如果文件大于 12MB 大于块发送的文件，我正在尝试在客户端-服务器之间传输文件，否则它会正常发送。我的主要问题是每次我传输的东西都会比原来的字节多，我需要在完成后使用摘要消息，所以它不会按原样工作，另一个是当我尝试发送文件时通过网络，客户端读取要发送的文件比服务器写入它的速度更快，因此客户端关闭程序关闭连接，从而损坏文件。我的转移代码如下：
这是客户端转移代码：
if(fSize>maxfileSize){
totbLidos = 0;
byte[] fBytes = new byte[fBsize];
while(totbLidos < fSize){
int bRemain = (int) f.length() - totbLidos;
if(bRemain < fBsize){
fBsize = bRemain;
}
int bRead = tFile.read(fBytes, 0, fBsize);
tServidor.write(fBytes, 0, fBsize);
tServidor.flush();
if(bRead>0){
totbLidos+=bRead;
}
System.out.println("Total Bytes Lidos: " + totbLidos);
}
tFile.close();
System.out.println("Ficheiro enviado");
cliente.close();
}
else{
totbLidos = 0;
byte[] fBytes = new byte[fSize];
while(totbLidos < fSize){
int bRead = tFile.read(fBytes,0,fSize);
if(bRead>0){
totbLidos+=bRead;
}
tServidor.write(fBytes, 0, fSize);
System.out.println("Total Bytes Lidos: " + totbLidos);
tServidor.flush();
}
tFile.close();
System.out.println("Ficheiro enviado");
cliente.close();
}
}
服务器传输代码：
if(fSize > maxfileSize){
totbLidos = 0;
DataInputStream tFile = new DataInputStream(cliente.getInputStream());
BufferedOutputStream fos = new BufferedOutputStream(new FileOutputStream(fName));
byte[] fBytes = new byte[fBsize];
while(totbLidos < fSize){
int bRemain = size - totbLidos;
if(bRemain < fBsize){
fBsize = bRemain;
}
int bRead = tFile.read(fBytes, 0, fBsize);
fos.write(fBytes);
fos.flush();
if(bRead>0){
totbLidos+=bRead;
}
System.out.println("Bytes lidos: " + bRead);
System.out.println("Total Bytes Escritos: " + totbLidos);
}
System.out.println("Ficheiro recebido");
fos.close();
tFile.close();
cliente.close();
servidor.close();
}
else if(fSize < maxfileSize){
totbLidos = 0;
DataInputStream tFile = new DataInputStream(cliente.getInputStream());
BufferedOutputStream fos = new BufferedOutputStream(new FileOutputStream(fName));
byte[] fBytes = new byte[fSize];
while(totbLidos < fSize){
int bRead = tFile.read(fBytes,0,fSize);
fos.write(fBytes);
fos.flush();
if(bRead>0){
totbLidos+=bRead;
}
System.out.println("Total Bytes Escritos: " + totbLidos);
}
System.out.println("Ficheiro recebido");
fos.close();
tFile.close();
cliente.close();
servidor.close();
}
}
