Pelagios Widget not working

[Jessica Ogden]

Hi there -

I noticed a while back that our Pelagios widget isn't working any more on Fasti and have finally sat down to take a look. It doesn't seem to be working on the widget demo either at (http://pelagios.github.io/pelagios-widgets/) and getting the same response: "Error: Pleiades not responding We cannot display the name and map at the moment because the Pleiades website is not responding.."

I'm getting a '405 Method not allowed' on the response to the json POST - any ideas?

Thanks in advance for any insight..

Best wishes,

Jess

Hi Jess,

 

hm – I’m seeing the following error message:

 

XMLHttpRequest cannot load http://pleiades.stoa.org/places/579885/json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://pelagios.github.io' is therefore not allowed access.

 

which means cross-origin (CORS) requests are no longer possible on the Pleiades server.

 

@Tom: do you have any time to look into the issue? Seems that the CORS server setting (i.e. the header additional “Access-Control-Allow-Origin” response header,  set to “*”) that used to be there has gone lost :-(

 

Cheers & thanks,

Rainer

All:

I’ll put it on the list (things are a bit stretched at the moment, I’m afraid). It certainly was not removed intentionally (I was unaware it existed); it must have been an inadvertent casualty of my battles against bots that were taking down our site.

Thanks all. No problem Tom - thanks for looking into this!

I think the error message you’re seeing may be masking a different issue. I am seeing Access-Control-Allow-Origin: * in response to a request for the URL you mentioned. Viz:

Can you send me a dump of the full request, with headers, that’s throwing the error on your end? I may be inadvertently blocking you as a bot; we serve a 403 to requests for json resources that we think are coming from search bots and bad actors. We may need to tweak the rules to let pelagios traffic through.

Sorry for the hassle.

Thanks,

Tom

Hi Tom,

Indeed - if I just visit the URL with my browser, I'm getting the JSON just fine, with Access-Control-Allow-Origin:*. So this sounds as if we fall into the bot-blocking rule. The request sent by the Widget sample page is this:

Request URL:http://pleiades.stoa.org/places/579885/json

Request Headers
POST http://pleiades.stoa.org/places/579885/json HTTP/1.1
Accept: application/json, text/javascript, */*; q=0.01
Referer: http://pelagios.github.io/pelagios-widgets/

User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36

Cheers,
Rainer

Ah, can you not use GET? We don’t allow POST against json URIs.

RewriteCond %{REQUEST_METHOD} POST
RewriteRule ^/places/\d+/json$ - [L,R=405]

Ouch - hm. I dug through the code and think I found the bit that makes the request.

@Juliette: are you still on this list? If so, it's probably quickest if you can take a look. (I assume it's this one: https://github.com/pelagios/pelagios-widgets/blob/master/src/app/util.js#L37-41, but may be wrong.) If you don't have time: any hints on what I need to do to build a release after fixing the code? :-)

Cheers,
Rainer

Only just seen this - I'm on maternity leave at the moment with my hands full with a baby and toddler!

Rainer - I'll send you some instructions for building a release when I get the chance.
