Waiting Room

Функция зала ожидания позволяет организаторам контролировать, кто может присоединиться к встрече. Когда она включена, участники должны дождаться одобрения, прежде чем войти во встречу.

Как работает зал ожидания

После вызова meeting.join(), произойдёт одно из двух событий:

roomJoined - Вам разрешено немедленно присоединиться к встрече
waitlisted - Вы помещены в зал ожидания и должны дождаться одобрения организатора

Используйте meeting.self.roomState для отслеживания состояния пользователя во встрече.

Состояния зала ожидания

Поток состояний

        join()
          ↓
    [waitlisted]  ←------ (host rejects)
          ↓                     ↓
   (host accepts)           [rejected]
          ↓
      [joined]

Отслеживание изменений состояния

Событие присоединения

Срабатывает, когда локальный пользователь успешно присоединяется к встрече.

Отслеживайте, когда локальный пользователь присоединяется к встрече:

import { useRealtimeKitSelector } from "@cloudflare/realtimekit-react";
import { useEffect } from "react";

function MeetingStatus() {
	const roomState = useRealtimeKitSelector((m) => m.self.roomState);
	const joined = roomState === "joined";

	useEffect(() => {
		if (joined) {
			console.log("Successfully joined the meeting");
		}
	}, [joined]);

	return joined ? <div>You are in the meeting</div> : null;
}

Как вариант, используйте обработчики событий:

import { useRealtimeKitClient } from "@cloudflare/realtimekit-react";

useEffect(() => {
	if (!meeting) return;

	const handleRoomJoined = () => {
		console.log("Successfully joined the meeting");
	};

	meeting.self.on("roomJoined", handleRoomJoined);

	return () => {
		meeting.self.off("roomJoined", handleRoomJoined);
	};
}, [meeting]);

meeting.self.on("roomJoined", () => {
	// Local user is in the meeting
	console.log("Successfully joined the meeting");
});

meeting.addMeetingRoomEventListener(object : RtkMeetingRoomEventListener {
	override fun onMeetingRoomJoinCompleted(meeting: RealtimeKitClient) {
		// Local user is in the meeting
	}
})

extension MeetingViewModel: RtkMeetingRoomEventListener {
	func onMeetingRoomJoinCompleted(meeting: RealtimeKitClient) {
		// Local user is in the meeting
	}
}

Отслеживайте, когда локальный пользователь присоединяется к встрече:

import { useRealtimeKitSelector } from "@cloudflare/realtimekit-react-native";
import { useEffect } from "react";

function MeetingStatus() {
	const roomState = useRealtimeKitSelector((m) => m.self.roomState);
	const joined = roomState === "joined";

	useEffect(() => {
		if (joined) {
			console.log("Successfully joined the meeting");
		}
	}, [joined]);

	return joined ? <Text>You are in the meeting</Text> : null;
}

Как вариант, используйте обработчики событий:

import { useRealtimeKitClient } from "@cloudflare/realtimekit-react-native";

useEffect(() => {
	if (!meeting) return;

	const handleRoomJoined = () => {
		console.log("Successfully joined the meeting");
	};

	meeting.self.on("roomJoined", handleRoomJoined);

	return () => {
		meeting.self.off("roomJoined", handleRoomJoined);
	};
}, [meeting]);

Waitlisted Event

Срабатывает, когда локальный пользователь помещается в зал ожидания.

Отслеживайте, когда локальный пользователь находится в зале ожидания:

function WaitingRoomStatus() {
	const roomState = useRealtimeKitSelector((m) => m.self.roomState);
	const isWaitlisted = roomState === "waitlisted";

	useEffect(() => {
		if (isWaitlisted) {
			console.log("You are in the waiting room");
		}
	}, [isWaitlisted]);

	return isWaitlisted ? <div>Waiting for host approval...</div> : null;
}

Как вариант, используйте обработчики событий:

useEffect(() => {
	if (!meeting) return;

	const handleWaitlisted = () => {
		console.log("You are in the waiting room");
	};

	meeting.self.on("waitlisted", handleWaitlisted);

	return () => {
		meeting.self.off("waitlisted", handleWaitlisted);
	};
}, [meeting]);

meeting.self.on("waitlisted", () => {
	// Local user is waitlisted
	console.log("You are in the waiting room. Waiting for host approval...");
});

meeting.addSelfEventListener(object : RtkSelfEventListener {
	override fun onWaitListStatusUpdate(waitListStatus: WaitListStatus) {
		when (waitListStatus) {
			WAITING -> {
				// Local user is in the waiting room
			}
			REJECTED -> {
				// Local user's join room request was rejected by the host
			}
			NONE, ACCEPTED -> {
				// Local user is not in the wait list or was already accepted
			}
		}
	}
})

extension MeetingViewModel: RtkSelfEventListener {
	func onWaitListStatusUpdate(waitListStatus: WaitListStatus) {
		switch waitListStatus {
		case .accepted:
			// Local user's join room request was accepted by the host
		case .waiting:
			// Local user is in the waiting room
		case .rejected:
			// Local user's join room request was rejected by the host
		default:
			return .none
		}
	}
}

Отслеживайте, когда локальный пользователь находится в зале ожидания:

function WaitingRoomStatus() {
	const roomState = useRealtimeKitSelector((m) => m.self.roomState);
	const isWaitlisted = roomState === "waitlisted";

	useEffect(() => {
		if (isWaitlisted) {
			console.log("You are in the waiting room");
		}
	}, [isWaitlisted]);

	return isWaitlisted ? <Text>Waiting for host approval...</Text> : null;
}

Как вариант, используйте обработчики событий:

useEffect(() => {
	if (!meeting) return;

	const handleWaitlisted = () => {
		console.log("You are in the waiting room");
	};

	meeting.self.on("waitlisted", handleWaitlisted);

	return () => {
		meeting.self.off("waitlisted", handleWaitlisted);
	};
}, [meeting]);

Событие Rejected

Срабатывает, когда организатор отклоняет запрос на вход.

