Question

我有一个REST API，应该将JSON的内容保存到MySQL数据库中。但是它将所有内容都插入为null？这很奇怪，因为无论何时从swift SDK发送JSON都可以正常工作。

 public function saveTracking($request, $response, $args) {
        if(!$this->validToken($response)) {
            return $response;
        }
        $data = $request->getParsedBody();
        $tracking_data = json_decode(json_encode($data['tracking']), FALSE);
        $total_records = 0;
          //error_log(print_r($tracking_data, true));

        foreach($tracking_data as $key => $value) {
            $tracking = new EstablishmentTracking();
            $tracking->mobile_user_id = $this->authUser->id;
            $tracking->report_date = $value->report_date;
            $tracking->establishment_id = $value->establishment_id;
            if ($value->platform == MobileUser::ANDROID || $value->platform == MobileUser::IOS) {
                $tracking->platform = $value->platform;
            }
            $tracking->purchase_id = $value->purchase_id;

            error_log(print_r($tracking, true));
            $this->establishmentService->saveEstablishmentTracking($tracking);
            $total_records++;
        }
        $arr = array("status" => "ok"
                    ,"total_records" => $total_records
                    );
        print_r($arr);
        $newResponse = $response->withJson($arr);
        return $newResponse;
    }

添加一行打印变量内容后，我得到以下内容：

stdClass Object
(
    [establishment_id] => 39
    [report_date] => 2018-05-31 18:45:05
    [platform] => android
    [purchase_id] => 0

是不是正确地将JSON作为数组发送？什么似乎是问题？

我假设json对象导致问题是$ tracking_data，你正在使用的json解码需要从false到true的第二个值，这会将它转换为php数组，它可以用键重复stdClass可能不会显示其属性< / p>

将null值插入数据库
