var server = http.createServer(app);
var io = require("socket.io")(server);
app.use(express.json());
const DB = "";
io.on("connection",(socket) => {
console.log("connected!");
});
mongoose.connect(DB).then(() => {
console.log("connection successful");
}).catch((err) => console.log("no connection"));
server.listen(port, "0.0.0.0", () => {

"io.on("connection", ...)" 事件仅在socket.io客户端连接到您的服务器时发生。
这不是与您的其他"console.log()"语句相同的启动消息，因此您只会在socket.io客户端连接后才会看到它。
英文:
The io.on("connection", ...) event only occurs when a socket.io client connects to your server.
It's not a startup message in the same way that your other console.log() statements are so you won't see it until a socket.io client connects.
