如何在Typescript項目中使用express-mysql-session？

Question

我正在嘗試在Typescript項目中使用express-session和express-mysql-session。 這是我的代碼的相關部分：

import * as express from "express";
import * as expressSession from "express-session";
import * as expressMySqlSession from "express-mysql-session";

this.express = express();
const sessionStore = new expressMySqlSession(sessionStoreConfig, this.dbConnection);
const sessionHandler = expressSession({
                ...,
                store: sessionStore
            });
this.express.use(sessionHandler);

由於store選項的類型為expressSession.Store | expressSession.MemoryStore | undefined因此無法編譯expressSession.Store | expressSession.MemoryStore | undefined expressSession.Store | expressSession.MemoryStore | undefined expressSession.Store | expressSession.MemoryStore | undefined而sessionStore是類型的MySQLStore 。 我究竟做錯了什么？

問候

Answer 1

嘗試這個：

import * as express        from "express";
import * as expressSession from "express-session";
import expressMySqlSession from "express-mysql-session";

const MySQLStore   = expressMySqlSession(expressSession);
const sessionStore = new MySQLStore(sessionStoreConfig, this.dbConnection);
...

Answer 2

import * as express from 'express';
import * as session from 'express-session';
const MySQLStore = require('express-mysql-session')(session);

import pool from './database';
const sessionStore = new MySQLStore({
  schema: {
    tableName: 'mire_sessions',
    columnNames: {
      session_id: 'session_id',
      expires: 'expires',
      data: 'data'
    }
  }
}, pool);

const app = express();
app.use(session({
  secret: 'z',
  resave: false,
  saveUninitialized: true,
  store: sessionStore
}))

這段代碼對我有用。 但是我不知道為什么

Answer 3

將express-session ， express-mysql-session和@types/express-mysql-session列為依賴項：

類型的當前版本 （大約兩年前）跟蹤舊版本的express-mysql-session ，其中默認導出為class。 幸運的是，此較早版本的庫中有一些向后兼容 ，因此您可以直接實例化它：

import MySQLSessionStore from "express-mysql-session";

const store = new MySQLSessionStore({...});

該庫將為您處理導入express-session依賴項 。

代碼永不說謊！
