Oh wise and splendiferous monks of the Perly persuasion
I am trying to use REST::Client to update a wiki from some text files. Although I can connect and read data, when I try to POST a page edit, it complains I have not sent a 'token'. The token is meant to go in the headers, the API docco https://www.mediawiki.org/wiki/API:Edit shows it as part of the URL such as
/mediawiki/api.php?action=edit&title=Tst&summary=Tsummary&text=article
+%20content&token=81750dcca64dc
Note:Token above cut short to stop line wrapping on my laptop screen
Now I have added the token in my URI such as above, and got the error:
The 'token' parameter was found in the query string, but must be in th
+e POST body
I have tried adding the token as a custom header in the code: $client->addHeader('token', $token); then I get this error:
The token parameter must be set
Here is my code with an attempt to add token as a custom header
use strict;
use warnings;
use v5.10.0;
use Data::Dumper;
use MIME::Base64;
use JSON;
use REST::Client;
use Getopt::Long;
my $debug = 0;
GetOptions ("debug" => \$debug) or die "Error in command line argumen
+ts\n";
my $wiki = 'http://HeartOfGold.improbable.tea';
my $api = '/mediawiki/api.php';
my $request;
my $JSON = JSON->new->allow_nonref;
# Create rest client and set some options
my $client = REST::Client->new();
$client->setHost($wiki);
$client->addHeader('format', 'json');
# First we get a login token
$request = 'action=login&lgname=Marvin&lgpassword=leftdiode';
my $result = post($request);
my $token = $result->{login}{token};
print "Got Token: $token\n";
$client->addHeader('token', $token);
$request = "action=edit&title=LookupAutomationTest&summary=test%20summ
+ary&text=article%20content";
$result = post($request);
sub post {
my $query = shift @_;
$query .= '&format=json';
my $req = "$api?$query";
print "Fetching data with: POST $req\n" if $debug;
print Dumper $client;
$client->POST($req);
if ( $client->responseCode() == 200 ) {
print "Got Data OK, decoding ... " if $debug;
my $data = $JSON->decode( $client->responseContent() );
print Dumper $data;
return $data;
}
else {
print "Failed with code $client->responseCode()\n";
print Dumper $client->responseContent();
}
}
The first call to log in and get the token works fine.
The second call to edit the page gives the missing token type errors.
As you see the code dumps the client just before posting, so here is the output. One can see the headers are added in the _headers key of the client object but Wiki is ignoring them. I had a similar problem with Service Now a short time back, but I just &stuffed=them in the URI and it was happy then.
