如何将Phonegap应用程序与php rest api连接

我在后端使用php（slim php微框架）创建了REST api。所以代码是：索引

$app->post('/coords', 'authenticate', function() use ($app) {
            $response = array();
            //$jsonData = $app->request->post('podaci');
            $jsonData = @file_get_contents('php://input');
$aData = json_decode($jsonData);
$latitude = $aData->location->latitude;
$longitude = $aData->location->longitude;
$podaci = $latitude.' ddd '.$longitude;
            global $user_id;
            $db = new DbHandler();
            // creating new task
            $coords_id = $db->createCoords($user_id, $podaci);
            if ($coords_id != NULL) {
                $response["error"] = false;
                $response["message"] = "Coords insert successfully";
                echoRespnse(201, $response);
            } else {
                $response["error"] = true;
                $response["message"] = "Coords not inserted";
                echoRespnse(200, $response);
            }            
        });

我还有DBhandler文件，代码（函数创建坐标）：

public function createCoords($user_id, $podaci) {
        $stmt = $this->conn->prepare("INSERT INTO coords(podaci) VALUES(?)");
        $stmt->bind_param("s", $podaci);
        $result = $stmt->execute();
        $stmt->close();
    }

我尝试使用带有ajax请求的示例数据进行此REST api，并且工作良好，但是现在我需要将数据从phonegap应用程序发布到服务器，然后我写道：

// BackgroundGeoLocation is highly configurable.
        bgGeo.configure(callbackFn, failureFn, {
            url: 'http://agroagro.com/agroMobile/v1/coords', // <-- Android ONLY:  your server url to send locations to
            params: {
                Auth: 'df6017abde2d2re560896b63a0ee1039',    //  <-- Android ONLY:  HTTP POST params sent to your server when persisting locations.
                foo: 'bar'                              //  <-- Android ONLY:  HTTP POST params sent to your server when persisting locations.
            },
            desiredAccuracy: 0,
            stationaryRadius: 50,
            distanceFilter: 50,
            notificationTitle: 'Background tracking', // <-- android only, customize the title of the notification
            notificationText: 'ENABLED', // <-- android only, customize the text of the notification
            activityType: 'AutomotiveNavigation',
            debug: true, // <-- enable this hear sounds for background-geolocation life-cycle.
            stopOnTerminate: false // <-- enable this to clear background location settings when the app terminates
        });

我在这里阅读了如何制作 php 文件以获取输入数据：https://github.com/christocracy/cordova-plugin-background-geolocation/issues/79

正如你从我的索引中看到的.php代码我写得很好，但有什么问题？当我在安卓手机上进行测试时，这不起作用。
