使用RECV接收部分数据包 [英] Receiving partial Packets using RECV

问题描述

你好，

我已经编写了一段代码，但是无法正常工作

Hello,

I have made myself a piece of code, but it is not working correctly

$socket->send($sPacket);
($msg) = '';
recv($socket, $msg, 10, 0) or die "recv: $!"; #This line
if($msg != NULL)
{
    recv($socket, $msg2, 5, 0) or die "recv: $!"; #This line
    if($msg2 == 'p4150')
    {
        print "Successfully connected to the server.";
    }
    else
    {
        print "FAILB : $msg2";
    }
}
else
{
    print "FAILA : $msg";
}

这是行不通的，因为RECV(带有标志0)希望有一个至少具有接收数据包大小的缓冲区.数据包的长度为15，我只希望前10位，然后第二个RECV上的后5位.
我可以使用任何标志来解决此问题，还是有一个好的选择(其他接收功能/其他功能)?

提前谢谢！，
Tim

It doesn''t work because RECV(with flags 0) wants be to have a buffer of at least the size of the receiving packet. The packet has a length of 15 , I want only the first 10 bits and then the next 5 on the second RECV.
Are there any flags I can use to solve this problem, or is there a good alternative (other receiving function/something else)?

Thanks in advance!,
Tim

推荐答案

socket -> send(

socket->send(

sPacket )； (

sPacket); (

msg )= '

msg) = ''; recv(
