ios-token推送说明

---

1、苹果基于token的推送所使用的通信协议为HTTP/2

https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/sending_notification_requests_to_apns

2、验证当前PHP是否支持HTTP2

$ php --ri curl

curl

NTLMWB => Yes
SPNEGO => Yes

3、不支持时如何处理

通过上图，确认是否满足以下条件

• cURL Information >= 7.54.0
• SSL Version >= OpenSSL/1.0.2s

如果不满足，则需升级curl和/或openssl

4、升级后如何验证是否满足上步要求

$ curl -I 

HTTP/2 200

如果返回头中标识的协议为HTTP/2，则表示达到要求，此时也可通过php --ri curl验证是否支持HTTP/2。
