Question

我有一个部署为Web App的独立脚本。我的代码完全像Web应用程序一样工作。但是，我的目标是在电子表格项目中使用该代码。

我将代码复制并粘贴到电子表格脚本中并进行了一些更改，使其在弹出式模态对话框窗口中工作，但它不像部署的Web应用程序那样工作。代码似乎没有向Code.gs返回任何数据。在代码路径上的各个点运行警报后，我发现了故障点，但我不确定如何解决它。

来自正在运行的WebApp的代码（2个文件：Code.gs＆amp; form.html）：

## Code.gs file ##
function doGet() {
  return HtmlService.createHtmlOutputFromFile('form')
    .setSandboxMode(HtmlService.SandboxMode.IFRAME);
}

function uploadFileToDrive(base64Data, fileName, totalFiles, finalCount) {
  try{
    var splitBase = base64Data.split(','),
        type = splitBase[0].split(';')[0].replace('data:','');

    var byteCharacters = Utilities.base64Decode(splitBase[1]);
    var ss = Utilities.newBlob(byteCharacters, type);
    ss.setName(fileName);

    var dropbox = "stuff"; // Folder Name
    var folder, folders = DriveApp.getFoldersByName(dropbox); // Get folders by name

    if (folders.hasNext()) {
      folder = folders.next();
    } else {
      folder = DriveApp.createFolder(dropbox);
    }
    var file  = folder.createFile(ss);

    // BEGIN LOGGING FILE NAMES AND IDs
    var dropboxId = "SOME_FOLDER_ID_HERE" // Folder ID
    var theFolder = DriveApp.getFolderById(dropboxId); // Get folder by ID
    var list     = [];
    var theBlobs = [];
    if (totalFiles == finalCount) {
      var files = theFolder.getFiles();
      while (files.hasNext()) {
        var theFile = files.next();
        list.push(theFile.getId());
      }
      for (var i = 0; i < list.length; i++) {
        Logger.log(DriveApp.getFileById(list[i]).getName() + " : " + list[i]);
        theBlobs.push(DriveApp.getFileById(list[i]).getBlob());
      }
      Logger.log(theBlobs);
      // END LOGGING FILE NAMES AND IDs


      // BEGIN ZIPPING UP FILES
        var newZip = theFolder.createFile(Utilities.zip(theBlobs, 'zippedFiles.zip'));

此时非工作代码停止： google.script.run.withSuccessHandler(updateProgressbar).uploadFileToDrive(content, file.name, totalFiles, newCount);。

到目前为止，一切都很顺利，信息从一个函数传递到另一个函数。

在电子表格脚本中，文件永远不会上传到云端硬盘，并且html页面上显示的文件的计数器永远不会增加...它只会停止。

我所遇到的可能有助于解决这个问题的最接近的文章是：how to use google.script.run as if it was a function最初被提议作为此问题的解决方案Google Apps Script HTML Service: Passing variables和Returning a value using Date picker in HTMLService / Google Apps Script。

提前感谢您的帮助!!

解决方案非常简单，因为底层代码已经作为独立的Web应用程序运行。

所需的唯一更改是Code.gs文件。

拉出代码的开头并将其保存在自己的顶层函数中：

function uploadFiles() {

  function doGet() {
    return SpreadsheetApp.getUi().showModalDialog(HtmlService.createHtmlOutputFromFile('form').setSandboxMode(HtmlService.SandboxMode.IFRAME), "Upload Files");
  }

  doGet();
}

然后将余数放在它自己的顶级函数中：

function uploadFileToDrive(base64Data, fileName, totalFiles, finalCount) {
  try{
    var splitBase = base64Data.split(','),
    type = splitBase[0].split(';')[0].replace('data:','');

    var byteCharacters = Utilities.base64Decode(splitBase[1]);
    var ss = Utilities.newBlob(byteCharacters, type);
    ss.setName(fileName);

    var dropbox = "stuff"; // Folder Name
    var folder, folders = DriveApp.getFoldersByName(dropbox); // Get folders by name

    if (folders.hasNext()) {
      folder = folders.next();
    } else {
      folder = DriveApp.createFolder(dropbox);
    }
    var file  = folder.createFile(ss);

    // BEGIN LOGGING FILE NAMES AND IDs
    var dropboxId = "SOME_FOLDER_ID_HERE" // Folder ID
    var theFolder = DriveApp.getFolderById(dropboxId); // Get folder by ID
    var list     = [];
    var theBlobs = [];
    if (totalFiles == finalCount) {
      var files = theFolder.getFiles();
      while (files.hasNext()) {
        var theFile = files.next();
        list.push(theFile.getId());
      }
      for (var i = 0; i < list.length; i++) {
        Logger.log(DriveApp.getFileById(list[i]).getName() + " : " + list[i]);
        theBlobs.push(DriveApp.getFileById(list[i]).getBlob());
      }
      Logger.log(theBlobs);
      // END LOGGING FILE NAMES AND IDs


      // BEGIN ZIPPING UP FILES
        var newZip = theFolder.createFile(Utilities.zip(theBlobs, 'zippedFiles.zip'));
        var zipId  = newZip.getId();
        Logger.log("Zip Id: " + zipId);
      // END ZIPPING UP FILES


      // BEGIN TRASHING UPLOADED FILES
      for (var i = 0; i < list.length; i++) {
        DriveApp.getFileById(list[i]).setTrashed(true);
      }
      // END TRASHING UPLOADED FILES
    }

    return file.getName();
  }catch(e){
    return 'Error: ' + e.toString();
  }
}

它现在可以完美地作为附加到电子表格的脚本！

Google Apps脚本可用作Web应用但不是电子表格脚本
