如何修剪 Google Apps 脚本输出

Question

我正在 Flutter 中“开发”一个移动应用程序，该应用程序必须通过 httpService 获取 json 进行解析。我对 Flutter 如何解析 json 文件、重新配置我的应用程序的方法和/或功能、允许它使用我的 Google App Script 当前输出的内容知之甚少；而且我对 Google App Scripts 的了解不够，无法修改该代码，以便它为 Flutter 应用程序提供所需的格式。但似乎做一个或另一个可以解决我的问题。

具体来说，我的 Flutter 应用需要一个如下所示的 json：

[
{   "userId":"My Category Kittens","id":"Black","title":"Solid","body":"10"},
{   "userId":"My Category Kittens","id":"White","title":"Striped","body":"20"},
{   "userId":"My Category Kittens","id":"Gray","title":"Spotted","body":"30"},
{   "userId":"My Category Puppies","id":"Brown","title":"Shaggy","body":"40"},
{   "userId":"My Category Puppies","id":"Blue","title":"Scruffy","body":"50"},
{   "userId":"My Category Puppies","id":"Orange","title":"Mangey","body":"60"},
{   "userId":"My Category Puppies","id":"Pink","title":"Fluffy","body":"70"},
{   "userId":"My Category Birdies","id":"Green","title":"Slick","body":"80"},
{   "userId":"My Category Birdies","id":"Yellow","title":"Pixeled","body":"90"},
{   "userId":"My Category Birdies","id":"Purple","title":"Plaid","body":"100"},
{   "userId":"My Category Birdies","id":"Transparent","title":"Argiled","body":"110"},
{   "userId":"My Category Birdies","id":"Utraviolet","title":"Bald","body":"120"}
]

但我的 Google Apps 脚本会生成这个：

{"user":[
{   "userId":"My Category Kittens","id":"Black","title":"Solid","body":"10"},
{   "userId":"My Category Kittens","id":"White","title":"Striped","body":"20"},
{   "userId":"My Category Kittens","id":"Gray","title":"Spotted","body":"30"},
{   "userId":"My Category Puppies","id":"Brown","title":"Shaggy","body":"40"},
{   "userId":"My Category Puppies","id":"Blue","title":"Scruffy","body":"50"},
{   "userId":"My Category Puppies","id":"Orange","title":"Mangey","body":"60"},
{   "userId":"My Category Puppies","id":"Pink","title":"Fluffy","body":"70"},
{   "userId":"My Category Birdies","id":"Green","title":"Slick","body":"80"},
{   "userId":"My Category Birdies","id":"Yellow","title":"Pixeled","body":"90"},
{   "userId":"My Category Birdies","id":"Purple","title":"Plaid","body":"100"},
{   "userId":"My Category Birdies","id":"Transparent","title":"Argiled","body":"110"},
{   "userId":"My Category Birdies","id":"Utraviolet","title":"Bald","body":"120"}
]}

那么，对于编辑我的 Google Apps 脚本以省略前导 '{"user":' 和结尾的 '}' 有什么建议吗？

这是我的 Google 应用脚本代码：

function doGet(e){

 // Spread Sheet url
 var ss = SpreadsheetApp.openByUrl("https://docs.google.com/spreadsheets/d/1jsBS-RBNRxYU66WFkJHvrzHLGmNqxBzzQfaHJO6i6UY/edit#gid=446843772");

// Sheet Name
 var sheet = ss.getSheetByName("Users");

 return getUsers(sheet); 

}


function getUsers(sheet){
  var jo = {};
  var dataArray = [];

// collecting data from 2nd Row , 1st column to last row and last column
  var rows = sheet.getRange(2,1,sheet.getLastRow()-1, sheet.getLastColumn()).getValues();

  for(var i = 0, l= rows.length; i<l ; i++){
    var dataRow = rows[i];
    var record = {};
    record['userId'] = dataRow[0];
    record['id'] = dataRow[1];
    record['title'] = dataRow[2];
    record['body'] = dataRow[3];

    dataArray.push(record);

  }  

  jo.user = dataArray;

  var result = JSON.stringify(jo);

  return ContentService.createTextOutput(result).setMimeType(ContentService.MimeType.JSON);

}

非常感谢任何帮助！ 谢谢

当我看到你的脚本时，dataArray 被jo.user = dataArray; 放到了user 的属性中。这样，result 就是{"user":[]dataArray}。

作为解决问题的简单修改，请如下修改并测试。

发件人：

jo.user = dataArray;

收件人：

jo = dataArray;

由此，result 只是 dataArray。

注意：

• 您似乎正在使用 Web 应用程序。因此，请在修改脚本时将 Web 应用程序重新部署为新版本。这样，最新的脚本就会反映到 Web 应用程序中。请注意这一点。
