JAVA代码调用url链接工具类

作为一个菜鸟，记忆下哥们那的方法，顺便方便以后自己调用，算是自己的成长学习记录
调用一个url链接，返回值为String类型字符串：
必备jar包：
commons-logging-1.1.1.jar
httpclient-4.2.5.jar
httpclient-cache-4.2.5.jar
httpcore-4.2.4.jar

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.HttpClient;

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.util.EntityUtils;

public class HttpClientUtil {

public static String get(String url){

HttpClient httpclient = new DefaultHttpClient();

HttpGet httpget = new HttpGet(url);

HttpResponse response = null;

try {

response = httpclient.execute(httpget);

HttpEntity entity = response.getEntity();

return EntityUtils.toString(entity);

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return null;

public static String post(String url){

return EntityUtils.toString(entity);

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return null;

}

public static void main(String[] args) {

System.out.println(HttpClientUtil.post("链接地址"));

}

}
