java获取百度网盘真实下载链接的方法
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：
importjava.io.BufferedReader;
importjava.io.IOException;
importjava.io.InputStream;
importjava.io.InputStreamReader;
importjava.io.RandomAccessFile;
importjava.lang.reflect.Method;
importjava.net.HttpURLConnection;
importjava.net.URL;
publicclassHttpRequest{
publicstaticStringgetData(Stringu)throwsException{
Stringre="";
URLurl=newURL(u);
HttpURLConnectionhttpURLConnection=(HttpURLConnection)url
.openConnection();
httpURLConnection.setRequestMethod("GET");
httpURLConnection.setDoInput(true);
httpURLConnection.setDoOutput(true);
InputStreamis=httpURLConnection.getInputStream();
InputStreamReaderisr=newInputStreamReader(is);
BufferedReaderbufferedReader=newBufferedReader(isr);
StringiL="";
while((iL=bufferedReader.readLine())!=null){
re+=iL+"\n";
}
returnre;
}
}
