【Android】基于TCP协议的网络通信

ServerSocket server;
try {
server = new ServerSocket(8000);
while (true) {
Socket client = server.accept(); // 等待客户端的请求
OutputStream stream = client.getOutputStream();
stream.write("hello world!\n".getBytes("utf-8"));// 发送消息
stream.close();
client.close();
}
}
catch (Exception ex) {
ex.printStackTrace();
}

Socket client;
try {
// 创建客户端并建立远程连接，具体IP地址和端口号需根据实际情况而定
client = new Socket("192.168.1.94", 8000);
// 将接受到的输入流封装成BufferedReader
BufferedReader reader = new BufferedReader(
new InputStreamReader(client.getInputStream()));
String msg = reader.readLine();
Log.w("TCP", msg);
reader.close();
client.close();
}
catch (Exception ex) {
ex.printStackTrace();
}
