首先

我们将介绍如何将在MongoDB Atlas上创建的用户数据存储与Auth0连接，以迁移现有用户到Auth0的步骤。本文是根据原文制作而成，原文请参考此处。验证需要先安装Node.js、NPM，以及已完成获取Auth0免费账户和创建租户的前提。如果您尚未完成，请在参考本文之前先阅读此处的文章进行准备。

验证环境

端末のOS : macOS Mojave 10.14.5

MongoDB Atlas : Version 4.0.9

Mongo Shell : Version 4.0.9

Node.js : 10.15.3

npm : 6.4.1

操作过程

蒙高侧

我们将在终端上安装Mongo Shell。

$ brew install mongodb/brew/mongodb-community-shell

在创建管理员用户时输入设置的密码以进行连接。

$  mongo "mongodb+srv://cluster0-rt8x2.mongodb.net/test" --username auth0-custom-db-user                                                                                 15:59:03

我将在数据库名为auth0-integration、集合名为users的地方分别创建它们。

> use auth0-integration;
> db.createCollection('users');

我会确认是否已创建了 Collection。

> show collections
users

输入样本登录用户。

> db.users.insert(
   [
     { username: "a.user@spam4.me", password: "som3Passw0rd!" },
     { username: "another.user@spam4.me", password: "newPassw0rd!" },
     { username: "yet.another.user@spam4.me", password: "an0th3rPwd!" }
   ]
)

我将确认是否成功投入。

> db.users.find();
{ "_id" : ObjectId("5cf4c9c1e6e0be4e6822b4c8"), "username" : "a.user@spam4.me", "password" : "som3Passw0rd!" }
{ "_id" : ObjectId("5cf4c9c1e6e0be4e6822b4c9"), "username" : "another.user@spam4.me", "password" : "newPassw0rd!" }
{ "_id" : ObjectId("5cf4c9c1e6e0be4e6822b4ca"), "username" : "yet.another.user@spam4.me", "password" : "an0th3rPwd!" }

只需要一个选项的中文释义：Auth0方面。

修改登录脚本并点击“保存”按钮。
– 由于Auth0仅支持Mongo Library 3.1.4（截至2019年6月），请明确指定版本。
– dbHost的格式为“xxxx.mongodb.net”。
– 本文中为了验证目的，密码以明文指定。请在生产环境中添加加密处理。

function login(email, password, callback) {
  const {MongoClient} = require("mongodb@3.1.4");
  const dbUser = "auth0-customdb-user";
  const dbPwd = "xxxx";
  const dbHost = "cluster0-kft70.mongodb.net";
  const dbName = "auth0-integration";
  const usersCollection = "users";

  const uri = `mongodb+srv://${dbUser}:${dbPwd}@${dbHost}/test?retryWrites=true`;
  const client = new MongoClient(uri, { useNewUrlParser: true });

  client.connect(err => {
    if (err) return callback(err);

    const collection = client.db(dbName).collection(usersCollection);

    collection.findOne({username: email, password}, (err, user) => {
      if (err) return callback(err);
      if (!user) return callback("User not found.");

      const profile  = {
        ...user,
        user_id: user.username
      };
      callback(null, profile);
      client.close();
    });
  });
}
undefined
undefined

点击”自定义数据库”选项卡，在”数据库操作脚本”中点击”获取用户”以修正脚本，然后点击”保存”按钮。

function getByEmail(email, callback) {
  const {MongoClient} = require("mongodb@3.1.4");
  const dbUser = "auth0-customdb-user";
  const dbPwd = "xxxx";
  const dbHost = "cluster0-kft70.mongodb.net";
  const dbName = "auth0-integration";
  const usersCollection = "users";

  const uri = `mongodb+srv://${dbUser}:${dbPwd}@${dbHost}/test?retryWrites=true`;
  const client = new MongoClient(uri, { useNewUrlParser: true });

  client.connect(err => {
    if (err) return callback(err);

    const collection = client.db(dbName).collection(usersCollection);

    collection.findOne({username: email}, (err, user) => {
      if (err) return callback(err);
      if (!user) return callback("User not found.");

      delete user.password;
      const profile  = {
        ...user,
        user_id: user.username
      };
      callback(null, profile);
      client.close();
    });
  });
}

请将auth0-react-samples/01-Login/src/Auth/auth0-variables.js.example复制到同一目录下，并创建一个名为auth0-variables.js的文件。

$ cp auth0-variables.js.example auth0-variables.js

请打开auth0-variables.js文件并指定domain和clientId。您可以在”Settings”选项卡中查找到domain和clientId信息。

export const AUTH_CONFIG = {
  domain: 'mokomoko.auth0.com',
  clientId: 'mB44RrIUvRNRpv0VQH1OOnlWicd4xHDP',
  callbackUrl: 'http://localhost:3000/callback'
}
undefined

按照Readme的指示运行示例应用程序。

$ pwd
/tmp/auth0-react-samples/01-Login
$ npm install
$ npm start
undefined
undefined

最后

在本文中，我们介绍了将现有用户迁移到Auth0的步骤，但Auth0也可以继续使用已经使用的外部用户数据存储。在这种情况下，您可以将”Import Users to Auth0″翻转开关关闭，并在Auth0仪表板上设置除登录之外的脚本（例如用户创建、删除和密码更改）。
