json - Laravel - 从 Foursquare API 获取和解析“复杂”JSON 响应

Question

我很难在我的 Laravel 控制器中解析 JSON 响应。它在“简单”响应中运行良好，但是这个有很多嵌套数组，所以我很困惑我应该如何去做。

到目前为止，这是我的控制器中的内容：

    public function foursquare()
{
  $response = Http::get('https://api.foursquare.com/v2/venues/explore', [
    'client_id' => 'XYZXYZ',
    'client_secret' => 'XYZXYZ',
    'limit' => 10,
    'v' => 20210404,
    'near' => 'Paris',
]);
$foursquare = json_decode($response->body());
foreach($venues as $venue){}

虽然我不知道在我的 foreach 循环中放什么。我希望提取所有场地名称，例如在下面的示例中：“Parc des Buttes-Chaumont”和“Grand Bassin du Jardin du Luxembourg”。我该怎么做呢？

这是一个示例响应

Answer 1

然后，您应该循环遍历$response['response']['groups']. 在您的回复中，项目有对象数组，在循环中访问它像这样

$i = 0;
foreach($response['response']['groups'] as $key => $value) 
{
  echo $value['items']['venue']['name'];
}

您可以尝试使用此代码，这可能会给您带来想法。
