javascript - ExpressJs + Passport.js + MySQL 身份验证

标签 javascript mysql node.js passport.js

每当我尝试通过本地主机注册任何用户时，它都不会创建数据库，我已经厌倦了在 mysql 中运行 schema.sql 文件，它工作正常，但之后我也无法注册。我已经给出了我的完整代码，所以有人可以帮助我解决这个问题吗？

最佳答案

Bookself 与 knex 配合良好，因此首先使用以下命令安装 knex

npm install --save knex

安装后，更改您的 db.js 文件，如下所示

    var knex = require('knex')({
        client: 'mysql',
        connection: {
            host: 'localhost',
            user: 'deen',
            password: 'deen',
            database: 'lttp',
            charset  : 'utf8'
        }
    });

    var Bookshelf = require('bookshelf')(knex);

    module.exports.DB = Bookshelf;

在 package.json 中将 Bookself 版本更改为 *。您的 package.json 应该具有以下依赖项列表。

 {
      "name": "passport_mysql_express_auth",
      "description": "ExpressJs + Passport.js + MySQL Authentication",
      "version": "1.0.0",
      "author": "",
      "main": "app.js",
      "dependencies": {
        "bcrypt-nodejs": "*",
        "body-parser": "*",
        "bookshelf": "*",
        "cookie-parser": "*",
        "ejs": "*",
        "express": "4.x",
        "express-session": "*",
        "knex": "*",
        "mariasql": "^0.2.6",
        "mysql": "*",
        "passport": "*",
        "passport-local": "*"
      }
 }
