Need to extract abstract of a wikipedia page
by aditya srinivas 23 Nov '23

23 Nov '23

Hello, I am writing a Java program to extract the abstract of the wikipedia page given the title of the wikipedia page. I have done some research and found out that the abstract with be in rvsection=0 So for example if I want the abstract of 'Eiffel Tower" wiki page then I am querying using the api in the following way. http://en.wikipedia.org/w/api.php?action=query&prop=revisions&titles=Eiffel… and parse the XML data which we get and take the wikitext in the tag <rev xml:space="preserve"> which represents the abstract of the wikipedia page. But this wiki text also contains the infobox data which I do not need. I would like to know if there is anyway in which I can remove the infobox data and get only the wikitext related to the page's abstract Or if there is any alternative method by which I can get the abstract of the page directly. Looking forward to your help. Thanks in Advance Aditya Uppu

A question about UPLOAD update
by Liu Chenheng 02 Dec '14

02 Dec '14

Hi, All, I found in some of the UPLOAD update, there is no page id: <rc type="log" ns="6" title="File:Lucian A. Sperta- Nunez.jpg" rcid=" 114549183" pageid="0" revid="0" old_revid="0" user="Azarel63"oldlen="0" newlen="0" timestamp="2014-01-05T11:09:38Z" comment="User created page with UploadWizard" logid="77242320" logtype="upload"logaction="upload" img_sha1=" sf9t03wg27tl73nnde3jzfuxncefux9" img_timestamp="2014-01-05T11:09:36Z"/> <rc type="log" ns="6" title="File:Gingerbread spices (annotated).jpg" rcid=" 114549185" pageid="30485540" revid="0" old_revid="0"user="SKopp" oldlen="0" newlen="0" timestamp="2014-01-05T11:09:37Z" comment="User created page with UploadWizard" logid="77242318"logtype="upload" logaction="upload" img_sha1=" q84abqjr2n4bmn7o6j4uovpl5ufs2gq" img_timestamp="2014-01-05T11:09:37Z"/> The first one has no page id but the second one has. Does anybody can tell me the differences? Thanks, Ethan Liu

Changes in API action=parse&mobileformat=...
by Max Semenik 09 Jun '14

09 Jun '14

Hi, in response to bug 54607 [1], we've changed the semantics of the mobileformat parameter to action=parse == Summary == Previously, it used to accept strings 'html' or 'wml', later just 'html' and modify the structure of output (see below). This was problematic because you needed to retrieve the HTML from output in different ways, depending on whether mobileformat is specified or not. Now, mobileformat is a boolean parameter, that is if there's a 'mobileformat' parameter in request, it will be treated as "the output should be mobile-friendly", regardless of value. And the output structure will be the same. For compatibility with older callers, mobileformat=(html|wml) will be special-cased to return the older structure at least for 6 month from now. These changes will start being rolled out to the WMF sites starting from tomorrow, Tuesday October 24th and this process will be complete by October 31st. == Examples == === Non-mobile parse === api.php?action=parse&format=xml { "parse": { "title": "...", "text": { "*": "foo" } } } api.php?action=parse&format=json <?xml version="1.0"?> <api> <parse title="..." displaytitle="..."> <text xml:space="preserve">foo</text> </parse> </api> === Parse that outputs mobile HTML, old style === api.php?action=parse&format=json&mobileformat=html { "parse": { "title": "API", "text": "foo" } } api.php?action=parse&format=xml&mobileformat=html <?xml version="1.0"?> <api> <parse title="..." text="foo" displaytitle="..."> </parse> </api> === Parse that outputs mobile HTML, new style === api.php?action=parse&format=...&mobileformat Same as for non-mobile parses. == FAQ == Q: I didn't use mobileformat before, does anything change for me? A: No. Q: I use mobileformat=html, will my bot/tool be broken now? A: No, you will have 6 months to switch to new style. Q: I'm only planning to use mobileformat, what should I do? A: Just use the new style. Q: How did this format discrepancy appear in the first place? A: To err is human. ----- [1] https://bugzilla.wikimedia.org/show_bug.cgi?id=54607 -- Best regards, Max Semenik ([[User:MaxSem]])

Weird response from API when using generator
by Christoffer G. Thomsen 28 Jan '14

