我尝试编写聊天应用程序代码。我使用(在服务器端):php
laravel 5.4
和pusher
以及(在客户端)vue.js
和laravel-echo
。
我已经建立了一个聊天组,什么是“公共聊天室”。现在我正在私人聊天室工作。
我的问题:最好的做法是(在客户端)听取用户所属房间的所有频道。
我的目标:检查(如在facebook Messenger网页上)私人和公共房间的每个频道。
现在我在chat-window
组件中有这个:
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
});
});
}
});
但是这只会监听chatroom
频道。客户如何收听所有聊天室(this.chatRooms
)?
提前感谢答案!
答案 0 :(得分:1)
所以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
什么是下拉菜单,你可以用它来改变聊天室。还有一个chat-room
组件,用于显示当前聊天室的消息。两个组件中都有vue-watch
- es并且新消息被更改,聊天室添加消息(如果消息属于当前聊天室),否则不执行任何操作,{{1如果邮件属于其他房间,则开始闪烁。
chat-room-picker
注意:
chat-room-picker
聊天室组件的监视部分:
watch : {
newmessage : function (value) {
var message = value;
var picker = $(".chatRoomPicker");
//TODO: check that the message belongs to current chat room
picker.addClass("blink");
picker.on("click", function() {
picker.removeClass("blink");
});
}
}
服务器端(在控制器中):
watch : {
chatroomid : function (value) { // if chat-room is changed
this.getChatRoomMessages();
},
newmessage : function(value) { // TODO: here or parent component check the room of the message
console.debug("newmessage received:" + JSON.stringify(value));
var msgTmp = value.message;
msgTmp.user = value.user;
this.messages.push(msgTmp);
}
},
broadcast(new NewMessageEvent($message, $user, $usersOfChatRoom));
的{{1}}方法如下所示:
broadcastOn
我知道它没有完成,但我评论了应该在哪里完成代码。
它可能不是最优雅的方式,但它有效。如果其他人有其他解决方案请分享!
