Android SSL HttpGet (No peer certificate) error OR (Connection closed by peer) error
I am trying to do a simple HttpGet to read a webpage. I have this working on iOS and working on Android over http, but not https.
The url is an internal network IP and custom port, so I can read with http like this using a path of http://ipaddress:port/MyPage.html
HttpClient httpclient = new DefaultHttpClient(httpParameters);
HttpResponse response;
String responseString = null;
try {
// Try connection
HttpGet get = new HttpGet(params[0].path);
get.addHeader("Authorization",
"Basic "
+ Base64.encodeBytes(new String(params[0].username + ":" + params[0].password)
.getBytes()));
response = httpclient.execute(get);
StatusLine statusLine = response.getStatusLine();
if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.getEntity().writeTo(out);
out.close();
responseString = out.toString();
} else {
// Closes the connection.
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());
}
} catch (ClientProtocolException e) {
Log.e(TAG, "ClientProtocolException");
this.e = e;
} catch (IOException e) {
Log.e(TAG, "IOException");
this.e = e;
}
return responseString;
When I try using https, I get the No peer certificate error. So I have tried using this code:
HttpClient httpclient = new DefaultHttpClient(httpParameters);
private HttpClient createHttpClient() {
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.DEFAULT_CONTENT_CHARSET);
HttpProtocolParams.setUseExpectContinue(params, true);
SchemeRegistry schReg = new SchemeRegistry();
schReg.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
schReg.register(new Scheme("https", sf, 8080));
ClientConnectionManager conMgr = new ThreadSafeClientConnManager(params, schReg);
return new DefaultHttpClient(conMgr, params);
} catch (Exception e) {
return new DefaultHttpClient();
}
}
but this gives me a Connection closed by peer error.
What am I doing wrong? I can safely ignore the certificate, as it's an internal network with self signed cert, however I have no control over the vert and users of my app may have different certs, so I really need to auto accept or bypass it.
Thanks
EDIT ------------------------------
After trying My-Name-Is answer below: I've created a CustomX509TrustManager class as suggested, then create a custom HttpClient using it like this:
private HttpClient sslClient(HttpClient client) {
try {
CustomX509TrustManager tm = new CustomX509TrustManager();
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(null, new TrustManager[] { tm }, null);
SSLSocketFactory ssf = new MySSLSocketFactory(ctx);
ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = client.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", ssf, 8080));
return new DefaultHttpClient(ccm, client.getParams());
} catch (Exception ex) {
return null;
}
}
And finally use this HttpClient like this:
private class httpGETTask extends AsyncTask<GetParams, Void, String> {
private Exception e = null;
@Override
protected String doInBackground(GetParams... params) {
// Set connection parameters
HttpParams httpParameters = new BasicHttpParams();
int timeoutConnection = 15000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
int timeoutSocket = 15000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
Log.v(TAG, params[0].path);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
httpclient = sslClient(httpclient);
HttpResponse response;
String responseString = null;
try {
// Try connection
HttpGet get = new HttpGet(params[0].path);
get.addHeader("Authorization",
"Basic "
+ Base64.encodeBytes(new String(params[0].username + ":" + params[0].password)
.getBytes()));
response = httpclient.execute(get);
StatusLine statusLine = response.getStatusLine();
if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.getEntity().writeTo(out);
out.close();
responseString = out.toString();
} else {
// Closes the connection.
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());
}
} catch (ClientProtocolException e) {
Log.e(TAG, "ClientProtocolException");
this.e = e;
} catch (IOException e) {
Log.e(TAG, "IOException");
this.e = e;
}
return responseString;
The logged path is in the format https://ipaddress:8080/Page.html
But I get a Connection closed By Peer error:
