way to Ignore ssl certificate using HttpsURLConnection


I use two approaches to try to consumes HTTPS URL:

The old deprecated and return response with the right values.

Here is the code it didn't need ignore ssl certificate it ignore it by itself or may use other technique:

public String newApiPost(String url,String p1,String p2,String p3){

    HttpClient httpClient = new DefaultHttpClient();
    // replace with your url
    HttpPost httpPost = new HttpPost(url);

    //Post Data
    List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>();
    nameValuePair.add(new BasicNameValuePair("cliend_id",p1));
    nameValuePair.add(new BasicNameValuePair("client_secret", p2));
    nameValuePair.add(new BasicNameValuePair("key",p3));

    //Encoding POST data
    try {
        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
    } catch (UnsupportedEncodingException e) {
        // log exception
        e.printStackTrace();
    }

    //making POST request.
    try {
        HttpResponse response = httpClient.execute(httpPost);
        HttpEntity httpEntity = response.getEntity();
        String   result = EntityUtils.toString(httpEntity,     
        HTTP.UTF_8);
        Log.d("response", result);

        // write response to log
        Log.d("zzuu", result.toString());
    } catch (ClientProtocolException e) {
        // Log exception
        e.printStackTrace();
    } catch (IOException e) {
        // Log exception
        e.printStackTrace();
        Log.d("dddfg", e.toString());
    }catch (Exception e){
        Log.d("dddfg", e.toString());
    }

    return "";
 }

Then I used un-deprecated method HttpsUrlConnections which need ignore ssl certificate I use many way but didn't work:

public void sendNew (String urls,String paramValue1,String paramValue2,String paramValue3){
    URL url = null;
    BufferedReader reader = null;
    StringBuilder stringBuilder;
    String data="";

    try {
        url = new URL(urls);
        HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();

        conn.setReadTimeout(10000);
        conn.setConnectTimeout(15000);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        conn.setRequestProperty("charset", "utf-8");
        conn.setDoInput(true);
        conn.setDoOutput(true);
        Uri.Builder builder = new Uri.Builder()
                .appendQueryParameter("cliend_id", paramValue1)
                .appendQueryParameter("client_secret", paramValue2)
                .appendQueryParameter("apikey", paramValue3);
        String query = builder.build().getEncodedQuery();

        OutputStream os = conn.getOutputStream();
        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
        writer.write(query);
        writer.flush();
        writer.close();
        os.close();

        conn.connect();

        reader = new BufferedReader(new InputStreamReader(conn.getErrorStream()));
        stringBuilder = new StringBuilder();

        String line = null;
        while ((line = reader.readLine()) != null) {
            stringBuilder.append(line + "\n");
        }
        data= stringBuilder.toString();
        Log.d("zzuu", data);

    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (ProtocolException e) {
        e.printStackTrace();
        Log.d("dddfg", e.toString());

    } catch (IOException e) {
        e.printStackTrace();
        Log.d("dddfg", e.toString());

    }catch (Exception e){
        Log.d("dddfg", e.toString());

    }
}

It responds with this error:

I didn't understand when problem exactly it work good in restclient and postman the data send in body of url using post method then I discover that I need ignore ssl certificate when using HttpsURLConnection but I try many way to ignore but didn't work

I use

private void trustEveryone() {
    try {
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier(){
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        });
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, new X509TrustManager[]{new X509TrustManager(){
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {}
            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {}
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }
        }}, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(
        context.getSocketFactory());
    } catch (Exception e) { // should never happen
        e.printStackTrace();
    }
}

Solution

  • From your logcat information, I think you should read the following links:

    1. HostnameVerifier

      It is to be used during a handshake if the URL's hostname does not match the peer's identification hostname.

    2. Common Problems with Hostname Verification

      One reason this can happen is due to a server configuration error. The server is configured with a certificate that does not have a subject or subject alternative name fields that match the server you are trying to reach...

    Then, you can refer to my answer to the following question:

    OkHttp trusting certificate


    EDIT: Relating to your idea 'ignore ssl', you can try the following (however, it's said that this is not recommended):

    public class HttpsTrustManager implements X509TrustManager {
        private static TrustManager[] trustManagers;
        private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[]{};
    
        @Override
        public void checkClientTrusted(
                X509Certificate[] x509Certificates, String s)
                throws java.security.cert.CertificateException {
    
        }
    
        @Override
        public void checkServerTrusted(
                X509Certificate[] x509Certificates, String s)
                throws java.security.cert.CertificateException {
    
        }
    
        public boolean isClientTrusted(X509Certificate[] chain) {
            return true;
        }
    
        public boolean isServerTrusted(X509Certificate[] chain) {
            return true;
        }
    
        @Override
        public X509Certificate[] getAcceptedIssuers() {
            return _AcceptedIssuers;
        }
    
        public static void allowAllSSL() {
            HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
    
                @Override
                public boolean verify(String arg0, SSLSession arg1) {
                    return true;
                }
    
            });
    
            SSLContext context = null;
            if (trustManagers == null) {
                trustManagers = new TrustManager[]{new HttpsTrustManager()};
            }
    
            try {
                context = SSLContext.getInstance("TLS");
                context.init(null, trustManagers, new SecureRandom());
            } catch (NoSuchAlgorithmException | KeyManagementException e) {
                e.printStackTrace();
            }
    
            HttpsURLConnection.setDefaultSSLSocketFactory(context != null ? context.getSocketFactory() : null);
        }
    }
    

    Then, in your activity, call HttpsTrustManager.allowAllSSL();
