How to get HttpClient returning status code and response body

Question

I am trying to get Apache HttpClient to fire an HTTP request  and then display the HTTP response code  200  404  500  etc   as well as the HTTP response body  text string   It is important to note that I am using v4 2 2 because most HttpClient examples out there are from v 3 x x and the API changed greatly from version 3 to version 4     Unfortunately I ve only been able to get HttpClient returning the status code or the response body  but not both      Here s what I have        Getting the status code   HttpClient client   new DefaultHttpClient     HttpGet httpGet   new HttpGet  http   whatever blah com     HttpResponse resp   client execute httpGet      int statusCode   resp getStatusLine   getStatusCode            Getting the response body   HttpClient client   new DefaultHttpClient     HttpGet httpGet   new HttpGet  http   whatever blah com     ResponseHandler lt String gt  handler   new BasicResponseHandler       String body   client execute httpGet  handler        So I ask  Using the v4 2 2 library  how can I obtain both status code and response body from the same client execute      call  Thanks in advance

You can avoid the BasicResponseHandler  but use the HttpResponse itself to get both status and response as a String   HttpResponse response   httpClient execute get       Getting the status code  int statusCode   response getStatusLine   getStatusCode        Getting the response body  String responseBody   EntityUtils toString response getEntity

Don t provide the handler to execute   Get the HttpResponse object  use the handler to get the body and get the status code from it directly  try  CloseableHttpClient httpClient   HttpClients createDefault          final HttpGet httpGet   new HttpGet GET URL        try  CloseableHttpResponse response   httpClient execute httpGet             StatusLine statusLine   response getStatusLine            System out println statusLine getStatusCode           statusLine getReasonPhrase             String responseBody   EntityUtils toString response getEntity    StandardCharsets UTF 8           System out println  Response body      responseBody             For quick single calls  the fluent API is useful   Response response   Request Get uri           connectTimeout MILLIS ONE SECOND           socketTimeout MILLIS ONE SECOND           execute    HttpResponse httpResponse   response returnResponse    StatusLine statusLine   httpResponse getStatusLine      For older versions of java or httpcomponents  the code might look different

BasicResponseHandler throws if the status is not 2xx  See its javadoc   Here is how I would do it   HttpResponse response   client execute  get    int code   response getStatusLine   getStatusCode    InputStream body   response getEntity   getContent       Read the body stream   Or you can also write a ResponseHandler starting from BasicResponseHandler source that don t throw when the status is not 2xx
