ApnsPHP - 发送推送通知时出错

Question

我集成了推送通知库来发送推送通知。当我在本地机器上对其进行测试时，它运行良好，但是当我将库示例代码上传到实时服务器时，它抛出了错误，我将响应粘贴在下面...我发现整个响应中的真正错误是 --> 'ERROR ：无法发送消息 ID 1：缺少有效负载 (4)'。我需要帮助来解决这个问题。

PS：google 群里也有人发过同样的问题，但是没有解决办法。

经过一天的测试，我找到了问题所在：json_encode 函数采用 5.3 PHP 版本的第二个参数“options”： http://php.net/manual/en/function.json-encode.php

本地我有 PHP V5.3.x，所以代码在 json_encode 函数中使用第二个参数可以正常工作。但是在实时服务器上，PHP 版本是 5.2.6，因此 json_encode 代码中的第二个参数会导致问题并抛出“Missing Payload”错误。我刚刚删除了第二个参数，它对我来说很好:)
