数据尚未准备好从Stream读取 [英] Data Not ready to read from Stream

问题描述

我正在尝试从服务器向客户端发送Hello以获得连接...服务器端程序正常运行但客户端代码存在数据尚未准备好读取的问题



这些是我的代码...请帮助...



服务器端：

< pre lang =java>
import java.net。*;
import java.io. *;

public class ServerSide
{
public static void main（ String args []）
{
try
{
ServerSocket ss = new ServerSocket（ 8888 ）;
System.out.println（ Waiting ...）;
Socket server = ss.accept（）;
PrintStream ps = new PrintStream（server.getOutputStream（））;
ps.print（ Hello ...）;
ps.flush（）;
System.out.println（ Data Sent ...）;

}
catch （例外e）
{
System.out.println（ 错误： + e.toString（））;
}
}
}

客户端：< br $> b $ b

  import  java.net。*; 
  import  java.io. *; 
 
  public   class  ClientSide 
 {
  public   static   void  main（ String  args []）
 {
  try  
 {
 字符串 str =  new   String （）; 
套接字客户端=新套接字（InetAddress.getLocalHost（）， 8888 ）; 
 BufferedReader br =  new  BufferedReader（ new  InputStreamReader（client.getInputStream（）））; 
  if （br.ready（））
 {
 str = br.readLine（）; 
 System.out.println（str）; 
} 
  else  
 {
 System.out.println（  数据未准备好从Stream）读取; 
} 
} 
  catch （例外e）
 {
 System.out.println（ 错误： + e.toString（））; 
} 
} 
} 

解决方案

这只是意味着客户端正在尝试从服务器完成其写入功能之前的流。在正常操作中，您的客户端代码应该等待一段时间，然后重新轮询流以查看是否有任何数据出现。

I am trying to send "Hello" from Server to Client on getting connected... Server side program is running properly but Client side code is having a problem that "Data is not ready to read"

These are my codes... Please Help...

Server Side :

import java.net.*;
import java.io.*;

public class ServerSide
{
  	public static void main(String args[])
	{	
	       try
	       {	
        	   ServerSocket ss = new ServerSocket(8888);
		   System.out.println("Waiting...");	
        	   Socket server=ss.accept();
	           PrintStream ps= new PrintStream(server.getOutputStream());
        	   ps.print("Hello...");
	           ps.flush();
		   System.out.println("Data Sent...");
			
	       }
	       catch(Exception e)
	       {
			 System.out.println("Error : " + e.toString());
	       }
	   }
}

Client Side :

import java.net.*;
import java.io.*;

public class ClientSide 
{
	public static void main(String args[])
	{
		try
	       {
		   String str= new String();
	           Socket client=new Socket(InetAddress.getLocalHost(),8888);
        	   BufferedReader br = new BufferedReader(new InputStreamReader(client.getInputStream()));
                   if(br.ready())
                   {
                        str=br.readLine();
        	        System.out.println(str);
                   }
	           else
                   {
                        System.out.println("Data not ready to read from Stream");
                   }
	       }
	       catch(Exception e)
	       {
			System.out.println("Error : " + e.toString());
	       }
	}
}

解决方案

This just means that the client is trying to read from the stream before the server has completed its write function. In normal operation your client code should wait for some short time and then re-poll the stream to see if any data has appeared.
