Send an HTTPS request to the server

Question

This is my HTTP JSON

{ "User": { "Name": "Compulsary","Password": "Compulsary" } } 

What I need to send to the server using the POST HTTPS request. When I try to send a request, I get an SSL Server Exception certificate. How can I fix this problem?

What have i tried?

I tried using HTTPPost with HTTPClient . SSL exception. I also tried using URLConnection and ignored the verification of SSL certificates. I get response codes 401 and 405.

Problem Statement:

Send the above POST request to the server (the request is secure accepts https). How to achieve this in android?

I tried this, my code, am I getting 405 error?

 // always verify the host - dont check for certificate final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() { public boolean verify(String hostname, SSLSession session) { return true; } }; /** * Trust every server - dont check for any certificate */ private static void trustAllHosts() { // Create a trust manager that does not validate certificate chains TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() { public java.security.cert.X509Certificate[] getAcceptedIssuers() { return new java.security.cert.X509Certificate[] {}; } public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException { } public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException { } } }; // Install the all-trusting trust manager try { SSLContext sc = SSLContext.getInstance("TLS"); sc.init(null, trustAllCerts, new java.security.SecureRandom()); HttpsURLConnection .setDefaultSSLSocketFactory(sc.getSocketFactory()); } catch (Exception e) { e.printStackTrace(); } } private void makeRequest() { URL url = null; HttpsURLConnection urlConnection = null; try { url = new URL("https://wbapi.cloudapp.net:443/api/User/LocalLogin"); } catch (MalformedURLException e2) { // TODO Auto-generated catch block e2.printStackTrace(); } StringBuilder sb = new StringBuilder(); try { trustAllHosts(); urlConnection = (HttpsURLConnection) url.openConnection(); urlConnection.setHostnameVerifier(DO_NOT_VERIFY); urlConnection.setDoOutput(true); urlConnection .setRequestProperty("Content-Type", "application/json"); urlConnection.setFixedLengthStreamingMode(urlConnection .getContentLength()); } catch (IOException e2) { // TODO Auto-generated catch block e2.printStackTrace(); } try { urlConnection.connect(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } JSONObject jsonParam = new JSONObject(); try { jsonParam.put("Name", "dog"); jsonParam.put("Password", "123"); Log.v("Length", "" + urlConnection.getContentLength()); int HttpResult = urlConnection.getResponseCode(); Toast.makeText(LoginActivity.this, "Response" + HttpResult, Toast.LENGTH_LONG).show(); if (HttpResult == HttpsURLConnection.HTTP_OK) { System.out.println("ok"); Log.v("Hi", "" + "Trex"); BufferedReader br = new BufferedReader(new InputStreamReader( urlConnection.getInputStream(), "utf-8")); String line = null; while ((line = br.readLine()) != null) { sb.append(line + "\n"); } br.close(); System.out.println("" + sb.toString()); Toast.makeText(LoginActivity.this, "" + sb.toString(), Toast.LENGTH_LONG).show(); } else { System.out.println("Here" + urlConnection.getResponseMessage()); } } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } }

Step 1: Create the MySSLSocketFactory class and include the code below:

 public class MySSLSocketFactory extends SSLSocketFactory { SSLContext sslContext = SSLContext.getInstance("TLS"); public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException { super(truststore); TrustManager tm = new X509TrustManager() { public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException { } public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException { } public X509Certificate[] getAcceptedIssuers() { return null; } }; sslContext.init(null, new TrustManager[] { tm }, null); } @Override public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException { return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose); } @Override public Socket createSocket() throws IOException { return sslContext.getSocketFactory().createSocket(); } } 

Step 2: Create the WebClientDevWrapper class and include the code below:

 public class WebClientDevWrapper { public static HttpClient getNewHttpClient() { try { KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType()); trustStore.load(null, null); SSLSocketFactory sf = new MySSLSocketFactory(trustStore); sf.setHostnameVerifier( SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER); HttpParams params = new BasicHttpParams(); HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); HttpProtocolParams.setContentCharset(params, HTTP.UTF_8); SchemeRegistry registry = new SchemeRegistry(); registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80)); registry.register(new Scheme("https", sf, 443)); ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry); return new DefaultHttpClient(ccm, params); } catch (Exception e) { return new DefaultHttpClient(); } } } 

Step 3: Create a method inside your activity or elsewhere, this method will be used to create a web call.

 /** * Request JSON based web service to get response * * @param url * - base URL * @param request * - JSON request * @return response * @throws ClientProtocolException * @throws IOException * @throws IllegalStateException * @throws JSONException */ public HttpResponse request(String url, JSONObject request) throws ClientProtocolException, IOException, IllegalStateException, JSONException { DefaultHttpClient client = (DefaultHttpClient) WebClientDevWrapper.getNewHttpClient(); HttpPost post = new HttpPost(url); post.setEntity(new StringEntity(request.toString(), "utf-8")); HttpResponse response = client.execute(post); return response; } } 

Step 4: Call the method and get the answer.

Answer 2

I use the following codes for a combination of https / http / wift / 3G, hope this helps

 public class CustomHttpClient { private static DefaultHttpClient customHttpClient; /** A private Constructor prevents instantiation */ private CustomHttpClient() { } public static synchronized DefaultHttpClient getHttpClient() { if (customHttpClient == null) { HttpParams params = new BasicHttpParams(); HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); HttpProtocolParams.setContentCharset(params, HTTP.DEFAULT_CONTENT_CHARSET); HttpProtocolParams.setUseExpectContinue(params, true); HttpProtocolParams.setUserAgent(params, "Mozilla/5.0 (Linux; U; Android 2.2.1; en-us; Nexus One Build/FRG83) AppleWebKit/533.1(KHTML, like Gecko) Version/4.0 Mobile Safari/533.1"); ConnManagerParams.setTimeout(params, 1000); HttpConnectionParams.setConnectionTimeout(params, 5000); HttpConnectionParams.setSoTimeout(params, 10000); SchemeRegistry schReg = new SchemeRegistry(); schReg.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80)); schReg.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443)); ClientConnectionManager conMgr = new ThreadSafeClientConnManager(params,schReg); customHttpClient = new DefaultHttpClient(conMgr, params); } return customHttpClient; } public Object clone() throws CloneNotSupportedException { throw new CloneNotSupportedException(); } 

}

and sample

 public static String Call(String URL, List<NameValuePair> postParameters) { BufferedReader in = null; DefaultHttpClient httpClient; StringBuffer sb = new StringBuffer(); try{ httpClient = CustomHttpClient.getHttpClient(); HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), false); //making 3G network works* HttpPost request = new HttpPost(URL); UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(postParameters); request.setEntity(formEntity); HttpResponse response = httpClient.execute(request); in = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); String line = ""; String NL = System.getProperty("line.separator"); while ((line = in.readLine()) != null) { sb.append(line + NL); } in.close(); }catch(Exception ex) { ex.printStackTrace(); } return sb.toString(); }
