无法在nodejs后台获取令牌

Question

我过去常常使用以下代码来获取我的登录令牌：

1const { authSecret } = require('../.env');
2const jwt = require('jwt-simple');
3const bcrypt = require('bcrypt-nodejs');
4
5module.exports = app => {
6  const signin = async (req, res) => {
7    if (!req.body.email || !req.body.password) {
8     return res.status(400).send('Enter user and password ');
9    };
10
11    const user = await app.db('users')
12      .where({ email: req.body.email })
13      .first()
14
15    if (!user) return res.status(400).send('User not found!');
16
17    const isMatch = bcrypt.compareSync(req.body.password, user.password);
18    if (!isMatch) return res.status(401).send('Invalid email/password!');
19
20    const now =  Math.floor(Date.now() / 1000);
21
22    const payload = {
23      id: user.id,
24      name: user.name,
25      email: user.email,
26      age: user.age,
27      city: user.city,
28      iat: now,
29      exp: now + (60 * 60 * 24 * 7)
30    };
31
32    res.json({
33      ...payload,
34      token: jwt.encode(payload, authSecret)
35    })
36  };
37
38  const validadeToken = async (req, res) => {
39    const userData = req.body || null;
40      try {
41        if (userData) {
42            const token = jwt.decode(userData.token, authSecret)
43            if(new Date(token.exp * 1000) > new Date()) {
44              req.send(true)
45            }
46        }
47      } catch (e) {
48        console.log('Inspired token');
49      };
50
51      res.send(false);
52  };
53
54  return { signin, validadeToken };
55}
56

但是昨天我尝试用"bcrypt-nodejs": "^0.0.3"和"jwt-simple": "^0.5.6"创建一个新的节点项目，但是现在当我尝试登录我的后端并得到没有出现的令牌时，我得到了这个错误消息

错误消息：

(node:13188) UnhandledPromiseRejectionWarning: Error: Require key

有人知道我应该怎么做才能得到这个登录令牌吗？

Answer 1

您的authSecret变量看起来是undefined，因此当您在第34行的Error: Require key调用期间尝试将其用作键时，会导致jwt.encode(payload, authSecret)错误。

由于您已经有了一个.env文件，因此我建议您在https://www.npmjs.com/package/dotenv中使用dovenv模块

因此，假设您的.env文件位于项目的根目录中。将您的非结构化导入const { authSecret } = require('../.env');替换为

require('dotenv').config();

const authSecret = process.env.authSecret;

(显然，使用.env文件中定义的任何环境变量替换authSecret )。另外，仅供参考，将环境变量设置为大写并用下划线分隔是一种惯例。例如AUTH_SECRET
