=head1 NAME |
26 |
|
27 |
C4::URL::Checker - base object for checking URL stored in Koha DB |
28 |
|
29 |
=head1 SYNOPSIS |
30 |
|
31 |
use C4::URL::Checker; |
32 |
|
33 |
my $checker = C4::URL::Checker->new( ); |
34 |
$checker->{ host_default } = 'http://mylib.kohalibrary.com'; |
35 |
my $checked_urls = $checker->check_biblio( 123 ); |
36 |
foreach my $url ( @$checked_urls ) { |
37 |
print "url: ", $url->{ url }, "\n", |
38 |
"is_success: ", $url->{ is_success }, "\n", |
39 |
"status: ", $url->{ status }, "\n"; |
40 |
} |
41 |
|
42 |
=head1 FUNCTIONS |
43 |
|
44 |
=head2 new |
45 |
|
46 |
Create a URL Checker. The returned object can be used to set |
47 |
default host variable : |
48 |
|
49 |
my $checker = C4::URL::Checker->new( ); |
50 |
$checker->{ host_default } = 'http://mylib.kohalibrary.com'; |
51 |
|
52 |
=head2 check_biblio |
53 |
|
54 |
Check all URL from a biblio record. Returns a pointer to an array |
55 |
containing all URLs with checking for each of them. |
56 |
|
57 |
my $checked_urls = $checker->check_biblio( 123 ); |
58 |
|
59 |
With 2 URLs, the returned array will look like that: |
60 |
|
61 |
[ |
62 |
{ |
63 |
'url' => 'http://mylib.tamil.fr/img/62265_0055B.JPG', |
64 |
'is_success' => 1, |
65 |
'status' => 'ok' |
66 |
}, |
67 |
{ |
68 |
'url' => 'http://mylib.tamil.fr//img/62265_0055C.JPG', |
69 |
'is_success' => 0, |

'status' => '404 - Page not found' |

=over |
250 |
|
251 |
=item check-url.pl [--verbose|--help] [--agent=agent-string] [--host=http://default.tld] |
252 |
|
253 |
Scan all URLs found in 856$u of bib records |
254 |
and display if resources are available or not. |
255 |
This script is deprecated. You should rather use check-url-quick.pl. |

=head1 PARAMETERS |
260 |
|
261 |
=over |
262 |
|
263 |
=item B<--host=http://default.tld> |
264 |
|
265 |
Server host used when URL doesn't have one, ie doesn't begin with 'http:'. |
266 |
For example, if --host=http://www.mylib.com, then when 856$u contains |
267 |
'img/image.jpg', the url checked is: http://www.mylib.com/image.jpg'. |
268 |
|
269 |
=item B<--verbose|-v> |
270 |
|
271 |
Outputs both successful and failed URLs. |
272 |
|
273 |
=item B<--html> |
274 |
|
275 |
Formats output in HTML. The result can be redirected to a file |
276 |
accessible by http. This way, it's possible to link directly to biblio |
277 |
record in edit mode. With this parameter B<--host-pro> is required. |
278 |
|
279 |
=item B<--host-pro=http://koha-pro.tld> |
280 |
|
281 |
Server host used to link to biblio record editing page. |
282 |
|
283 |
=item B<--agent=agent-string> |
284 |
|
285 |
Change default libwww user-agent string to custom. Some sites do |
286 |
not like libwww user-agent and return false 40x failure codes, |
287 |
so this allows Koha to report itself as Koha, or a browser. |
288 |
|
289 |
=item B<--timeout=15> |
290 |
|
291 |
Timeout for fetching URLs. By default 15 seconds. |
292 |
|
293 |
=item B<--help|-h> |
294 |
|
295 |
Print this help page. |
