背景
想要给iOS用户推送一些信息，又不想使用极光啊，友盟之类的第三方推送SDK，毕竟是只针对iOS用户的，并且用户量不大，于是想到了自己建立推送服务器的想法。其实推送到iOS设备，大部分工作苹果已经为你做好了，所以我要做的工作比较少，有以下几点：
- 推送到哪些设备?
- 这是需要从用户的手机中收集的，当用户选择安装应用并打开它的推送功能时，我们记录下一个从苹果服务器上返回的数据，叫做DeviceToken
- 推送什么内容?
- 内容及部分及各式参见推送文档
- 什么时候推送?
- 在服务器设定相应的推送条件
推送到哪些设备
获取DeviceToken以及相关推送的细节详见喵神博客的活久见的重构 - iOS 10 UserNotifications 框架解析
推送什么内容
使用Node.js推送
使用的是node-apn
推送的效果
"use strict";
const apn = require('apn');
let options = {
token: {
key: "p8证书",
// Replace keyID and teamID with the values you've previously saved.
keyId: "",
teamId: ""
},
production: false
};
let apnProvider = new apn.Provider(options);
// Replace deviceToken with your particular token:
let deviceToken = "deviceToken";
// Prepare the notifications
let notification = new apn.Notification();
notification.expiry = Math.floor(Date.now() / 1000) + 24 * 3600; // will expire in 24 hours from now
notification.badge = 1;
notification.sound = "ping.aiff";
// extra json dict
notification.payload = {"name":"xxx","img":"http://xxxx.jpg"};
// category name
notification.category = "saySomething"
notification.mutableContent = 1
notification.body = "this is content";
notification.title = "this is title"
notification.subtitle= "this is a subtitle"
// Replace this with your app bundle ID:
notification.topic = "bundleID";
// Send the actual notification
apnProvider.send(notification, deviceToken).then( result => {
// Show the result of the send operation:
console.log(result);
});
// Close the server
apnProvider.shutdown();
使用Python推送
使用的是改写过支持iOS10推送新特性的PyAPNs，其中证书的导出参见自己动手搭建苹果推送Push服务器，这里有个小坑就是，运行的时候因为导出的private.pem是有密码的所以你要用一条命令将其的密码取消掉。
import time
from apns import APNs, Frame, Payload, PayloadAlert
apns = APNs(use_sandbox=True, cert_file='public.pem', key_file='private.pem')
# Send a notification
token_hex = 'devecetoken'
# payload = Payload(alert="Hello World!", sound="default", badge=1)
alert = PayloadAlert(title = 'title',subtitle = 'subtitle',body ='this is content')
payload = Payload(alert=alert, sound="default", badge=1, category = 'saySomething',custom={"name":"xxx","img":"http://xxx.jpg"}, mutable_content=True)
# payload.mutable_content = True
apns.gateway_server.send_notification(token_hex, payload)
