Unable to read 404 error response body from azure

I am trying to read the response body for an error response(404,400,500) using java application and basic http client. When testing in my local , I am able to get the proper json response. But when I deployed to azure I am getting the error response body in HTML tags.
Error response I got when deployed to azure and testing from there:
400 Error400 error while attempting to access resource

Kindly looking for some one who can shed throw light.. Thanks you so much..

Check to make sure that your API key is correct. Many people who have this problem are using zeros ('0') instead of the letter 'O', and vice-versa. '1' and 'l' can be a problem as well.

I tried from POSTMAN API working fine but not from my Java code?

Please I have gone through all the question from stackoverflow, but those are not applicable to my problem.
Please have look in image request working fine from POSTMAN.
But When I tried from android code it is not working.
My Sample Android code is here.
#Override
protected String doInBackground(Void... params) {
HttpURLConnection urlConnection = null;
BufferedReader reader = null;
// Will contain the raw JSON response as a string.
String forecastJsonStr = null;
try {
URL url = new URL("sample url");
String postData = "key1=valu1&key2=valu2";
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(55000 /* milliseconds */);
conn.setConnectTimeout(55000 /* milliseconds */);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os));
writer.write(postData);
writer.flush();
writer.close();
os.close();
int responseCode=conn.getResponseCode();
if (responseCode == HttpsURLConnection.HTTP_OK) {
BufferedReader in=new BufferedReader(
new InputStreamReader(
conn.getInputStream()));
StringBuffer sb = new StringBuffer("");
String line="";
while((line = in.readLine()) != null) {
Log.e("response ",line);
sb.append(line);
break;
}
in.close();
return sb.toString();
}
else {
return new String("false : "+responseCode);
}
} catch (Exception e) {
Log.e("PlaceholderFragment", "Error ", e);
// If the code didn't successfully get the weather data, there's no point in attemping
// to parse it.
return null;
} finally {
if (urlConnection != null) {
urlConnection.disconnect();
}
if (reader != null) {
try {
reader.close();
} catch (final IOException e) {
}
}
}
}
Above java code return 405 error code. I also tried from OkHttp also.
Please help.

Putting a '/' at the end of URL causes the redirect to happen because your server likes urls that end in '/'. POST is fully supported by the URL your server redirects you to, but the client is executing a GET request when it behaves according to your setRedirecting() call (cURL does the same exact thing with the -L switch) The fix is to either put a '/' at the end of URL, or to grab the Location header from the response yourself and then initiate another POST request manually.
This can be observed in wireshark. You can test the theory by trying to perform a GET request with your browser to the URL with a slash appended to it. That will cause the browser to get a 405. Here's the fixed code for Android, this code uses the simple fix of appending a '/' to the URL (not production ready):
Read more from here.
Do let me know if this helps :)
Additionally, try using this piece of code:
public void postData() {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://your URL");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("id", "12345"));
nameValuePairs.add(new BasicNameValuePair("stringdata", "Hi"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}

Your API call is reciveving data in GET parameter. So data should send along with url as given below
String postData = Uri.encode("key1=valu1&key2=valu2");
URL url = new URL("sample url"+"?+postData);

I just had a similar problem with the HttpClient in Java. The solution was to specify the HTTP version explicitly:
HttpClient.newBuilder()
.version(HttpClient.Version.HTTP_1_1)
.build();
Now my requests returns the same result as through Postman.

how to call web service in java using post method

public static String[] Webcall(String emailID) {
try {

return null;
}
This is my code I am trying to call web service and get data.
But when I hit web service then I am getting below exception
Failed : HTTP error code : 404
Please suggest me where am doing wrong try to give solution for this .

The first thing is check url is it working on computer using postman or restclient and if it is working fine then tried to post using below code, this code is for posting data in json format using HttpPost you can use retrofit lib as Milad suggested.
public static String POST(String url, String email)
{
InputStream inputStream = null;
String result = "";
try {
// 1. create HttpClient
HttpClient httpclient = new DefaultHttpClient();
// 2. make POST request to the given URL
HttpPost httpPost = new HttpPost(url);
String json = "";
// 3. build jsonObject
JSONObject jsonObject = new JSONObject();
jsonObject.accumulate("email", email);
// 4. convert JSONObject to JSON to String
json = jsonObject.toString();
// 5. set json to StringEntity
StringEntity se = new StringEntity(json);
// 6. set httpPost Entity
httpPost.setEntity(se);
// 7. Set some headers to inform server about the type of the content
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
// 8. Execute POST request to the given URL
HttpResponse httpResponse = httpclient.execute(httpPost);
// 9. receive response as inputStream
inputStream = httpResponse.getEntity().getContent();
// 10. convert inputstream to string
if(inputStream != null)
result = convertInputStreamToString(inputStream);
else
result = "Did not work!";
} catch (Exception e) {
Log.d("InputStream", e.getLocalizedMessage());
}
// 11. return result
return result;
}
private static String convertInputStreamToString(InputStream inputStream) throws IOException{
BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream));
String line = "";
String result = "";
while((line = bufferedReader.readLine()) != null)
result += line;
inputStream.close();
return result;
}

I think u should try to re-check URL that you send request to.
follow the output error, code 404 that mean the URL is broken or dead link.

You can do the same by using jersy-client and jersy core.Here is the code snippet
private static void generateXML(String xmlName, String requestXML, String url)
{
try
{
Client client = Client.create();
WebResource webResource = client
.resource(url);
ClientResponse response = (ClientResponse)webResource.accept(new String[] { "application/xml" }).post(ClientResponse.class, requestXML);
if (response.getStatus() != 200) {
throw new RuntimeException("Failed : HTTP error code : " + response.getStatus());
}
String output = (String)response.getEntity(String.class);
PrintWriter writer = new PrintWriter(xmlName, "UTF-8");
writer.println(output);
writer.close();
}
catch (Exception e) {
try {
throw new CustomException("Rest-Client May Be Not Working From Your System");
} catch (CustomException e1) {
System.exit(1);
}
}
}
Call this method from your code with varibales.

RESTClient using HTTP Get Request

I am trying to write a JSON Client which uses HTTP GET method,and I am getting an response of 500.The code I have tried is below,Is there any wrong with the same?The request parameter I am trying to set is entityName=Nila and parentEntity=500000001 as parameters.
URL url = new URL("http://192.168.210.74:9763/services/testEntityService?entityName=Nila&parentEntity=500000001");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Accept", "application/json");
if (conn.getResponseCode() != 200) {
throw new RuntimeException("Failed : HTTP error code : "
+ conn.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader(
(conn.getInputStream())));
String output;
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
}
conn.disconnect();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

Its an internal server error yes the problem is on server side.
