HttpClient通过HttpPost传递参数

HttpClient新版本（新老版本没有做明确界定，Sorry!）

package http;

import java.util.ArrayList;
import java.util.List;

import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;

public class HttpTests {

    /**
     * @param args
     * @throws Exception
     */
    public static void main(String[] args) throws Exception {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost("******/abc");
        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        nvps.add(new BasicNameValuePair("username", "vip"));
        nvps.add(new BasicNameValuePair("password", "secret"));
        httpPost.setEntity(new UrlEncodedFormEntity(nvps));
        httpclient.execute(httpPost);
        httpclient.getConnectionManager().shutdown();
    }

}

HttpClient 老版本：

package http;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.PostMethod;

public class HttpTests {

    /**
     * @param args
     * @throws Exception
     */
    public static void main(String[] args) throws Exception {
        HttpClient httpclient = new HttpClient();
        PostMethod httpPost =new PostMethod("******/abc");
        NameValuePair[] param = { new NameValuePair("username", "vip")};
        httpPost.setRequestBody(param);
        httpclient.executeMethod(httpPost);
    }

}
