Summary: Receive binary file from remote machine using libssh2 lib
Initial Comment:
Hi,
I am using libssh2_scp_recv() to write a function to receive files from remote
machine to local machine.
This code is working fine in case of transfering readable (.txt etc) files.
But when any executable binary is received , it is not getting transfered
completely.There may be a problem in reading the contents from the opened
channel.
Function GetFile() code is as follows:
int GetFile(const char *local_path,const char *path,struct stat *sb)
{
long byte = 0 , byte1 = 0;
channel = libssh2_scp_recv(session, path, sb);
printf("Channel returned\n");
if (channel == NULL) {
printf("recv_file(): unable to open channel\n");
try{
char **errmsg;
int *errmsg_len = NULL;
int want_buf;
libssh2_session_last_error(session,
errmsg, errmsg_len , want_buf);
want_buf =
libssh2_session_last_errno(session);
printf("Error String ::
%s",*errmsg);
Conn_UnknownResult;
}catch(...){
}
return (-1);
}
printf("Channel opened\n");
char* buffer = new char[sb->st_size];
QByteArray file_content;
//libssh2_channel_set_blocking(channel, BLOCK);
while(byte < sb->st_size)
{
byte1 =
libssh2_channel_read(channel,buffer,sb->st_size);
byte += byte1;
buffer[byte1] = '\0';
file_content += buffer;
}
QFile file(local_path);
if ((!file.open(QIODevice::WriteOnly)))
{
printf("unable to open file %s\n",local_path);
if (channel) {
libssh2_channel_free(channel);
channel = NULL;
}
return (-1);
}
file.write(file_content);
printf("local file size = %d\n",file.size());
file.close();
if (channel) {
libssh2_channel_free(channel);
channel = NULL;
}
}
Please let me your inputs why this is not working for a binary file.
Thanks,
Regards,
Chamanesh
