Last Name:", questionnaire.lastName]); // Add lastName
  rows.push(["Likes Icecream:", questionnaire.likeIcecream]); // Add likeIceacream
  rows.push(["Favorite Movie:", questionnaire.favoriteMovie]); // Add favoriteMovie
  rows.push(["Favorite Color:", questionnaire.favoriteColor]); // Add favoriteColor
  rows.push(["Lucky Number:", questionnaire.luckyNumber]); // Add luckyNumber

  //Append rows to table
  rows.forEach(function(row){
     htmlData += "<tr><td style='"+tdSytle+"'>" + row.join("</td><td style='"+tdSytle+"'>") + "</td><tr>";
  });

  //Create table end tag
  htmlData += "</table>";

  //Create gooleDriveDoc
  var fileName = questionnaire.firstName + "'s Questionnaire";
  var data = Utilities.newBlob("").setDataFromString(htmlData).setContentType("text/html");
  var drvFile = Drive.Files.insert({title: fileName}, data, {convert: true});

  //Mail PDF File
  var recipient = "email@test.com";
  var fileUrl = "https://docs.google.com/document/d/"+drvFile.id+"/export?format=pdf&access_token="+ScriptApp.getOAuthToken();  
  sendEmail(recipient, fileUrl, fileName);

}

总而言之，我从 HTML 模板创建了一个 google 文档。然后，我使用带有访问令牌的下载 url 来获取 pdf Blob 并将其附加到电子邮件中。

结果如下：

通读代码，您应该能够详细了解它正在做什么，当然，您可以改进它！
