# 未读消息数回调

当客服人员回复了用户的消息后,用户可以收到未读消息的提醒,即使当前并没有展示 AIHelp 的页面。

你可以通过每五分钟一次的轮询作业或者第三方推送实现这个功能。

提示

此功能默认为关闭状态,如有需要,请联系 AIHelp 运营人员开启此功能。

# 轮询方案

注意

AIHelp 默认使用随机生成的 deviceId 作为 userId 进行未读消息数量的轮询。

所以,在你将正确的 userId 同步给 AIHelp 之前,未读消息数量可能会不准确。

# API

# startUnreadMessageCountPolling

调用此方法可以启动未读消息数量的轮询作业,请确保初始化成功之后再调用此方法

void AIHelp_onInitializationCallback() {
    // Sync userId info to AIHelp via updateUserInfo API
    [AIHelpSupportSDK updateUserInfo:[[[AIHelpUserConfigBuilder alloc] init] build]];

    // Start polling
    [AIHelpSupportSDK startUnreadMessageCountPolling:unreadMessageNumCallBack];
}

方法内部每 5 分钟主动拉取一次当前用户的未读消息数量,并在以下两种情况时将结果返回给调用者:

1、有进行中客诉的用户收到新消息时,返回该用户累计未读的消息数量;

2、用户打开客服会话窗口时,返回数字 0 以标记用户已读当前消息。

# 参数释义

# onUnreadMessageCountCallback

  • 类型:(void(*)(int unreadCount))
  • 详情:必传参数。 未读消息数量的回调。

# 推送方案

下面以 APNs 平台为例,说明如何利用第三方推送平台实现应用内未读消息的回调。

1、注册 APNs:

#import <UserNotifications/UserNotifications.h>
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    if (@available(iOS 10.0, *)) {
        [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert completionHandler:^(BOOL granted, NSError * _Nullable error) {
            if (granted) {
                // The user has allowed push permissions
            }
        }];
    } else {
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    }
}

2、在代码中调用推送相关的方法,将用户的推送标识以及推送平台告知 AIHelp:

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
   if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 13) {
       if (![deviceToken isKindOfClass:[NSData class]]) {
           return;
       }
       const unsigned *tokenBytes = (const unsigned *)[deviceToken bytes];
       NSString *strToken = [NSString stringWithFormat:@"%08x%08x%08x%08x%08x%08x%08x%08x",
                             ntohl(tokenBytes[0]), ntohl(tokenBytes[1]), ntohl(tokenBytes[2]),
                             ntohl(tokenBytes[3]), ntohl(tokenBytes[4]), ntohl(tokenBytes[5]),
                             ntohl(tokenBytes[6]), ntohl(tokenBytes[7])];
       token = strToken;
   } else {
       token = [NSString stringWithFormat:@"%@", deviceToken];
       token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
       token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
       token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
   } 
   AIHelpUserConfigBuilder *userConfigBuider = [[AIHelpUserConfigBuilder alloc] init];
   userConfigBuider.userId = @"userId";
   [AIHelpSupportSDK updateUserInfo:userConfigBuider.build];
   [AIHelpSupportSDK setPushToken:token pushPlatform:AIHelpTokenPlatformAPNS];
}

3、在回调中解析 AIHelp 的推送:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    NSDictionary *data = userInfo[@"data"];
    if (data && [data[@"elva"] isEqualToString:@"yes"]) {
        // alert your users that he/she has received a new message
    }
}

4、AIHelp 推送数据格式如下:

{
    "to":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification":{
        "body":"This is your new message content",
        "title":"customer service sends you a message.",
        "sound":"Enabled",
        "priority":"high",
        "uid":"..."
    },
    "data":{
        "body":"This is your new message content",
        "title":"customer service sends you a message.",
        "uid":"...",
        "elva":"yes",
        "entry_tag":"..."
    }
}
