使用Groovy进行Socket编程之－普通文本版

服务端代码：

import java.net.ServerSocket
def server = new ServerSocket(9999)

while(true) {
    server.accept { socket ->
        println "\n正在处理新的请求..." 
        socket.withStreams { input, output ->
            def reader = input.newReader()
            char[] msgLength = new char[16];
            reader.read(msgLength, 0, msgLength.length);
            char[] msgBody = new char[Integer.parseInt(String.valueOf(msgLength).trim())];
            reader.read(msgBody, 0, msgBody.length);
            def msg = new String(new String(msgBody).getBytes(), 'UTF-8')  // 此处视客户端编码情况进行字符集转换
            println "获取数据: ${msg}"

//            def buffer = reader.readLine()
            //println "获取数据: ${buffer}"
            //now = new Date()
            //output << "返回数据($now): " + msg + "\n"
        }
        println "线程处理完毕！\n"
    }
}

结果为输出客户端传来的数据。


客户端代码：

s = new Socket("localhost", 4444);
s.withStreams { input, output ->
  output << "echo testing ...\n"
  buffer = input.newReader().readLine()
  println "response = $buffer"
}

groovy应该会自己关闭，如果想程序自己关闭，调用socket.close()
