Android使用httpPost向服务器发送请求的方法

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;
 }
}

可以直接用的完整类。

希望本文所述对大家Android程序设计有所帮助。
