import org.apache.http.HttpEntity;
import org.apache.http.client.ClientProtocolException;

public class HttpClient {
	public static void main(String[] args) throws ClientProtocolException, IOException {
		String url="http://www.weather.com.cn/weather/101010100.shtml";
		//1.使用默认的配置的httpclient
		CloseableHttpClient client = HttpClients.createDefault();
		//2.使用get方法
		HttpGet httpGet = new HttpGet(url);
		//3.执行请求，获取响应
		CloseableHttpResponse response = client.execute(httpGet);
		//4.获取响应的实体内容，就是我们所要抓取得网页内容
		HttpEntity entity = response.getEntity();
		//5.将其打印到控制台上面
		if (entity != null) {
			System.out.println(EntityUtils.toString(entity, "utf-8"));
		}
