【IM-02】apns服务的实现

前沿

市面上的推送有很多:极光推送,个推,这是我用过的两款产品,在推送领域都有特点,现在自己开发了一款推送产品MagotanPush,服务端用Node.js语言,移动端用OC,目前是一个初品,也可以商用哈。

1.推送实现流程

说明:

第一步:App注册通知,获得DeviceToken,上报apns服务
第二步:App注册通知,获取到DeviceToken,上报自己服务器,作为用户标识
第三步:配置证书和推送文本,根据DeviceToken进行推送
第四步:APNS服务收到消息,完成特定用户的推送

2.证书配置

2.1.证书配置

网上一大堆,这个我不提供,我相信各位大佬的水平

2.2.pem文件生成

1.打开钥匙串,选择需要生成的推送证书;

2.分别将certificate和private key导出得到对应的.p12文件,证书->apns-dev-cert.p12,秘钥->apns-dev-key.p12;

3.将apns-dev-cert.p12和apns-dev-key.p12文件对应转化为apns-dev-cer.pem和apns-dev-key.pem文件;

openssl pkcs12 -clcerts -nokeys -out apns-dev-cert.pem -in apns-dev-cert.p12
openssl pkcs12 -nocerts -out apns-dev-key.pem -in apns-dev-key.p12

4.将apns-dev-cert.pem和apns-dev-key.pem文件合成为apns-dev.pem文件

cat apns-dev-cert.pem apns-dev-key.pem > apns-dev.pem

5.测试证书有效性

openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert apns-dev-cert.pem -key apns-dev-key.pem

6.终端最后显示以下内容,表示配置pem文件成功

3 iOS端配置

3.1.项目代码编写

#import 
3.1.1.注册推送/获取deviceToken
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    //注册推送
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    // 必须写代理,不然无法监听通知的接收与点击
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionBadge | UNAuthorizationOptionSound) completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if (granted) {
            // 点击允许
            NSLog(@"注册成功");
            [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
                NSLog(@"%@", settings);
            }];
        } else {
            // 点击不允许
            NSLog(@"注册失败");
        }
    }];
    //获取deviceToken
    [application registerForRemoteNotifications];
    return YES;
}
3.1.2. iOS 10收到通知
// iOS 10收到通知
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
    
    NSDictionary * userInfo = notification.request.content.userInfo;
    UNNotificationRequest *request = notification.request; // 收到推送的请求
    UNNotificationContent *content = request.content; // 收到推送的消息内容
    NSNumber *badge = content.badge;  // 推送消息的角标
    NSString *body = content.body;    // 推送消息体
    UNNotificationSound *sound = content.sound;  // 推送消息的声音
    NSString *subtitle = content.subtitle;  // 推送消息的副标题
    NSString *title = content.title;  // 推送消息的标题
    
    if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        NSLog(@"iOS10 前台收到远程通知:%@", userInfo);
    }else {
        // 判断为本地通知
        NSLog(@"iOS10 前台收到本地通知:{\\\\nbody:%@,\\\\ntitle:%@,\\\\nsubtitle:%@,\\\\nbadge:%@,\\\\nsound:%@,\\\\nuserInfo:%@\\\\n}",body,title,subtitle,badge,sound,userInfo);
    }
   completionHandler(UNNotificationPresentationOptionBadge|UNNotificationPresentationOptionSound|UNNotificationPresentationOptionAlert); // 需要执行这个方法,选择是否提醒用户,有Badge、Sound、Alert三种类型可以设置,Alert可以设定前台展示通知栏。
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
    //处理推送过来的数据
    NSLog(@"%@",response.notification.request.content.userInfo);
    completionHandler();
}
3.1.3.将得到的deviceToken传给SDK
// 将得到的deviceToken传给SDK
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
    
    NSString *deviceTokenStr = [[[[deviceToken description] stringByReplacingOccurrencesOfString:@"<" withString:@""] stringByReplacingOccurrencesOfString:@">" withString:@""] stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSLog(@"deviceTokenStr:\n%@",deviceTokenStr);
    [[NSUserDefaults standardUserDefaults] setValue:deviceTokenStr forKey:@"DEVICETOKEN"];
}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(nonnull NSError *)error{
    
    NSLog(@"注册推送失败Error:%@",error.localizedDescription);
}

4.服务端集成

"use strict";

const apn = require("apn");

// deviceToken 数组
let tokens = ["7f56110923c266397a3aa434ce15d3172b5666b98f49543cd78fc45e682f55b4"];

let service = new apn.Provider({
  cert: "apns-dev-cert.pem",
  key: "apns-dev-key.pem",
  gateway: "gateway.sandbox.push.apple.com",
  // gateway: "gateway.push.apple.com"; //线上地址
  // port: 2195, //端口
  passphrase: "关注公众号,找我要密码,hahah" //pem证书密码
});

let note = new apn.Notification();

note.payload = {
  from : "MagotanPush_APNS",
  source : "ios",
  module : "home"
};

note.body = "Hello MagotanPush!";

// 主题 一般取应用标识符(bundle identifier)
note.topic = "geekschen.APNsTest"

console.log(`Sending: ${note.compile()} to ${tokens}`);
service.send(note, tokens).then( result => {
    console.log("sent:", result.sent.length);
    console.log("failed:", result.failed.length);
    console.log(result.failed);
});

service.shutdown();
