2.使用org.apache.http.client.HttpClient访问网络

一个是操作类，一个是junit test类，直接上代码：

org.apache.http.client.HttpClient.java

package org.example.httpclient;import java.util.ArrayList;import java.util.List;import org.apache.http.HttpEntity;import org.apache.http.HttpResponse;import org.apache.http.HttpStatus;import org.apache.http.NameValuePair;import org.apache.http.client.HttpClient;import org.apache.http.client.entity.UrlEncodedFormEntity;import org.apache.http.client.methods.HttpGet;import org.apache.http.client.methods.HttpPost;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.message.BasicNameValuePair;import org.apache.http.util.EntityUtils;public class MHttpClient {    public void get() throws Exception {        // 创建HttpClient实例        HttpClient client = new DefaultHttpClient();        // 根据URL创建HttpGet实例        HttpGet get = new HttpGet("http://192.168.1.132:8088/WebServer/student.do");        // 执行get请求，得到返回体        HttpResponse response = client.execute(get);        // 判断是否正常返回        if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {            // 解析数据            String data = EntityUtils.toString(response.getEntity());            System.out.println(data);        }    }    public void post() throws Exception {        // 创建HttpClient实例        HttpClient client = new DefaultHttpClient();        // 根据URL创建HttpPost实例        HttpPost post = new HttpPost("http://192.168.1.132:8088/WebServer/student.do");        // 构造post参数        List<NameValuePair> params = new ArrayList<NameValuePair>();        params.add(new BasicNameValuePair("name", "11"));        // 编码格式转换        UrlEncodedFormEntity entity = new UrlEncodedFormEntity(params);        // 传入请求体        post.setEntity(entity);        // 发送请求，得到响应体        HttpResponse response = client.execute(post);        // 判断是否正常返回        if (response.getStatusLine().getStatusCode() == 200) {            // 解析数据            HttpEntity resEntity = response.getEntity();            String data = EntityUtils.toString(resEntity);            System.out.println(data);        }    }}

MHttpClientTestCast.java

package org.example.httpclient;import android.test.AndroidTestCase;public class MHttpClientTestCast extends AndroidTestCase {    public void testGet() throws Exception {        MHttpClient client = new MHttpClient();        client.get();    }    public void testPost() throws Exception {        MHttpClient client = new MHttpClient();        client.post();    }}

和URL对比了一下，感觉就是封装了底层的流操作
