Question

假设一个非常简单的函数来查询查询自动完成：

$query_google_places = function ($input, array $location = null) {
    $parameters = ['key' => 'AIzaSyAjCY7qYiaMv8Kkk_-D1Ha7wlRkr5neppk', 'input' => $input, 'sensor' => 'false'];

    if ($location) {
        $parameters['location'] = $location['lat'] . ',' . $location['lng'];
        $parameters['radius'] = 10000;
    }

    $url = 'https://maps.googleapis.com/maps/api/place/queryautocomplete/json?' . \http_build_query($parameters);

    $response = file_get_contents($url);

    return $response;
};

返回：

如何获得每个结果的坐标？请注意，这是服务器端问题。

Answer 1

IMO，自动完成或查询自动填充结果与搜索结果存在于不同的世界中。 Google假定您不应该在自动完成列表中需要坐标，因为这不是您将在地图或任何控制器中显示的数据。您将呈现的数据将是真正“搜索”请求的结果。

结论：您应该在nearby search，text search或details等终端上再次呼叫Google服务器以获取坐标。

如果您想使用详细信息，例如，如果用户点击自动填充中的预测，您将使用reference属性作为您的http请求的参数来识别所点击的预测。

如何从查询自动完成中获取坐标？
