Get items from a SharePoint List using REST API

Question

I need to retrieve items from a SP List based on the Date_of_Event.

I want all items in the list which occurred the last month.

How does my request looks like?

var urlForOrderBy = "/_api/Web/Lists/GetByTitle('OIE Alerts')/Items?" +
    "$select=ID,Title,Country,Date_of_Event,LandCode," + .......
    &$orderby=Date_of_Event desc";

Answer 1

Something like:

var today = new Date();
var lastmonth = today.setMonth(today.getMonth()-1);

var urlForOrderBy = "/_api/Web/Lists/GetByTitle('OIE Alerts')/Items?" +
 "$select=ID,Title,Country,Date_of_Event,LandCode," + 
 "$filter=Date_of_Event gt " + lastmonth.toISOString() + 
 "&$orderby=Date_of_Event desc";

Answer 2

I solved the question.

var urlForAllItems = "/_api/Web/Lists/GetByTitle('OIE Alerts')/Items?" +
"$select=Title,Date_x0020_of_x0020_Event,Country0/Title,Country0/Column2&$expand=Country0&" +
 "$filter=Date_x0020_of_x0020_Event gt '"+startDate+"'&$orderby=Date_x0020_of_x0020_Event desc";
