我正在尝试通过套接字将jar文件发送到服务器。 现在一切似乎工作正常,但在套接字的另一端,jar已损坏。这些文件在套接字的两侧都有相同的长度。但是当我尝试在bukkit中使用该文件时,该文件已损坏。
客户端代码:
public class Main {
private Socket connection;
private ObjectOutputStream outStream;
private static String serverAddress = ""; // the ip address
static File fileLoc = new File("C:\\Users\\Tom\\Documents\\Qubeproject\\server\\plugins");
static String fileName = "\\WorldEdit.jar";
static File file ;
static InputStream IS;
static OutputStream OS;
static byte[] msgByte = new byte[1024];
public static void main(String[] arg0){
p("Starting this shit up");
file = new File(fileLoc + fileName) ;
try {
Socket connection = connection();
IS = connection.getInputStream();
OS = connection.getOutputStream();
OS.write(msg("LOL"));
//Authenciation
IS.read(msgByte);
if(new String(msgByte).trim().equals("OK")){
p("OK");
OS.write(msg(fileName));
//sending fileName
IS.read(msgByte);
p(new String(msgByte).trim());
//confirmation
OS.write(msg("l:" + (file.length())));
byte[] fileByte = new byte[(int)(file.length())];
FileInputStream jis = new FileInputStream(file);
int count = 0;
while((count = jis.read(fileByte))>0){
OS.write(fileByte,0,count);
OS.flush();
}
OS.flush();
setByteZero(msgByte);
IS.read(msgByte);
p(new String(msgByte).trim());
//confirmation
}else{
p("Authenciation failed");
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private static void p (String s){
System.out.println(s);
}
private static byte[] msg(String s){
return s.getBytes();
}
private static Socket connection() throws IOException{
Socket socket = new Socket();
InetAddress ip = InetAddress.getByName(serverAddress);
InetSocketAddress address = new InetSocketAddress(ip,6969);
socket.connect(address,6969);
return socket;
}
private static byte[] setByteZero(byte[] workByte) {
for(int i=0;i < workByte.length;i++){
workByte[i] = 0;
}
return workByte;
}
bukkit中的服务器代码
public class Checkup implements Runnable{
Server serverB;
ServerSocket server;
Socket client;
InputStream IS;
OutputStream OS;
static File destination;
byte[] msgByte = new byte[1024];
String filename;
long length;
Checkup (Server serverm){
serverB = serverm;
}
@Override
public void run() {
try{
server = new ServerSocket(6969);
}catch(Exception e){
}
try{
while(true){
client = server.accept();
IS = client.getInputStream();
OS = client.getOutputStream();
IS.read(msgByte);
if(msg(msgByte).equals("LOL")){
OS.write(msg("OK"));
IS.read(msgByte);
filename = msg(msgByte);
OS.write(msg("Q received name :" + filename));
OS.flush();
setByteZero(msgByte);
IS.read(msgByte);
length = Integer.parseInt(new String(msgByte).trim().replace("l:", ""));
OS.write(msg("Q received length :" + length));
byte[] fileByte = new byte[(int)length];
destination = new File("C:\\Users\\Quentin\\Desktop\\DE server\\plugins" + filename);
FileOutputStream fos = new FileOutputStream(destination);
int count = 0;
while((count =IS.read(fileByte))>0 ){
fos.write(fileByte);
fos.flush();
}
fos.flush();
fos.close();
OS.write(msg("Q received the jar!Bye"));
client.close();
}
}
}catch (Exception e){
e.printStackTrace();
try {
serverB.reload();
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
finally{
}}
private String msg(byte[] strByte){
return new String(strByte).trim();
}
private static byte[] msg(String s){
return s.getBytes();
}
private static byte[] setByteZero(byte[] workByte) {
for(int i=0;i < workByte.length;i++){
workByte[i] = 0;
}
return workByte;
}
答案 0 :(得分:2)
@Jon向你指出了这个问题,这里拼出来并格式化.....
以下代码半忽略计数(并且计数合法也为0):
while((count =IS.read(fileByte))>0 ){
fos.write(fileByte);
fos.flush();
}
fos.flush();
fos.close();
并且应该写成:
while((count =IS.read(fileByte))>=0 ){
fos.write(fileByte, 0, count);
}
fos.flush();
fos.close();
