TypeError:“摘要"参数是必需的，并且不能不确定 [英] TypeError: The "digest" argument is required and must not be undefined

问题描述

通过 http://localhost:3000/auth/register ，这是我使用mean init命令创建的. pbkdf2或crypto正在生成错误，我不知道在哪里查找.

I am getting subject error while registering a simple Mean Application through http://localhost:3000/auth/register, that I have simply created using mean init command. pbkdf2 or crypto is generating the error and I have no idea where to look for it.

我做了很多不同的事情，例如清除npm缓存，使用npm重新安装等.请帮帮我.以下是更多信息.

I have done lots of different things like cleared npm cache, reinstalled using npm etc. Please help me out. Following is some more information.

Mean --version: 0.12.15
npm --version: 5.0.3
node --version: v8.1.0
bower --version: 1.8.0
gulp --version: CLI and Local: 3.9.1

model.UserSchema.methods.hashPassword的代码(D:\ Projects \ Mean \ CampaignBuilder \ node_modules \ meanio-users \ server \ models \ user.js)

Code for model.UserSchema.methods.hashPassword (D:\Projects\Mean\CampaignBuilder\node_modules\meanio-users\server\models\user.js)

/**
 * Hash password
 *
 * @param {String} password
 * @return {String}
 * @api public
 */
UserSchema.methods.hashPassword = function(password) {
  if (!password || !this.salt) return '';
  var salt = new Buffer(this.salt, 'base64');
  return crypto.pbkdf2Sync(password, salt, 10000, 64).toString('base64');
};

注册页面调用 http://localhost:3000/api/register 并生成500 Internal Server Error

推荐答案

对于每个crypto.pbkdf2Sync方法，您缺少最后一个参数digest，因此会显示错误.

Per the crypto.pbkdf2Sync method you are missing the final argument which is digest, thus the error being displayed.

crypto.pbkdf2

通过进一步研究，您还可以看到Node v6.0中需要摘要参数.

Also with further investigation you can see that the digest argument was required in Node v6.0.

以前的默认设置似乎是'sha1'.

The previous default seems to have been 'sha1'.
