Class HttpException

All Implemented Interfaces:

public class HttpException
extends RuntimeException
HTTP Exception with support for converting the error response body into a bean.

Wraps an underlying HttpResponse with helper methods to get the response body as string or as a bean.

Example catching HttpException

   try {
         .formParam("email", "")
         .formParam("url", "notAValidUrl")

     } catch (HttpException e) {

       // obtain the statusCode from the exception ...
       int statusCode = e.statusCode());

       HttpResponse<?> httpResponse = e.httpResponse();

       // obtain the statusCode from httpResponse ...
       int statusCode = httpResponse.statusCode();

       // convert error response body into a bean (typically Jackson/Gson)
       final MyErrorBean errorResponse = e.bean(MyErrorBean.class);

       final Map<String, String> errorMap = errorResponse.getErrors();
       assertThat(errorMap.get("url")).isEqualTo("must be a valid URL");
       assertThat(errorMap.get("name")).isEqualTo("must not be null");
