Answer 1

you can get body of Bad Request in HttpURLConnection using this code :

InputStream errorstream = connection.getErrorStream();

String response = "";

String line;

BufferedReader br = new BufferedReader(new InputStreamReader(errorstream));

    response += line;
}

Log.d("body of Bad Request HttpURLConnection", "Response: " + response);

Use Apache Httpclient:

        String url = "http://192.168.1.6:7003/life/lifews/getFirstInstallment.html?rootPolicyNo=1392/2126/2/106/9995/1904&token=1984";
        HttpClient client = HttpClientBuilder.create().build();
        HttpGet request = new HttpGet(url);

        // add request header
        HttpResponse response = client.execute(request);
        System.out.println("Response Code : " + response.getStatusLine().getStatusCode());
        BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuffer result = new StringBuffer();
        String line = "";
        while ((line = rd.readLine()) != null)
            result.append(line);
        System.out.println(result);
