It should also be suitable for one-liners. If you need more control or access to the header fields in the requests sent and responses received, then you should use the full object-oriented interface provided by the C module. The following functions are provided (and exported) by this module: =over 3 =item get($url) The get() function will fetch the document identified by the given URL and return it. It returns C if it fails. The $url argument can be either a string or a reference to a URI object. You will not be able to examine the response code or response headers (like 'Content-Type') when you are accessing the web using this function. If you need that information you should use the full OO interface (see L). =item head($url) Get document headers. Returns the following 5 values if successful: ($content_type, $document_length, $modified_time, $expires, $server) Returns an empty list if it fails. In scalar context returns TRUE if successful. =item getprint($url) Get and print a document identified by a URL. The document is printed to the selected default filehandle for output (normally STDOUT) as data is received from the network. If the request fails, then the status code and message are printed on STDERR. The return value is the HTTP response code. =item getstore($url, $file) Gets a document identified by a URL and stores it in the file. The return value is the HTTP response code. =item mirror($url, $file) Get and store a document identified by a URL, using I, and checking the I. Returns the HTTP response code. =back This module also exports the HTTP::Status constants and procedures. You can use them when you check the response code from getprint(), getstore() or mirror(). The constants are: RC_CONTINUE RC_SWITCHING_PROTOCOLS RC_OK RC_CREATED RC_ACCEPTED RC_NON_AUTHORITATIVE_INFORMATION RC_NO_CONTENT RC_RESET_CONTENT RC_PARTIAL_CONTENT RC_MULTIPLE_CHOICES RC_MOVED_PERMANENTLY RC_MOVED_TEMPORARILY RC_SEE_OTHER RC_NOT_MODIFIED RC_USE_PROXY RC_BAD_REQUEST RC_UNAUTHORIZED RC_PAYMENT_REQUIRED RC_FORBIDDEN RC_NOT_FOUND RC_METHOD_NOT_ALLOWED RC_NOT_ACCEPTABLE RC_PROXY_AUTHENTICATION_REQUIRED RC_REQUEST_TIMEOUT RC_CONFLICT RC_GONE RC_LENGTH_REQUIRED RC_PRECONDITION_FAILED RC_REQUEST_ENTITY_TOO_LARGE RC_REQUEST_URI_TOO_LARGE RC_UNSUPPORTED_MEDIA_TYPE RC_INTERNAL_SERVER_ERROR RC_NOT_IMPLEMENTED RC_BAD_GATEWAY RC_SERVICE_UNAVAILABLE RC_GATEWAY_TIMEOUT RC_HTTP_VERSION_NOT_SUPPORTED The HTTP::Status classification functions are: =over 3 =item is_success($rc) True if response code indicated a successful request. =item is_error($rc) True if response code indicated that an error occurred. =back The module will also export the LWP::UserAgent object as C<$ua> if you ask for it explicitly. The user agent created by this module will identify itself as "LWP::Simple/#.##" and will initialize its proxy defaults from the environment (by calling $ua->env_proxy). =head1 CAVEAT Note that if you are using both LWP::Simple and the very popular CGI.pm module, you may be importing a C function from each module, producing a warning like "Prototype mismatch: sub main::head ($) vs none". Get around this problem by just not importing LWP::Simple's C function, like so: use LWP::Simple qw(!head); use CGI qw(:standard); # then only CGI.pm defines a head() Then if you do need LWP::Simple's C function, you can just call it as C. =head1 SEE ALSO L, L, L, L, L, L usr/share/perl5/vendor_perl/Log/Message/Simple.pm000064400000017017147635413730015744 0ustar00package Log::Message::Simple; use if $] > 5.017, 'deprecate'; use strict; use Log::Message private => 0;; BEGIN { use vars qw[$VERSION]; $VERSION = '0.10'; } =pod =head1 NAME Log::Message::Simple - Simplified interface to Log::Message =head1 SYNOPSIS use Log::Message::Simple qw[msg error debug carp croak cluck confess]; use Log::Message::Simple qw[:STD :CARP]; ### standard reporting functionality msg( "Connecting to database", $verbose ); error( "Database connection failed: $@", $verbose ); debug( "Connection arguments were: $args", $debug ); ### standard carp functionality carp( "Wrong arguments passed: @_" ); croak( "Fatal: wrong arguments passed: @_" ); cluck( "Wrong arguments passed -- including stacktrace: @_" ); confess("Fatal: wrong arguments passed -- including stacktrace: @_" ); ### retrieve individual message my @stack = Log::Message::Simple->stack; my @stack = Log::Message::Simple->flush; ### retrieve the entire stack in printable form my $msgs = Log::Message::Simple->stack_as_string; my $trace = Log::Message::Simple->stack_as_string(1); ### redirect output local $Log::Message::Simple::MSG_FH = \*STDERR; local $Log::Message::Simple::ERROR_FH = \*STDERR; local $Log::Message::Simple::DEBUG_FH = \*STDERR; ### force a stacktrace on error local $Log::Message::Simple::STACKTRACE_ON_ERROR = 1 =head1 DESCRIPTION This module provides standardized logging facilities using the C module. =head1 FUNCTIONS =head2 msg("message string" [,VERBOSE]) Records a message on the stack, and prints it to C (or actually C<$MSG_FH>, see the C section below), if the C option is true.
