什么是(EPIPE)? ,当我尝试成功上传图片上载的,但任何其他文件Ë猫报告(断管)为什么!
what is (EPIPE) ? , when i attempt to upload image its upload successfully but any other file E Cat report (Broken pipe) why !
这是我上传code
@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";
}
请注意目标在Android应用程序还是新的:) 我GOOGLE了我的问题,我无法找到一个解决方案,请大家帮忙!
please note aim still newer in android apps :) i googled my problem i couldn't found a solution please help !
破碎管是指你写一个已被关闭对端的连接。
'Broken pipe' means you have written to a connection that has already been closed by the peer.
也许你已经超过了上传大小限制。
Probably you have exceeded an upload size limit.
您也应该注意,您使用可供选择()
是无效的。有大约在的没有的Javadoc中一个特定的警告使用它,你正在使用它的方式。你不需要也无妨:
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,缓存
是任何合理的大小,如8192字节。
where buffer
is any reasonable size, e.g. 8192 bytes.
