Google表格脚本通过电子邮件发送至PDF突然发送了损坏的PDF

如何解决Google表格脚本通过电子邮件发送至PDF突然发送了损坏的PDF

我有一个Google表格脚本，可以将页面以PDF格式发送到电子邮件，直到昨天为止，它一直运行良好。突然，它开始发送无法打开的损坏的PDF。

如果脚本无法打开PDF文件，并且显示“无法显示-无效格式”，则脚本运行良好。

关于它为何可能停止工作的任何想法？

function sendSheetToPdfwithA1MailAdress(){ // this is the function to call
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sh = ss.getSheets()[0]; // it will send sheet 0 which is the first sheet in the spreadsheet.
  // if you change the number,change it also in the parameters below
  var shName = sh.getName()
    
  // This function uses a cell in the spreadsheet that names the file that is being saved as getfilename().  using this function will pull from a certain Cell (G4 in this case)
function getFilename() {

    var spreadsheet = SpreadsheetApp.getActive();

    var sheet = spreadsheet.getSheetByName('N1944E'); // Edit the sheet name as necessary

    var cell = sheet.getRange('C8'); //Cell to pull file name from.
    var filename = cell.getValue();

    return filename;
} 

  sendSpreadsheetToPdf(0,shName,sh.getRange('C6').getValue(),"Air Attack Daily Fire Sheet " + getFilename() );
}
function sendSpreadsheetToPdf(sheetNumber,pdfName,email,subject,htmlbody) {
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  var spreadsheetId = spreadsheet.getId()  
  var sheetId = sheetNumber ? spreadsheet.getSheets()[sheetNumber].getSheetId() : null;  
 var url_base = spreadsheet.getUrl().replace(/edit$/,'');



  var url_ext = 'export?exportFormat=pdf&format=pdf'   //export as pdf

      + (sheetId ? ('&gid=' + sheetId) : ('&id=' + spreadsheetId)) 
      // following parameters are optional...
      + '&size=A4'      // paper size
      + '&portrait=true'    // orientation,false for landscape
      + '&fitw=true'        // fit to width,false for actual size
      + '&sheetnames=true&printtitle=false&pagenumbers=true'  //hide optional headers and footers
      + '&gridlines=false'  // hide gridlines
      + '&fzr=false';       // do not repeat row headers (frozen rows) on each page

  var options = {
    headers: {
      'Authorization': 'Bearer ' +  ScriptApp.getOAuthToken(),}
  }

  var response = UrlFetchApp.fetch(url_base + url_ext,options);
  var blob = response.getBlob().setName(pdfName + '.pdf');
  if (email) {
    var mailOptions = {
      attachments:blob,htmlBody:htmlbody
    }
MailApp.sendEmail(
      email,subject+" (" + pdfName +")","html content only",mailOptions);

MailApp.sendEmail(
      Session.getActiveUser().getEmail()," "+subject+" (" + pdfName +")",mailOptions);
  }
}

解决方法

我遇到了完全相同的问题，但是我只是想通了。问题在这里：

var url_base = ss.getUrl().replace(/edit$/,'') + "export?";

getUrl（）似乎返回的URL版本与以前不同。现在，它将以下内容附加在url上：“ ouid = ############＆urlBuilderDomain = YOURDOMAIN”使用记录器自己检查一下。

这导致pdf导出出现问题。因此，我用以下内容替换了该行，从而建立了自己的网址：

var url_base = "https://docs.google.com/spreadsheets/d/" + ss.getId() + "/" + "export?";

它现在似乎正在工作！这是生成我的Blob的完整代码：

function generatePDF(pdfName,sheet,portrait){
  var token = ScriptApp.getOAuthToken();
  var params = {
    headers: {
      'Authorization': 'Bearer ' + token,},'muteHttpExceptions' : true
  };
  
  var sheetId = sheet.getSheetId();
  var ss = sheet.getParent();
  
  
//  var url_base = ss.getUrl().replace(/edit$/,'') + "export?";
  var url_base = "https://docs.google.com/spreadsheets/d/" + ss.getId() + "/" + "export?";
  
  var url_ext = 'exportFormat=pdf'   //export as pdf
  + '&format=pdf'     //export as pdf
  + '&gid=' + sheetId
  + '&size=letter'      // paper size
  + '&portrait=' + portrait    // orientation,false for landscape
  + '&fitw=true'        // fit to width,false for actual size
  + '&sheetnames=false'  //optional headers and footers
  + '&printtitle=false'  //optional headers and footers
  + '&pagenumbers=true'  //page numbers
  + '&gridlines=true'  // gridlines
  + '&fzr=true'       // repeat row headers (frozen rows) on each page
  
  var response = UrlFetchApp.fetch(url_base + url_ext,params);
  var blob = response.getBlob().setName(pdfName + ".pdf");
  
  return blob;
}

,

尝试一下：

function sendSpreadsheetToPdf(sheetNumber,pdfName,email,subject,htmlbody) {
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  var spreadsheetId = spreadsheet.getId()  
  var sheetId = sheetNumber ? spreadsheet.getSheets()[sheetNumber].getSheetId() : null;  
  var url_base = "docs.google.com/spreadsheets/d" + spreadsheetId + "/export?";
  var url_ext = 'exportFormat=pdf&format=pdf'   //export as pdf
  
  + (sheetId ? ('&gid=' + sheetId) : ('&id=' + spreadsheetId)) 
  // following parameters are optional...
  + '&size=A4'      // paper size
  + '&portrait=true'    // orientation,false for actual size
  + '&sheetnames=true&printtitle=false&pagenumbers=true'  //hide optional headers and footers
  + '&gridlines=false'  // hide gridlines
  + '&fzr=false';       // do not repeat row headers (frozen rows) on each page
  
  var options = {
    headers: {
      'Authorization': 'Bearer ' + ScriptApp.getOAuthToken(),'muteHttpExceptions' : true
  }
  
  var response = UrlFetchApp.fetch(url_base + url_ext,options);
  var blob = response.getBlob().setName(pdfName + '.pdf');
  if (email) {
    var mailOptions = {
      attachments:blob,htmlBody:htmlbody
    }
    MailApp.sendEmail(
      email,subject+" (" + pdfName +")","html content only",mailOptions);
    
    MailApp.sendEmail(
      Session.getActiveUser().getEmail()," "+subject+" (" + pdfName +")",mailOptions);
  }
}

您可以尝试使用它代替当前的blob声明吗？

var blob = response.getBlob().getAs('application/pdf').setName(pdfName + ' .pdf');
