从 Google 电子表格接收实时更新

Question

我正在尝试使用 Google 电子表格设置双向同步。我可以使用 Google Sheets API V4

将数据集中的更改推送到 Google 电子表格

现在，我希望能够在有人实时或近乎实时地编辑或添加新行时从 Google 电子表格中获取更新。

非常感谢为我指明正确方向的任何帮助。

您可以通过转到工具-> 通知规则手动执行此操作..

如果文件在Google盘，你可以尝试使用Push Notifications： 要使用推送通知，您需要做三件事：

Register the domain of your receiving URL. For example, if you plan to use //mydomain.com/notifications as your receiving URL, you need to register //mydomain.com. Set up your receiving URL, or "Webhook" callback receiver. This is an HTTPS server that handles the API notification messages that are triggered when a resource changes. Set up a notification channel for each resource endpoint you want to watch. A channel specifies routing information for notification messages. As part of the channel setup, you identify the specific URL where you want to receive notifications. Whenever a channel's resource changes, the Drive API sends a notification message as a POST request to that URL.

您也可以使用 Appscript。这个简单的技巧来自 SO thread:

var sheet = **whatever**;//The spreadsheet where you will be making changes
var range = **whatever**;//The range that you will be checking for changes
var compSheet = **whatever**;//The sheet that you will compare with for changes
function checkMatch(){
  var myCurrent = sheet.getRange(range).getValues();
  var myComparison = compSheet.getRange(range).getvalues();
  if(myCurrent == myComparison){//Checks to see if there are any differences
    for(i=0;i<compSheet.length;++i){ //Since getValues returns a 'multi-dimensional' array, 2 for loops are used to compare each element
     for(j=0;j<compSheet[i].length;++i){
      if(myCurrent[i][j] != myComparison[i][j]){//Determines if there is a difference;
       //***Whatever you want to do with the differences, put them here***
     }
    }

    myEmailer(sheet.getUrl());//Passes the url of sheet to youur emailer function 
    compSheet.getRange(range).setValues(myCurrent);//Updates compSheet so that next time is can check for the next series of changes
    }
  }
