Question

我正在尝试使用谷歌云消息中的推送通知，我正在传递一个数组om注册ID，但由于某种原因，我得到以下错误：

<?php
function getdb() {
    $db = pg_connect("...") or die('connection failed');
    return $db;
}
?>

这是我试图传递的部分：

Field "data" must be a JSON array: You have just invited to play 'Soccer'

不是gcm的代码是：

"registred_ids":["APA91bF9itasGCSK8NbD9u5GJWnEmbWCdS0sEn_xxRVbVpfI0_3FKkvxVBr5xtdE26VZgOO8rCBpf4CaAzHUbMj7PmmDxqpdbWO6VBrPB8dW4CPqPovJbnB_p1Ha_fuwyf8SnOqgOFajK8HEdiZO65qUljO2wCuuDQ"]

和传递注册ID的代码是：

      <?php


    class GCM {

        function __construct() {

        }
        /**
         * Sending Push Notification
         */
        public function send_notification($registatoin_ids, $message) {
            // include config
            include_once 'connection.php';

            // Set POST variables
            $url = 'https://android.googleapis.com/gcm/send';

            $fields = array(
                'registration_ids' => $registatoin_ids,
                'data' => $message,
            );

            $headers = array(
                'Authorization: key=' .GOOGLE_API_KEY,
                'Content-Type: application/json'
            );
            // Open connection
            $ch = curl_init();

            // Set the url, number of POST vars, POST data
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );
            curl_setopt($ch, CURLOPT_POST, true);
            curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

            // Disabling SSL Certificate support temporarly
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

            curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

            // Execute post
            $result = curl_exec($ch);
            if ($result === FALSE) {
                die('Curl failed: ' . curl_error($ch));
            }

            // Close connection
            curl_close($ch);
            echo $result;
        }
    }
    ?>

Answer 1

使用此 -

$fields = array(
            'registration_ids' => $registatoin_ids,
            'data' => array("message" => $message),
        );

Answer 2

它说数据字段需要是一个数组，但你要将它设置为$ message，这是一个字符串，而不是一个数组。

Answer 3

Field "data" must be a JSON array: You have just invited to play 'Soccer'

这意味着数据节点中传递的值不是json。将$ message编码到json中将修复错误。

将数据转换为JSON数组
