目前我正在尝试这种方式:
io.sockets.on('connection', function (client) {
console.log("client connected: " + client.id);
io.sockets.socket(client.id).emit("connected", client.id);
client.on("sendMessage", function (data) {
//send message code
});
});
我想要的sendMessage代码应该在单独的文件中。那该怎么办?
我尝试了什么:
//in first.js:
var events = require('events');
var em = new events.EventEmitter();
var msg = require('./message.js');
var emitter = msg.em;
io.sockets.on('connection', function (client) {
console.log("client connected: " + client.id);
io.sockets.socket(client.id).emit("connected", client.id);
emitter.emit('sendMessage');
});
//in message.js
client.on("sendMessage", function (data) {
//return "Hello";
//perform db operation
});
是正确还是错误?有人可以帮忙吗? 或者有任何新的正确方法吗?

您可以将处理程序放在其他文件中并导出它。
主要代码:
const sendMessage = require('./send-message');
io.sockets.on('connection', function (client) {
console.log("client connected: " + client.id);
io.sockets.socket(client.id).emit("connected", client.id);
client.on("sendMessage", sendMessage);
});
发送-message.js:
module.exports = function (data) {
//send message code
});
