如何用Java实现获取get请求的返回值

需要引用的包

import java.io.IOException;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
import net.sf.json.JSONObject;

编写代码

	public static JSONObject doGetJson(String url) {
		DefaultHttpClient httpClient = new DefaultHttpClient();
		HttpGet httpGet = new HttpGet(url);
		JSONObject jsonObject = null;
		
		try {
			HttpResponse response = httpClient.execute(httpGet);
			HttpEntity entity = response.getEntity();
			if(entity != null) {
				String result = EntityUtils.toString(entity,"UTF-8");
				jsonObject = JSONObject.fromObject(result);
			}
		} catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return jsonObject;
		
	}