Отслеживайте, когда организатор отклоняет запрос на вход:

function RejectionStatus() {
	const roomState = useRealtimeKitSelector((m) => m.self.roomState);
	const rejected = roomState === "rejected";

	useEffect(() => {
		if (rejected) {
			console.log("Your entry request was rejected");
		}
	}, [rejected]);

	return rejected ? <div>Your entry was rejected by the host</div> : null;
}

Как вариант, используйте обработчики событий:

useEffect(() => {
	if (!meeting) return;

	const handleRoomLeft = ({ state }) => {
		if (state === "rejected") {
			console.log("Your entry request was rejected");
		}
	};

	meeting.self.on("roomLeft", handleRoomLeft);

	return () => {
		meeting.self.off("roomLeft", handleRoomLeft);
	};
}, [meeting]);

meeting.self.on("roomLeft", ({ state }) => {
	if (state === "rejected") {
		// Host rejected the entry
		console.log("Your entry request was rejected");
	}
});

Когда организатор отклоняет запрос на вход, onWaitListStatusUpdate колбэк вызывается с WaitListStatus.REJECTED:

meeting.addSelfEventListener(object : RtkSelfEventListener {
	override fun onWaitListStatusUpdate(waitListStatus: WaitListStatus) {
		when (waitListStatus) {
			WaitListStatus.REJECTED -> {
				// Local user's join room request was rejected by the host
				Log.d("WaitingRoom", "Your entry request was rejected")
			}
			WaitListStatus.WAITING -> {
				// Local user is in the waiting room
			}
			WaitListStatus.ACCEPTED, WaitListStatus.NONE -> {
				// Local user was accepted or not in waitlist
			}
		}
	}
})

Когда организатор отклоняет запрос на вход, onWaitListStatusUpdate колбэк вызывается с WaitListStatus.rejected:

extension MeetingViewModel: RtkSelfEventListener {
	func onWaitListStatusUpdate(waitListStatus: WaitListStatus) {
		switch waitListStatus {
		case .rejected:
			// Local user's join room request was rejected by the host
			print("Your entry request was rejected")
		case .waiting:
			// Local user is in the waiting room
			break
		case .accepted:
			// Local user's join room request was accepted by the host
			break
		default:
			break
		}
	}
}

Отслеживайте, когда организатор отклоняет запрос на вход:

function RejectionStatus() {
	const roomState = useRealtimeKitSelector((m) => m.self.roomState);
	const rejected = roomState === "rejected";

	useEffect(() => {
		if (rejected) {
			console.log("Your entry request was rejected");
		}
	}, [rejected]);

	return rejected ? <Text>Your entry was rejected by the host</Text> : null;
}

Как вариант, используйте обработчики событий:

useEffect(() => {
	if (!meeting) return;

	const handleRoomLeft = ({ state }) => {
		if (state === "rejected") {
			console.log("Your entry request was rejected");
		}
	};

	meeting.self.on("roomLeft", handleRoomLeft);

	return () => {
		meeting.self.off("roomLeft", handleRoomLeft);
	};
}, [meeting]);

Отслеживание состояния через roomState

Также можно напрямую проверить текущее состояние комнаты.

Обработка всех состояний зала ожидания в одном компоненте:

function WaitingRoomManager() {
	const roomState = useRealtimeKitSelector((m) => m.self.roomState);

	switch (roomState) {
		case "init":
			return <div>Connecting...</div>;
		case "waitlisted":
			return <div>Waiting for host approval...</div>;
		case "joined":
			return <div>You are in the meeting</div>;
		case "rejected":
			return <div>Your entry was rejected</div>;
		case "left":
			return <div>You left the meeting</div>;
		case "kicked":
			return <div>You were removed from the meeting</div>;
		case "ended":
			return <div>The meeting has ended</div>;
		case "disconnected":
			return <div>Connection lost</div>;
		default:
			return null;
	}
}

const currentState = meeting.self.roomState;

if (currentState === "waitlisted") {
	console.log("Waiting for approval");
} else if (currentState === "joined") {
	console.log("In the meeting");
} else if (currentState === "rejected") {
	console.log("Entry was rejected");
}

Используйте показанные выше обработчики событий, чтобы отслеживать изменения состояния.

	}
}

Действия организатора

Организаторы могут управлять запросами на вход в зал ожидания с помощью методов управления участниками. См. Удалённые участники подробнее о:

acceptWaitingRoomRequest(participantId) - Принять участника из зала ожидания
rejectWaitingRoomRequest(participantId) - Отклоните запрос участника на вход

Пример: хост принимает участников

Лучшие практики

Давайте чёткую обратную связь - Покажите пользователям, что они находятся в зале ожидания и ждут одобрения
Определение ожиданий - Сообщите пользователям, что их запрос рассматривается
Корректная обработка отказа - Укажите дружелюбное сообщение на случай отказа во входе
Отслеживание изменений состояния - Подпишитесь на изменения состояния зала, чтобы соответствующим образом обновлять интерфейс
Проверьте разрешения - Убедитесь, что в пресете вашего приложения настроены необходимые разрешения для использования функций зала ожидания
