Set parameters with HTTP POST in Apex - salesforce

Question

I'm trying to set POST content using Apex. The example below sets the variables using GET
PageReference newPage = Page.SOMEPAGE;
SOMEPAGE.getParameters().put('id', someID);
SOMEPAGE.getParameters().put('text', content);
Is there any way for me to set the HTTP type as POST?

Answer 1

Yes but you need to use HttpRequest class.
String endpoint = 'http://www.example.com/service';
String body = 'fname=firstname&lname=lastname&age=34';
HttpRequest req = new HttpRequest();
req.setEndpoint(endpoint);
req.setMethod('POST');
req.setbody(body);
Http http = new Http();
HTTPResponse response = http.send(req);
For additional information refer to Salesforce documentation.

The following apex class example will allow you to set parameters in the query string for a post request -
#RestResource(urlmapping = '/sendComment/*')
global without sharing class postComment {
#HttpPost
global static void postComment(){
//create parameters
string commentTitle = RestContext.request.params.get('commentTitle');
string textBody = RestContext.request.params.get('textBody');
//equate the parameters with the respective fields of the new record
Comment__c thisComment = new Comment__c(
Title__c = commentTitle,
TextBody__c = textBody,
);
insert thisComment;
RestContext.response.responseBody = blob.valueOf('[{"Comment Id":
'+JSON.serialize(thisComment.Id)+', "Message" : "Comment submitted
successfully"}]');
}
}
The URL for the above API class will look like -
/services/apexrest/sendComment?commentTitle=Sample title&textBody=This is a comment
