DESCRIPTION

Net::Twitter::Error encapsulates the HTTP::Response and Twitter error HASH (if any) resulting from a failed API call.

METHODS

new

Constructs a Net::Twitter::Error object. It accepts the following parameters:

http_response

An HTTP::Response object, required.

twitter_error

The error returned by Twitter as a HASH ref. Optional, since some API errors do not include a response from Twitter. They may, instead, be the result of network timeouts, proxy errors, or some other problem that prevents an API response.

twitter_error

Get or set the Twitter error HASH.

http_response

Get or set the HTTP::Response object.

code

Returns the HTTP response code.

message

Returns the HTTP response message.

has_twitter_error

Returns true if the object contains a Twitter error HASH.

error

Returns the error value from the twitter_error HASH ref if there is one. Otherwise, it returns the string "[unknown]". Includes a stack trace.

twitter_error_text

Returns the error value from the twitter_error HASH ref if there is one. Otherwise, returns an empty string

twitter_error_code

Returns the first numeric twitter error code from the JSON response body, if there is one. Otherwise, it returns 0 so the result should always be safe use in a numeric test.

See Twitter Error Codes for a list of defined error codes.

stack_trace

Returns a Devel::StackTrace object.

stack_frame($i)

Returns the $ith stack frame as a Devel::StackTrace::Frame object.
