NAME

Net::Twitter::Role::WrapError - Wraps Net::Twitter exceptions

VERSION

version 4.00001

SYNOPSIS

use Net::Twitter;

my $nt = Net::Twitter->new(username => $username, password => $password);

my $followers = $nt->followers;
if ( !followers ) {
    warn $nt->http_message;
}

DESCRIPTION

This module provides an alternate error handling strategy for Net::Twitter. Rather than throwing exceptions, API methods return undef and error information is available through method calls on the Net::Twitter object.

This is the error handling strategy used when trait Legacy is used. It was the error handling strategy employed by Net::Twitter prior to version 3.00.

METHODS

new

This method takes the same parameters as "new" in Net::Twitter.

get_error

Returns undef if there was no error or a HASH ref containing the Twitter error response. Occasionally, a Twitter API call results in an error with no error content returned from Twitter. When that occurs, get_error returns a simulated error HASH ref.

NOTE: Versions of Net::Twitter prior to 3.0 sometimes returned a string rather than a HASH ref, on error. This was a bug. Always expect undef on success and a HASH ref on error.

http_code

Returns the HTTP response code the most recent API method call if it ended in error.

http_message

Returns the HTTP message for the most recent API method call if it ended in error.
