Parse complex JSON response from REST call

I use the REST api of google to trigger a search on their search engine. This works as expected. The result of the call is a complex JSON string.

How can I comfortably access this complex result in ivy. With Java or ivyScript?

One Answer:

You can easily access the JSON response content if you:

use a java pojo generator that creates a complex java class structure out of a JSON string
use Gson to parse the JSON string into instances of the generated java classes.

Generate classes:

Copy the whole JSON string into your clipboard and paste it into a java generator: http://www.jsonschema2pojo.org/
Configure the generator:
package = com.google.generated
class = QueryResponse
source type = JSON
annotation style = GSON
generate the java source by pressing on the "JAR" button.
download the generated sources jar.
copy the content of the sources-jar into your ivy projects sources folder

Parse JSON as java objects

add the latest gson.jar to our classpath: download the jar -> switch to java perspective -> copy the jar into a directory of the project -> right click on jar -> build path -> add to build path
QueryResponse response = new Gson().fromJson("{yourComplexResponse}", QueryResponse.class);
