本文实例讲述了Android使用httpPost向服务器发送请求的方法。分享给大家供大家参考，具体如下：

				?

									import java.util.List;

									import org.apache.http.HttpEntity;

									import org.apache.http.HttpResponse;

									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.conn.ConnectTimeoutException;

									import org.apache.http.impl.client.DefaultHttpClient;

									import org.apache.http.params.CoreConnectionPNames;

									import org.apache.http.protocol.HTTP;

									import org.apache.http.util.EntityUtils;

									import android.util.Log;

									public class RequestByHttpPost {

									  public static String TIME_OUT = "操作超时";

									  public static String doPost(List<NameValuePair> params,String url) throws Exception{

									    String result = null;

									     // 新建HttpPost对象

									     HttpPost httpPost = new HttpPost(url);

									     // 设置字符集

									     HttpEntity entity = new UrlEncodedFormEntity(params, HTTP.UTF_8);

									     // 设置参数实体

									     httpPost.setEntity(entity);

									     // 获取HttpClient对象

									     HttpClient httpClient = new DefaultHttpClient();

									     //连接超时

									     httpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 30000);

									     //请求超时

									     httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 30000);

									     try {

									       // 获取HttpResponse实例

									      HttpResponse httpResp = httpClient.execute(httpPost);

									      // 判断是够请求成功

									      if (httpResp.getStatusLine().getStatusCode() == 200) {

									        // 获取返回的数据

									        result = EntityUtils.toString(httpResp.getEntity(), "UTF-8");

									        Log.i("HttpPost", "HttpPost方式请求成功，返回数据如下：");

									        Log.i("result", result);

									      } else {

									        Log.i("HttpPost", "HttpPost方式请求失败");

									      }

									     } catch (ConnectTimeoutException e){

									       result = TIME_OUT;

									     }

									     return result;

									  }

									}
