read rhe JSON from POST URL

Hi all,

 

I need to create a REST service URL  in apex, through which a PHP application POST a JSON object to me and then I need to read the JSON from that. please give any help about this.

 

My sample code:

 

@RestResource(urlMapping='/myapp/')
global with sharing class myController{

@HttpPOST
/* This is method is responsible for reading the JSON data*/
global static String doPOST()
{

       ////////////////////// read JSON /////////////////////////////

}

 

please help me regarding this problem.

global static String doPOST() {
  RestRequest req = RestContext.request;
  MyWrapperClass mwc = (MyWrapperClass)JSON.deserialize(req.requestBody,MyWrapperClass.class);
   // mwc now has my data from PHP.
}

MyWrapperClass is just some generic class that contains the fields you are receiving from the PHP script. You could also use the JSONParser object as well, or deserialize into a map, etc. You should probably read the documentation for JSON parsing so you have a better idea of how you'd like to structure your code.

Hi Vishal, If you are able to get URL through REST API you should use Json Parser Method to read data.

I applied the code as you suggested. I am posting JSON object from PHP code and but i am not getting anything in "req.requestBody" It is empty.

Hi

You can pass url by EndPoint.

You will receive input through HTTPResponse. Try my running code.

HttpRequest req = new HttpRequest();
Http http = new Http();
HTTPResponse res;
try{
	req.setEndPoint(URL);
	req.setMethod('POST');
	res = http.send(req);
	String s = res.getBody();
	JSONParser parser = JSON.createParser(s);
	while (parser.nextToken() != null) {
		if(parser.getCurrentToken() == JSONToken.FIELD_NAME)
			System.debug(parser.getCurrentName());
		else{
			System.debug(parser.getText());
		}
	}
}
catch(Exception e)
{}
