有什么方法可以获取 Json 中的维基百科页面数据吗？

Question

我想获取https://en.wikipedia.org/wiki/Cat的完整数据。我尝试了使用 wiki api 的不同方法，但无法获取 Json 中的数据。我只能获取猫的第一个描述。有没有办法获取Json格式的完整页面内容？

Answer 1

使用Api Sandbox，您可以创建一个请求，例如；

http://en.wikipedia.org//w/api.php?action=query&format=json&prop=revisions&titles=Cat&formatversion=2&rvprop=content&rvslots=*

使用format=json检索 Json，使用rvprop=content+rvslots=*获取完整内容。

注意：内容仍为 MediaWiki 格式

结果（修剪后）；

{
    "batchcomplete": true,
    "query": {
        "pages": [
            {
                "pageid": 6678,
                "ns": 0,
                "title": "Cat",
                "revisions": [
                    {
                        "slots": {
                            "main": {
                                "contentmodel": "wikitext",
                                "contentformat": "text/x-wiki",
                                "content": "{{Good article}}\n{{pp-semi-indef|small=yes}}{{pp-move-indef|small=yes}}\n{{short description|Domesticated feline}}\n{{about|the species that is commonly kept as a pet|the cat family|Felidae|other uses|Cat (disambiguation)|and|Cats (disambiguation)}}\n{{technical reasons|Cat #1|the album|Cat 1 (album)}}\n{{Use dmy dates|date=February 2019}}{{Use American English|date=January 2020}}<!-- Per MOS:ENGVAR and MOS:DATEVAR, articles should conform to one overall spelling of English and date format, typically the ones with which it was created when the topic has no strong national ties.

                            }
                        }
                    }
                ]
            }
        ]
    }
}

可选；添加prop=extracts以更改 MediaWiki 格式的输出以获得“已清理”的响应；

../api.php?action=query&format=json&prop=extracts&titles=Cat&formatversion=2&rvprop=content&rvslots=*

                "title": "Cat",
                "extract": "<p class=\"mw-empty-elt\">\n\n</p>\n\n\n\n<p class=\"mw-empty-elt\">\n\n</p>\n<p>The <b>cat</b> (<i>Felis catus</i>) is a small carnivorous mammal.
