一，導(dǎo)入依賴

org.jsoup

jsoup

1.10.3

org.apache.httpcomponents

httpclient

二，編寫demo類

注意不要導(dǎo)錯(cuò)包了,是org.jsoup.nodes下面的

package com.taotao.entity;

import org.apache.http.HttpEntity;

import org.apache.http.client.methods.CloseableHttpResponse;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.impl.client.CloseableHttpClient;

import org.apache.http.impl.client.HttpClients;

import org.apache.http.util.EntityUtils;

import org.jsoup.Jsoup;

import org.jsoup.nodes.Document;

import org.jsoup.nodes.Element;

import org.jsoup.select.Elements;

import java.io.IOException;

public class intefaceTest {

public static void main(String[] args) throws IOException {

CloseableHttpClient httpClient = HttpClients.createDefault();//創(chuàng)建httpClient

HttpGet httpGet = new HttpGet("http://www.cnblogs.com/");//創(chuàng)建httpget實(shí)例

CloseableHttpResponse response = httpClient.execute(httpGet);//執(zhí)行g(shù)et請(qǐng)求

HttpEntity entity = response.getEntity();//獲取返回實(shí)體

String content = EntityUtils.toString(entity,"utf-8");//網(wǎng)頁(yè)內(nèi)容

response.close();//關(guān)閉流和釋放系統(tǒng)資源

Jsoup.parse(content);

Document doc = Jsoup.parse(content);//解析網(wǎng)頁(yè)得到文檔對(duì)象

Elements elements = doc.getElementsByTag("title");//獲取tag是title的所有dom文檔

Element element = elements.get(0);//獲取第一個(gè)元素

String title = element.text(); //.html是返回html

System.out.println("網(wǎng)頁(yè)標(biāo)題："+title);

Element element1 = doc.getElementById("site_nav_top");//獲取id=site_nav_top標(biāo)簽

String str = element1.text();

System.out.println("str:"+str);

}

}

標(biāo)簽：http,title,入門教程,jsoup,爬取,Jsoup,import,apache,org
