【问题描述】：

我有一个从 PARSE.COM 接收推送通知并且工作正常的 Android 应用程序，现在我想从 PHP 发送通知并且我收到了这条消息... {"code":107,"error":"Invalid JSON: m01011205"}

怎么了，你有什么想法吗？

这是我的 PHP 代码

   <?php

  $APPLICATION_ID = "my application id";
  $REST_API_KEY = "my api key";
  $MESSAGE = "Notificación de Prueba";

if (!empty($_POST)) {

    $errors = array();
    foreach (array('app' => 'APPLICATION_ID', 'api' => 'REST_API_KEY', 'body' => 'MESSAGE') as $key => $var) {
        if (empty($_POST[$key])) {
            $errors[$var] = true;
        } else {
            $$var = $_POST[$key];
        }
    }

    if (!$errors) {
        $url = 'https://api.parse.com/1/push';
        $data = array(
            "channels" => "m01011205",
            "deviceType" => 'android',
            "data" => array(
                "alert" => $MESSAGE,
            ),
        );
        $_data = json_encode($data);
        $headers = array(
            'X-Parse-Application-Id: ' . $APPLICATION_ID,
            'X-Parse-REST-API-Key: ' . $REST_API_KEY,
            'Content-Type: application/json',
            'Content-Length: ' . strlen($_data),
        );

        $curl = curl_init($url);
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $_data);
        curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        $response = curl_exec($curl);
    }
}

【解决方案1】：

我通常使用 Parse 框架来发送推送通知，因为它有一个 SDK 和示例。

https://parse.com/docs/php/guide#push-notifications

例如：

// Find users near a given location
$userQuery = ParseUser::query();
$userQuery->withinMiles("location", $stadiumLocation, 1.0);

// Find devices associated with these users
$pushQuery = ParseInstallation::query();
$pushQuery->matchesQuery('user', $userQuery);

// Send push notification to query

ParsePush::send(array(
  "where" => $pushQuery,
  "data" => array(
    "alert" => "Free hotdogs at the Parse concession stand!"
  )
));
