我试着编写一个聊天应用程序。我使用(服务器端):php、laravel 5.4和pusher,以及(客户端) vue.js和laravel-echo。
我已经做了一个聊天室,什么是“公共聊天室”。现在我在私人聊天室工作。
我的问题:,什么是最佳实践(在客户端),以倾听所有频道的房间,用户属于什么。
我的目标:检查每个私人和公共房间的频道(就像facebook信使网页上的那样)。
现在我在chat-window组件中有了这一点:
created() {
axios.get('/chatroom').then(response => {
this.chatRooms = response.data;
console.log('get /chatroom response: ' + response.data);
});
axios.get('/messages').then(response => {
this.messages = response.data;
console.log('get /messages response: ' + response.data);
});
Echo.join('chatroom')
.here((users) => {
this.usersInRoom = users;
})
.joining((user) => {
this.usersInRoom.push(user);
})
.leaving((user) => {
this.usersInRoom = this.usersInRoom.filter(u => u != user)
})
.listen('MessagePosted', (e) => {
this.messages.push({
message: e.message.message,
user: e.user
});
});
}
});但这只会监听chatroom频道。客户端如何监听所有的聊天室(this.chatRooms)?
事先谢谢你的答案!

因此,我发现每个用户都必须是自己的频道。
然后我修改了我的chat-window组件:
<template lang="html">
<div class="panel panel-default">
<div class="panel-heading" style="height: 60px">
<chat-room-picker :chatrooms="chatRooms" :newmessage="newmessage" :defaultchatroomid="pickedchatroomid" class="pull-left" v-on:chatroompicked="chatroompick"></chat-room-picker>
<chat-room-creator class="pull-right"></chat-room-creator>
</div>
<chat-room :chatroomid="pickedchatroomid" :newmessage="newmessage"></chat-room>
</div>
</template>
<script>
export default {
data() {
return {
userId: loggedUserFS.id,
userName: loggedUserFS.name,
chatRooms: chatRoomsFS,
pickedchatroomid: defaultChatRoomIdFS,
newmessage: {},
}
},
methods: {
chatroompick(id) {
this.pickedchatroomid = id;
},
},
created() {
// this.getCookiesParams();
var tmp = this.chatRooms[0];
this.pickedchatroomid = tmp.id;
var channelName = 'chat-' + this.userId;
console.debug(channelName + ", channel init.");
window.Echo.join(channelName)
.listen('NewMessageEvent', (e) => {
console.debug("incoming message on " + channelName + ": " + JSON.stringify(e));
console.debug(e.message.chatRoom_id + "==" + this.pickedchatroomid);
console.debug(channelName +" : "+ e.message.chatRoom_id + "==" + this.pickedchatroomid);
// TODO: finish it
if(e.message.chatRoom_id == this.pickedchatroomid) { // if the reciced message comes from the pickedchatroom
console.debug("reciced message comes from the pickedchatroom!");
this.newmessage = e;
} else { // if the reciced message does not come from the pickedchatroom
this.newmessage = e;
}
});
}
}
</script>
<style lang="css">
</style>我做了一个chat-room-picker,它是一个下降,你可以用它改变聊天室。还有一个chat-room组件,用于显示当前聊天室的消息。这两个组件中都有vue-watch-es,新消息被更改,聊天室是添加消息(如果消息属于当前聊天室),否则什么也不做,如果消息属于其他房间,chat-room-picker将开始闪烁。
chat-room-picker手表:
watch : {
newmessage : function (value) {
var message = value;
var picker = $(".chatRoomPicker");
//TODO: check that the message belongs to current chat room
picker.addClass("blink");
picker.on("click", function() {
picker.removeClass("blink");
});
}
}聊天室组件的手表部分:
watch : {
chatroomid : function (value) { // if chat-room is changed
this.getChatRoomMessages();
},
newmessage : function(value) { // TODO: here or parent component check the room of the message
console.debug("newmessage received:" + JSON.stringify(value));
var msgTmp = value.message;
msgTmp.user = value.user;
this.messages.push(msgTmp);
}
},服务器端(在控制器中):
broadcast(new NewMessageEvent($message, $user, $usersOfChatRoom));我的broadcastOn NewMessageEvent方法如下所示:
public function broadcastOn()
{
$channels = [];
foreach ($this->usersOfChatRoom as $addressee) {
if($addressee->id != $this->user->id) {
array_push($channels, new PresenceChannel('chat-' . $addressee->id));
}
}
Log::debug("broadcastOn channels: " . json_encode($channels));
return $channels;
//
}我知道它还没有完成,但是我评论了应该在哪里完成代码。
也许这不是最优雅的方式,但它有效。如果其他人有其他解决方案,请分享!
