How do I add query string to HttpMethod?
Category: commons.httpclient, viewed: 4832 time(s).
To send query string information in HTTP GET command you either using passing a simple string or an array of NameValuePair object into the HttpMethod's setQueryString() method. We also need to encode the parameter values before passing it to the method.
package org.kodejava.example.commons.httpclient;
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.util.URIUtil;
import org.apache.commons.httpclient.methods.GetMethod;
import java.io.IOException;
public class SendingQueryParameter {
public static void main(String[] args) {
HttpClient client = new HttpClient();
HttpMethod method = new GetMethod("http://www.kodejava.org/browse.php");
try {
//
// Set query string information for accessing the page using a
// simple string information.
//
method.setQueryString(URIUtil.encodeQuery("catid=47&page=1"));
//
// Other cleaner alternative is to use the NameValuePair object to
// define the parameters for a HTTP GET method.
//
NameValuePair param1 = new NameValuePair("catid", URIUtil.encodeQuery("47"));
NameValuePair param2 = new NameValuePair("page", URIUtil.encodeQuery("1"));
NameValuePair[] params = new NameValuePair[] {param1, param2};
method.setQueryString(params);
client.executeMethod(method);
} catch (URIException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
method.releaseConnection();
}
}
}
