这是How to Use Advanced Drive Service to Upload Files的延续。

我的Webapp包含数据文件的上传表单，然后存储在Google云端硬盘中。（下面的代码段中的完整代码。）我遇到以下代码行的问题：

    var file = Drive.Files.insert(resource, mediaData); // create file using Drive API

＆＃13;

    try {  
      
        //Get root folder and pull all existing folders, plus setup variables pulled from form   
        var dropbox = form.Country;
        var timeStamp = new Date();      
        
        //Set file name slightly differently for Weekly Member Report (do not want to overright based on name just keep each extract so add timestamp to name)
        if (form.reportType == "Member Weekly"){
          var filename = form.reportType + timeStamp + ".xls";
        }
        else 
        {
        var filename = form.reportType+".xls";
        }
      
        var rootfolder = DriveApp.getFolderById("0Byvtwn42HsoxfnVoSjB2NWprYnRiQ2VWUDZEendNOWwwM1FOZk1EVnJOU3BxQXhwU0pDSE0");
        //Note root folder is Live Uploads Folder in Flatworld App folder structure
        var folder, folders = rootfolder.getFoldersByName(dropbox);
        
        //Check if folder exists and if not create    
        if (folders.hasNext()) {
          folder = folders.next();
        } else {
          folder = rootfolder.createFolder(dropbox);
        }
      
        var FolderURL = folder.getUrl(); // Retain URL of folder for final end message to user
      
        //Check if file already exists and delete if it does
        var file, files = folder.getFilesByName(filename);
        while( files.hasNext()){
          file = files.next();
          file.setTrashed(true);
        }
        
      //New Code from Stackover Flow:
      
      //Upload file and set various properties
      var mediaData = form.myFile;    
      var resource = {
        title: filename,
        mimetype: 'application/vnd.ms-excel',
        description: "Uploaded via BNI Upload Form by " + form.myName + " on: " + timeStamp
      };
      var file = Drive.Files.insert(resource, mediaData); // create file using Drive API
      var fileId = file.id;
      var DriveAppFile = DriveApp.getFileById(fileId); // retrieve file in DriveApp scope.
      var FileURL = DriveAppFile.getUrl(); //Retain URL of file for final end message to user
      
      DriveApp.removeFile(DriveAppFile); // remove new file from Users root My Drive
      folder.addFile(DriveAppFile); // puts file in selected folder
      
      
      //End of New code from Stackover Flow
       
        //Success message displayed to user    
      return "Thanks! File uploaded successfully to: <br><br><b>Folder Location:</b> " + FolderURL + "<br>" + "<b>File:</b> " + FileURL + ". <br><br>For any queries please email user@example.com copying the URLs displayed here in your email. You can close this browser window now or use the link below to upload another file.<br><br>";
        
      } catch (error) {
        
        //Catch error return it to user and email with error details

抛出错误消息＆＃34;空响应＆＃34;在我们尝试上传大文件时，在上面的代码行（15MB）你有什么建议吗？这完全在文件插入限制5120GB内，并且代码在较小的文件上正常工作。

我现在试图添加一个循环函数来尝试上传几次，但仍然遗憾地抛出同样的错误：

＆＃13;

  //setup function that will return null if file is not uploaded correctly
  function createDriveFile(resource_f, mediaData_f){
    try{ 
      var file = Drive.Files.insert(resource_f, mediaData_f); // create file using Drive API
      return file;
    } catch (e) {return null;}
  }
  
  
  //try upload and loop if null
  var maxTries = 3;
  var tries = 0;
  do {
    tries = tries + 1;
    if (tries > 0) {
     var file = createDriveFile(resource, mediaData);
     Logger.log("I'm trying to upload, try number: " + tries);
    }
  } while ((file == null) && (tries < maxTries));
  if (file == null) {
  var file = Drive.Files.insert(resource, mediaData); // try one laste time to create file using Drive API - outside loop function so if error is thrown script stops
  }

＆＃13;

错误似乎只发生在较大的文件上，即使我们减少了解决错误的同一文件的大小，因此我们需要调整上传过程以考虑更大的文件。是否有Google Apps脚本相当于制作API upload request resumable？

Answer 1

您的文件大小是决定因素。参考文档表明，此处使用的简单上传方法仅适用于5MB。

https://developers.google.com/drive/web/manage-uploads

您的评论似乎证实了这就是您正在发生的事情。

正如您所暗示的那样，请使用可恢复的上传方法。使用uploadType: resumable参数标记 - API docs on the insert method描述了如何。

Answer 2

您还可以检查文件的命名，对我来说，我的名称中有一个斜线，这就是为什么它不上传的原因。因此，在上传之前请删除所有特殊字符，它应该可以工作。
