SSL双向认证tomcat实现，参考文章如下，其中是使用HttpClient实现的SSL通信。

下面代码使用的是HttpsUrlConnection 实现的SSL 通信。

调用部分：

[java] view plaincopy

private void runHttpsRequestWithHttpsURLConnection(){
AsyncTask <String, Void, String> testTask = new AsyncTask<String, Void, String>() {
@Override
protected String doInBackground(String... params) {
String result = "";

try {
URL url = new URL(HTTPS_URL);
conn = (HttpsURLConnection) url.openConnection();
conn.setSSLSocketFactory(TwoWaysAuthenticationSSLSocketFactory.getSSLSocketFactory(MainActivity.this));
conn.connect();
result = parseSendMessageResponse(conn.getInputStream());
Log.e("HttpsURLConnection Response=====>", result);
return result;
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}catch (NoSuchAlgorithmException e){
e.printStackTrace();
}catch (KeyManagementException e){
e.printStackTrace();
}catch (Exception e){
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
showHttpPage (result);
}
};
testTask.execute();
}
