Question

我收到如下 API 回复。我这样做是为了消除响应。并得到以下回应。 $data = json_decode($response);

{#240 ▼
  +"batchcomplete": ""
  +"query": {#243 ▼
    +"pages": {#234 ▼
      +"171166": {#245 ▼

    }
  }
}

我想提取 title 和 content。我该怎么做？

编辑：我已经尝试$data = json_decode($response, true);并通过var_dump($data['query']['pages'])得到以下结果。结果：

array:1 [▼
  171166 => array:4 [▼
    "pageid" => 171166
    "ns" => 0
    "title" => "Nepal"
    "extract" => """

Answer 1

只需将页面用作数组：

$response = json_decode(file_get_contents('https://en.wikipedia.org/w/api.php?action=query&prop=extracts&format=json&exintro=&titles=Stack%20Overflow'));

$pages = (array) $response ->query->pages;
foreach ($pages as $id => $page) {
  echo $page->title;
}

Answer 2

使用formatversion=2以更易于处理的格式获取数据。

$response = json_decode(file_get_contents('https://en.wikipedia.org/w/api.php?action=query&prop=extracts&format=json&formatversion=2&exintro=&titles=Stack%20Overflow'), true);
echo($response['query']['pages'][0]['title']);
