Regarding Rest Services using Rest Api

Question

@RestResource(urlMapping='/Account13/*')

global with sharing class  MyRestResource13 {
@HttpPost
 global static string sendAccount(){

        RestRequest req  = RestContext.request;
        RestResponse res = RestContext.response;
        system.debug(req);
        system.debug(res);
       // map<account,object> account1  = new map<account,object>();

        Blob body = req.requestBody;
        system.debug(body);
        string body1 =body.toString();
        system.debug(body1);


        dto df = (dto)json.deserialize(body1 ,dto.class);
        dto dl = new dto(df.name,df.phone,df.website);

        system.debug(df);

        Account a = new account();
        //a.name=df.name;
        insert a;
        system.debug(dl);
        return json.serialize(dl);

        }



public class dto
{
public string Name{get;set;}
public string phone{get;set;}
public string website{get;set;}
  public dto(String Name,String phone,String Website)
  {
    this.Name=Name;
    system.debug(Name);
    this.phone=phone;
    system.debug(phone);
    this.website=website;
    system.debug(website);
   }
}
}

If we Change the Annotations @Httpput and @Httpget also it is Working,then what is the difference between put,get and post,Please anyone Explain with above Code

Answer 1

The difference between PUT, GET, and POST is almost just convention. If you're writing a service which is querying a database and returning result(s), you'd tend to make it GET. If you're creating an object, you'd tend to use PUT. Since you're writing the service, you can choose the method that makes most sense. For your sendAccount() method, I'd use PUT. That said, I've used REST services which use GET for everything (that has the slight advantage of being what web browsers use, so you can test your service with just a browser).

Technically, there are differences in how the different verbs should behave and the gory details available in these two links:
