如何修复没有'Access-Control-Allow-Origin'标题出现'错误 [英] How to fix No 'Access-Control-Allow-Origin' header is present' error

问题描述

我正在编写程序，当我尝试提交数据时，我收到此错误，请求的资源上没有Access-Control-Allow-Origin标头。因此，不允许原点'null'访问。。此代码应该将数据从HTML表单发送到Google表格文档。我跟着文章的教程来创建它。

I am writing a program, and when I try to submit data I get this error, No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.. This code is supposed to send data from an HTML form to a Google Sheets document. I followed an article's tutorial to create it.

这是我的代码 JS ：

var $form = $('form#Send'),

url = 'https://script.google.com/macros/s/<script ID>/exec'

$('#submitit').on('click', function(e) {
  e.preventDefault();
  var jqxhr = $.ajax({
    url: url,
    method: "GET",
    dataType: "json",
    data: $form.serializeObject()
  });

这是我的Google脚本代码：

And here is my Google script code:

// original from: http://mashe.hawksey.info/2014/07/google-sheets-as-a-database-insert-with-apps-script-using-postget-methods-with-ajax-example/
// original gist: 
https://gist.github.com/willpatera/ee41ae374d3c9839c2d6 

function doGet(e){
  return handleResponse(e);
}

//  Enter sheet name where data is to be written below
var SHEET_NAME = "GAME_THING";

var SCRIPT_PROP = PropertiesService.getScriptProperties(); 
// new property service

function handleResponse(e) {
  // shortly after my original solution Google announced the LockService[1]
  // this prevents concurrent access overwritting data
  // [1] http://googleappsdeveloper.blogspot.co.uk/2011/10/concurrency-and-google-apps-script.html
  // we want a public lock, one that locks for all invocations
  var lock = LockService.getPublicLock();
  lock.waitLock(30000);  // wait 30 seconds before conceding defeat.

  try {
    // next set where we write the data - you could write to multiple/alternate destinations
    var doc = SpreadsheetApp.openById(SCRIPT_PROP.getProperty("key"));
    var sheet = doc.getSheetByName(SHEET_NAME);

    // we'll assume header is in row 1 but you can override with header_row in GET/POST data
    var headRow = e.parameter.header_row || 1;
    var headers = sheet.getRange(1, 1, 1, sheet.getLastColumn()).getValues()[0];
    var nextRow = sheet.getLastRow()+1; // get next row
    var row = []; 
    // loop through the header columns
    for (i in headers) {
      if (headers[i] == "Timestamp") { // special case if you include a 'Timestamp' column
        row.push(new Date());
      } else { // else use header name to get data
        row.push(e.parameter[headers[i]]);
      }
    }
    // more efficient to set values as [][] array than individually
    sheet.getRange(nextRow, 1, 1, row.length).setValues([row]);
    // return json success results
    return ContentService
      .createTextOutput(JSON.stringify({"result":"success", "row": nextRow}))
      .setMimeType(ContentService.MimeType.JSON);
  } catch(e) {
    // if error return this
    return ContentService
          .createTextOutput(JSON.stringify({"result":"error", "error": e}))
          .setMimeType(ContentService.MimeType.JSON);
  } finally { //release lock
    lock.releaseLock();
  }
}

function setup() {
    var doc = SpreadsheetApp.getActiveSpreadsheet();
    SCRIPT_PROP.setProperty("key", doc.getId());
}
