Thank you very much for your reply .
My server running on centos 7.5 . And client running on windows 10
.
The data seems be cached on the server and not be sent out. Dose
centos have the same problem?
I'm not sure what the problem is .
I would really appreciate if you have any Suggestions.

SRU-28.

I'm
using openssl as client in blocking mode , i have a problem .
Sometimes
my program can't receive data , and acctually server has been
sent the data to me.
I
can only receive the data by sending another request . Then the data
i expected arrived with a new data sent by server .
------------------------------------------------------------------------------
bool
can_read()
{
if(SSL_pending(m_ssl)) return
true; struct
timeval tv = {0 , 100};
FD_ZERO(&m_rfds);
FD_SET(m_socket.fd(),
&m_rfds);
int
ret = select( m_socket.fd()+1, &m_rfds , NULL, NULL, &tv);
return
ret > 0 ;
} //this
is the main process
int
try_receive(char * buf , int len )
{
if(
!can_read())
return
-1;
return
SSL_read(m_ssl, buf, len);
}
-------------------------------------------------------------------------------
Above
is my code , my program get `false` from `can_read`
although the server has sent response data
I really appreciate your help. |
