use WebService::GData::Error;

#create an error object that you can throw by dying...
my $error = new WebService::GData::Error(401,'Unauthorized');

foreach my $error (@{$error->errors}){
    print $error->code;
    print $error->internalreason;

DESCRIPTION

inherits from WebService::GData.

This package can parse error response from Google APIs service. You can also create your own basic error.

All WebService::GData::* classes die a WebService::GData::Error object when something goes wrong.

You should use an eval {}; block to catch the error.

Example:

use WebService::GData::Base;


my $base = new WebService::GData::Base();
eval {
    $base->get($url);
};
#$error is a WebService::GData::Error;
if(my $error=$@){
    #error->code,$error->content, $error->errors
}

CONSTRUCTOR

new

Create a WebService::GData::Error instance.

Parameters:

code:*

This could be an http status or a short string error_code.

content:Scalar

The string can be a Google xml error response, in which case,

it will parse the contents that you can access via the errors() method of the instance.

Return:

WebService::GData::Error

Example:

use WebService::GData::Error;

#create an error object that you can throw by dying...
my $error = new WebService::GData::Error(401,'Unauthorized');

GET METHODS

code

Get back the error code.

Return:

code:Scalar

content

Get back the raw content of the error.

When getting an error from querying one of Google data services, you will get a raw xml response containing possible errors.

In such case,you should loop through the result by using the errors() instance which send back WebService::GData::Error::Entry.

Return:

content:Scalar

errors

Get back a reference array filled with WebService::GData::Error::Entry.

When getting an error from querying one of Google data services, you will get an xml response containing possible errors.

In such case,you should loop through the result of errors().

Errors always send back a reference array (even if there is no error).

Return:

WebService::GData::Error::Entry

Example:

my @errors = $error->errors;#send back WebService::GData::Error::Entry objects

foreach my $error (@{$error->errors}){
    print $error->code;
    print $error->internalreason;
    print $error->domain;
    print $error->location->{type};#this is just a hash
    print $error->location->{content};#this is just a hash
}
