title: Rest Assured - can't POST with Parameters and Body
body: <p>I'm testing a REST api using Rest Assured. I'm running into an error when trying to POST with both a parameter in the url and body content. This works correctly when testing manually. Removing the parameter form the url is not an option</p>
  
  <p>Test Code:</p>
  
  <pre><code>String endpoint = http://localhost:8080/x/y/z/id?custom=test;
  String body = "[{\"boolField\":true,\"intField\":991},
                  {\"boolField\":false,\"intField\":998}]";
  expect().spec(OK).given().body(body).post(endpoint);
  </code></pre>
  
  <p>Which throws the following error when run</p>
  
  <pre><code>You can either send parameters OR body content in the POST, not both!
  
  java.lang.IllegalStateException: You can either send parameters OR body content in the POST, not both!

  <p>Why does Rest Assured not allow both parameters and body content in a POST? </p>
