WebService::GData::Error - create an error and parse errors from Google data APIs v2.
use WebService::GData::Error; #create an error object that you can throw by dying... my $error = new WebService::GData::Error(401,'Unauthorized'); # $error->code; # $error->content; #create an error object in response to a Google Service. my $error = new WebService::GData::Error(401,$responseFromAService); print $error->code; print $error->content;#raw xml content 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 }
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 }
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:
use WebService::GData::Error; #create an error object that you can throw by dying... my $error = new WebService::GData::Error(401,'Unauthorized');
Get back the error code.
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.
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).
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 }
none
