I am trying to access a locally hosted website and get its HTML source to parse. I have few questions:
1) Can I use "https://An IP ADDRESS HERE" as a valid URL to try and access. I do not want to make changes in the /etc/hosts file so I want to do it this way.
2) I cannot get the html, since it is giving me Handshake exceptions and Certificate issues. I have tried a lot of help available over the web , but am not successful.
Here is the code I am using:
public class MainActivity extends Activity {
private TextView textView;
String response = "";
String finalresponse="";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.TextView01);
System.setProperty("javax.net.ssl.trustStore","C:\\User\\*" );
System.setProperty("javax.net.ssl.trustStorePassword", "" );
}
private class DownloadWebPageTask extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... urls) {
TrustManager[] trustAllCerts = new TrustManager[] {
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
}
}
};
try {
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
}
try {
URL url = new URL("https://172.27.224.133");
HttpsURLConnection con =(HttpsURLConnection)url.openConnection();
con.setHostnameVerifier(new AllowAllHostnameVerifier());
finalresponse=readStream(con.getInputStream());
} catch (Exception e) {
e.printStackTrace();
}
return finalresponse;
}
private String readStream(InputStream in) {
BufferedReader reader = null;
try {
reader = new BufferedReader(new InputStreamReader(in));
String line = "";
while ((line = reader.readLine()) != null) {
response+=line;
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (reader != null) {
try {
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return response;
}
@Override
protected void onPostExecute(String result) {
textView.setText(finalresponse);
}
}
public void readWebpage(View view) {
DownloadWebPageTask task = new DownloadWebPageTask();
task.execute(new String[] { "https://172.27.224.133" });
}
}
