Question

我想使用query操作搜索Wikipedia。我正在使用这个网址：

http://en.wikipedia.org/w/api.php?action=query&format=json&list=search&srsearch=apple

这有效，但我想进入搜索的第一个结果。我怎么能这样做？

注意：当只有一个结果时，该URL工作正常。我只需要标题和一些简短的描述。

Answer 1

我认为你不能在一个查询中同时做到这两件事。

1。要获得第一个结果，请使用Opensearch API。

https://en.wikipedia.org/w/api.php?action=opensearch&search=zyz&limit=1&namespace=0&format=jsonfm

https://en.wikipedia.org/w/api.php
?action=opensearch
&search=zyz          # search query
&limit=1             # return only the first result
&namespace=0         # search only articles, ignoring Talk, Mediawiki, etc.
&format=json         # jsonfm prints the JSON in HTML for debugging.

这将返回：

[
    "Zyz",
    [
        "Zyzomys"
    ],
    [
        ""
    ],
    [
        "https://en.wikipedia.org/wiki/Zyzomys"
    ]
]

2。您现在拥有第一个搜索结果的文章名称。要获得文章的第一个段落（或描述，如你所说），请在此处查看我的答案：https://stackoverflow.com/a/19781754/908703

这是我的解决方案：

Answer 3

实际上维基百科json api只能使用正确的查询，因此我建议使用维基百科搜索并抓取实际文章并使用BeautifulSoup解析它

https://en.wikipedia.org/w/index.php?search=QUERY&title=Special:Search&fulltext=Search

还有模块调用维基百科为你做这个
