Disable SSL certificate validation of HTTPS connection?
android, httpurlconnection, java, ssl
Solution
Follow the below method, it works for me.
URL url = new URL("Your URL");
HttpsURLConnection urlConnection =(HttpsURLConnection) url.openConnection(); urlConnection.setSSLSocketFactory(SSLCertificateSocketFactory.getInsecure(0, null));
urlConnection.setHostnameVerifier(getHostnameVerifier());
InputStream is = urlConnection.getInputStream();
OutputStream os = new FileOutputStream(downloadedFile);
byte[] data = new byte[1024];
int count;
while ((count = is.read(data)) != -1) {
os.write(data, 0, count);
}
os.flush();
os.close();
is.close();
The below method for set the Hostname
private HostnameVerifier getHostnameVerifier() {
HostnameVerifier hostnameVerifier = new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
HostnameVerifier hv =
HttpsURLConnection.getDefaultHostnameVerifier();
return hv.verify("com.example.com", session);
}
};
return hostnameVerifier;
}
Problem
When I want to open an HTTPS connection I get SSL Exception. How to set HttpURLConnection in a way to doesn't be sensitive to this exception? My code is: ``` private String getData() { String response = null; String connection = "https://www.kamalan.com/"; try { URL url = new URL(connection); Log.i(TAG, "Try to open: " + connection); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); int responseCode = conn.getResponseCode(); Log.i(TAG, "Response code is: " + responseCode); if (responseCode == HttpURLConnection.HTTP_OK) { BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream())); if (in != null) { StringBuilder strBuilder = new StringBuilder(); int ch = 0; while ((ch = in.read()) != -1) strBuilder.append((char) ch); // get returned message and show it response = strBuilder.toString(); Log.i("JSON returned by server:", response); } in.close(); } else { Log.e(TAG, "Couldn't open connection in getResepiItems()"); } } catch (SSLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return response; } ```
