NAME
HTTP::LoadGen::Run - HTTP client for HTTP::LoadGen
SYNOPSIS
BEGIN {$ENV{HTTP__LoadGen__Run__dbg}=1} # turn on debugging
use HTTP::LoadGen::Run;
# fetch an URL
$rc=HTTP::LoadGen::Run::run_url $method, $scheme, $host, $port, $uri, $param;
# fetch a list of URLs
HTTP::LoadGen::Run::run_urllist +{times=>10,
before=>sub {...},
after=>sub {...},
InitURLs=>sub {...}};
DESCRIPTION
HTTP::LoadGen::Run
implements the HTTP client for HTTP::LoadGen.
Functions
$rc=HTTP::LoadGen::Run::run_url $method, $scheme, $host, $port, $uri, $param
performs one HTTP request as specified by the parameters. See URLList in HTTP::LoadGen for more information on the parameters.
Note, predelay
and postdelay
specifications are evaluated by HTTP::LoadGen::loadgen(). So, they don't have any effect here.
HTTP::LoadGen::Run::run_urllist \%config
performs a set of HTTP requests one at a time using run_url
. %config
is a hash that may contain these keys:
- InitURLs
-
The value is an iterator generator as described in InitURLs in HTTP::LoadGen.
This value must be a code reference. There are no predefined iterators here.
- times
- before
-
an optional code reference called as
$config->{before}->($rq);
before each request. The
ReqStart
hook in HTTP::LoadGen is implemented this way. - after
-
an optional code reference called as
$config->{before}->($rc, $rq);
after each request. The
ReqDone
hook in HTTP::LoadGen is implemented this way. - dnscache
