node.js - 该如何解决？ : if (! options.algorithms)抛出新错误('algorithms should be set');错误:应设置算法

Question

我正在通过PACKT平台(https://github.com/PacktPublishing/Full-Stack-React-Projects-Second-Edition/tree/master/Chapter03%20and%2004/mern-skeleton)了解有关MERN的信息，但是由于发现下一个错误，所以我无法运行代码:

if (!options.algorithms) throw new Error('algorithms should be set');
        
Error: algorithms should be set

[nodemon] app crashed - waiting for file changes before starting... 

我已经在其他类似的出版物中阅读了有关此主题的信息，发现解决方案是修复此代码:

expressJwt({ secret:  process.env.JWT_SECRET, algorithms: ['RS256'] }) 

@Tugayİlik的回复
但是我不知道到底该在哪里添加此代码？

Answer 1

我已经检查过您的文件了。请转到“服务器”文件夹，=>“ Controller ”文件夹=>“auth.controller.js”文件；然后从55-58行向下滚动，您会看到“

const requireSignin = expressJwt({
  secret: config.jwtSecret,
  userProperty: 'auth'
})

使用以下方法进行更改:

const requireSignin = expressJwt({
  secret: config.jwtSecret,
  userProperty: 'auth',
  algorithms: ['HS256'],
});

请告诉我是否可行。一切顺利。
