[OWSLib-users] csw getrecords2 : request rejected

Thu Aug 2 01:26:03 PDT 2018

Julie,

It just breaks a proxy rule; it just probably means that whoever set up the CSW server didn't tell the proxy administrator to allow some requests through.  So probably you just need to contact the service provider, and tell them what requests you were trying, and get them to change the rule, after all the service GetCaps response does have `<ows:AccessConstraints>Pas de contraintes d'accès</ows:AccessConstraints>`

It could be your user agent isn't allowed, it could be the size of the request, it could be a word in the URL...

If you want an alternative way of gathering all the records, and as the server exposes a sitemap of all records ~
http://www.data.eaufrance.fr/geosource/srv/fre/portal.sitemap then you could just loop though the records, construct the URL you want if different from the listed URL for example from something like http://www.data.eaufrance.fr:/geosource/?uuid=2e703ba0-08eb-4029-a9b1-a6f7f3667b62 (in the sitemap) to something like http://www.data.eaufrance.fr/geosource/srv/fre/xml.metadata.get?uuid=2e703ba0-08eb-4029-a9b1-a6f7f3667b62 (for the full ISO record).

That's something I've done before, but it didn't use OWSLib.

James

Thanks for your answer James. It is indeed a French government website.
I understand the request by blocked, but would you know why ? Could I bypass this somehow ?

Thanks

Julie.
