我编写了一个自定义的 Google 脚本,它为我输出一个对象,我希望能够调用它并将它分配给一个变量,然后用于在网站上显示数据。

}
});
});

谷歌脚本文件:
function doGet() {
var result = {};
var infected = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Data').getDataRange().getValues();
var death = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Data').getDataRange().getValues();
result = makeObject(infected);
return ContentService.createTextOutput(JSON.stringify(result)).setMimeType(ContentService.MimeType.JSON);
}
function makeObject(multiArr) {
var obj = {};
var countrystats = {};
var headers = multiArr.shift();
for (var i = 0; i < headers.length; i++) {
countrystats[i] = multiArr.map(function (app) {
return app[i];
})
}
for (var m = 0; m < countrystats[1].length; m++) {
obj[countrystats[1][m]] = 0;
}
for (var j = 0; j < countrystats[1].length; j++) {
var TempVar;
TempVar = obj[countrystats[1][j]];
obj[countrystats[1][j]] = TempVar + countrystats[3][j];
}
return obj;
}
谷歌脚本输出(使用 JSON View chrome 扩展):
{
cn: 8134,
th: 23,
mo: 7,
us: 5,
jp: 11,
kr: 4,
sg: 10,
vn: 2,
fr: 5,
np: 1,
my: 8,
ca: 3,
ci: 1,
lk: 1,
au: 9,
de: 4,
fn: 1
}
这是我想要的对象/数据的公共链接(上面显示的相同对象):网络应用程序: https ://script.google.com/macros/s/AKfycbzsyQNJwDvQc5SvNGEDZZOoNI3XxNar9PA9sRucZx7mgzfWpFQ/exec
所以基本上任何使用它的人都应该能够访问它。我只需要一种将数据分配给本地 JS 变量的方法。google 表格脚本作为网络应用程序发布。如果我没记错的话,有一个设置允许任何人,甚至匿名访问它。
这是我对 AJAX 请求的尝试:
var url = "https://script.google.com/macros/s/AKfycbzsyQNJwDvQc5SvNGEDZZOoNI3XxNar9PA9sRucZx7mgzfWpFQ/exec";
var infected_data = jQuery.ajax({
crossDomain: true,
url: url,
method: "GET",
//dataType: "jsonp"
});
如果我取消注释 jsonp,我会收到一个错误:
jquery-1.11.3.min.js:5 Cross-Origin Read Blocking (CORB) blocked cross-origin response https://script.googleusercontent.com/macros/echo?user_content_key=JXkCjiJjhcjndRREjoGyVNkZNkD-HvKpEPkpicQBm9nR9OkxjGXdYuOPsLxbJf-B9Rgifl5NWMtzgjfVGuMdGxTJrjKnRpdcOJmA1Yb3SEsKFZqtv3DaNYcMrmhZHmUMWojr9NvTBuBLhyHCd5hHazTNYZyoqG0ZuVXpWSNdoeLErB4AfUCNPKJHgELe5WaAmN5SlwIhonlWkkbFzR8kUwjKrMtdq9u-YqreD7W_KJ_aVqKVBTehAuogPCoZCfVc4yJf5ieDCdMDbXQ8FZZq8iSedsk1Px1LnPBLM8W-ZRcknnbJNT8dS525XG1pNEBR&lib= Mw_Scq3iKhByBS86NJpd_CngcdEShCw7K,MIME 类型为 application/json。有关详细信息,请参阅https://www.chromestatus.com/feature/5629709824032768 。
如果我删除它,我不会收到任何错误。但是,我仍然看不到交互式地图(我的应用程序)上的数据。
使用获取:
常量 url = "https://script.google.com/macros/s/AKfycbzsyQNJwDvQc5SvNGEDZZOoNI3XxNar9PA9sRucZx7mgzfWpFQ/exec";
// Declare an async function
const getData = async () => {
// Use the await keyword to let JS know this variable has some latency so it should wait for it to be filled
// When the variable is fetched, use the .then() callback to carry on
const DataJSON = await fetch(url).then(response =>
response.json()
).then(parsedResponse => parsedResponse)
return await DataJSON
};
console.log(getData());
var infected_data = getData();
将对象中的整数转换为字符串 对象需要采用如下格式:
var infected_data = {
cn: "83",
th: "0",
mo: "0",
au: "0",
sg: "0",
tw: "0",
us: "0",
jp: "0",
my: "0",
kr: "0",
fx: "0",
vn: "0",
kh: "0",
ca: "0",
ci: "0",
np: "0",
lk: "0",
};
