How to generate a pre-filled form URL for Google F

问题:

I'm looking for a programmatic way to automate the generation of pre-filled URLs for google forms.

In a recent update, Google introduced a new Forms product to Google Docs. If you open the tools menu in a spreadsheet, you'll see some new options.

In the new Form Responses menu, one option is "Get pre-filled URL". This opens up a dialog containing a version of your form that you can fill out, and when you submit it, you receive a URL that can be used to open a Live Form with the data you pre-filled ready and waiting for you. The URL looks something like this...

https://docs.google.com/forms/d/--Form-ID--/viewform?entry.1094330118=Something&entry.1471717973=[e-mail]&entry.540962741&entry.787941281&entry.1873343651

The questions from the form have a fixed identity, e.g. entry.1094330118. They may be pre-filled with a value (entry.1094330118=Something) or blank (entry.7879412).

In apps-script, I'd like to generate these pre-filled URLs for users of my form, so I can provide them for updates. My users are not members of an Apps Domain, so I don't have the option of embedding an Edit your response link.

If I can get the information about the form, I will be able to piece together the URL. While I can go through the UI to create one URL, and dissect it to get the info for that form, I want a solution that will work with arbitrary forms.

1. How can I programmatically determine the question IDs?
2. With the new Forms product, is the form available to me through any apps-script APIs? (I know about getFormURL() - that's not what I mean.)
3. Armed with a question ID, can I get more information about the question? (Question text, type, etc.)

I required something similar for users to go and edit their response, take a look here: http://productforums.google.com/forum/#!topic/docs/LSKKCR3VHC8

Copy / paste code below:

function assignEditUrls() {
var form = FormApp.openById('1MonO-uooYhARHsr0xxxxxxxxxxxxxxxxxxxxx');
//enter form ID here

  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Form Responses');

    //Change the sheet name as appropriate
  var data = sheet.getDataRange().getValues();
  var urlCol = 4; // column number where URL's should be populated; A = 1, B = 2 etc
  var responses = form.getResponses();
  var timestamps = [], urls = [], resultUrls = [];

  for (var i = 0; i < responses.length; i++) {
    timestamps.push(responses[i].getTimestamp().setMilliseconds(0));
    urls.push(responses[i].getEditResponseUrl());
  }
  for (var j = 1; j < data.length; j++) {

    resultUrls.push([data[j][0]?urls[timestamps.indexOf(data[j][0].setMilliseconds(0))]:'']);
  }
  sheet.getRange(2, urlCol, resultUrls.length).setValues(resultUrls);  
}
