How to Use Both HTTPS and HTTP to parse JSON data

问题:

I followed this to Parse Json In Android

I have Successfully Done it with HttpData handler..

Here I am Successfully Posting Data to server and Getting Response..

Now I want to Use this same in the Part of HTTPS..

Can Any one suggest me How to do this Without Major Changes in my code.. Because In my application I am doing this for more activities.. Please Suggest me to Use HTTPs in my code..

I will provide Additional Info... Depending Responses...

Update In my code I have Changed HttpURLConnection to HttpsURLConnection

Please suggest me How to through this error In my code..

Update 1

I have Changed Certificate on server side.. Now its working On Https..

But Now,

I want to Use HTTP and HTTPS Both in one app Depending on Client Requirement So here now its worked with Https....

But I also need to work with Http In my Code Can any any one suggest me...I want I should Work with Https and Http Both In one App.

to use both HTTP and HTTPS, you need to have the 2 methods (i think you already have them)

1. GetHTTPData(String urlString)
2. GetHTTPSData(String urlString)

now in HTTPDataHandler class (where you have both methods above) you need to create a 3rd method GetDataFromUrl(), that will check URL and decide which method to use (http or https)

public String GetDataFromUrl(String url){
    if(url.toLowerCase().startsWith("https")){
        //HTTPS:
        return GetHTTPSData(url);
    }else{
        //HTTP:
        return GetHTTPData(url);
    }
}

now in the AsyncTask class ProcessJSON

replace this line stream = hh.GetHTTPData(urlString);

with this one stream = hh.GetDataFromUrl(urlString);

if you don't want to add that 3rd method in HTTPDataHandler, just use the if-statement in ProcessJSON at doInBackground() to call either one of the 2 methods (http or https)

You can use HttpsURLConnection, replace HttpURLConnection by HttpsURLConnection .

   public String GetHTTPData(String urlString){
        try{
            URL url = new URL(urlString);
            HttpsURLConnection urlConnection =(HttpsURLConnection)url.openConnection();

            // Check the connection status
            if(urlConnection.getResponseCode() == 200)
            {
                // if response code = 200 ok
                InputStream in = new BufferedInputStream(urlConnection.getInputStream());

                // Read the BufferedInputStream
                BufferedReader r = new BufferedReader(new InputStreamReader(in));
                StringBuilder sb = new StringBuilder();
                String line;
                while ((line = r.readLine()) != null) {
                    sb.append(line);
                }
                stream = sb.toString();
                // End reading...............

                // Disconnect the HttpURLConnection
                urlConnection.disconnect();
            }
            else
            {
                // Do something
            }
        }catch (MalformedURLException e){
            e.printStackTrace();
        }catch(IOException e){
            e.printStackTrace();
        }finally {

        }
        // Return the data from specified url
        return stream;
    }

What I understand is in your server side, they used self signed SSL certificate. So you have to install that certificate in your android device also. Settings > Security > install form storage.But for production build you have to buy ssl certificate from CA Authorities. Hope this will solve your problem.

Remove HttpDataHandler lines in doInBackground use HttpUrlConnection directly in doInBackground or use HttpUrlConnection in JSONparse class to post params to server follow this tutorial to post params Website

I have same issue so i have uses this code

// 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
  */
 @SuppressLint("TrulyRandom")
 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();
    }
 }

Updated code as per your requirement.

 public String postData(String urlString) throws JSONException, IOException
 {
     String result = "";
     try
        {

        HttpURLConnection http = null;
        URL url = new URL(urlString);

        if (url.getProtocol().toLowerCase().equals("https"))
        {
            trustAllHosts();
            HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
            https.setHostnameVerifier(DO_NOT_VERIFY);
            http = https;
        }
        else {
            http = (HttpURLConnection) url.openConnection();
        }
        Log.i("getDate", "="+http.getDate());
        http.connect();
        result = convertStreamToString((InputStream)http.getContent());
        Log.i("tag", "="+result);
        return result;
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}
static String convertStreamToString(java.io.InputStream is)
{
    java.util.Scanner s = new java.util.Scanner(is).useDelimiter("\\A");
    return s.hasNext() ? s.next() : "";
}

replace this line stream = hh.GetHTTPData(urlString);

with this one stream = postData(urlString);
