猫鼬查询（Regex）（MongoDB和NodeJS）

Question

我想知道如何将正则表达式更改为 / ^ email。* /

我遇到困难，您能帮我吗？

// Retrieve all apis from the database.
exports.findAllPasswords = (req, res) => {
  const password = req.query.password;
  var condition = password ? { password: { $regex: new RegExp(password), $options: "i" } } : {};
  if (!password)
  res.json({ message: "Password param missing!" });

  api.find(condition)
    .then(data => {
    res.send(data);
    })
    .catch(err => {
      res.status(500).send({
        message:
          err.message || "Some error occurred while retrieving apis."
      });
    });
};
