首先在有道云笔记里写文章，再用下列Java工具将文章所有的图片下载到本地：
package youdao;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import org.json.JSONObject;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
public class YoudaoNoteSingle {
private static String mTitle = null; private static final String PREFIX = "C:\\Users\\i042416\\Pictures\\";
private static void createFolder(String title){ DownloadTask.FOLDER = PREFIX + title; File file = new File( DownloadTask.FOLDER); file.mkdir();}
private static List<DownloadTask> getYoudaoPicUrlList(String formattedUrl){
HttpClient client = HttpClients.createDefault(); List<DownloadTask> resultPic = new ArrayList<DownloadTask>(); int index = 0;
HttpGet get = new HttpGet(formattedUrl); try {
HttpResponse response = client.execute(get); HttpEntity entity = response.getEntity();
String result = EntityUtils.toString(entity, "UTF-8"); JSONObject obj = new JSONObject(result);
mTitle = obj.get("tl").toString(); createFolder(mTitle); String content = obj.get("content").toString();
Matcher m = Pattern.compile("src\\s*=\\s*\"?(.*?)(\"|>|\\s+)").matcher(content);
while (m.find()) { DownloadTask task = new DownloadTask(m.group(1), index++); resultPic.add(task); } } catch (Exception e){ e.printStackTrace(); }
return resultPic; } private static void start(List<DownloadTask> task){
if( task.isEmpty()){System.out.println("No picture to download!"); return;}
System.out.println("Total pic to be downloaded: " + task.size()); ExecutorService executor = Executors.newFixedThreadPool(10);
for( int i = 0; i < task.size(); i++){PictureDownloader cc = new PictureDownloader(task.get(i)); executor.execute(cc);}executor.shutdown();
while (!executor.isTerminated()) {} System.out.println("Download Finished.");} private static void download(){
String zero = "c91a710af51c1e1b20f5d1da2140a9e4"; String one = "4cc557ab9b7cbde0515b49a155c5dce3"; String two = "6eaae532daaa678cc610f2a34cbc9119"; String urlStr = "";
/***************/ int YOUR_CHOICE = 2; /************/ switch(YOUR_CHOICE){
case 0: urlStr = "http://note.youdao.com/yws/public/note/" + zero + "?keyfrom=public"; break;
case 1: urlStr = "http://note.youdao.com/yws/public/note/" + one + "?keyfrom=public"; break;
case 2: urlStr = "http://note.youdao.com/yws/public/note/" + two + "?keyfrom=public"; break; }
System.out.println("url: " + urlStr); List<DownloadTask> task = getYoudaoPicUrlList(urlStr); start(task);}
public static void main(String[] args) {download(); }}文章里的图片用[图片]代替。
然后在使用这个html网页，将云笔记的文章源代码里包含的[图片]转换成markdown格式：
<html id="whole">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Jianshu Publish Tool</title>
<link rel="shortcut icon" type="image/png" href="d3.png" />
</head>
<style>
#raw, #result {
background-color: rgb(199,237,204);
}
#whole {
background-color: black;
}
</style>
<textarea id="raw" rows="70" cols="80" onkeydown="keySend(event);">
</textarea>
<textarea id="result" rows="70" cols="80">
Paste the raw string copied from Cloud note in the Raw area
</textarea>
<button id="jerrybutton" onclick="myFunction()">Click me</button>
<script>
function keySend(event) {
if (event.ctrlKey && event.keyCode == 13) {
var button=document.getElementById("jerrybutton");
button.focus();
button.onclick();
}
}
