IO::Socket Programming
|
Can't Post

Hello:
I am trying to write a Perl script that will send HTTP requests to a WEB server and
read the server's response using a socket. I
want to read the information to the socket from a flat file. I have been using the example on page 247 of O'Reilly's book "Learning Perl" (the webget client) as a guide.
I have my own web server set up (Apache).
The flat file I want to read, "test2" follows (it is a plain text file named "test2" in my current working directory):
_____________________________________________
PUT /dav/dav/foo.html HTTP/1.1
HOST: liles.raleigh.ibm.com
Content-Type: text/plain
Content-Length: 25
This is so frustrating!!
_____________________________________________
My perl script, "webget.pl", follows:
#############################################
$host = shift(@ARGV);
print "Host is $host\n";
foreach $document ( @ARGV)
{
$remote = IO::Socket::INET->new(
Proto => "tcp",
PeerAddr => $host,
PeerPort => "http(80)",
);
unless ($remote) {die "cannot connect to http deamon on $host"}
$remote->autoflush(1);
print "document = $document\n";
open(DOC, "$document") | |
die "Sorry, I could not find $document\n";
while (@line = <DOC> )
{
foreach $line (@line) {
# print line that was just read
print "line = $line\n";
# send line to socket
print $remote $line;
}
}
# See remote before while loop
print "before while loop: remote = $remote\n";
# hangs in while loop
while ( <$remote> ) {print}
# see if I exit while loop
print "after while remote\n";
close $remote;
}
###########################################
I invoke it as follows:
perl webget.pl liles test2
where "liles" is the host server (Apache webserver) and "test2" is the document file I am reading.
The problem I am having is that is hanging in
the second "while" loop:
(while ( <$remote> ) {print}
I expect to see a file named "foo.html" created on my Web server with the line "This is so frustrating" in it.
I am a total novice to Perl programming.
Any help or suggestions would be appreciated.
