I'm trying to Post RestAPI with form-data content in Groovy.

MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
multipartEntity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
multipartEntity.addPart("nationality", new StringBody("0082410999"));

HttpClient httpClient = HttpClientBuilder.create().build();
HttpPost postRequest = new HttpPost();

//////An error occurs on this line
postRequest.setEntity(multipartEntity.build())

Please help about this Error :

Caused by: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'org.apache.http.entity.mime.MultipartFormEntity@ee2abaf' with class 'org.apache.http.entity.mime.MultipartFormEntity' to class 'org.apache.http.HttpEntity'

Thanks a lot, Ali

See earlier answer at https://stackoverflow.com/a/54129889/5449431. That answer uses HttpBuilder which is a separate groovy library wrapping the apache client classes. – Matias Bjarland Apr 28 '19 at 13:13
