Get response body on 400 HTTP response in Android?

Question

I\'m communicating with an API that I can not change that sends a 400 response when a request is not validated on the API side. It is a valid HTTP request, but the request data

Answer 1

Try that way:

if (this.responseCode == HttpURLConnection.HTTP_OK) {
 inputStream = httpUrlConnection.getInputStream();
} else {
inputStream = httpUrlConnection.getErrorStream();
}

Answer 2

Something like this, using org.apache.http.util.EntityUtils:

HttpRequestBase base = new HttpGet(url);
HttpResponse response = httpClient.execute(base);
String jsonString = EntityUtils.toString(response.getEntity());

PS: This is blind coding as I don't know what you tried yet.

To get status code:

int statusCode = response.getStatusLine().getStatusCode();

To get the entity body in byte array:

byte[] data = EntityUtils.toByteArray(response.getEntity());

Answer 3

This is how I send and get Http response as an byte[].Of course you can change it to string if you want.

                byte[] buffer = new byte[1024];
                httpclient = new DefaultHttpClient();
                httppost = new HttpPost("http://www.rpc.booom.com");



                postParameters = new ArrayList<NameValuePair>();
                postParameters.add(new BasicNameValuePair("debug_data","1"));
                postParameters.add(new BasicNameValuePair("client_api_ver", "1.0.0.0"));
                postParameters.add(new BasicNameValuePair("device_identificator", deviceId));
                postParameters.add(new BasicNameValuePair("device_resolution", resolution));
                postParameters.add(new BasicNameValuePair("username_hash", hashUser(username,password)));
                postParameters.add(new BasicNameValuePair("password_hash", hashPass(username,password)));

                httppost.setEntity(new UrlEncodedFormEntity(postParameters));

                HttpResponse response = httpclient.execute(httppost);
                Log.w("Response ","Status line : "+ response.getStatusLine().toString());
                buffer = EntityUtils.toString(response.getEntity()).getBytes();

Hope it helps!
