How to connect Blogger website with Google spreadsheet using Google App script? - google-sheets

Question

I want to know if I can use Google spreadsheet as a back-end database for my Blogger website. I have done so in past using Google Fusion Tables.
I can use Web Apps as well by using a custom domain to direct to their long URL. But when I update the script, I have to deploy the web app. This changes the long URL, so I need to update my redirection.
Is there a way to access & update a Google Spreadsheet from my website.

Answer 1

You cannot do this with Blogger.
However, you can do this with Sites.
If you setup a spreadsheet like this:
Then you create a web app from that like this:
var sheet = SpreadsheetApp.openByUrl("YOUR URL").getSheetByName("LinkConfig");
function getDataIndex(key) {
var Keys = sheet.getRange(2, 1, sheet.getMaxColumns(), 1).getValues().map(function(row) {return row[0]});
for (var i=0; i<Keys.length; i++) {
if (Keys[i]==key) return i+2;
}
}
function getData(key) {
return sheet.getRange(getDataIndex(key), 2).getValue();
}
function test() {
Logger.log(getData("url1"));
Logger.log(getData("url2"));
}
function webApp(key) {
//Get contents from target URL
var content = UrlFetchApp.fetch(getData(key)).getContentText();
return HtmlService.createHtmlOutput(content); //Returns new page with the same content
}
function doGet(e) {
if (e.parameter.key != null && e.parameter.key != undefined) {
return webApp(e.parameter.key);
} else {
return HtmlService.createHtmlOutput("<h1>Error! You didn't specify a 'key' parameter</h1>");
}
}
And deploy it.
Now, as long as you don't change that one URL (meaning you don't edit this main "config" webapp, you are able to change values on the spreadsheet and access the pages linked there by passing the key.
To use it in Sites, add an Embed element and set the URL to : yourwebappurl?key=keyvalue
