egg-token

Egg.js middleware that uses encrypted token to authenticate.

Install

npm i egg-token
# or 
yarn add egg-token

Usage

// {app_root}/config/plugin.js
exports.token = {
  enable: true,
  package: 'egg-token'
};

Configuration

// {app_root}/config/config.default.js
exports.middleware = ['token'];
 
exports.token = {
  type: 'md5',
 
  apps: {
    felixpy: {
      secret: 'XnMib79vzwP01gtr',
      expires: 30000
    },
    codetrial: {
      secret: 'mi9yNGT6zwrqMv8z',
      expires: 30000
    }
  }
};

type is the algorithm that can be used to generate hash digests.

See crypto.createHash for more detail.

Each key of apps is the application's code, secret is used to generate token and expires is the validity period of the token.

The way to generate tokens is as follows:

const ts = Date.now();
const md5Value = md5(`${APP_CODE}:${ts}:${APP_SECRET}`);
const token = base64Encode(`${APP_CODE}:${ts}:${md5Value}`);

Example

This is an example of using axios to request an api:

const crypto = require('crypto');
const axios = require('axios');
 
const hash = crypto.createHash('md5');
 
const APP_CODE = 'felixpy';
const APP_SECRET = 'XnMib79vzwP01gtr';
 
const ts = Date.now();
const md5Value = hash.update(`${APP_CODE}:${ts}:${APP_SECRET}`).digest('hex');
 
const token = Buffer.from(`${APP_CODE}:${ts}:${md5Value}`).toString('base64');
 
axios.get('/url/to/your/egg/service', {
  headers: {
    'egg-api-token': token
  }
});
