上传时的java EPIPE（断管）？

Question

我的代码有问题，但我不知道E日志报告在哪里

04-08 05:47:46.745: E/Upload Server(20080): Starting  : /storage/sdcard1/Music/Piano (my favourites)/11 Tchaikovsky - The Music Lovers.mp3
04-08 05:47:47.136: E/Upload Server(20080): Connection Error : sendto failed: EPIPE (Broken pipe)

什么是（EPIPE），当我试图上传图片时，它的上传成功了，但任何其他文件E猫报告（管道破裂）为什么

这是我的上传代码

   @Override
    protected String doInBackground(String... urls) {


    String upLoadServerUri = "http://test.com/test.php";
    String fileName = this.file_path;
    HttpURLConnection connection = null;
    DataOutputStream outputStream = null;
    String lineEnd = "\r\n";
    String twoHyphens = "--";
    String boundary = "*****";
    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    int maxBufferSize =  1*1024*1024;
    File sourceFile = new File(fileName);
    int sentBytes = 0;
    long fileSize = sourceFile.length();
    connection = null;


    try
    {


    FileInputStream fileInputStream = new FileInputStream(sourceFile);

    Log.e("Upload Server ", "Starting  : "+ fileName );

    URL url = new URL(upLoadServerUri);
    connection = (HttpURLConnection) url.openConnection();


    connection.setDoInput(true);
    connection.setDoOutput(true);
    connection.setUseCaches(false);
    connection.setChunkedStreamingMode(1024);
    connection.setRequestMethod("POST");
    connection.setRequestProperty("Connection", "Keep-Alive");
    connection.setRequestProperty("Content-Type","multipart/form-data;boundary="+boundary);
    outputStream = new DataOutputStream(connection.getOutputStream() );
    outputStream.writeBytes(twoHyphens + boundary + lineEnd);
    outputStream.writeBytes("Content-Disposition: form-data; name=\"file[]\";filename=\""+ fileName + "\"" + lineEnd);

       outputStream.writeBytes(lineEnd);
       bytesAvailable = fileInputStream.available();
       bufferSize = Math.min(bytesAvailable, maxBufferSize);
       buffer = new byte[bufferSize];



bytesRead = fileInputStream.read(buffer, 0, bufferSize);

   while (bytesRead > 0)
   {

   if(isCancelled()){

   break;
   }

   sentBytes += bytesRead;

   double percentDone = (sentBytes * 1.0) / fileSize * 100;
   publishProgress((int)percentDone);

   outputStream.write(buffer, 0, bufferSize);

   bytesAvailable = fileInputStream.available();

   bufferSize = Math.min(bytesAvailable,     maxBufferSize);
   bytesRead = fileInputStream.read(buffer, 0,      bufferSize);
   }

   if(isCancelled()){

    fileInputStream.close();
   outputStream.flush();
   outputStream.close();
   Log.e("Upload Server ", "upload Canceled " );
   return "canceled";
   }

   outputStream.writeBytes(lineEnd);
   outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
   int serverResponseCode       = connection.getResponseCode();
    fileInputStream.close();
   outputStream.flush();
   outputStream.close();

   if(serverResponseCode == 200)
   {
   Scanner s;
   s = new Scanner(connection.getInputStream());
   s.useDelimiter("\\Z");
   final String response = s.next();
   Log.e("Upload Server ", "Message : " + response);
   return response;
   }else
   {
   Log.e("Upload Server ", "Server Code Error : " + serverResponseCode );
   return "faild";
   }
   }  catch (final Exception e) {

   Log.e("Upload Server ", "Error : " +  e.getMessage() );
   }

   return "falid";
}

请注意，aim在安卓应用程序中仍然更新：） 我在谷歌上搜索了我的问题我找不到解决方案请帮忙

我在使用^{时也遇到了类似的问题。只需添加：

conn.setRequestProperty("connection", "close"); // disables Keep Alive

连接或禁用所有连接：

System.setProperty("http.keepAlive", "false");

从API about disconnect（）：

Releases this connection so that its resources may be either reused or closed. Unlike other Java implementations, this will not necessarily close socket connections that can be reused. You can disable all connection reuse by setting the http.keepAlive system property to false before issuing any HTTP requests.

因此，Android将重用旧的套接字连接。使用上面的代码禁用它可以修复它
