java websocket框架，java socket client_java socket client

用tornado做了個socket server。無奈聯調的人員對接不上。

于是擼出了以下demo

java websocket框架，import java.io.*;

import java.net.*;

public class SocketTest{

java udp socket、SocketTest(){}

void test()

{

java socket發送數據，try{

Socket requestSocket = new Socket("xxx.xxx.xxx.xxx", 60006);

OutputStream out = requestSocket.getOutputStream();

java socket.setkeepalive、InputStream in = requestSocket.getInputStream();

byte[] bb = new byte[16] ;

for(int i =0;i<13;i++)

javasocket編程步驟、{

bb[i+3]=(byte)((int)'a'+i);

}

bb[0]=(byte)0x00;

bb[1]=(byte)0x0e;

bb[2]=(byte)0xaa;

bb[15]=(byte)0xfe;

System.out.println("client>"+new String(bb));

out.write(bb);

out.flush();

byte[] buffer = new byte[1024];

in.read(buffer);

String responseStr = new String(buffer);

System.out.println("server>"+responseStr);

out.close();

in.close();

requestSocket.close();

}

catch(IOException ioException){

ioException.printStackTrace();

}

// catch(ClassNotFoundException classNot){

// System.err.println("data received in unknown format");

// }

}

public static void main(String args[])

{

SocketTest client = new SocketTest();

client.test();

}

}

既要：

1. linux 下編譯執行的細節：

javac SocketTest.java

java SocketTest? (不要 java SocketTest.class, 不然一大堆誤導加麻煩)

2. 字節操作，在java里面用byte數組，不要擔心(128~255)溢出。直接賦值即可。

byte b = (byte)254;

3. 從socket得到原始的輸入輸出流，不要再用其他包裹，否則會出現詭異的事情。

OutputStream out = requestSocket.getOutputStream();

InputStream in = requestSocket.getInputStream();
