Reactjs 套接字io客户端包上的连接（请求）过多

我使用“socket.io客户端”：“2.2.0”，即package.json上的socket io客户端版本

import io from "socket.io-client";
useEffect(() => {
    let socket = io(socketUrl()); //here goes the url
    socket.on('connect', () => {
        socket.emit('authentication',
            {token: localStorage.getItem(`Bearer`), user_id: 0})

    });
    socket.on("connect_error", (err) => {
        console.log(`connect_error due to ${err.message}`);
    });
    socket.on('authenticated', (obj) => {
        socket.emit('start_marking', {token: localStorage.getItem(`Bearer`)});
    });
    socket.on('mark_payload', data => {
        //some functions to manipulate data....
    });
    socket.on('unauthorized', err =>
        console.log("There was an error with the authentication:", err.message));
},[])

这里的问题是什么，所以我得到了这些问题
