【问题描述】：
我已经尝试了一切，我不能再浪费时间了，请需要帮助，我一直在尝试运行这篇文章中的代码：https://medium.com/@mogold/nodejs-socket-io-express-multiple-modules-13f9f7daed4c，我一直在尝试运行代码这篇文章，我非常喜欢它，因为我认为它非常适合大型项目，当我想连接它时出现问题，向我抛出以下错误： 控制台： 我已经尝试设置在我的应用程序的标题中，我尝试了从类似问题中读取的代码，但没有一个有效，我将 server.ts、socket.ts、job.ts 和 routes.ts 的条件留给你，我希望你能请帮帮我：c
server.ts
import express from "express";
const http = require("http");
import { router} from './routes/routes';
import bodyParser from "body-parser";
import morgan from "morgan";
import { PORT} from "./core/utils/config"
import errorMiddleware from './core/middleware/error.middleware';
import socket from "./socket";
const app = express();
const server = http.createServer(app);
app.use(bodyParser.json());
app.use(router);
app.use(morgan("dev"));
app.use(errorMiddleware);
app.listen(3000, ()=> console.log("[SERVER] list is running in port http://localhost:"+PORT));
socket.connect(server);
socket.ts
let connection: any = null;
export class Socket {
socket: any;
constructor() {
this.socket = null;
}
connect(server: any) {
const io = require("socket.io").listen(server);
io.on("connection", (socket: any) => {
this.socket = socket;
});
}
emit(event: any, data: any) {
this.socket.emit(event, data);
}
static init(server: any) {
if (!connection) {
connection = new Socket();
connection.connect(server);
}
}
static getConnection() {
if (connection) {
return connection;
}
}
}
export default {
connect: Socket.init,
connection: Socket.getConnection
}
job.ts
import socket from "../../../socket";
export class JobSockets {
emitUpdate() {
const connection = socket.connection();
if (connection) {
connection.emit("jobs", {
hola: "hola desde mi backend"
});
}
}
}
routes.ts
import express from "express";
import indexAppointment from "../features/Appointment/routes/index";
import indexUser from "../features/User/routes/index";
import cors from "cors";
const router = express.Router();
const options: cors.CorsOptions = {

从“../features/Appointment/routes/index”导入indexAppointment；

router.use("/appointment",deleteAppoinment);
export default router;
从“../features/User/routes/index”导入 indexUser；
import expres from "express"
import createUser from "./createUser/create_user";
import deleteUser from "./deleteUser/delete_user";
import updateUser from "./updateUser/update_user";
import getUsers from "./getUser/get_user";
import createUserInfoAppointment from "./createUserInfoAppointment/create_user_info_appointment";

const router = expres.Router();

router.use("/user",getUsers);
//managment use case
router.use("/user",createUserInfoAppointment);

【问题讨论】：
-
您似乎没有任何端点可以从定义的前端命中。你能分享 indexAppointment 和 indexUser 的内容吗？另外 /socket.io 不应该是前端命中的内容，您可以将自定义路径传递给套接字连接以进行测试。您将需要在代码中定义该子路径。 socket.io/docs/client-api 看自定义路径。

我刚刚更新了它，实际上对它们进行了索引，我用来将逻辑与用户路径和约会分开
