Socket s = new Socket("192.168.17.1",8080);
//获取输出流，给服务器发送数据
PrintWriter out = new PrintWriter(s.getOutputStream(),true);
out.println("GET /myapp/font.html HTTP/1.1");
out.println("Accept: */*");
out.println("Host: 192.168.***.***:8080");//Tomcat的默认端口号是8080
out.println("Connection: close");
out.println();
InputStream in = s.getInputStream();
byte[] buf = new byte[1024];
int len = in.read(buf);
String str = new String(buf,0,len);
System.out.println(str);
s.close();
}
