java中调用HttpGet获取网络服务数据,此处数据以为json数据为例子调用GSon解析json数据,
package com.xxx.biui.util;
import java.io.IOException;
import net.sf.json.JSONObject;
import net.sf.json.util.JSONTokener;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.ParseException;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
public class ControlService{
public static void main(String[] args) throws ParseException, IOException {
String httpUrl = "http://10.120.112.40:8080/bisys/api/bidata/query/user/sindy/history/app?end_time=12/11/25";
HttpGet httpRequest = new HttpGet(httpUrl);
try
{
//取得HttpClient对象
HttpClient httpclient = new DefaultHttpClient();
//请求HttpClient,取得HttpResponse
HttpResponse httpResponse = httpclient.execute(httpRequest);
//请求成功
if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK)
{
//取得返回的字符串
String strResult = EntityUtils.toString(httpResponse.getEntity());
System.out.println(strResult);
JSONObject jo = JSONObject.fromObject(strResult);
/*打印出字段为error的内容*/
System.out.println(jo.get("error"));
}
else
{
;
}
}
catch (ClientProtocolException e1)
{
e1.getMessage().toString();
}}
}
