Question

Hi,

I have a problem with include of web page. For example, after as I wrote

%INCLUDE{"http://localhost:80/index.html"}%

I got an error on the web browser

TWiki detected an internal error - please check your TWiki logs and webserver logs for more information.  Can't locate object method "new" via package "TWiki::Net::HTTPResponse" 

Here is log from twiki

Answer

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

Hmm, that looks like a bug. May be related to CPAN:LWP not being installed on yoru system. Could you check if LWP is installed, and if not, install it?

See also HowToInstallCpanModules

In fact the CPAN:LWP not being installed on my OS. I have installed the CPAN:LWP and a problem disappear. Thanks for suggestion

Now I have the problem with permissions

 Failed to include URL http://localhost/ Can't connect to localhost:80 (Permission denied) 

-- JacekBednarczuk - 31 Dec 2008

Can you include other pages, such as www.google.com?

-- PeterThoeny - 31 Dec 2008

I filed TWikibug:Item6159 for the issue if LWP is not installed.

-- PeterThoeny - 31 Dec 2008

It does not matter what is the page (internal if external) a result is the same how above I look for a reason in the configuration of the Apache, Twiki but without effects Permissions for the internal page http://localhost/index.html are set up 755

In the configuration of the Twiki an allowURLs is set up correctly

$TWiki::cfg{INCLUDE}{AllowURLs} = 1;

I can send a http request from a lwp command and get a response

bash-3.2$ lwp-request http://localhost
<HTML>
<HEAD>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-2">
</HEAD>
<BODY>
<center>Example an easy page</center>
</BODY>
</HTML> 
bash-3.2$ 

I am not able to solve this problem so far

I dont know where maybe the problem. I wrote a easy plugin which gets any www page by using LWP. I have a strange situation because when use this plugin from the Twiki it appears an error 500 Can't connect to localhost:80 (Permission denied). In case of calls it from line command as a perl script the error disappear. Below is a basic code of the plugin

sub _GETURL {
    my($session, $params, $theTopic, $theWeb) = @_;
    my $response = CheckGetUrl($params->{_DEFAULT});
    return "$response";
}

sub CheckGetUrl {
        my($url) = @_;
        my $ua = LWP::UserAgent->new();
        my $request = HTTP::Request->new('GET', $url);
        my $response = $ua->request($request);
        my $answer = $response->content();
        return "$answer";
}

When I call the CheckGetUrl function of new Plugin from the perl script then get the corectly result

#!/usr/bin/perl -w 
use strict;
push(@INC, "/var/www/twiki/lib/");

require TWiki;
require TWiki::Plugins::GetUrlPlugin;
use LWP::UserAgent;
my $response = TWiki::Plugins::GetUrlPlugin::CheckGetUrl("http://localhost");
print "$response";
exit;

Peter,

I have checked this functionality (include website) on another OS with the same version of TWiki and It works properly so it is not the problem of TWiki only my OS. I am changing a status to Answered Questions
