I am implementing ResponseCache for HttpUrlConnection in android.
Everything seems to work. I call
ResponseCache.setDefault(new ResCache());
And the methods in my ResCache class are being used as expected. The
only problem I am having is that the Map with request Parameters is
empty. If I try this very same code outside of an android environment,
I will be able to see the request Header parameter, but inside an
activity and all that stuff is not working. Here is the code for the
Activity.
package com.httptest;
import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.CacheRequest;
import java.net.CacheResponse;
import java.net.HttpURLConnection;
import java.net.ResponseCache;
import java.net.URI;
import java.net.URL;
import java.net.URLConnection;
import java.util.List;
import java.util.Map;
import android.app.Activity;
import android.os.Bundle;
public class HttpTest extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ResponseCache.setDefault(new ResCache());
HttpURLConnection urlConnection = null;
try {
URL url = new URL("http://169.254.198.146//patch/500.php";);
urlConnection = (HttpURLConnection) url
.openConnection();
urlConnection.setUseCaches(true);
urlConnection.setRequestProperty("MY_PROPERTY", "MY_VALUE");
InputStream in = new BufferedInputStream(
urlConnection.getInputStream());
String aux = readStream(in);
}catch(Exception e){
e.printStackTrace();
}finally {
urlConnection.disconnect();
}
}
public static String readStream(InputStream in) throws
IOException {
StringBuilder sb = new StringBuilder();
BufferedReader r = new BufferedReader(new InputStreamReader(in),
1000);
for (String line = r.readLine(); line != null; line =
r.readLine()) {
sb.append(line);
}
in.close();
return sb.toString();
}
public class ResCache extends ResponseCache{
@Override
public CacheResponse get(URI arg0, String arg1,
Map<String, List<String>> arg2) throws
IOException {
System.out.println(arg2);
return null;
}
@Override
public CacheRequest put(URI uri, URLConnection connection)
throws IOException {
return null;
}
}
}
In the method ResCache.get(URI, String, Map), the map is always empty.
I would like to see the parameters I added to the request. By the way
the parameters all well set in the request, as I can read them in the
server when performing the request.
Again, this works outside of an android environment.
Any help with this?
Thank you!
