以下代码基于httpclient3.1

public class HttpClientTest {    public static void main(String args[]) throws Exception {        HttpClient httpClient = new HttpClient();        String url = "http://localhost:8080/wm/index.jsp";        PostMethod postMethod = new PostMethod(url);        // 填入各个表单域的值        NameValuePair[] data =new NameValuePair[]{new NameValuePair("uname","zhang san")};        // 将表单的值放入postMethod中        postMethod.setRequestBody(data);       // postMethod.addParameter("uname", "zhang san");一样的效果         postMethod.setRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 5.1; rv:8.0) Gecko/20100101 Firefox/8.0");        // 执行postMethod        httpClient.executeMethod(postMethod);        System.out.println(postMethod.getResponseBodyAsString());        postMethod.releaseConnection();    }}
