最简单iOS服务端apns推送go实现

iOS服务端批量推送

1.官方文档:

https://developer.apple.com/library/archive/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CommunicatingwithAPNs.html#//apple_ref/doc/uid/TP40008194-CH11-SW1

2.踩坑经历,项目为了提高推送效率,之前推送用的socket长链接,不断的向apple的网关写数据,这种情况很糟糕,只有出错的情况,才会有反馈

3.苹果新的解决方法

http2,对http2,关于http2请自己维基百科

4.理解原理

问:批量推送你是采用的http,还是tcp的socket

答:如果你是从0开始的话,建议你直接采用APNs最新的https/2.0协议,支持长连接,而且每次调用都有相应的应答,不要再用以前的tcp socket方式,有很多坑要躺,我是一路躺过来的

问:socket方式,是不是效率更好,更节省时间

答:https/2.0协议具备了tcp和http的特性,效率也不差;而且支持长连接,每个请求APNs还会给你应答;以前的tcp socket协议,只有出错了才会给你应答,巨坑

问:好像是,如果用户卸载了app,就是token失效了,socket就直接出错,断了

答:遇到失效的socket,也不一定会socket直接退出,得看APNs的处理机制;APNs应该是当出错达到一定次数后,直接掐掉socket;很多坑要填,建议你直接用https/2.0,我都打算升级上去了。

问:这个http2,每一个的返回值,能不能确定消息到达端了,方便统计

答:不是到端,而是代表APNs正确接收到你的请求了,至于能否到app端,就得看实际情况了,这个是没有返回,也没有统计的,需要app自己做

5.明白了原理,推送很简单,几行代码:

func main() {

    cert, err := certificate.FromP12File("/Users/yaowan/Downloads/cert.p12", "123456")
    if err != nil {
        log.Fatal("Cert Error:", err)
    }

    notification := &apns2.Notification{}
    notification.DeviceToken = "ea7f974617a338aaa84fee8b7a7d6516794f1103a2771d20133cc01ac0d3cffb"
    notification.Topic = "com.xiyouzhi.danaotianzhu"
    //notification.Payload = []byte(`{"aps":{"alert":"Hello!"}}`) // See Payload section below
    notification.Payload = []byte(`{
    "aps": {
        "category": "category",
        "content-available": 1,
        "alert": {
            "launch-image": "icon.icon",
            "action-loc-key": "LocalizedActionButtonKey",
            "loc-key": "LocalizedAlertMessage",
            "subtitle-loc-key": "LocalizedAlertSubtitle",
            "title-loc-key": "LocalizedAlertTitle"
        },
        "url": "https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1543493128&di=ec8f8beae886e173fdc763a688ce4363&imgtype=jpg&er=1&src=http%3A%2F%2Fwww.znsfagri.com%2Fuploadfile%2Feditor%2Fimage%2F20170626%2F20170626151136_11631.jpg",
        "sound": "sound.wav",
        "badge": 2,
        "mutable-content": 1
    },
    "name": "value",
    "taskId": "9988",
    "url": "https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1543493128&di=ec8f8beae886e173fdc763a688ce4363&imgtype=jpg&er=1&src=http%3A%2F%2Fwww.znsfagri.com%2Fuploadfile%2Feditor%2Fimage%2F20170626%2F20170626151136_11631.jpg"
       

}`) // See Payload section below


    client := apns2.NewClient(cert).Development()
    res, err := client.Push(notification)

    if err != nil {
        log.Fatal("push Error:", err)
    }

    fmt.Printf("%v %v %v\n", res.StatusCode, res.ApnsID, res.Reason)
}
