TCP的客户端功能实现
|
||||||
|
在java中使用一个类Socket表示客户端
|
||||||
|
构造方法:
|
||||||
|
Socket(String host, int port) 创建流套接字并将其连接到指定主机上的指定端口号。
|
||||||
|
|
||||||
|
常用方法:
|
||||||
|
void close() 关闭此套接字。
|
||||||
|
InetAddress getInetAddress() 返回套接字所连接的地址。
|
||||||
|
InputStream getInputStream() 返回此套接字的输入流.(接收响应数据的)
|
||||||
|
OutputStream getOutputStream() 返回此套接字的输出流。 (发送请求)
|
||||||
|
void shutdownOutput() 禁用此套接字的输出流 (设置了一个发送请求数据的结束标记)
|
||||||
|
|
||||||
|
客户端的实现步骤:
|
||||||
|
1.创建客户端对象
|
||||||
|
2.获取字节输出流,发送请求数据
|
||||||
|
3.获取字节输入流,接收响应数据
|
||||||
|
4.释放资源

//1.创建客户端对象

//Socket(String host, int port) 创建流套接字并将其连接到指定主机上的指定端口号。
|
||||||
|
Socket client = new Socket("192.168.22.51", 10001);
|
||||||
|
|
||||||
|
//2.获取字节输出流,发送请求数据
|
||||||
|
OutputStream os = client.getOutputStream();
|
||||||
|
os.write("淘宝的官网".getBytes());
|
||||||
|
|
||||||
|
//3.获取字节输入流,接收响应数据
|
||||||
|
InputStream is = client.getInputStream();
|
||||||
|
//一次读字节数组的方式来读取响应数据
|
||||||
|
byte[] bytes = new byte[1024];
|
||||||
|
int len;
|
||||||
|
while ((len = is.read(bytes)) != -1) {
|
||||||
|
//输出响应结果
|
||||||
|
System.out.println(new String(bytes,0,len));
|
||||||
|
}
|
||||||
|
//4.释放资源
|
||||||
|
client.close();
