HTTP::Server::EV - Asynchronous HTTP server written in C with request parser.
HTTP::Server::EV - Asynchronous HTTP server using EV event loop. It doesn`t load files received in the POST request in memory as moust of CGI modules does, but stores them directly to tmp files, so it`s useful for handling large files without using a lot of memory.
HTTP::Server::EV::CGI - received http request object
HTTP::Server::EV::MultipartFile - received file object
HTTP::Server::EV::Buffer - non blocking output
HTTP::Server::EV::BufTie - workaround for correct handling requests in Coro threads
HTTP::Server::EV::IO::AIO - Non-blocking disk IO.
HTTP::Server::EV::IO::Blocking - Blocking IO.
use EV; use Coro; use HTTP::Server::EV; my $server = HTTP::Server::EV->new; $server->listen(90, sub { my $cgi = shift; $cgi->attach(*STDOUT); $cgi->header; print "Just another Perl server\n"; }); EV::run;
Options:
Directory for saving received files. Tries to create if not found, dies on fail. Default: ./upload_tmpfiles/
Usually HTTP::Server::EV::CGI deletes tmp files on DESTROY, but it might by bug if you delete HTTP::Server::EV::CGI object when its files are still opened. Setting on this flag causes HTTP::Server::EV delete all files in tmp_path on program close, but don`t use it if jou have several process working with same tmp dir. Default: 0
Seting on cause HTTP::Server::EV::CGI parse ip from X-Real-IP http header Default: 0
Binds callback to port. Calls callback and passes HTTP::Server::EV::CGI object in it. Returns HTTP::Server::EV::PortListener obeject, you can keep it and use to stop port listening.
$server->listen( 8080 , sub { my $cgi = shift; $cgi->attach(local *STDOUT); # attach STDOUT to socket $cgi->header; # print http headers to stdout print "Test page"; }); $server->listen( 8080 , sub { #req_received_callback my $cgi = shift; $cgi->attach(local *STDOUT); # attach STDOUT to socket $cgi->header; # print http headers to stdout print "Test page"; }, { threading => 1, # run every req_received_callback in Coro thread. "use Coro;" first timeout => 1*60 , # server drops request if there is no activity on socket after "timeout" sec. 1min default. Set 0 to disable #This is for not fully received requests, received requests aren't affected and you can keep request object with socket as long as you need it. fork_hook => sub { # do preforking here if you want. Forking more than 1 process per core may be inefficient if you app fully asynchronous. HTTP::Server::EV is fully asynchronous itself if uses IO::AIO }, #multipart processing callbacks # you needn't specify all callbacks on_multipart => sub { my ($cgi) = @_; # called on multipart body receiving start }, on_file_open => sub { my ($cgi, $multipart_file_obj ) = @_; # called on multipart file receiving start }, on_file_write => sub { my ($cgi, $multipart_file_obj, $data_chunk ) = @_; # called when file part written to disk. # useful for on flow calculting hashes like md5 # or just to know progress by reading $multipart_file_obj->{size} }, on_file_received => sub { my ($cgi, $multipart_file_obj) = @_; # called on file writing done }, on_error => sub { my ($cgi) = @_; # called when server drops multipart post connection. # also called when you manually reject connection by calling $cgi_obj->drop; }, });
Delete all files in tmp_path. Automatically called on DESTROY if cleanup_on_destroy set
Static allocated buffers:
- 4kb for GET/POST form field names
- 4kb for GET values
- 50kb for POST form field values ( not for files. Files are stored into tmp directly from socket stream, so filesize not limited by HTTP::Server::EV)
HTTP::Server::EV drops connection if some buffer overflows. You can change these values in EV.xs and recompile module.
