java - 使用套接字发送请求行+文件 - java

Question

我正在尝试通过套接字发送“请求行”和文件。

客户端(发送方)

Socket socket = new Socket(hostName, SOCKET_PORT);
DataOutputStream os = new DataOutputStream(socket.getOutputStream());
FileInputStream fis = new FileInputStream(fileName);
os.writeBytes("PUT c:\dev\foo\helloworld.txt" + "\r\n")
byte[] buffer = new byte[1024];
int bytes;
while((bytes = fis.read(buffer)) != -1 ) {
    try {
        os.write(buffer, 0, bytes);
    } catch (IOException e) {e.printStackTrace();}
}

服务器(接收方)

ServerSocket serverSocket = new ServerSocket(SOCKET_PORT);
Socket clientSoc = serverSocket.accept();
InputStream inputStream = clientSoc.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
String requestLine = bufferedReader.readLine();
File currentFile = (File)new ObjectInputStream(inputStream).readObject(); //This doesn't work
byteSequence = new byte[new Long(currentFile.length()).intValue()];
for(int i =0; i<currentFile.length();i++){
    byteSequence[i] = (byte)clientSoc.getInputStream().read();
} 
try {
    FileOutputStream newFile = new FileOutputStream(currentFile.getName());
    newFile.write(byteSequence,0, byteSequence.length);
} catch (IOException e) {e.printStackTrace();}

我能够读取服务器上的请求行，但是当我尝试读取文件时它会抛出异常(下一行)。

File currentFile = (File)new ObjectInputStream(inputStream).readObject(); 

java.io.Stream.CorruptedException:

java.io.StreamCorruptedException: invalid stream header: 0A48656C

我究竟做错了什么？

您正在尝试访问一个甚至没有传递给套接字的对象。您只传递了一个字节的字符串到服务器，但您从未使用 ObjectOutputStream 将对象传递给服务器。
