使用socket接收数据为空

String result ="";

try {

inputStream =socket.getInputStream();

DataInputStream input =new DataInputStream(inputStream);

int count =0;

while (count ==0) {

count = input.available();

}

byte[] b =new byte[count];

int len = input.read(b);

result =new String(b,0, len);

parseString(result);//解析得到的字符串

}catch (Exception e) {

e.printStackTrace();

}finally {

disConnSocket();//断开连接

}