28 Jan '14

Hi I am trying to retrieve the categories of new pages via the API on the Danish Wikipedia using this API request: https://da.wikipedia.org/w/api.php?action=query&prop=categories&format=json… When I make that request, I get this response https://gist.github.com/cgtdk/e746b6042883b970c640 (a non-broken up version of the API request URL has been added to the gist as a comment). The interesting part is line 76 to 86. This is the response item for the page "VM i bandy 2015". It claims that this page only has one category, "Kategori:Fremtidige sportsbegivenheder", but it actually has had three categories ever since the first (and only, as of writing this) revision: Kategori:Fremtidige sportsbegivenheder, Kategori:VM i bandy, and Kategori:Sport i 2015. I have tried to do this several times (with minor modifications) both in the API Sandbox on dawiki and directly. When I query the page directly, like this: https://da.wikipedia.org/w/api.php?action=query&prop=categories&format=json… I get this response: https://gist.github.com/cgtdk/69e874cf7d3fae6ee506 which shows the correct category information for the page. What is going on? Am I doing something wrong or is there a bug? Thanks, Christoffer G. Thomsen (meta:User:Cgtdk)

[Mediawiki-api-announce] BREAKING CHANGE: Improved RevDel support
by Brad Jorsch (Anomie) 23 Jan '14

23 Jan '14

Gerrit change 107389[1] adds RevDel support to various API query modules, so for example a user with the 'deletedhistory' right will be able to retrieve the user and summary from prop=revisions. This will cause some changes: - list=deletedrevs, list=filearchive, list=recentchanges, and list=watchlist formerly would not return any information at all for entries where any field was revision-deleted. These entries will now be returned. "hidden" indicators will be provided as is done for modules such as prop=revisions. - prop=imageinfo, list=logevents, prop=revisions, and list=usercontribs will now return field values in addition to the "hidden" indicators, if the user has the necessary user rights. - When "hidden" indicators are returned, a new indicator "suppressed" may also be returned to indicate whether suppression was activated. - prop=imageinfo will now return info for revision-deleted files. - list=logevents, when searching by user or title, will no longer skip revisions where the user or title was revision-deleted if the requesting user has the deletedhistory right. - list=usercontributions will now look at the correct user rights (deletedhistory and suppressrevision, not hideuser) to determine whether to hide revision-deleted contributions. All clients should be updated to expect rows with hidden fields for deletedrevs, filearchive, recentchanges, and watchlist, and clients with advanced permissions should be updated to properly handle (and to not publicly reveal) the data for revision-deleted fields from these modules as well as imageinfo, logevents, revisions, and usercontribs. These changes will be deployed to WMF wikis with 1.23wmf11, see https://www.mediawiki.org/wiki/MediaWiki_1.23/Roadmap for the schedule.

Guidance Needed!!! To call the API from Codecademy to edit wiki pages
by Diwanshi Pandey 21 Jan '14

21 Jan '14

Hello All, I am Diwanshi Pandey, an OPW intern working on the project "Completing mediawiki API development course on Codecademy" . I have completed Parsing and Querying aspects of API but stuck with Modifications as i don't have required permissions. The link to the course: http://www.codecademy.com/courses/web-intermediate-en-BLea4/4/1 I was trying to get an edit token but there was a warning saying: "Unrecognized value for parameter 'intoken': edit" The reason of this issue is certainly because of "callback" parameter. I have also filed a bug as the above warning is unclear. In my course, I want to cover getting a token , editing a page , add a page to watchlist , etc but not deleting a page. I am blocked by this isuue. Does anybody know some other way to code it? or Can someone guide me through some other process? Thanks -- *Regards,* *Diwanshi Pandey*

[Mediawiki-api-announce] Changes to 'assert' handling on WMF wikis
by Brad Jorsch (Anomie) 06 Jan '14

06 Jan '14

The AssertEdit extension has long been installed on WMF wikis, allowing bots to include "&assert=user" or "&assert=bot" in their action=edit requests to prevent accidentally editing while logged out. With Gerrit change 90263,[1] the functionality will be included in MediaWiki core. At the same time, the following changes will be made to the functioning of this feature: * Assertion will be available on all API actions, not just edit. * Assertion failure will now be indicated by an API error, code 'assertbotfailed' or 'assertuserfailed'. * The 'nassert' parameter will be ignored, and using it will give an unrecognized parameter warning. * Other assertions, such as 'true', 'false', and 'exists', will no longer function and attempting to use them will result in an 'unknown_assert' error. Most clients should notice little change from this transition besides the fact of receiving an error rather than a failure status from action=edit. This change will be rolled out with 1.23wmf10, see https://www.mediawiki.org/wiki/MediaWiki_1.23/Roadmap for the schedule.

How to know the API changes
by Liu Chenheng 06 Jan '14

06 Jan '14

Hi, All, I'd like to be notified as soon as the API changes. A simple way is to monitor the page http://en.wikipedia.org/w/api.php Here is my problem: Will the page http://en.wikipedia.org/w/api.php be always updated when the API changes (i.e. add/remove some new params) or the format of the response changes. If not, are there any ways to monitor that? Thanks.
