由于Notepad++里面的文字处理有些复杂，我在想能不能用一个Java程序来统一处理呢？
尝试了一下，发现不太复杂，Java果然处理各种事情都比较方便。程序如下：
注意在RegExp里面，必须用四个反斜杠\代表一个反斜杠
package com.pwc;import java.io.BufferedReader;import java.io.ByteArrayOutputStream;import java.io.DataInputStream;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.net.URL;import java.util.ArrayList;import java.util.regex.Matcher;import java.util.regex.Pattern;public class WechatMomentDownload { public static String jsonFile = "C:Downloadexported_sns_gary.json"; public static String outputFolder = "C:Downloadgary_pic"; public static void main(String[] args) throws IOException { BufferedReader reader = null; String sLine = ""; String sContent = ""; String sLink = ""; URL url = null; String outputFile = ""; ArrayList<String> aLink = new ArrayList<String>(); String Regex1 = "CDATA[http:\/\/(sh)?mmsns([^]]*)/0]"; reader = new BufferedReader( new InputStreamReader(new FileInputStream(new File(jsonFile)), "UTF-8")); if (reader != null) { while ((sLine = reader.readLine()) != null) { sContent = sContent + sLine; } reader.close(); } Pattern pattern = Pattern.compile(Regex1); Matcher matcher = pattern.matcher(sContent); int count = 0; System.out.println("Start processing..."); while(matcher.find()) { count++; sLink = sContent.substring(matcher.start() + 6, matcher.end() - 1); sLink = sLink.replaceAll("\/", "/"); aLink.add(sLink); } System.out.println(count + " pictures were found"); for (String sLinkTemp : aLink) { url = new URL(sLinkTemp); DataInputStream dataInputStream = new DataInputStream(url.openStream()); outputFile = outputFolder + count + ".jpg"; FileOutputStream fileOutputStream = new FileOutputStream(new File(outputFile)); ByteArrayOutputStream output = new ByteArrayOutputStream(); System.out.println("Downloading " + sLinkTemp + " to file " + outputFile); byte[] buffer = new byte[1024]; int length; while ((length = dataInputStream.read(buffer)) > 0) { output.write(buffer, 0, length); } fileOutputStream.write(output.toByteArray()); dataInputStream.close(); fileOutputStream.close(); count--; } System.out.println("End of processing..."); }}更多notepad教程，请访问notepad使用教程栏目：https://www.php.cn/tool/notepad/
