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 = "
";
    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";
}

请注意在 android 应用中瞄准仍然较新 :)我用谷歌搜索了我的问题，我找不到解决方案，请帮忙！

please note aim still newer in android apps :) i googled my problem i couldn't found a solution please help !

推荐答案

'Broken pipe' 表示你写入的连接已经被对端关闭.

'Broken pipe' means you have written to a connection that has already been closed by the peer.

您可能已超出上传大小限制.

Probably you have exceeded an upload size limit.

您还应该注意，您对 available() 的使用是无效的.Javadoc 中有一个关于 not 以您使用它的方式使用它的特定警告.反正你不需要它:

You should also note that your use of available() is invalid. There is a specific warning in the Javadoc about not using it the way you are using it. You don't need it anyway:

while ((count = in.read(buffer)) > 0)
{
  out.write(buffer, 0, count);
}

其中 buffer 是任何合理的大小，例如8192 字节.

where buffer is any reasonable size, e.g. 8192 bytes.
