Net::SSLeay::Handle - phpMan

NAME
    Net::SSLeay::Handle - Perl module that lets SSL (HTTPS) sockets be
    handled as standard file handles.

SYNOPSIS
      use Net::SSLeay::Handle qw/shutdown/;
      my ($host, $port) = ("localhost", 443);

      tie(*SSL, "Net::SSLeay::Handle", $host, $port);

      print SSL "GET / HTTP/1.0\r\n";
      shutdown(\*SSL, 1);
      print while (<SSL>);
      close SSL;

DESCRIPTION
    Net::SSLeay::Handle allows you to request and receive HTTPS web pages
    using "old-fashion" file handles as in:

        print SSL "GET / HTTP/1.0\r\n";

    and

        print while (<SSL>);

    If you export the shutdown routine, then the only extra code that you
    need to add to your program is the tie function as in:

        my $socket;
        if ($scheme eq "https") {
            tie(*S2, "Net::SSLeay::Handle", $host, $port);
            $socket = \*S2;
        else {
            $socket = Net::SSLeay::Handle->make_socket($host, $port);
        }
        print $socket $request_headers;
        ...

FUNCTIONS
    shutdown
          shutdown(\*SOCKET, $mode)

        Calls to the main shutdown() don't work with tied sockets created
        with this module. This shutdown should be able to distinquish
        between tied and untied sockets and do the right thing.

    debug
          my $debug = Net::SSLeay::Handle->debug()
          Net::SSLeay::Handle->debug(1)

        Get/set debugging mode. Always returns the debug value before the
        function call. if an additional argument is given the debug option
        will be set to this value.

    make_socket
          my $sock = Net::SSLeay::Handle->make_socket($host, $port);

        Creates a socket that is connected to $post using $port. It uses
        $Net::SSLeay::proxyhost and proxyport if set and authentificates
        itself against this proxy depending on $Net::SSLeay::proxyauth. It
        also turns autoflush on for the created socket.

  USING EXISTING SOCKETS
    One of the motivations for writing this module was to avoid duplicating
    socket creation code (which is mostly error handling). The calls to
    tie() above where it is passed a $host and $port is provided for
    convenience testing. If you already have a socket connected to the right
    host and port, S1, then you can do something like:

        my $socket \*S1;
        if ($scheme eq "https") {
            tie(*S2, "Net::SSLeay::Handle", $socket);
            $socket = \*S2;
        }
        my $last_sel = select($socket); $| = 1; select($last_sel);
        print $socket $request_headers;
        ...

    Note: As far as I know you must be careful with the globs in the tie()
    function. The first parameter must be a glob (*SOMETHING) and the last
    parameter must be a reference to a glob (\*SOMETHING_ELSE) or a scaler
    that was assigned to a reference to a glob (as in the example above)

    Also, the two globs must be different. When I tried to use the same
    glob, I got a core dump.

  EXPORT
    None by default.

    You can export the shutdown() function.

    It is suggested that you do export shutdown() or use the fully qualified
    Net::SSLeay::Handle::shutdown() function to shutdown SSL sockets. It
    should be smart enough to distinguish between SSL and non-SSL sockets
    and do the right thing.

EXAMPLES
      use Net::SSLeay::Handle qw/shutdown/;
      my ($host, $port) = ("localhost", 443);

      tie(*SSL, "Net::SSLeay::Handle", $host, $port);

      print SSL "GET / HTTP/1.0\r\n";
      shutdown(\*SSL, 1);
      print while (<SSL>);
      close SSL;

TODO
    Better error handling. Callback routine?

CAVEATS
    Tying to a file handle is a little tricky (for me at least).

    The first parameter to tie() must be a glob (*SOMETHING) and the last
    parameter must be a reference to a glob (\*SOMETHING_ELSE) or a scaler
    that was assigned to a reference to a glob ($s = \*SOMETHING_ELSE).
    Also, the two globs must be different. When I tried to use the same
    glob, I got a core dump.

    I was able to associate attributes to globs created by this module (like
    *SSL above) by making a hash of hashes keyed by the file head1.
