1、HttpClient使用GET方式通过代理服务器读取页面的例子 import java.io.BufferedReader;import java.io.InputStreamReader;import org.apache.http.HttpEntity;import org.apache.http.HttpHost;import org.apache.http.HttpResponse;import org.apache.http.client.methods.HttpGet;import org.apache.http.conn.params.ConnRoutePNames;import org.apache.http.impl.client.DefaultHttpClient; /*** HttpClient使用GET方式通过代理服务器读取页面的例子。** @author JAVA世纪网(, )*/public class HttpClientGet {public static void main(String[] args) throws Exception {DefaultHttpClient httpclient = new DefaultHttpClient();// 访问的目标站点，端口和协议HttpHost targetHost = new HttpHost();// 代理的设置HttpHost proxy = new HttpHost(0, 8080);httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);// 目标地址HttpGet httpget = new HttpGet(/);System.out.println(目标: + targetHost);System.out.println(请求: + httpget.getRequestLine());// 执行HttpResponse response = httpclient.execute(targetHost, httpget);HttpEntity entity = response.getEntity();System.out.println(----------------------------------------);System.out.println(response.getStatusLine());if (entity != null) {System.out.println(Response content length: + entity.getContentLength());}// 显示结果BufferedReader reader = new BufferedReader(new InputStreamReader(entity.getContent(), UTF-8));String line = null;while ((line = reader.readLine()) != null) {System.out.println(line);}if (entity != null) {entity.consumeContent();}}} 2、HttpClient 4 使用POST方式提交普通表单数据的例子 import java.io.BufferedReader;import java.io.InputStreamReader;import org.apache.http.HttpEntity;import org.apache.http.HttpHost;import org.apache.http.HttpResponse;import org.apache.http.client.methods.HttpPost;import org.apache.http.conn.params.ConnRoutePNames;import org.apache.http.entity.StringEntity;import org.apache.http.impl.client.DefaultHttpClient; /*** HttpClient 4 使用POST方式提交普通表单数据的例子.** @author JAVA世纪网(, )*/public class HttpClientPost {public static void main(String[] args) throws Exce
