Question

这是我的第一个使用vue和nodejs的项目，所以如果我缺少信息，请告诉我。我正在尝试与Laravel，Vue js和Pusher建立群聊。

Database Tables and Relations

我想为每个可用的团队创建一个私人频道。一旦您单击群聊，就会加载并显示现有消息。当您发送消息时，该消息将被添加到消息表中，并且还可以成功发送到pusher，如下所示： Pusher message

该消息还会添加到发件人的消息列表中，但不会添加到其他团队成员上。

Sender

Other team members

新消息仅在其他团队成员重新加载页面时显示。这意味着回声监听器似乎不起作用。我该如何解决？怎么了？

这是我的代码：

ChatApp.vue（根组件）

<template>
<div class="chat-container row">
    <i class="far fa-comments fa-3x"></i>
    <div id="chat-app" class="chat-app">
        <div class="row mx-0 h-100 overflow-hidden">
            <TeamList :teams="teamList" @selected="startConversationWith"/>
            <Conversation :team="selectedTeam" :messages="messages" @new="saveNewMessage"/>
        </div>
    </div>
</div>
</template>

<script>
import MessageList from './MessageList';
import TeamList from './TeamList';
import Conversation from './Conversation';
import MessageTextBox from './MessageTextBox';

export default {
    props: {
        user: {
            type: Object,
            required: true
        }
    },
    data() {
        return {
            messages: [],
            teamList: [],
            selectedTeam: null,
        }
    },
    mounted() {
        Echo.private('messages.1')
            .listen('NewMessage', (e) => {
                this.handleIncoming(e.message);
            });

        axios.get('/teams')
            .then((response) => {
                this.teamList = response.data;
            });
    },
    methods: {
        startConversationWith(team) {
            axios.get('/conversation/' + team.id)
                .then((response) => {
                    this.messages = response.data;
                    this.selectedTeam = team;
                });
        },
        saveNewMessage(text) {
            this.messages.push(text);
        },
        handleIncoming(message) {
            this.saveNewMessage(message);
            return;
        }
    },
    components: {TeamList, MessageList, MessageTextBox, Conversation}
}
</script>

    broadcaster: 'pusher',

    cluster: process.env.MIX_PUSHER_APP_CLUSTER,
    encrypted: true

Answer 1

对于SSL配置，

encrypted设置为true。在false中配置laravel echo时，请尝试将其设置为bootstrap.js

Answer 2

您可以在评论中看到，在bootstrap.js中将加密设置为false可以解决问题

Laravel Echo监听器未监听
