NAME

Net::Curl::Easier - Convenience wrapper around Net::Curl::Easy

SYNOPSIS

    my $easy = Net::Curl::Easier->new( url => 'http://perl.org' )->perform();

    print $easy->body();

    # … or, to dig in to the response:
    my $response = HTTP::Response->parse( $easy->head() . $easy->body() );

DESCRIPTION

Net::Curl is wonderful, but Net::Curl::Easy is a bit clunky for day-to-day use. This library attempts to make that, well, “easier”. :-)

This module extends Net::Curl::Easy, with differences as noted here:

DIFFERENCES FROM Net::Curl::Easy

  • The response headers and body go to an internal buffer by default. Net::Curl::Easy simply adopts libcurl’s defaults, which is understandable but frequently unhelpful.

  • Character encoding. As of this writing Net::Curl::Easy uses SvPV to translate Perl strings to C, which means that what libcurl receives depends on how Perl internally stores your string. Thus, the same string given to Net::Curl::Easy can yield different input to libcurl depending on how Perl has decided to store that string.

    This library fixes that by requiring all strings that it receives to be byte strings and normalizing Perl’s internal storage before calling into Net::Curl::Easy.

  • Several methods are wrapped, as described below.

SEE ALSO

METHODS

Besides those inherited from Net::Curl::Easy, this class defines:

$obj = OBJ->set( $NAME1 => $VALUE1, $NAME2 => $VALUE2, .. )

setopt()s multiple values in a single call. Instead of:

    $easy->setopt( Net::Curl::Easy::CURLOPT_URL, 'http://perl.org' );
    $easy->setopt( Net::Curl::Easy::CURLOPT_VERBOSE, 1 );

… you can do:

    $easy->set( url => 'http://perl.org', verbose => 1 );

See curl_easy_setopt(3) for the full set of options you can give here.

Note that, since OBJ is returned, you can chain calls to this with calls to other methods like perform().

You may not need to call this method since new() calls it for you.

$obj = OBJ->push( $NAME1 => \@VALUES1, $NAME2 => \@VALUES2, .. )

Like set(), but for pushopt().

$value = OBJ->get($NAME)

Like set(), but for getinfo(). This, of course, doesn’t return OBJ, so it can’t be chained.

$str = OBJ->head()

Returns OBJ’s internal HTTP response header buffer, as a byte string.

$str = OBJ->body()

Returns the HTTP response body, as a byte string.

WRAPPED METHODS

  • new() takes a list of key/value pairs and passes it to an internal call to set(). The returned object will always be a (newly-created) hash reference.

  • escape() and send() apply the character encoding fix described above.

  • setopt() and pushopt() fix character encoding and return the instance object.

  • perform() returns the instance object.

STATIC FUNCTIONS

For convenience, Net::Curl::Easy::strerror() is aliased in this module.
