Nodejs Error: Packets out of order. Got: 0 Expected: 244

Question

过去 10 天我一直在努力解决这个问题。我尝试了在 google.

上找到的所有内容

我搜索并尝试了很多方法，但没有得到任何合适的解决方案。

晚上在服务器运行“npm start”后，我在早上发现了这个错误。

throw er; // Unhandled 'error' event
    ^

我的Sql连接文件：

const Sequelize = require('sequelize')
const dotenv = require('dotenv');
dotenv.config();

const sequelize =
  new Sequelize(process.env.DBNAME, process.env.DBUSER, process.env.DBPASS,
    {
      host: process.env.HOST,
      port: process.env.HOST_PORT,
      dialect: 'mysql',
      operatorsAliases: 0, //false,
      timezone: "+06:00",

      pool: {
        max: 5,
        min: 0,
        acquire: 30000,
        idle: 10000,
      }
    }
  )

module.exports = sequelize;

我的 app.js 文件：

const express = require('express');
var cookieParser = require("cookie-parser");
const cors = require('cors');
const app = express();

app.use(cors());
app.use(express.json({ limit: "50mb" }));
app.use(express.urlencoded({ limit: "50mb", extended: false /*, parameterLimit: 50000*/ }));
app.use(cookieParser());

const Login = require('./routes/mysql-login');

app.use('', Login);

module.exports = app;

我的最终连接文件：

var app = require("../server");
var debug = require("debug") // ("rest-api-nodejs-mongodb:server");
const db = require("../database/db");
var http = require("http");
const fs = require('fs');
var port = normalizePort(process.env.PORT || "3000");
app.set("port", port);
var server = http.createServer(app);

setConnection();

server.listen(port);
server.on("error", onError);
server.on("listening", onListening);


function setConnection() {
  db.sync()
    .then((result) => {
      if (result) {
        console.log("DB Connected");
        console.log(`Nodejs Server started on port: ` + port);
      }
    })
    .catch((err) => {
      console.log("Database Connection Error: ", err);
  })
};


function normalizePort(val) {
  var port = parseInt(val, 10);

  if (isNaN(port)) {
    // named pipe
    return val;
  }

  if (port >= 0) {
    // port number
    return port;
  }

  return false;
}


function onError(error) {
  if (error.syscall !== "listen") {
    console.error(`MySQL Connection Error: ${error}`);    
    throw error;    
  }

  var bind = typeof port === "string" ? "Pipe " + port : "Port " + port;

  // handle specific listen errors with friendly messages
  switch (error.code) {
    case "EACCES":
      console.error(bind + " requires elevated privileges");
      process.exit(1);
      break;
    case "EADDRINUSE":
      console.error(bind + " is already in use");
      process.exit(1);
      break;
    case "ELIFECYCLE":
      console.error("MySQL Connection Lost");
      setConnection();
    default:
      console.error(`MySQL Database Error: ${error}`);
      throw error;
  }
}


function onListening() {
  var addr = server.address();
  var bind = typeof addr === "string" ? "pipe " + addr : "port " + addr.port;
  debug("Listening on " + bind);
}

我修改了 mysql 数据库：

set global net_buffer_length=1000000; 
set global max_allowed_packet=1000000000;

我在 google 上找到的所有内容我都试过了。但最后失败了。那现在怎么办？

用最新版本更新 Nodejs 端的“sequelize”和“mysql2”npm 包暂时解决了这个问题。
