setting content type in rest assured

Question

I'm trying to invoke a rest call using rest assured. My API accepts, "application/json" as content type and I need to set in the call. I set the content type as mentioned below.

Option 1

Response resp1 = given().log().all().header("Content-Type","application/json")
   .body(inputPayLoad).when().post(addUserUrl);
System.out.println("Status code - " +resp1.getStatusCode());

Option 2

Response resp1 = given().log().all().contentType("application/json")
   .body(inputPayLoad).when().post(addUserUrl);

The response I get is "415" (indicates that "Unsupported media type ").

I tried invoking the same api using plain java code and it works. For some mysterious reason, I cudn't get it working through RA.

    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(addUserUrl);
    StringEntity input = new StringEntity(inputPayLoad);
    input.setContentType("application/json");
    post.setEntity(input);
    HttpResponse response = client.execute(post);
    System.out.println(response.getEntity().getContent());
    /*
    BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
    String line = "";
    while ((line = rd.readLine()) != null) {
        System.out.println("Output -- " +line);
    }

Answer 1

For your First option can you please try adding this header too and sending the request?

.header("Accept","application/json")

Answer 2

As mentioned in previous posts there is a method:

RequestSpecification.contentType(String value)

I did not work for me too. But after upgrade to the newest version (in this moment 2.9.0) it works. So please upgrade :)

Answer 3

Give a try given().contentType(ContentType.JSON).body(inputPayLoad.toString)

Answer 4

I was facing something similar and after some time we noticed the problem was actually coming from the server side. Please check your call on Postman and see if when it's triggered you need to change it from HTML to JSON. If you need to do that, the backend may need to force the response to be in JSON format by adding its content type. Even if it's encoded in JSON you're still may need to do that.

Thats the line of code we added:

header('Content-type:application/json;charset=utf-8');

.

  public function renderError($err){
   header('Content-type:application/json;charset=utf-8');
   echo json_encode(array(
       'success' => false,
       'err' => $err
   ));
}

And that's what was happening on the backend:

Hope that can help somehow. :)

Here is the Complete POST exmaple using CONTENT_TYPE as JSON.Hope it will help you.

RequestSpecification request=new RequestSpecBuilder().build();
ResponseSpecification response=new ResponseSpecBuilder().build();
@Test
public void test(){
   User user=new User();
   given()
    .spec(request)
    .contentType(ContentType.JSON)
    .body(user)
    .post(API_ENDPOINT)
    .then()
    .statusCode(200).log().all();
}
