Guzzle ~6 和 Google Place API - 使用分页时出错（pagetoken）

Question

我正在尝试在几个地点 (lat/lng) 附近获得一组 universities。

为此，我将 Google Maps Places API Web Services 和 PHP 中的这个小脚本与 Guzzle ~6.0.

一起使用

我正在使用此代码获取 Google API：

$positions = [
    [51.388667, 2.557513], // <- no next_page_token
    [51.388667, 2.750000], // <- next_page_token
];

foreach($geo in $positions) {
    getJsonPlacesResponse($geo);
}

function getJsonPlacesResponse($geo)
{
    $lat = $geo[0];
    $lng = $geo[1];
    if ($lat == 'Latitude') return;
    $r1 = 'https://maps.googleapis.com/maps/api/place/nearbysearch/json?key='.getenv('GMAPS_API_KEY').'&radius=50000'.'&type=university'.'&location='.$lat.','.$lng;

    return getAndParse($r1);
}


function getAndParse($url)
{
    $client = new GuzzleHttp\Client();
    $body = $client->get($url, ['debug' => true])->getBody();

    $obj = json_decode($body, true);
    if ($obj['status'] !== 'OK') {
        return [];
    }

    if (isset($obj['next_page_token'])) {
        echo "--Get additionals results\n";
        return array_merge($obj['results'], getAndParse($url."&pagetoken=".$obj['next_page_token']));
    } else {
        return $obj['results'];
    }
}

此脚本工作正常，除非响应包含 "next_page_token"，在这种情况下 api return a HTTP/1.1 200 OK:

{
   "html_attributions" : [],
   "results" : [],
   "status" : "INVALID_REQUEST"
}

通过启用 debug mode 我可以在控制台中看到 url：

}

但是当我测试 url /maps/api/place/nearbysearch/json?key=AIza...31E directly in Google Chrome, and it's just works fine: Screenshot of the Google Chrome Dev Tools.

而且我不知道问题出在哪里！

我在考虑一些 url 编码问题，但我读到 guzzle 已经对 url 进行了编码，所以是的，我不知道。

注意：我已经限制了密钥访问（基于 IP），所以它不应该为你使用这个特定的密钥。

感谢您的帮助。
