node.js - hapi-auth-jwt2 无法在 hapi.js 应用程序中工作？

Question

我刚刚开始学习hapi.js 。我正在尝试理解身份验证的代码。这是如何运作的。为此，我关注了hapi-auth-jwt2 。

之后，当我从 postman 调用 API 时，我没有得到任何输出。

这是我的 server.js 文件，我运行 node server.js。

'use strict';

const Hapi = require('@hapi/hapi');
const jwt = require('jsonwebtoken');
const people = {
  1: {
       id: 1,
       name: 'Jen Jones'
  }
};

// bring your own validation function
const validate = async function (decoded, request, h) {
  // do your checks to see if the person is valid    
  if (!people[decoded.id]) {
      return { isValid: false };
  }
  else {
      return { isValid: true };
  }
};

const init = async () => {
  const server = Hapi.server({
      port: 3000,
      host: 'localhost'
  });
  await server.register(require('hapi-auth-jwt2'));
  server.auth.strategy('test', 'jwt',
      {
          key: 'GSFDSFJDSKGJD;GJRTWERIUEWFJDKL;GVCXVNMXCVCNVS;DLGFJKGFJDHGJFKHGJERHTKERHERJHTKREHJ', // Random String
          validate,
          verifyOptions: { algorithms: ['HS256'] }
    });
  server.auth.default('test');


  server.route([
    {
        method: 'GET',
        path: '/restricted',
        config: {
            auth: 'test'
        },
        handler: function (request, h) {
            console.log("request.headers.authorization ::: ", request.headers.authorization);
            const response = h.response({ text: 'You used a Token!' });
            response.header("Authorization", request.headers.authorization);
            return response;
        }
    }
  ]);


  await server.start();
  return server;
};

process.on('unhandledRejection', (err) => {

  console.log(err);
  process.exit(1);
});

init().then(server => {
  console.log('Server running at:', server.info.uri);
})
.catch(err => {
   console.log(err);
});

您需要使用( secret ) key 为每个用户(people)创建一个 token ，例如:

const jwt = require('jsonwebtoken');

(async() => {
  const key = 'GSFDSFJDSKGJD;GJRTWERIUEWFJDKL;GVCXVNMXCVCNVS;DLGFJKGFJDHGJFKHGJERHTKERHERJHTKREHJ';
  const payload = { id: 1, name: 'Jen Jones' };
  const token = await jwt.sign(payload, key);
  console.log(token);
})();

这是给定负载的 token :

$ node auth.js
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwibmFtZSI6IkplbiBKb25lcyIsImlhdCI6MTU3ODQ5MzQwOH0._kFvxkURRmzq4DgAEzAURca9yIv6KCf7MsolCiWsmRY

token 包含有效负载，再次使用相同的 key 在 validate 中检查有效负载(实际上只需 id 就足够了)。现在使用用户的 token 访问受限路由 { id: 1, name: 'Jen Jones' }:

$ curl -v -H "Authorization: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwibmFtZSI6IkplbiBKb25lcyIsImlhdCI6MTU3ODQ5MzQwOH0._kFvxkURRmzq4DgAEzAURca9yIv6KCf7MsolCiWsmRY"   http://localhost:3000/restricted
