please refer to sanitize npm package for your request object Link: https://www.npmjs.com/package/sanitize

CodePudding user response：

You can use lodash to do that sanitize process, in the following way.

const _ = require('lodash');
function sanitize(body, values) {
  return _.pick(req.body, values);
}
console.log(sanitize(req.body, ['name', 'email', 'password']));

If you are using express you can the following middleware as follow:

const validatorFunc = (values) => {
  return (req,res,next) => {
    const data = _.pick(req.body, values);
    req.body = data;
    next();
  }
}
