  • Open the Script Manager

    cron3

  • Click On NEW to create a new script

    cron4

  • Rename the script to "CronJob"

function cronExecute() {

var url = "http://www.YOURWEBSITE.com/FULL_URL";

var options = {
"method" : "get",
"headers" : {'User-Agent' : 'Mozilla Firefox 8.0',
             'Accept-Charset' : 'ISO-8859-1,utf-8;q=0.7,*;q=0.7'
            },
"payload" : "",
"contentType" : "application/xml; charset=utf-8"
};

var request_starttime = new Date();
// fetch the HTTP / HTTPS request and get the response
var response = UrlFetchApp.fetch(url,options);
var request_endtime = new Date();

// use any spreadsheet, use its key
// var ss = SpreadsheetApp.openById("YOUR-SHEET-KEY");
// use this script's default spreadsheet
var ss = SpreadsheetApp.getActiveSpreadsheet();
// get the worksheet
var sheet = ss.getSheets()[0];

// inserting values into the sheet
sheet.insertRowBefore(1);
var colValues = [[ request_starttime, request_endtime,
                 response.getResponseCode(), response.getHeaders().toSource(),
                 url, response.getContentText() ]];
sheet.getRange(1, 1, 1, 6).setValues(colValues);

// if something is not working, use the Logger object/function (uncomment it and modify it)
// Logger.log(ss.getSpreadsheetTimeZone());

// view the log details from VIEW -> LOGS

// You can also RUN the script and view its Execution log
// try this VIEW -> EXECUTION TRANSCRIPTS

// Make sure you MODIFY and then RUN the script and
// verify its working OK by looking at the spreadsheet contents
// try this RUN -> CRONEXECUTE
// check the spreadsheet contents

// After its working OK, you should setup a TRIGGER to execute it as and when you want (frequency)
// try this TRIGGERS -> ALL YOUR TRIGGERS

}
  • Modify the above script for your own URL, SPREADSHEET-KEY, HTTP-REQUEST-METHOD, HTTP-PAYLOAD, HTTP-CONTENT-TYPE, HTTP_HEADERS, LOG-OUTPUT-VALUES

  • Lets start with an example - I have setup the trigger to run my CRON job every minute

    cron24

  • Modify and Use the following code to customize it to your needs

    
function cronExecute() {

var url = "http://www.YOURWEBSITE.com/FULL_URL";

// use whatever options as described previously
var options = {"method" : "get"};

// fetch current time
var now = new Date();

// we will execute the URL Fetch Job only if it satisfies our requirements

// you can store the custom config data params in a datastore and use them here
// for eg - get config data via JDBC using the JDBC Service listed above
// or use Google Docs as data store and get config data from there

// use javascript date / time functionality to try out different combinations

// Javascript time reference - http://www.w3schools.com/jsref/jsref_obj_date.asp

now_offset= now.getTimezoneOffset();
now_day_of_month= now.getDate(); // (1-31)
now_day_of_week= now.getDay(); // (0-6)
now_year= now.getFullYear(); // (xxxx)
now_month= now.getMonth(); // (0-11)
now_hour= now.getHours(); // (0-23)
now_minute= now.getMinutes(); // (0-59)
now_second= now.getSeconds(); // (0-59)
now_millisecond= now.getMilliseconds(); // (0-999)

// NOTE - Here we have setup a per-minute trigger job so we can capture upto the minute
// NOTE - Always setup the correct TRIGGER as per your required frequency - minute/hour/day/week
// NOTE - Then add any custom config checks over here
// NOTE - Make sure you TEST RUN your custom script and see if its working as expected
// NOTE - Use Logger.Log(msg) to log your data and view it in VIEW -> LOGS menu in your SCRIPT EDITOR

// run every hour at xx:15
if( now_minute == 15 )
{
	var response = UrlFetchApp.fetch(url,options);
	// and do all the stuff, as described previously
}

// Use your imagination to do anything with the configuration

// run every 1st day of the year (month range is 0-11)
if( now_day_of_month ==1 && now_month = 0 )

// run every Last day of the year
if( now_day_of_month ==31 && now_month = 11 )

// run every 10th of the month
if( now_day_of_month ==10 )

// run every 30 minutes, at xx:00 and xx:30
if( now_minute == 0 ||  now_minute == 30 )

// run every 20 minutes, at xx:05 xx:25 xx:45 (OR condition used)
if( now_minute == 05 ||  now_minute == 25 ||  now_minute == 45 )

// run every hour at xx:20
if( now_minute == 20 )

// run every 2 hours at odd:20
if( now_hour%2==1 && now_minute == 20 )

// run every 2 hours at even:10
if( now_hour%2==0 && now_minute == 10 )

// run every day at 11:15 AM
if( now_hour == 11 && now_minute == 15 )

// run every week on Monday at 12:00 PM noon
if( now_day_of_week == 1 && now_hour == 12 && now_minute ==0 )
