Proxy with optional basic authentication. We have a ServerComm class
that contains server connection info. You should be
able to figure out what it is doing.
---> START
DefaultHttpClient cli = new DefaultHttpClient();
HttpGet method = null;
HttpHost targetHost = null;
HttpHost proxy = null;
if (ServerComm.UseProxy )
{
if ( ServerComm.UseProxyAuth)
{
cli.getCredentialsProvider().setCredentials(
new AuthScope(ServerComm.ProxyAddress,
ServerComm.ProxyPort),
new
UsernamePasswordCredentials(ServerComm.ProxyUser, ServerComm.ProxyPw)
);
}
targetHost = new HttpHost(ServerComm.GetServerSite(),
ServerComm.ServerPort, ServerComm.Method);
proxy = new HttpHost(ServerComm.ProxyAddress, ServerComm.ProxyPort);
cli.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
try {
URI newUri = new URI(ServerComm.GetServerUrl());
method = new HttpGet(newUri.getRawPath() + "?" +
newUri.getRawQuery());
} catch (URISyntaxException ex) {
System.out.println("URI Encode Error " + ex.toString());
isCorrect = false;
return false;
}
}
else
{
method = new HttpGet(ServerComm.GetServerUrl());
}
HttpResponse resp = null;
HttpEntity ent = null;
method.addHeader("User-Agent", ServerComm.MDOUserAgent);
//execute the method
String responseBody = null;
try{
if (ServerComm.UseProxy )
{
resp = cli.execute(targetHost,method);
}
else
{
resp = cli.execute(method);
}
ent = resp.getEntity();
}
