I am creating connectors for REST API methods. Some methods has the same method name but performs different HTTP methods.
For example, createEntity( HttpMethod httpMethod, CreateEntity model ) can perform POST and GET only. What I want is to have an error when httpMethod is supplied with PUT or DELETE. The allowed httpMethod will depend every method. How can I do this validation inside CreateEntity.groovy?
Here is the HttpMethod.groovy
public enum HttpMethod {
POST,
DELETE,
GET,
PUT,
HEAD,
TRACE,
CONNECT,
PATCH
}
CreateEntity.groovy
private String field1;
private String field2;
//write here that only POST and GET are allowed
Connector.groovy
def createEntityQuery ( HttpMethod httpMethod, CreateEntityQuery model ) {
//perform operations
}
this must be valid:
createEntity( HttpMethod.POST, new EntityQuery([ field1 : "field1", field2 : "field2" ]))
createEntity( HttpMethod.GET, new EntityQuery([ field1 : "field1", field2 : "field2" ]))
this should throw an error:
createEntity( HttpMethod.PUT, new EntityQuery([ field1 : "field1", field2 : "field2" ]))
createEntity( HttpMethod.DELETE, new EntityQuery([ field1 : "field1", field2 : "field2" ]))
Is that what you're looking for:
public enum HttpMethod {
POST,
DELETE,
GET,
PUT,
HEAD,
TRACE,
CONNECT,
PATCH
}
class EntityQuery {
String field1
String field2
}
def createEntity(HttpMethod h, EntityQuery q) {
if(!(h in [HttpMethod.POST, HttpMethod.GET])) {
throw new Exception('Only POST and GET methods allowed')
}
}
createEntity(HttpMethod.PUT, new EntityQuery())
?
However it'd be better to expose public methods like createPostEntity or createGetEntity which will be accepting only EntityQuery as an argument and HttpMethod will be handled internally.
