java获取百度网盘真实下载链接的方法

前端技术 2023/09/03 Java

本文实例讲述了java获取百度网盘真实下载链接的方法。分享给大家供大家参考。具体如下：

目前还存在一个问题，同一ip在获取3次以后会出现验证码，会获取失败，感兴趣的朋友对此可以加以完善。

返回的List<Map<String, Object>>  中的map包含：fileName( 文件名),url(实链地址)

HttpRequest.java如下：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.RandomAccessFile;
import java.lang.reflect.Method;
import java.net.HttpURLConnection;
import java.net.URL;
public class HttpRequest {
 public static String getData(String u) throws Exception {
  String re=\"\";
    URL url = new URL(u);
  HttpURLConnection httpURLConnection = (HttpURLConnection) url
    .openConnection();
  httpURLConnection.setRequestMethod(\"GET\");
  httpURLConnection.setDoInput(true);
  httpURLConnection.setDoOutput(true);
  InputStream is = httpURLConnection.getInputStream();
  InputStreamReader isr = new InputStreamReader(is);
  BufferedReader bufferedReader = new BufferedReader(isr);
  String iL = \"\";
  while ((iL = bufferedReader.readLine()) != null) {
   re += iL + \"\\n\";
  }
  return re;
 }
}

获取方法：

   String fileListJson = HttpRequest.getData(url1);
   System.out.println(fileListJson);
   jsonArray = new JSONArray(\"[\" + fileListJson + \"]\");
   jsonObject = jsonArray.getJSONObject(0);
   jsonArray = new JSONArray(jsonObject.getString(\"list\"));
  }
  final int size = jsonArray.length();
  for (int i = 0; i < size; i++) {
   Map<String, Object> map = new HashMap<String, Object>();
   jsonObject = jsonArray.getJSONObject(i);
   String fileName = jsonObject.getString(\"server_filename\");
   map.put(\"fileName\", fileName);
   fs_id.add(jsonObject.getString(\"fs_id\"));
   String fileInfo = HttpRequest
     .getData(\"http://pan.baidu.com/api/sharedownload?sign=\"

       + fs_id.get(i) + \"%5D\");
   JSONArray jsonArray2 = new JSONArray(\"[\" + fileInfo + \"]\");
   JSONObject json_data = jsonArray2.getJSONObject(0);
   if (json_data.getString(\"errno\").equals(\"0\")) {
    jsonArray2 = new JSONArray(json_data.getString(\"list\"));
    json_data = jsonArray2.getJSONObject(0);
    map.put(\"url\", json_data.getString(\"dlink\"));
   } else if (json_data.getString(\"errno\").equals(\"-20\")) {
    return null;
    // String getVerCode();
   } else {
    return null;
   }
   list.add(map);
  }
  return list;
 }
}
