前言
近期本人在某云上购买了个人域名,本想着以后购买与服务器搭建自己的个人网站,由于需要筹备的太多,暂时先搁置了,想着先借用GitHub Pages搭建一个静态的站,搭建的过程其实也曲折,主要是域名地址配置把人搞废了,不过总的来说还算顺利,网站地址 https://chenchangyuan.cn(空博客,样式还挺漂亮的,后期会添砖加瓦)
利用git npm hexo,再在github中进行相应配置,网上教程很多,如果有疑问欢迎评论告知。
本人以前也是搞过几年java,由于公司的岗位职责,后面渐渐地被掰弯,现在主要是做前端开发。
所以想利用java爬取文章,再将爬取的html转化成md(目前还未实现,欢迎各位同学指导)。
1.获取个人博客所有url
查看博客地址https://www.cnblogs.com/ccylovehs/default.html?page=1
根据你自己写的博客数量进行遍历
将博客的详情页地址存放在set集合中,详情页地址https://cloud.tencent.com/developer/article/1339307
2.详情页url生成html文件
遍历set集合,依次生成html文件
文件存放在C://data//blog目录下,文件名由捕获组1生成
3.代码实现
代码语言:javascript复制package com.blog.util;
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Iterator;
import java.util.Set;
import java.util.TreeSet;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
/**
* @author Jack Chen
* */
public class BlogUtil {
/**
* URL_PAGE:cnblogs url
* URL_PAGE_DETAIL:详情页url
* PAGE_COUNT:页数
* urlLists:所有详情页url Set集合(防止重复)
* p:匹配模式
* */
public final static String URL_PAGE = "https://www.cnblogs.com/ccylovehs/default.html?page=";
public final static String URL_PAGE_DETAIL = "https://www.cnblogs.com/ccylovehs/p/([0-9] .html)";
public final static int PAGE_COUNT = 3;
public static Set<String> urlLists = new TreeSet<String>();
public final static Pattern p = Pattern.compile(URL_PAGE_DETAIL);
public static void main(String[] args) throws Exception {
for(int i = 1;i<=PAGE_COUNT;i ) {
getUrls(i);
}
for(Iterator<String> i = urlLists.iterator();i.hasNext();) {
createFile(i.next());
}
}
/**
* @param url
* @throws Exception
*/
private static void createFile(String url) throws Exception {
Matcher m = p.matcher(url);
m.find();
String fileName = m.group(1);
String prefix = "C://data//blog//";
File file = new File(prefix fileName);
PrintStream ps = new PrintStream(file);
URL u = new URL(url);
HttpURLConnection conn = (HttpURLConnection) u.openConnection();
conn.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(), "utf-8"));
String str;
while((str = br.readLine()) != null){
ps.println(str);
}
ps.close();
br.close();
conn.disconnect();
}
/**
* @param idx
* @throws Exception
*/
private static void getUrls(int idx) throws Exception{
URL u = new URL(URL_PAGE "" idx);
HttpURLConnection conn = (HttpURLConnection) u.openConnection();
conn.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(), "utf-8"));
String str;
while((str = br.readLine()) != null){
if(null != str && str.contains("https://www.cnblogs.com/ccylovehs/p/")) {
Matcher m = p.matcher(str);
if(m.find()) {
System.out.println(m.group(1));
urlLists.add(m.group());
}
}
}
br.close();
conn.disconnect();
}
}
4.结语
如果觉得对您有用的话,麻烦动动鼠标给我一颗star,您的鼓励是我最大的动力

由于不想一篇篇的手动生成md文件,下一步需要将html文件批量的转化成md文件,以便完善个人博客内容,未完待续~~~
