I've been looking for a way to query the wikipedia api based on a search string for a list of articles with the following properties:
- Title
- Snippet/Description
- One or more images related to the article.
I also have to make the query using jsonp.
I've tried using the list=search parameter
But it seems to ignore the prop=images, I've also tried variations using the prop=imageinfo and prop=pageimages. But they all give me the same result as just using the list=search.
I've also tried action=opensearch
http://en.wikipedia.org/w/api.php?action=opensearch&search=test&limit=10&format=xml
Which gives me exactly what I want when i set format=xml, but returns a simple array of page titles when using format=json and therefore fails because of the jsonp requirement.
Is there another approach to doing this? I'd really like to solve this in a single request rather than make the first search request and then a second request for the images using titles=x|y|z
As Bergi suggested, using generators is the way to go here. Specifically what I would do:
list=search
as a generator, to get the list of articlesprop=pageimages
to get a representative image for each articleprop=extracts
to get a description for each articleThe whole query could look like this:
http://en.wikipedia.org/w/api.php?format=json&action=query&generator=search&gsrnamespace=0&gsrsearch=test&gsrlimit=10&prop=pageimages|extracts&pilimit=max&exintro&explaintext&exsentences=1&exlimit=max
If you want to retrieve any properties, you need to specify a list of pages for which you want to get these; e.g. by using the
titles=
,pageids=
, orrevids=
parameters. You didn't send any, so you did not get a result for theprop=images
.If you did use
api.php?action=query&list=search&srsearch=test&prop=images&titles=test
you would have gotten the search results fortest
and the images of theTest
page.You can however also use the collection that the
list
query generates for your property query, using thelist
module as a generator. The query would look likeapi.php?action=query&generator=search&gsrsearch=test&gsrnamespace=0&gsrprop=snippet&prop=images
. Unfortunately, it does not yield the attributes that the list contained, but only used the pageids for a basic property query.Using two queries is probably the way to go. Btw, I'd recommend to use the
pageimages
property, it will likely give you the best results.
