Question

我正在尝试使用SockJS为我的wordpress网站制作聊天应用程序。我的问题是客户端连接到服务器后断开连接。我不知道。这是我的服务器和客户端代码。

服务器：

var fetchedResultsController: NSFetchedResultsController<Content>!

我的客户代码：

var http = require('https');
var sockjs = require('sockjs');
var fs = require("fs");
var commands = {
    key: fs.readFileSync('privkey.pem'),
    cert: fs.readFileSync('cert.pem')
};
var clients = [];
var users = [];
var messages = [];


function broadcast(message){
  for (var client in clients){
    clients[client].write(JSON.stringify(message));
  }
}
var echo = sockjs.createServer();
echo.on('connection', function(conn) {
clients[conn.id] = conn;
conn.on('data', function(e) {
    var data = JSON.parse(e);
    switch(data.action){
        case "new_user":
            clients[conn.id]["username"]=data.username;
            users[data.username]["avatar"]=data.avatar;
            users[data.username]["url"]=data.url;
        case "new_message":
            data.avatar=users[data.username]["avatar"];
            data.url=users[data.username]["url"];
            messages.unshift(data);
            if(messages.length>100){
                messages.length=100;    
            }
            broadcast(data);
    }

});
conn.on('close', function() {
    delete clients[conn.id];
    delete users[clients[conn.id]["username"]];
});

});
var server = http.createServer(commands);
echo.installHandlers(server, {prefix:'/echo'});
server.listen(9999, '0.0.0.0');

控制台输出如下：

chat.js？ver = 4.5.3：66连接到聊天服务器

chat.js？ver = 4.5.3：71与聊天服务器断开连接

chat.js？ver = 4.5.3：66连接到聊天服务器

chat.js？ver = 4.5.3：71与聊天服务器断开连接

有什么问题？感谢

Answer 1

If you use forever/pm2/smth else then I think problem on server-side

    users[data.username]["url"]=data.url;
    break; // missed!
    case "new_message":

Answer 2

问题是服务器文件上的简单对象语法错误。

连接后SockJS断开连接
