将数据发送给特定用户（套接字上缺少错误处理程序）

Question

我想将数据发送到服务器上连接的特定客户端。

我有这个架构：

 <form class="register-store">
                            <div class="row">
                                <div class="col-md-6">
                                    <div class="input-group">
                                        <label for="store_name"><?php esc_attr_e( 'Store Name', 'compare' ) ?> <span class="required">*</span></label>
                                        <input type="text" class="form-control" name="store_name" id="store_name">
                                        <p class="field-description"><?php _e( 'Input name of your store', 'compare' ) ?></p>
                                    </div>
                                </div>
                                <div class="col-md-6">
                                    <div class="input-group">
                                        <label for="store_url"><?php esc_attr_e( 'Store URL', 'compare' ) ?> <span class="required">*</span></label>

                                <div class="col-md-6">
                                    <div class="input-group">
                                        <label for="store_logo"><?php esc_attr_e( 'Store Logo URL', 'compare' ) ?> <span class="required">*</span></label>
                                        <input type="text" class="form-control" name="store_logo" id="store_logo">
                                        <p class="field-description"><?php _e( 'Input link to your store logo', 'compare' ) ?></p>
                                    </div>

我目前有以下代码：

chat = {
    rooms: [
        {
            users: [
                {
                    client: {/* socket.io client */},
                    pseudo: ''
                }
                ...
            ],
            messages: [...]
        }
        ...
    ]
}

但是当我尝试运行代码时（当客户端发送消息时），我遇到了服务器端错误：var chat = { // ..., sendMessagesTo: function(event, room) { var users = room.users; var msg = room.messages; var len = users.length; for (var i = len; i--;) { users[i].client.emit(event, msg); } }, } io.on('connection', function(client) { // user = {client: client, pseudo: 'somePseudo'}; // user is added in the chat > rooms > users array; chat.sendMessagesTo('newMessage', someSpecificRoom); // ... }); 上缺少错误处理程序。

我希望你有一个解决方案：）。

谢谢！

我不知道发生了什么。它适用于这个解决方案：

io.to(users[i].client.id).emit(event, room.messages);

我将client.id存储为：

user = {client: {id: client.id}, pseudo: data.pseudo};
