【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

    推送实现流程.png
    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 <UserNotifications/UserNotifications.h>
    
    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();
