# 未读消息
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。
你可以通过主动拉取或者第三方推送实现这个功能。
# 主动拉取
# API
# fetchUnreadMessageCount / fetchUnreadTaskCount
调用此方法可以主动拉取当前用户的未读消息数量。
[AIHelpSupportSDK fetchUnreadMessageCount];
[AIHelpSupportSDK fetchUnreadTaskCount];
你可以在任意时间调用该 API 查询当前用户的未读信息,但请注意:
- 上述方法内部都有默认的频率限制:
在限制期内的重复调用,会返回上一次的查询结果;在开发阶段,可以通过日志查看距离下一次有效调用的时间。
- 该方法会在以下情况返回 0,以通知调用者当前用户没有未读消息:
- 用户没有进行中客诉或进行中工单时;
- 用户打开客服会话窗口或已读所有工单信息时;
# 事件
通过监听 AIHelpEventMessageArrival
和 AIHelpEventUnreadTaskCount
事件,你可以收到当前用户的未读消息情况:
void listener(const char *eventData, void (*acknowledge)(const char *ackData)) {
// `eventData`: { "eventType": 5, "msgCount": 1 }
// `eventData`: { "eventType": 8, "taskCount": 1 }
}
[AIHelpSupportSDK registerAsyncListener:listener eventType:AIHelpEventMessageArrival];
[AIHelpSupportSDK registerAsyncListener:listener eventType:AIHelpEventUnreadTaskCount];
# 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":"..."
}
}
