本文详细介绍了如何使用HttpClient类进行Web请求和响应处理，包括构造请求、设置参数、发送请求、接收响应及解析响应内容的过程。通过实例演示了如何发送POST请求，并将请求参数封装为NameValuePair列表，最终打印响应状态和内容。

[b]HttpClientTest.java[/b]


public class HttpClientTest {

	public static void main(String[] args) throws ClientProtocolException, IOException {

		HttpClient client = new DefaultHttpClient();

		try{
			HttpPost post = new HttpPost("http://localhost:8080/sevletTest/page/success.jsp");

			List<NameValuePair> nvps = new ArrayList<NameValuePair>();
			nvps.add(new BasicNameValuePair("username", "Tom"));
			nvps.add(new BasicNameValuePair("password", "12345"));
			HttpEntity entity = new UrlEncodedFormEntity(nvps, "UTF-8");

			post.setEntity(entity);

			System.out.println("Executing Request: " + post.getURI());

			HttpResponse response = client.execute(post);
			entity = response.getEntity();
			System.out.println("Response Status: " + response.getStatusLine());
			if(entity != null){
				System.out.println("Response Content: " + EntityUtils.toString(entity, "UTF-8"));
			}

		}finally{
			client.getConnectionManager().shutdown();
		}

	}
