DataInputStream里的readByte()读出来是乱码
public String send(String Command) throws Exception { String ret=""; Socket soc = new Socket(getURL(), getPORT());//getURL=192.168.1.168；getPORT=4016 System.out.println("Connect Telnet:" + getURL() + "-" + getPORT()); DataInputStream din = new DataInputStream(soc.getInputStream()); DataOutputStream dout = new DataOutputStream(soc.getOutputStream()); dout.writeUTF(Command); System.out.println("send:" + Command); int re=0; while (re != -1) { re = din.readByte();//read（）；readInt（）；readUTF（）；方法都试了结果都不对 System.out.println("int" + re); Character c = new Character((char) re);//这就开始乱码了 System.out.println("char:" + c); ret = ret.concat(c.toString()); } System.out.println("reply:" + ret); din.close(); dout.close(); soc.close(); return ret; }StringBuffer sb = new StringBuffer(); int len = 0; byte[] buffer = new byte[4096]; while ((len = din.read(buffer)) != -1) { sb.append(new String(buffer,0,len,"UTF-8")); } System.out.println(sb.toString());
