2. Exmaple

Java code

// init client
Client client = ClientBuilder.newClient();
// Demo API
// Using google app script simple api for demo
String link = "https://script.google.com/macros/s/AKfycbyPthJ8iO6B1fPR1YBVvltBQz4dvAnrtE48sw0VxqMIW-XwejTsS4db3Pgw3oUWA4U/exec";
Response response = client
  .target(link)
  .request(MediaType.APPLICATION_JSON)
  .get();

// read response body
String body = response.readEntity(String.class);

System.out.println("response = " + response);
System.out.println("response.getStatus() = " + response.getStatus());
System.out.println("body = " + body);

// junit check
Assert.assertEquals(200, response.getStatus());

Run console

response = InboundJaxrsResponse{context=ClientResponse{method=GET, uri=https://script.google.com/macros/s/AKfycbyPthJ8iO6B1fPR1YBVvltBQz4dvAnrtE48sw0VxqMIW-XwejTsS4db3Pgw3oUWA4U/exec, status=200, reason=OK}}
response.getStatus() = 200
body = {"content":[{"status":"success"}]}
