关于osx提取推送通知包失败

Question

我使用https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/NotificationProgrammingGuideForWebsites/PushNotifications/PushNotifications.html#//apple_ref/doc/uid/TP40013225-CH3-SW22

createPushPackage.php

获取pushpackage.zip 但总是收到错误消息

[2016/11/16 11:35:04] {＆＃34; logs＆＃34;：[＆＃34;提取推送通知包失败＆＃34;]}

我做错了什么步骤？
