**I am Accessing the Class using postMan I am Writing the Code like

@RestResource(urlMapping='/create Event2/')
global class JSON2Apex {
   @Httppost
   global  static void consumeObject(JSONParser parser) {

It is Showing Error like

Error: Compile Error: Invalid type for Http* method: System.JSONParser at line 6 column 24

How to Rectify the Error**

This is My Entire Code:

@RestResource(urlMapping='/create Event2/')

 global class JSON2Apex {
@Httppost

   global  static void consumeObject(JSONParser parser) {
    system.debug(parser);
        Integer depth = 0;
        do {
            JSONToken curr = parser.getCurrentToken();
            system.debug(curr);
            if (curr == JSONToken.START_OBJECT || 
                curr == JSONToken.START_ARRAY) {
                depth++;
            } else if (curr == JSONToken.END_OBJECT ||
                curr == JSONToken.END_ARRAY) {
                depth--;
            }
        } while (depth > 0 && parser.nextToken() != null);
    }


    public List<Eventitems> eventitems {get;set;} 

    public JSON2Apex(JSONParser parser) {

  • have you created any parser class ? – Ratan Paul Jul 5 '16 at 6:21

  • ahh looks like you are not clear how to use Json2Apex generated class. look the generated class you need to save in new class. then when you get the JSON in consumeObject method use that class (Json2Apex generated class) for deserialize. check this ceus-now.com/how-to-deserialize-a-json-string-to-apex – Ratan Paul Jul 5 '16 at 6:31

How to deserialize a JSON String to Apex

Use http://json2apex.herokuapp.com/ to generate you class

and save that class in your salesforce org

now in your rest service class

@RestResource(urlMapping='/create Event2/')
global class MyService {
    @HttpPost
    global static void consumeObject() {
        JSON2Apex objJSON = JSON2Apex.parse(RestContext.request.requestBody.toString());
    }
}

This will deserialize your JSON

  • Above Code we have to write in Seperate Rest Service Class ah? – user31717 Jul 5 '16 at 6:45
  • @Salesforce yes man – Ratan Paul Jul 5 '16 at 6:47
