【问题描述】:
我是网络新手,在尝试运行 MyClient.java 时遇到 EOFException。
MyServer.java
public class MyServer {
public static void main(String[] args) {
ServerSocket serverSocket = null;
try {
serverSocket = new ServerSocket(4321);
} catch (IOException e) {
e.printStackTrace();
}
while(true) {
try {
Socket socket = serverSocket.accept();
OutputStream os =socket.getOutputStream();
OutputStreamWriter osw = new OutputStreamWriter(os);
BufferedWriter bw = new BufferedWriter(osw);
bw.write("Hello networking");
bw.close();
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
MyClient.java
public class MyClient {
public static void main(String[] args) {
Socket socket = null;
try {
socket = new Socket("127.0.0.1", 4321);
InputStream is = socket.getInputStream();
DataInputStream dis = new DataInputStream(is);
System.out.println(dis.readUTF());
dis.close();
socket.close();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (ConnectException e) {
System.err.println("Could not connect");
} catch (UTFDataFormatException e) {
System.err.println("if the bytes do not represent a valid modified UTF-8 encoding of a string");
} catch (EOFException e) {
System.err.println("if this input stream reaches the end before reading all the bytes");
} catch (IOException e) {
e.printStackTrace();
}
}
}
我得到如果此输入流在读取错误的所有字节之前到达末尾,并且错误似乎是由 dis.readUTF() 调用引起的。
有人可以帮助我了解我缺少什么吗?我正在尝试读取服务器在连接时向客户端写入的内容,即 Hello network。
谢谢。
