Java爬虫（三）后台发请求获取页面解析数据

一、发请求获取网页内容

1.我们将请求ascii表网址，处理数据获取表格中的具体内容

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.io.*;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;@RestController
public class SendRequest {@GetMapping("/todo")public String  getsource() {try {//建立连接如ascii表网址 我们获取ascii内容并解析URL url = new URL("http://ascii.911cha.com/");HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setDoInput(true);connection.setRequestMethod("GET");//connection.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)");InputStreamReader read = new InputStreamReader(connection.getInputStream(), "utf-8");//为字符输入流添加缓冲BufferedReader br = new BufferedReader(read);//读取返回结果String data=br.readLine();while (br.readLine() != null) {data =data+br.readLine();}System.out.println(data);// 释放资源br.close();read.close();connection.disconnect();return data;} catch (MalformedURLException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}return null;}
}

得到数据如下

在这里插入图片描述

二、数据解析

我们通过鼠标点击f12开发者模式左上角大概确定了元素的位置，如,那么我们就可以通过正则表达式解析这张表的内容了。
在这里插入图片描述

具体操作如下：

1.截取出这部分代码

  Pattern pattern = Pattern.compile("<tbody>(.*?)(?<dates>.*?)</tbody>");Matcher matcher = pattern.matcher(date);while (matcher.find()){String dates = matcher.group("dates");System.out.println(dates);}

通过这段代码解析后我们得到如下核心数据

<td>0000&#160;0000</td><td align="center">00</td><td align="center" class="xianshi">␀</td></tr><td>0000&#160;0001</td><td align="center">01</td><td align="center"

2.我们再优化下标签，将标签里面的属性去掉

dates =dates.replaceAll("<td().*?>","<td>");
dates =dates.replaceAll("<tr().*?>","<tr>");

得到数据

<td>0000&#160;0000</td><td>00</td><td>␀</td></tr><td>0000&#160;0001</td><td>01</td><td>␁</td></tr><td>0000&#160;0010</td><td>02</td><td>␂</td></tr><td>0000&#160;0011</td><td>03</td><td>␃</td></tr><td>0000&#160;0100</td><td>04</td><td>␄</td></tr><td>0000&#160;0101</td><td>05</td><td>␅</td></tr><td>0000&#160;0110</td><td>06</td><td>␆</td></tr><td>0000&#160;0111</td><td>07</td><td>␇</td></tr><td>0000&#160;1000</td><td>08</td><td>␈</td></tr><td>0000&#160;1001</td><td>09</td><td>␉</td></tr><td>0000&#160;1010</td><td>0A</td><td>␊</td></tr><td>0000&#160;1011</td><td>0B</td><td>␋</td></tr><td>0000&#160;1100</td><td>0C</td><td>␌</td></tr><td>0000&#160;1101</td><td>0D</td><td>␍</td></tr><td>0000&#160;1110</td><td>0E</td><td>␎</td></tr><td>0000&#160;1111</td><td>0F</td><td>␏</td></tr><td>0001&#160;0000</td><td>10</td><td>␐</td></tr><td>0001&#160;0001</td><td>11</td><td>␑</td></tr><td>0001&#160;0010</td><td>12</td><td>␒</td></tr><td>0001&#160;0011</td><td>13</td><td>␓</td></tr><td>0001&#160;0100</td><td>14</td><td>␔</td></tr><td>0001&#160;0101</td><td>15</td><td>␕</td></tr><td>0001&#160;0110</td><td>16</td><td>␖</td></tr><td>0001&#160;0111</td><td>17</td><td>␗</td></tr><td>0001&#160;1000</td><td>18</td><td>␘</td></tr><td>0001&#160;1001</td><td>19</td><td>␙</td></tr><td>0001&#160;1010</td><td>1A</td><td>␚</td></tr><td>0001&#160;1011</td><td>1B</td><td>␛</td></tr><td>0001&#160;1100</td><td>1C</td><td>␜</td></tr><td>0001&#160;1101</td><td>1D</td><td>␝</td></tr><td>0001&#160;1110</td><td>1E</td><td>␞</td></tr><td>0001&#160;1111</td><td>1F</td><td>␟</td></tr><td>0111&#160;1111</td><td>7F</td><td>␡</td></tr></table><table
