本文實例講述了java獲得百度網盤真實下載鏈接的辦法。分享給年夜家供年夜家參考。詳細以下：

今朝還存在一個成績，統一ip在獲得3次今後會湧現驗證碼，會獲得掉敗，感興致的同伙對此可以加以完美。

前往的List<Map<String, Object>>  中的map包括：fileName( 文件名),url(實鏈地址)

HttpRequest.java以下：

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;
 }
}

獲得辦法：
