Apache HttpClient 4.1 - Proxy Settings


I am trying to POST some parameters to a server, but I need to set up the proxy. can you help me to to sort it "setting the proxy" part of my code ?

HttpHost proxy = new HttpHost("xx.x.x.xx");

DefaultHttpClient httpclient = new DefaultHttpClient();

httpclient.getParams().setParameter("3128",proxy);


HttpPost httpost = new HttpPost(url);
List<NameValuePair> nvps = new ArrayList<NameValuePair>();

nvps.add(new BasicNameValuePair("aranan", song));

httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));

HttpResponse response = httpclient.execute(httpost);
HttpEntity entity = response.getEntity();
System.out.println("Request Handled?: " + response.getStatusLine());

in = entity.getContent();

httpclient.getConnectionManager().shutdown();

Solution

  • Yes I sorted out my own problem,this line

    httpclient.getParams().setParameter("3128",proxy);
    

    should be

    httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,proxy);
    

    Complete Example of a Apache HttpClient 4.1, setting proxy can be found below

    HttpHost proxy = new HttpHost("ip address",port number);
    DefaultHttpClient httpclient = new DefaultHttpClient();
    httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,proxy);
    
    HttpPost httpost = new HttpPost(url);
    List<NameValuePair> nvps = new ArrayList<NameValuePair>();
    nvps.add(new BasicNameValuePair("param name", param));
    httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.ISO_8859_1));
    HttpResponse response = httpclient.execute(httpost);
    
    HttpEntity entity = response.getEntity();
    System.out.println("Request Handled?: " + response.getStatusLine());
    InputStream in = entity.getContent();
    httpclient.getConnectionManager().shutdown();
